The aim of this study was to determine the effect of feeding licuri cake to lambs on the sensory characteristics, physicochemical characteristics and fatty acid (FA) profile of meat from lambs. Forty-four crossbred Santa Ines lambs (21.2 ± 2.70 kg body weight; 6 months old) were housed in individual pens and fed 4 experimental diets, containing 0, 8, 16 or 24% licuri cake (DM basis). The averages concentrations of ash (11.4), pH (5.82), lightness (38.1), cooking loss (26.8) or shear-force resistance (2.48) of lamb meat were not affected by the licuri cake diets. However, there was a linear decrease (P < 0.01) of redness and chroma indexes, lipid and protein contents, whereas the moisture content of the meat (P < 0.001) increased linearly due to the inclusion of licuri cake in lambs' diets. The licuri cake inclusion in the lambs feed linearly increased (P < 0.05) the fatty acids concentrations of C12:0, C17:0, C20:0, C20:1, C18:3, C20:3, C20:4 and ΣPUFA/ΣMUFA ratio, Σω-3 and atherogenicity index (AI). However, C18:1 cis, C20:2, C20:5, ΣMUFA, ΣMUFA/ΣSFA and Σω-6:Σω-3 ratios in the longissimus lumborum of lambs linearly decreased by licuri cake inclusion. There was a quadratic increase (P < 0.05) on C14:0 (maximum point 4.94 g/100 g FAME to 14.5% licuri inclusion), C16:1 (maximum point 8.59 g/100 g FAME to 10.7% licuri inclusion) and enzymatic activities of Δ9-desaturase C16 (maximum point 27.5 g/100 g FAME to 10.6% licuri inclusion) in the longissimus lumborum of lambs fed due to increased concentrations of licuri cake. However, there was a quadratic decrease (P = 0.04) in ΣPUFA/ΣSFA ratio with minimum concentration of 0.63 g/100 g FAME to 11.1% inclusion. The inclusion of licuri cake in the lambs diet did not change (P > 0.05) the concentrations of SFA C10:0, C15:0, C16:0, C18:0, C14:1, MUFA C18:1 trans, PUFA C18:2 cis, CLA, total sum of ΣSFA and ΣPUFA, desirable fatty acids (DFA), hypocholesterolemic:hypercholesterolemic index, and elongase and Δ9-desaturase C18 enzymes. Licuri cake in the lamb diet improved (P < 0.05) meat aroma, flavor and overall acceptance by consumers. Licuri cake inclusion in the diet of lambs improves sensory attributes of meat and the meat fatty acid profile becomes nutritionally healthier for the human diet because do not affect major FA of meat; however, the growth performance of finishing lambs is reduced., Competing Interests: The authors have declared that no competing interests exist.

This study was conducted to test the hypothesis that the inclusion of crude glycerin of up to 21% of DM in the diets of lambs will not compromise variables related to animal production or health. Forty-four uncastrated Santa Inês crossbreed lambs with an average age of 5 mo and a BW average of 23.9 ± 0.34 kg (mean ± SD) were distributed into four treatment groups (11 replicates per group) including 0%, 7%, 14%, or 21% crude glycerin on a DM basis. The inclusion of crude glycerin in the diets promoted a quadratic increase in DM (P = 0.018), CP (P = 0.004), and TDN (P = 0.017). There was a linear decrease (P < 0.001) in NDF and nonfibrous carbohydrate (NFC) intake caused by glycerin in the diets. There was a linear increase (P < 0.001) in ether extract (EE) intake. There was a linear reduction in NDF (P = 0.011) and NFC (P < 0.001) for effective consumption of the diets. There was a linear increase (P < 0.001) in EE effectively consumed by the lambs, and there were no differences in the CP that was effectively consumed (P = 0.267) by glycerin. Digestibility coefficients of DM, CP, NDF, NFC, and TDN presented a linear decrease in crude glycerin inclusion. The EE digestibility presented a linear increase. The inclusion of crude glycerin in the diets promoted a quadratic increase in final BW (P = 0.015), ADG (P < 0.001), and G:F ratio (P < 0.001). There was no effect (P > 0.05) of crude glycerin inclusion in the diets on time spent (%); number of events per day; duration of events (minutes) for feeding, rumination, and idling; number of chews per bolus; or total chewing time for the lambs. The inclusion of crude glycerin in the diets improved feeding efficiency of DM (P = 0.005) and NDF (P = 0.004). The rumination efficiency of DM (P < 0.001) and NDF (P < 0.001) presented a linear decrease. The total protein, albumin, globulin, albumin:globulin ratio, triglycerides, alanine aminotransferase levels, aspartate aminotransferase, and gamma glutamyl transferase serum concentrations did not differ (P > 0.05) through the addition of crude glycerin to the diets of the lambs. However, the crude glycerin in the diets led to a linear decrease in urea-N (P = 0.004) and glucose (P <0.001), as well as a linear increase in the cholesterol (P = 0.043) serum concentrations of the lambs. The recommended inclusion of crude glycerin is up to a 4.7% DM level because of improved performance growth without compromising feeding behavior and blood metabolites.

This study was conducted to test the effect of dietary tannin on the fatty acid profile and sensory attributes of meat from Nellore steers. Thirty-two Nellore bull male were distributed in a completely randomized design and fed diets with condensed tannin extract as follows: 0, 10, 30, and 50 g/kg total DM basis. The physicochemical composition of the meat, lipid oxidation, fatty acid profile, flavor, tenderness, and overall acceptance were evaluated. There was a linear decrease (P ≤ 0.05) on lipid content, tenderness, cooking weight loss, myristic, palmitic, and oleic acids in meat as tannin increased in the diets. The total saturated and monounsaturated fatty acids, the atherogenicity index decreased. However, a linear increase (P ≤ 0.05) was observed for linoleic, linolenic, arachidonic, eicosapentaenoic, and docosapentaenoic acids. The physicochemical characteristic of the meat, such as moisture, ash, and protein contents, water retention capacity, final pH, Warner-Bratzler shear force, collagen, and color indexes (lightness, redness, yellowness, and chrome) did not change with dietary tannin. Also, CLA, n-6:n-3 ratio, Δ 9 -desaturase, and elongase activity were not different among diets. In conclusion, condensed tannin linearly increases unsaturated fatty acids and decreases the atherogenicity index of meat; thus, it can be recommended at the highest level (50 g/kg DM) in the diet of Nellore steers., Practical Application: Agriculture byproducts plays an important part in the diet of ruminant animals and consequently on food chain and has implications for the composition and quality of the livestock products (milk, meat, and eggs) that people consume. Feeding tannin to steers increases the amount of unsaturated fatty acids and meat tenderness, with a concomitant reduction on saturated fatty acids and the atherogenicity index in meat. Thus, we recommend adding tannin to steer diets to reduce the risk factors for cardiovascular diseases in red meat for human consumption., (© 2018 Institute of Food Technologists®.)

This study evaluated the total replacement of soybean meal with peanut cake in the concentrate supplement of lactating cows grazing. Eight crossbred 5/8 Holstein × 3/8 Zebu cows between the 45th and 60th day of lactation and 507 ± 35 kg BW were distributed in a 4 × 4 double Latin square design with four levels of peanut cake (0, 110, 220, and 330 g/kg of the dry matter-DM) as a replacement of soybean meal in the concentrate supplement. The intake of pasture, total (pasture + concentrate), crude protein (CP), neutral detergent fiber (NDF), total digestible nutrients, and digestibility of the DM, CP, ether extract (EE), and NDF was not affected by the replacement of soybean meal with peanut cake. However, the EE (P = 0.83) intake and non-fiber carbohydrate digestibility (P = 0.09) exhibited an increasing linear trend by the peanut cake inclusion. The NDF exhibited a decreasing linear trend (P = 0.07) as the level of peanut cake increased. Production, corrected production, and protein, fat, lactose, total solid, and non-fat solid composition concentrations in the cows' milk were not affected (P > 0.05) by the peanut cake inclusion. The protein/fat ratio exhibited an increasing linear trend (P = 0.082) by the peanut cake inclusion. Peanut cake can completely replace soybean meal in the concentrate mixture because it does not alter dry matter intake, production, and composition of milk, and in addition it can reduce the cost of feeding.

The aim of this study was to determine the effect of the inclusion of sunflower cake in the diets of lambs on meat quality. Forty male, uncastrated Santa Ines lambs with an initial average body weight of 20.9 ± 0.41 kg were used in a completely randomized design with four treatments. The lambs were fed 500 g/kg hay and 500 g/kg concentrate (corn, soybean meal, urea, ammonium sulfate and sunflower cake) in their diet, and the experimental treatments were 0, 10, 20, and 30% sunflower cake inclusion (DM basis). The inclusion of sunflower cake in the diet did not affect (P > 0.05) the content of ash and protein, overall acceptance, or sensory aroma of the lamb meat. Total lipids and moisture content of the longissimus lumborum muscle increased linearly (P ≤ 0.05) with sunflower cake inclusion. The C16:0, ΣSFA, ΣMUFA:ΣSFA ratio, Δ-9 desaturase enzyme and atherogenicity index in the longissimus lumborum muscle decreased linearly (P ≤ 0.05) with sunflower cake inclusion in lamb diets, whereas a linear increase occurred (P ≤ 0.05) in C12:0, C18:0, ΣMUFA, ΣPUFA, ΣPUFA:ΣSFA and ΣPUFA:ΣMUFA ratios, Σn-6, Σn-3, desirable fatty acids, h:H index, elongase activity, and flavor, tenderness and juiciness sensory qualities in lamb meat. Among the panelists, the highest preference (35.9%) was for meat with 30% sunflower cake inclusion in the diet. Sunflower cake up to 30% of total DM can be included in the diet of Santa Ines lambs, because lipid nutritional quality and the sensory qualities of the lamb meat increase, in addition to improvement in nutraceutical compounds, such as the CLA content, and in the AI, PUFA:SFA and PUFA:MUFA ratios, desirable fatty acids content and h:H ratio, which are beneficial to the health of consumers.

An experiment was carried to evaluate the energy and protein requirements for the growth and maintenance of lambs of different sex classes. In all, 38 hair lambs (13.0±1.49 kg initial BW and 2 months old) were allocated in a factorial design with diet restriction levels (ad libitum, 30% and 60% feed restriction) and sex classes (castrated and non-castrated males). Four animals from each sex class were slaughtered at the beginning of the trial as a reference group to estimate the initial empty BW and body composition. The remaining lambs were weighed weekly to calculate BW gain (BWG), and when the animals fed ad libitum reached an average BW of 30 kg, all of the experimental animals were slaughtered. Before slaughter, fasted BW (FBW) was determined after 18 h without feed and water. Feed restriction induced reductions in body fat and energy concentration, whereas water restriction showed the opposite effect, and the protein concentration was not affected. The increase in BW promoted increases in body fat and energy content, and these increases were greater in castrated lambs, whereas the protein content was similar between classes tending to stabilize. The net energy required for gain (NEg) and the net protein required for gain (NPg) were not affected by sex class; therefore, an equation was generated for the combined results of both castrated and non-castrated lambs. The NEg varied from 1.13 to 2.01 MJ/day for lambs with BW of 15 and 30 kg and BWG of 200 g. The NPg varied from 24.57 to 16.33 g/day for lambs with BW of 15 and 30 kg and BWG of 200 g. The metabolizable energy efficiency for gain (k g) was 0.37, and the metabolizable protein efficiency for gain (k pg) was 0.28. The net energy required for maintenance (NEm) and the net requirement of protein for maintenance (NPm) did not differ between castrated and non-castrated lambs, with values of 0.241 MJ/kg FBW0.75 per day and 1.30 g/kg FBW0.75 per day, respectively. The metabolizable energy efficiency for maintenance (k m) was 0.60, and the efficiency of metabolizable protein use for maintenance (k pm) was 0.57. Nutritional requirements for growth and maintenance did not differ between castrated and non-castrated lambs. This study emphasizes the importance of updating the tables of international committees and of including data obtained from studies with sheep breeds raised in tropical conditions, with the purpose of improving the productive efficiency of the animals.

Licuri (Syagrus coronate) cake is a biodiesel by-product used in ruminant feed as a beneficial energy source for supplementation in managed pastures. The objective was to evaluate the performance, digestibility, nitrogen balance, blood metabolites, ingestive behavior and diet profitability of eight crossbred Holstein (3/4)×Gyr (5/8) multiparous cows (480±25 kg BW and 100 days milking) grazing and supplemented with licuri cake partially replacing ground corn and soybean meal in concentrate (0, 200, 400 and 600 g/kg in dry matter (DM)), distributed in an experimental duplicated 4×4 Latin square design. Licuri cake partially replacing ground corn and soybean meal increased (P<0.01) the intake and digestibility of ether extract and decreased the non-fiber carbohydrates; however, there were no influences on the intakes of DM, CP, NDF and total digestible nutrients (TDN). The digestibilities of DM, CP and NDF were not influenced by licuri cake addition. There was a decrease trend on TDN digestibility (P=0.08). Licuri cake replacing ground corn and soybean meal in concentrate did not affect the intake; fecal, urinary and mammary excretions; N balance; and triglycerides concentrations. However, the blood urea nitrogen (P=0.04) concentration decreased with the licuri cakes inclusion in cow supplementation. There was an increasing trend for serum creatinine (P=0.07). Licuri cake inclusion did not affect body condition score, production, yield, protein, lactose, total solids and solid non-fat contents of milk and Minas frescal cheese. There was a linear decrease in average daily weight gain (g/day). The milk fat concentration and cheese fat production (P<0.1) presented a linear increase with partial replacement of ground corn and soybean meal with licuri cakes. The addition of licuri cake did not alter the time spent feeding, ruminating or idling. There was an increasing trend in NDF feeding efficiency (P=0.09). The replacing of ground corn and soybean meal with licuri cake up to 600 g/kg decreased the concentrate cost by US$0.45/cow per day. Licuri cake replacing corn and soybeans (400 g/kg) in concentrate promoted a profit of US$0.07/animal per day. Licuri cake is indicated to concentrate the supplementation of dairy cows with average productions of 10 kg/day at levels up to 400 g/kg in the concentrate supplement because it provides an additional profit of US$0.07/animal per day and increased milk and Minas frescal cheese fat without negative effects on productive parameters.

This study evaluated the performance and carcass characteristics of lambs fed diets with increasing levels of Mimosa tenuiflora (Willd.) hay replacing Buffel grass (Cenchrus ciliaris). Twenty-eight Santa Inês male lambs with an average body weight (BW) of 20.3 ± 1.49 kg(mean ± SD) were allocated in individual stalls and distributed in a completely random design with four treatments (0, 20, 40, and 60 g/100 g total DM M. tenuiflora hay replacing Buffel grass hay in diet) with seven replications. M. tenuiflora hay at the level of 20% dry matter (DM) total replacing Buffel grass hay increased final weight (P = 0.006), total weight gain (P < 0.001), average daily weight gain (ADWG; P < 0.001), DM intake (P < 0.001), and feed efficiency (P < 0.001). Intake of crude protein, NDF ap , ADF ap , ash, ether extract, total and non-fibrous carbohydrates, and total digestible nutrients presented a positive quadratic effect with M. tenuiflora hay replacing Buffel grass hay and 40 g/100 g total DM level presented greater intake. There were positive quadratic effects by M. tenuiflora hay inclusion at 20 g/100 g total DM level on slaughtering weight (P = 0.005), hot carcass weight (P = 0.002), cold carcass weight (P = 0.002), empty body weight (P = 0.001), hot carcass yield (P = 0.002), cold carcass yield (P = 0.003), and increase linear on biological yield (P = 0.003). There was no influence on cooling weight loss (P = 0.284). M. tenuiflora hay may be included in lamb diets at amounts up to 20 g/100 g total DM substitution of Buffel grass hay because increase in the nutrients intake, growth performance, and carcass characteristics.

Background: An experiment was conducted to evaluate the effects of feed restriction (FR) and sex on the quantitative and qualitative carcass traits of Morada Nova lambs. Thirty-five animals with an initial body weight of 14.5 ± 0.89 kg and age of 120 d were used in a completely randomized study with a 3 × 3 factorial scheme consisting of three sexes (11 entire males, 12 castrated males and 12 females) and three levels of feeding (ad libitum - AL and 30% and 60% FR)., Results: Entire males presented greater hot and cold carcass weights ( P  < 0.05), followed by castrated males and females. However, the hot carcass yield was higher for females and castrated males than for entire males. Luminosity values were influenced ( P  < 0.05) by sex, with entire males presenting higher values than castrated males and females. Females showed higher ( P  < 0.05) concentrations of linoleic acid and arachidonic acid in the meat of the longissimus thoracis muscle. The meat of animals submitted to AL intake and 30% FR showed similar ( P  > 0.05) concentrations, and the concentrations of palmitic acid, palmitoleic acid, stearic acid, oleic acid and conjugated linoleic acid were higher ( P  < 0.05) than those of animals with 60% FR. The meat of females had a higher ω6/ω3 ratio and lower h/H ratio, and females had greater levels of feeding. The meat of animals on the 60% FR diet had a greater ω6/ω3 ratio, lower h/H ratio and lower concentration of desirable fatty acids in addition to a greater atherogenicity index (AI) and thrombogenicity index (TI)., Conclusion: Lambs of different sexes had carcasses with different quantitative traits without total influence on the chemical and physical meat characteristics. The lipid profile of the meat was less favorable to consumer health when the animals were female or submitted to 60% feed restriction.

Background: Salted Sun-dried meat is a traditional process of meat salting that can improve quality and overall acceptance. The present study compared the physicochemical and sensory attributes of fresh and salted sun-dried meat from Nellore Zebu (Bos taurus indicus) bulls (n = 32) and evaluated diets containing different levels (0%, 7%, 14% and 21%) of licury cake in diets provided to Nellore finished in a feedlot., Results: Salted sun-dried meat decreased moisture (P < 0.0001) and ether extract (P = 0.0002) contents but increased ash (P < 0.0001) and protein (P < 0.0001) contents compared to fresh meat. The addition of licury resulted in linear increases in moisture (P = 0.02) and quadratic effects on Warner-Bratzler shear force (P < 0.03) in fresh meat. Cooking weight loss (P < 0.0001) and Warner-Bratzler shear force (P = 0.03) were reduced by the manufacturing process of sun-dried meat. Sun-dried meat presented greater color index L * (P = 0.0032), a * (P < 0.0001) and c * (P < 0.0001) values but a lower index color b * (P < 0.0001) value compared to fresh meat. Salted sun-dried meat presented greater sensory characteristic scores compared to fresh meat (P > 0.05)., Conclusion: Licury cake can be used in 21% of dry matter in diets to finish animals in feedlot without lessening the quality fresh meat or sundried meat. Salted sun-dried meat presented a greater overall acceptance. © 2016 Society of Chemical Industry., (© 2016 Society of Chemical Industry.)

This study evaluated the effects of replacing ground corn with buriti oil ( L.) on feed intake and digestibility and on the production, composition, fatty acid profile and sensory characteristics of goat milk. A double Latin square (4 × 4) was used; eight goats were distributed in a completely randomized design. The square comprised four periods and four buriti oil concentration (0.00; 1.50; 3.00 and 4.50% of total DM) replacing corn. Intakes of DM, CP, NDF, ADF, non-fibrous carboydrates (NFC) and TDN were not affected by the replacement of corn with oil in the diet. However, lipids intake was increased ( < 0.01) by 100% in the diet of goats with 4.50% oil inclusion, as total DM. DM and CP digestibility were similar between the buriti oil concentrations. However, lipid digestibility increased linearly ( = 0.01) and may have contributed to a quadratic reduction in NDF digestibility ( = 0.01) and a linear reduction of NFC ( = 0.04) with buriti oil content in the goat feed. Goat milk production, corrected production and chemical composition were not influenced by the concentration of buriti oil replacement; however, milk fat concentration ( = 0.04) and feed efficiency ( < 0.01) increased linearly with the amount of buriti oil in the diet. There was a linear reduction on hypercholesterolemic SFA such as C12:0 ( < 0.01) and C14:0 ( < 0.01) as well as the atherogenic index (AI; < 0.01) with buriti oil inclusion in goat's diet. In contrast, the fatty acids C18:0 ( < 0.01) and C18:1 9 ( < 0.01) increased linearly in the milk of goats that were fed with buriti oil. However, CLA ( < 0.01) varied quadratically; the maximum production of 0.62 g/100 g of fat was observed when using 1.50% buriti oil. The sensory characteristics of the milk were not changed ( > 0.05) by the replacement of corn with buriti oil in the goats' diet. It is recommended to replace corn with buriti oil in goat feed by up to 4.5% of total DM, resulting in improved feed efficiency and milk fat without affecting production; this recommendation satisfies the minimum requirements of the industry and preserves the organoleptic characteristics of the milk and its acceptability for human consumption. In addition, buriti oil replacing ground corn by up to 4.5% DM in the diet of lactating goats decrease medium-chain SFA which are hypercholesterolemic and increase the concentrations of the C18:19, CLA and DFA in goat milk fat, helping to protect against cardiovascular disease.

This study compared the productive and nutritional parameters of milk from crossbred lactating cows managed on Panicum maximum Jacq. cv. Tanzania and with a diet supplemented with different pressed oilseed cakes. The supplements used were as follows: peanut cake, sunflower cake and palm kernel cake for replacement of soybean meal. Sixteen cows with an average weight of 544 ± 57 kg and producing 8 ± 1.4 L of milk per day were used in this study. The animals were randomly assigned to the treatments according to a Latin square design repeated over time, with four treatments, 16 animals and four experimental periods. Supplementation of the diet with peanut cake, sunflower cake and palm kernel cake compared with soybean meal in the diet of cows did not affect the average daily production or composition of the milk. The palm kernel cake promoted an increase in lauric fatty acids (C 12:0 ) and palmitoleic acids (C 16:1 ) (5.02 and 1.65%, respectively) compared with peanut cake and sunflower cake (4.13 and 4.01%, respectively). The levels of oleic fatty acids (C 18:1 ) were higher for the sunflower cake and palm kernel cake supplements (26.01 and 25.01%, respectively) compared with peanut cake (23.11%). The replacement of soybean meal with sunflower cake and palm kernel cake improved the nutritional quality of the milk, with lower concentrations of saturated fatty acids and higher concentrations of unsaturated fatty acids, without compromising the production or nutritional composition of the milk. © 2015 Japanese Society of Animal Science., (© 2015 Japanese Society of Animal Science.)

The experiment was conducted to determine the protein requirements for maintenance (PM) and weight gain (NPg) in Brazilian Somali lambs (n = 48). A database of information on non-castrated rams (n = 48) with an initial body weight (BW) of 13.47 ± 1.76 kg was obtained, and the comparative slaughter technique was used to assess protein requirements. Eight lambs were initially slaughtered and used as a reference for estimation of the empty body weight (EBW) and initial body composition of the remaining animals. The lambs (n = 40) were distributed in a completely randomized block design involving five experimental diets, containing 4.93, 8.65, 9.41, 10.12, and 11.24 MJ/kg dry matter (DM). Daily nitrogen retention (DNR) was calculated as the difference between the final N content in the body minus the initial content estimated from the reference animals, divided by the number of experimental days. PM was estimated from the retained N regression equation as a function of ingested N (g per kg(0.75) EBW/day), extrapolating the equation to the zero level of N intake, followed by multiplication by a factor of 6.25. The protein content of the EBW was reduced from 119.72 to 102.07 g/kg of empty body weight gain (EBG) when BW increased from 13 to 28.70 kg, respectively. The requirement of protein for maintenance was 0.80 g per kg(0.75) EBW/day. Based on information described in the present study, we recommend the value of PM 0.80 g per kg(0.75) EBW/day, for hair sheep Brazilian Somalis raised in tropical regions. We also suggest that hair sheep have different requirements for protein maintenance and gain.

Background: Licuri cake is a biodiesel byproduct and has been tested as an alternative feed additive for use in cattle production. This study analyzed the color, sensory and chemical attributes of burger meat from bovines. Thirty-two young Nellore bulls were used, housed in individual pens and distributed in a randomized experimental design with four treatments: no addition or the addition of 7, 14 or 21% (w/w) licuri cake in the dry matter of the diet., Results: Interactions between the licuri cake level and the physicochemical variables (P > 0.05) were observed. Additionally, an interaction was observed between the licuri cake level and the burger beef color parameter lightness index (L*) (P = 0.0305). The L* value was positively and linearly correlated with the proportion of licuri cake in the diet of young bulls. The level of inclusion of licuri cake did not affect (P > 0.05) the sensory characteristics; the variables were graded between 6 and 7, indicating good overall acceptance., Conclusion: Up to 21% (w/w) licuri cake can be included in the diet of young bulls without negatively impacting on beef burger quality. © 2015 Society of Chemical Industry., (© 2015 Society of Chemical Industry.)

This study aimed to determine the impact of replacing soybean meal with peanut cake in the diets of crossbred Boer goats as determined by carcass characteristics and quality and by the fatty acid profile of meat. Forty vaccinated and dewormed crossbred Boer goats were used. Goats had an average age of 5 mo and an average BW of 15.6 ± 2.7 kg. Goats were fed Tifton-85 hay and a concentrate consisting of corn bran, soybean meal, and mineral premix. Peanut cake was substituted for soybean meal at levels of 0.0, 33.33, 66.67, and 100%. Biometric and carcass morphometric measurements of crossbred Boer goats were not affected by replacing soybean meal with peanut cake in the diet. There was no influence of the replacement of soybean meal with peanut cake on weight at slaughter ( = 0.28), HCW ( = 0.26), cold carcass weight ( = 0.23), noncarcass components of weight ( = 0.71), or muscularity index values ( = 0.11). However, regression equations indicated that there would be a reduction of 18 and 11% for loin eye area and muscle:bone ratio, respectively, between the treatment without peanut cake and the treatment with total soybean meal replacement. The weights and yields of the commercial cuts were not affected ( > 0.05) by replacing soybean meal with peanut cake in the diet. Replacing soybean meal with peanut cake did not affect the pH ( = 0.79), color index ( > 0.05), and chemical composition ( > 0.05) of the meat (). However, a quadratic trend for the ash content was observed with peanut cake inclusion in the diet ( = 0.09). Peanut cake inclusion in the diet did not affect the concentrations of the sum of SFA ( = 0.29), the sum of unsaturated fatty acids (UFA; = 0.29), or the sum of PUFA ( = 0.97) or the SFA:UFA ratio ( = 0.23) in goat meat. However, there was a linear decrease ( = 0.01) in the sum of odd-chain fatty acids in the meat with increasing peanut cake in the diet. Soybean meal replacement with peanut cake did not affect the n-6:n-3 ratio ( = 0.13) or the medium-chain fatty acid ( = 0.76), long-chain fatty acid ( = 0.74), or atherogenicity index values ( = 0.60) in the meat. The sensory attributes of the longissimus lumborum did not differ with the inclusion of peanut cake in the diet as a replacement for soybean meal. These results suggest that based on carcass and meat characteristics, peanut cake can completely substitute soybean meal in the diet of crossbred Boer goats.

This study was conducted to evaluate the effect of multiple stress factors (thermal, nutritional and pregnancy type) on two different native track breeds of ewes as reflected by their adaptive capability under semi-arid environment. The multiple stressor experiment was conducted in twenty-four ewes (12 Santa Inês and 12 Morada Nova ewes). Both heat stress and pregnancy stress was common to all four groups. However, the animals were divided into further two groups within each breed on the basis of nutrition regimen. According the groupings were: Group 1 (Six Santa Ines ewes; heat stress; nutrition at 0.5% of BW; single pregnancy); Group 2 (Six Santa Ines ewes; heat stress; nutrition at 1.5% BW; twin pregnancy); groups Group 3 (Six Morada Nova ewes; heat stress; nutrition at 0.5% of BW; single pregnancy); Group 4 (Six Morada Nova ewes; heat stress; nutrition at 1.5% BW; twin pregnancy). All the animals in the experiment were pregnant. Heat stress was induced by exposing all animals to summer heat stress in outside environment while the nutritional regimen followed was at 0.5% and 1.5% level of body weight (BW) respectively in each breed. The experiment was conducted in a completely randomized design with two breeds, two nutritional treatments and two pregnancy types, 10 repetitions for physiological parameters and six for blood parameters, with repeated measures over time. Physiological parameters (respiratory rate, pulse rate and rectal temperature) were measured with the animals at rest in the morning and afternoon, 0600-0700 and 1300-1400h, respectively, every seven days. Blood samples were collected every 14d for determination of serum glucose, triglycerides, cholesterol, urea and creatinine. We found interaction effect between breed and pregnancy type on respiratory rate and rectal temperature with greater values in Santa Inês ewes than Morada Nova ewes. However, there was no significant fixed effect of pregnancy type and supplementation level on physiological responses of breeds. Environmental factor (period of the day) had influenced the physiological responses of ewes during all gestational period. Santa Inês ewes had greater serum glucose concentration at 105d and 120d of gestation compared to the Morada Nova ewes. Morada Nova ewes had greater concentrations of triglycerides, urea at 120d, 150d and also greater cholesterol at 105d, 135d and 150d of gestation compared with Santa Inês ewes. The present result indicates that thermal condition was most important factor that modified the physiological responses of ewes in a semi-arid tropical environment., (Copyright © 2016 Elsevier Ltd.

This study aimed to determine the impact of the inclusion of licuri cake in the diets of crossbred Santa Inês lambs, based on intake, digestibility, N balance, urea N, and performance. We used 44 male lambs that were vaccinated and wormed, with an average age of 6 mo and an average BW of 21.2 kg ± 2.7 kg. The lambs were fed a mixture of Tifton-85 hay (40%) and a concentrated mixture (60%) composed of ground corn, soybean meal, and mineral premix. For the treatments, licuri cake was added at levels of 0, 8, 16, and 24% of DM, with the licuri cake replacing soybean meal and ground corn. We used 11 lambs per treatment in a randomized design. The lambs were confined for 70 d, and the digestibility trial occurred between Day 40 and Day 55. The increased level of licuri cake inclusion promoted a linear reduction in DM intake ( = 0.00) with a 39% reduction between treatments with the 0 and 24% cakes. On the other hand, ether extract () consumption showed an initial quadratic increase ( = 0.00). The total weight gain and ADG showed a linear decrease ( = 0.00) with the addition of licuri cake. The inclusion of licuri cake linearly enhanced ( = 0.02) the digestibility of CP and EE, whereas the digestibility of other nutrients in lambs remained unchanged ( > 0.05). The licuri cake increase led to a linear decrease ( < 0.05) in the N intake, fecal N, and retained N in lambs. Urinary N was not changed. The slaughter carcass weight, HCW, cold carcass weight, hot carcass yield, and cold carcass yield showed linear decreases ( < 0.05) with the addition of licuri cake. Carcass morphometric measurements were influenced by experimental diets, showing linear decreases ( < 0.05) with the addition of licuri cake to diets. The fat thickness, conformation, external length, internal length, leg length, rump width, and chest circumference showed linear decreases ( < 0.05) with the inclusion of licuri cake in diets. The inclusion of licuri cake decreased DMI and digestibility, reflecting the lower ADG. Although feed efficiency was not affected, the lambs weighed less at slaughter and the licuri cake had a negative impact on carcass yield. Therefore, the use of the studied levels of licuri cake in diets for finishing lambs cannot be recommended.

Introduction and Objective: Sexual function may be affected in women with urinary incontinence (UI), but data regarding this association are controversial. The aim of this study was to assess the impact of sociodemographic characteristics in the sexual function of Brazilian women with UI., Study Design: Cross-sectional study with 251 women with UI in the period from April to June 2014. Firstly, sociodemographic and pelvic floor dysfunctions (PFD) characteristics were compared between groups of women with and without sexual activity. Secondly, we compared the variables above with the total score of Pelvic Organ Prolapse and/or Urinary Incontinence Sexual Questionnaire (PISQ-12). For continuous variables, we used the Mann-Whitney or Kruskal-Wallis test; for categorical variables we used the chi-square statistic considering the difference of p<0.05., Results: Women with sexual activity tend to be younger, to be premenopausal, have a steady partner and not be hypertensive. The mean total score of PISQ-12 was 27.30. Women who attended elementary school, with coital UI, with moderate constipation and symptomatic prolapse have worse sexual function. Premenopausal women with mixed urinary incontinence have worse sexual function than those with stress urinary incontinence., Conclusion: The association between sexual dysfunction and UI deserves special attention from health professionals. The care of the maintenance or restoration of sexual well-being should be offered to all women, regardless of age, since UI may affect sexual life and QoL of these women., (Copyright © 2016 Elsevier Ireland Ltd.

The objective of this study was to evaluate the effect of concentrate supplementation strategies on the nutritional characteristics of beef cattle in intensive management of tropical pasture. Twenty-four Nellore steer at 250 kg body weight (BW) were used, divided into two plots, with 12 animals in each plot. The experimental area consisted of 32 paddocks with 0.25 ha of Panicum maximum cv. Mombaça. The experiment consisted of 96-day experimental periods, with three periods of 32 days. The strategies studied were P = exclusively on pasture and without concentrate supplementation (control), ES = pasture and supplemented with a concentrate low in protein, PS = pasture and supplemented with high protein content, and PES = pasture and supplementation with balanced protein-energy. There was reduced intake of DM in animals of the treatment P in relation to supplemented pasture, regardless of supplementation. Animals fed on ES showed an intake of more nutrients than the animals on PS. The CP and TDN were also lower in P than in pastures where animals received the additional types of concentrate, and the PS animals showed greater digestibility of CP and TDN than the ES animals. However, the animals exhibited similar weight gains. Animals on P ingested smaller amounts of N and had lower fecal excretion compared to the supplemented animals, but there was no difference between treatments in nitrogen balance. Urea nitrogen and urea from the blood were higher in the supplemented animals than in animals fed on pasture; these levels were also higher in PS animals compared to animals receiving ES. Both the purines absorbed and microbial protein production were similar between treatments. However, the animals fed with concentrate supplementation, independent of the strategy involved, showed higher microbial efficiency compared to animals fed exclusively on pasture.

This study evaluated peanut cake as a replacement for soybean meal in the diet of steers. We used five castrated Holstein × Zebu steers, fistulated, with average live weight 550 kg, in a 5 × 5 Latin square design. The diets were composed of Tifton hay and ground corn with peanut cake (0, 25, 50, 75, and 100 %) as a replacement for soybean meal in the concentrate. Intake (kg/day) of dry matter, neutral detergent fiber, and crude protein were not affected by peanut cake, but ether extract intake increased linearly with the level of peanut cake in the diet. The digestibility of dry matter showed a quadratic effect, with a calculated maximum regression level of 56 % at 37 % replacement. There was no effect of the level of peanut cake on metabolizable energy intake and net energy, ammonia nitrogen, rumen pH, plasma urea, and glucose concentrations. We recommend replacing soybean meal in the concentrate with up to 40 % peanut cake.

Milk and Minas frescal cheese were evaluated from crossbred Holstein × Gir cows that were fed diets enriched with 0, 33, 66 and 100% inclusion levels of palm kernel cake in a concentrated supplement in replace of soybean meal. Eight crossbred lactating cows were distributed (four animals × four treatments × four periods) in the experimental design of double 4 × 4 Latin squares. The capric (C : 10, P = 0.0270), undecylic (C : 11, P = 0.0134), and lauric (C : 12, P = 0.0342) saturated fatty acid concentrations and CLA (C18 : 2c9t11, P = 0.0164) of the milk fat decreased linearly with an increasing percentage of peanut cake in the diet. The increased peanut cake content (100%) in the diet was associated with a linear decrease in C : 10 (P = 0.0447), C : 12 (P = 0.0002), mirystic (C : 14, P 0.05) ratios were not influenced by the different peanut cake levels. The inclusion of up to 100% peanut cake as a substitution for soybean meal in the concentrate of grazing lactating cows resulted in changes in the nutritional quality of their milk products, as indicated by the increase in polyunsaturated fatty acids and the decrease of saturated fatty acids (lauric, myristic, and palmitic).

The aim of this study was to evaluate the effect on intake, apparent digestibility, and ruminal constituents of sheep in response to the addition of increasing levels of babassu mesocarp flour (BMF) to the diet. Twenty crossbred sheep (29.17 ± 2.23 kg) were used in a randomized complete block design. Lambs were confined for 21 days, with 16 days for diet adaptation and 5 days for data collection, in which they were fed an isonitrogenous diet (16.5 ± 0.2 CP, DM basis) containing 70% of concentrate and 30% (DM basis) of Tifton 85 hay. Increasing levels of BMF were 0, 10, 20, and 30% (DM basis). There was a quadratic effect ( P < 0.05) on the DM intake, nutrients intake, and digestibility of CP and NFC. The digestibility of DM, OM, TC, and NDF decreased linearly, while EE digestibility increased linearly with increasing levels of BMF. The high NDF content presented in the chemical composition of the babassu mesocarp flour ranked the same as fibrous food, which can limit the inclusion in the diet of high production animals. So, babassu mesocarp flour is an alternative for energy source in lambs feed and can be added at levels up to 10%., Competing Interests: The authors of this paper have no conflict of interests.

The experiment was conducted to evaluate the ingestive behavior and physiological parameters of confined goats fed peanut cake instead of soybean meal in their feed. We used 40 goats that were ¾ Boer, uncastrated, and 5 months of age on average, with an average initial weight of 15.6 ± 2.7 kg. The treatments consisted of diets with different levels of peanut cake replacing soybean meal in the concentrate (0.0, 33.33, 66.67, and 100%). The experimental design was completely randomized, with four treatments and ten repetitions. For the evaluation of feeding behavior, single animals were observed every 5 min for 24 h on 3 days. The physiological responses (respiratory rate; heart rate; rectal temperature, obtained with a rectal thermometer; and surface temperature) of the animals were evaluated at 09:00 and 15:00 h. The replacement of soybean meal with peanut cake did not change (P > 0.05) feeding behavior. The physiological parameters of the animals (P < 0.05) were altered; however, the changes appeared to be unrelated to the diet and to be due to the weather conditions. Peanut cake can replace soybean meal at 100% without causing negative effects on the feeding behavior or physiological parameters of confined ¾ Boer goats.

The objective of this study was to evaluate the effect of biostimulation and temporary weaning on the follicular dynamics and pregnancy rates in Nelore cows. We used three groups of 75 cows: a control group without biostimulation and suckling calves (WB), a group that was biostimulated and had suckling calves (BE) and a group that was biostimulated and subjected to temporary weaning for 56 h (BETW). Ovarian dynamics were examined using ultrasonography. All groups showed follicular atresia. The interval between beginning of the treatment and wave emergence was 3.25 ± 0.30 days for BE, 3.40 ± 0.27 days for BETW and 3.37 ± 0.50 days for WB. The time between implant removal and ovulation was 64.50 ± 1.88 h for BE, 66.75 ± 1.35 h for BETW and 60.85 ± 3.10 h for WB. Eight cows were submitted to ultrasound analysis, and the percentages of cows that had ovulatory follicles of the new follicular wave with maximum diameters greater than 0.80 cm were 100 % (8/8) in BE (1.28 ± 0.12 cm), 100 % (8/8) in BETW (1.52 ± 0.07 cm) and 87.5 % (7/8) in WB (1.21 ± 0.10 cm). The pregnancy rate was 52 % (39/75) in BE, 69.3 % (52/75) in BETW and 37.3 % (28/75) in WB. The association of biostimulation and temporary weaning increased follicular development, ovulation synchronisation and, consequently, the pregnancy rate in beef cows.

This study aimed to evaluate sunflower cake feed in commercial cut yields and chemical and sensory attributes of goat meat. Thirty-two castrated male goats were distributed in four levels (0, 8, 16 and 24%) of sunflower cake supplementation. The animals were slaughtered and the carcasses were placed in a cold chamber and sectioned into five anatomical regions corresponding to commercial cuts. Samples of the Longissimus lumborum muscle were analyzed for chemical composition and sensory quality. The chemical composition and pH were not affected by the treatments. The smell, taste and 'goatiness' of the aroma and flavor of the meat were also unaffected by the treatments. The appearance, tenderness and juiciness of the meat differed by treatment. The highest level (24%) of sunflower cake increased meat tenderness; however, according to the tasters there was reduced softness, although none of the samples were rejected by the tasters. Sunflower cake can be added to the diet at a level of up to 16% without altering the quantitative and qualitative attributes of the meat., (© 2014 Japanese Society of Animal Science.)

This study aimed to evaluate the intake, digestion, blood parameters, and feeding behavior of crossbred dairy cows (Holstein × Gir) managed on Panicum maximum Jacq. cv. Tanzania-1 and provided supplementation with groundnut cake, sunflower cake, or palm kernel cake (to replace soybean meal). Sixteen cows were randomly assigned in a Latin square design with four treatments and four experimental periods. The consumption of nutrients from the pasture did not vary between experimental treatments. Cows receiving the palm kernel cake supplement had a reduced crude protein, non-fibrous carbohydrate, and total digestible nutrient intake and an increase in the average consumption of ether extract. There was also a reduction in the digestibility of dry matter. The inclusion of supplements in the diet did not influence the average time spent eating, ruminating, or resting. The mean values of respiratory and heart rates showed thermal comfort during the trial period. There was a reduction in blood urea nitrogen with palm kernel cake supplementation, and the values of total protein, albumin, and glucose were also significantly different with this supplement. It is recommended that cakes of groundnut cake and sunflower cake seed be used for a total replacement of soybean meal supplements for lactating cows, but the use of palm kernel cake is not recommended.

Ethnopharmacological Relevance: The goal of this study was to conduct an ethnobotanical survey of medicinal species from the carrasco vegetation of the Araripe National Forest, state of Ceará, Brazil, as well as determining species with bioprospecting potential, Materials and Methods: The ethnobotanical data were collected through semi-structured interviews and a free list. The relative importance of the plants cited was assessed, as well as species that stood out with respect to bodily systems, on the basis of informant consensus., Results: A total of 32 species belonging to 29 genera and 20 families were recorded. Of this total, six species (19%) showed great versatility regarding their uses in regard to up to seven bodily systems. The therapeutic indications were grouped into 14 categories of bodily systems. Circulatory and genitourinary disorders, endocrine, nutritional and metabolic diseases, and undefined pain or disease showed the greatest consensus between informants., Conclusions: Ximenia americana, Himathantus drasticus, Stryphnodndron rotundifolium, Bowdichia virgilioides, and Hymenaea courbaril were the species warranting more in-depth study, on the basis of versatility and informant consensus on the uses of the species., (Copyright © 2014 Elsevier Ireland Ltd.

Introduction and Hypothesis: Little information is available on the recurrent coexistence of pelvic organ prolapse (POP), urinary (UI) and/or anal (AI) incontinence and defecatory dysfunctions and the relationship between these disorders. The purpose of this study is to report the prevalence, bother, and impact on quality of life (QoL) of unreported bowel symptoms in women presenting to a Brazilian tertiary urogynecology clinic., Methods: The study was a cross-section survey of 172 patients with symptoms of pelvic floor disorders (PFD). Patients who reported any defecatory and/or continence disorders were included in the study group, and the others were included in the control group. Patients with UI were also compared with those with double incontinence (DI): AI and UI. Univariate analysis was conducted using the Mann-Whitney U test for continuous nonparametric data., Results: After the interview, 54.6 % (n = 94) of patients presented AI and/or defecatory disorders: 67.0 % constipation, 41.4 % AI, and 34.0 % fecal urgency. Women from the study group scored worse in the QoL questionnaires compared with women from the control group. Among women with UI, 23.21 % had associated AI. Women with DI scored worse in the QoL questionnaires., Conclusion: Anal and urinary dysfunctions are usually associated and have a great impact on a woman's QoL. An integrated approach across specialties should lead to improved patient care. Therefore, our study is relevant because it emphasizes the importance of urogynecologists routinely investigating such symptoms. To do so, standardized questionnaires should be included in the evaluation of all these patients.

The aims of this study were to evaluate the presence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies, to identify associated risk factors and to isolate T. gondii from slaughtered pigs in Paraíba State, Brazil. A total of 190 pigs from public slaughterhouses were used in the study. An indirect immunofluorescence test was used to detect antibodies, and the isolation of T. gondii was performed with a bioassay in mice based on tissues from seropositive animals. A total of 50 g of brain, heart and tongue tissue from 37 positive pigs with titres ≥ 1:64 was ground, digested with acidic pepsin and inoculated into mice. The prevalence of anti-T. gondii antibodies was 19.5% (95% CI: 14.1%; 25.8%) (37/190), with titres ranging from 1:64 to 1:2048. Viable T. gondii parasites were isolated from 13 of the 37 (35.1%; 95% CI: 20.2%; 52.5%) seropositive pigs. We found that the virulence of the isolates varied; three of these isolates were able to kill all of the inoculated mice. The risk factors for infection were extensive husbandry and feeding with leftovers. The prevalence of antibodies to N. caninum in pigs was 3.2% (95% CI: 1.2%; 6.7%) (6/190), with titres ranging from 1:100 to 1:3200. None of the variables studied were considered to be risk factors for N. caninum. These results show that the prevalence of anti-T. gondii antibodies in swine is high in Paraíba State, that the percentage of viable T. gondii parasites recovered from these animals is also high and that infection by this parasite is closely related to the management of swine. Despite the low prevalence of N. caninum in pigs, further studies are necessary to determine the importance of this parasite for the species., (Copyright © 2014 Elsevier B.V. All rights reserved.)

The goal of this bibliographical study was to provide information about residual feed intake (RFI), a new criterion used in the selection of beef cattle for growth rate, food ingestion, and feed efficiency. RFI is calculated as the difference between real consumption and the quantity of food an animal is expected to eat based on its mean live weight and rate of weight gain. In studies of RFI, many speculations are made among researchers about the reliability of this criterion. However, there is a high genetic correlation with characteristics related to post-weaning consumption and maturity, indicating that the biological processes that regulate consumption and efficiency in young animals are similar to the processes that regulate consumption and efficiency in animals of greater age. In contrast to feed conversion, selection based on RFI seems to select for lower rates of consumption and lower animal maintenance requirements without changing adult weight or weight gain. Therefore, we conclude that the data indicate that there are extraordinary benefits to be gained from changing the goals of selection from increased weight gain to improved nutritional efficiency. Given the importance of animal production for economic development in Brazil choosing the best selection goals for livestock improvement is essential. To include an index of feed efficiency in future goals would be desirable, and RFI may play a part in this if economic methods of implementation can be developed.

In the present study, the effect of restricting the feed intake for 77 days and subsequent compensatory growth for 50 days of Sindi females were evaluated. Eighteen animals with an initial age of 21 months and a mean weight of 211.7 kg were placed into three groups according to the following alimentary regimens: feed ad libitum, feed restricted to 20 % dry matter, and feed restricted to 40 % dry matter. In the feed-restriction phase, the nutrient intake decreased (P<0.001) with an increase in the restriction level. As a consequence, the observed decrease in ingestion and serum concentrations of total protein, albumin and globulin, urea, glucose, calcium, and phosphorus were inversely proportional (P<0.001) to the restriction level. Significant differences in the nutrient intake and serum concentration were not observed in the realimentation phase (P<0.05). When animals in the control group reached the end of the feed-restriction phase, their weights (P<0.05) were similar to those in the 20 % restricted group, and both obtained a final weight that was greater than that of animals in the 40 % restricted group. In the feed-restriction phase, the control group had a similar mean daily weight gain (P>0.05) to animals in the 20 % restricted group and (P<0.05) 40 % restricted group. However, in the realimentation phase, the 40 % restricted group obtained greater weight gain rates (P<0.05), better food conversions, and partial compensatory gains. In particular, none of the restricted groups reached the final weight of the control group. In the feed-restriction phase, ingested nitrogen, nitrogen excreted in urine and feces, nitrogen balance and retained nitrogen decreased (P<0.05) with an increase in the restriction level. In the realimentation phase, none of the nitrogen balance variables were influenced by the restriction level (P<0.05). Females in the 40 % restricted group presented better food conversion rates and greater weight gains in the realimentation phase. Based on the animals' compensatory weight gain, a feed-restriction rate of 20 and 40 % can be adopted as a nutritional management practice for prepubescent Sindi females.

Purpose: To determine anatomical and functional pelvic floor measurements performed with three-dimensional (3-D) endovaginal ultrasonography in asymptomatic nulliparous women without dysfunctions detected in previous dynamic 3-D anorectal ultrasonography (echo defecography) and to demonstrate the interobserver reliability of these measurements., Methods: Asymptomatic nulliparous volunteers were submitted to echo defecography to identify dynamic dysfunctions, including anatomical (rectocele, intussusceptions, entero/sigmoidocele and perineal descent) and functional changes (non-relaxation or paradoxical contraction of the puborectalis muscle) in the posterior compartment and assessed with regard to the biometric index of levator hiatus, pubovisceral muscle thickness, urethral length, anorectal angle, anorectal junction position and bladder neck position with the 3-D endovaginal ultrasonography. All measurements were compared at rest and during the Valsalva maneuver, and perineal and bladder neck descent was determined. The level of interobserver agreement was evaluated for all measurements., Results: A total of 34 volunteers were assessed by echo defecography and by 3-D endovaginal ultrasonography. Out of these, 20 subjects met the inclusion criteria. The 14 excluded subjects were found to have posterior dynamic dysfunctions. During the Valsalva maneuver, the hiatal area was significantly larger, the urethra was significantly shorter and the anorectal angle was greater. Measurements at rest and during the Valsalva maneuver differed significantly with regard to anorectal junction and bladder neck position. The mean values for normal perineal descent and bladder neck descent were 0.6 cm and 0.5 cm above the symphysis pubis, respectively. The intraclass correlation coefficient ranged from 0.62-0.93., Conclusions: Functional biometric indexes, normal perineal descent and bladder neck descent values were determined for young asymptomatic nulliparous women with the 3-D endovaginal ultrasonography. The method was found to be reliable to measure pelvic floor structures at rest and during Valsalva, and might therefore be suitable for identifying dysfunctions in symptomatic patients.

The aim of this study was to verify the in vivo effectiveness of pumpkin seed (Curcubita pepo Linnaeus, 1753) in naturally infected ostriches in the Cariri zone, semiarid region of Paraíba State, Brazil. Forty-eight ostriches were used, African Black breed, of 14 to 36 months old, naturally infected by gastrointestinal nematodes. These animals were divided into four groups of 12 ostriches. Group 1 consists of animals treated with 0.5 g/kg live weight (l. w.) of pumpkin seed meal; group 2 received 1 g/kg l. w. of pumpkin seed meal; group 3 was treated with Albendazole 5 %, at the dosage of 1 mL/10 kg l. w.; and Group 4 was the control group and do not received treatment. Groups 1 and 2 received the treatment for three consecutive days, orally, at intervals of 7 days, totaling nine administrations. The Albendazole 5 % was administered one time, at the beginning of the experiment, according to the manufacturer's recommendations. The groups treated with pumpkin seed showed a significant decrease in egg counts per gram of feces (EPG), wherein group 2 (1 g/kg l. w.) was the most effective. The control and drug groups showed no reduction in EPG. The results of the present study demonstrate that the administration of pumpkin seed was effective in controlling gastrointestinal helminths in naturally infected ostriches.

Introduction and Hypothesis: This study assesses the effects of simulated birth trauma, vaginal and cesarean delivery on glycosaminoglycans in the connective tissue of female rat urethra., Methods: One hundred and ten female rats were divided into six groups: A--control, B--vaginal trauma, C--cesarean delivery, D--cesarean delivery followed by vaginal trauma, E--vaginal delivery, and F--female rats on the 20th day of gestation. In each group, half of the animals were sacrificed 4 days after the procedures and half were sacrificed 12 weeks later. Glycosaminoglycans were extracted by proteolysis and analyzed using densitometry after agarose gel electrophoresis., Results: The examination at 4 days showed larger amounts of glycosaminoglycans in pregnant female rats compared to other groups. The examination at 12 weeks showed larger amounts of glycosaminoglycans in the cesarean delivery group followed by simulated birth trauma., Conclusions: There is a change in sulfated glycosaminoglycans in female rat urethra during pregnancy and simulated birth trauma.

Objective: The purpose was to evaluate urine flow rates in an urodynamic study (US) of patients with symptoms of lower urinary tract dysfunction and to record effects of final urodynamic diagnosis and age on these variables., Methods: Retrospective analysis of 205 women who had undergone urogynecological investigation. Patients were divided into three age groups: A (< 45 years); B (45 - 60 years) and C (> 60 years). Comportment of urine flow rates and opening detrusor pressure with increasing age were studied and resulting charts recorded. Comparison of maximum and average urine flow rates, opening detrusor pressure and detrusor pressure at the maximal flow according to final urodynamic diagnostic were also made., Results: There was a decline of urine flow rates with increase of age, which was more significant between groups A X C and B X C. There was also a decline in opening detrusor pressure with aging, which was significant between groups A X C. When analyzing opening detrusor pressure according to final urodynamic diagnosis, a significant decline of this variable was observed in patients with urinary stress incontinence and intrinsic sphincter deficiency in relation to those who were asymptomatic., Conclusion: Urine flow rates decreased with age. Women with urinary stress incontinence and intrinsic sphincter deficiency void at a lower detrusor pressure.

Objectives: The objective was to evaluate the cross-sectional area (CSA) and the Doppler velocimetric parameters of the levator ani muscle vessels in premenopausal women with and without urinary stress incontinence., Study Design: Sixty-three premenopausal women constituted three groups: GI (nulliparous), GII (continent multiparous), and GIII (incontinent multiparous). The patients had undergone transperineal ultrasound in which the CSA was measured and Doppler velocimetry was performed. The examination was repeated by a second observer using the same procedure., Results: There was a statistically significant correlation between the measurements of the observers I and II regarding all the parameters studied, except for the A/B ratio in GIII. The CSA was significantly greater in GI and GII than in GIII. As far as Doppler velocimetry is concerned there were no differences in the Doppler velocimetric indices among the three groups. Concerning the absent end diastolic shift, it was observed that there was a significantly greater incidence of such findings in GI+GII (continent women) towards GIII (incontinent women)., Conclusions: The CSA evaluation and the Doppler velocimetry of the levator ani muscle vessels were highly reproducible. The CSA was higher in continent women and the frequency of the absent end diastolic shift was higher in incontinent women.

The aim of this study was to analyze the amount and types of sulfated glycosaminoglycans (GAGs) of the extracellular matrix (ECM) in the posterior vaginal wall and perineal skin in menacme and postmenopausal women, according to genital prolapse stage. Samples of vaginal tissue and perineal skin were obtained from 40 women who underwent vaginal surgery. Sulfated glycosaminoglycans were extracted by extensive tissue maxatase digestion, submitted to electrophoresis on agarose gel, and their concentrations were determined by densitometry. Dermatan sulphate (DS) was the predominant GAG, followed by chondroitin sulfate (CS) and heparan sulfate (HS). In the vagina there was a significant decrease in total GAGs, CS, DS and HS in postmenopausal women with prolapse stage 2 and 3 compared to the premenopausal group, independent of the stage. In stage 2 and 3 postmenopausal patients there was a significant decrease of DS and HS compared to the stage 1 postmenopausal group. In perineal skin there was no significant difference between total GAG amount, DS and HS. However, the amount of CS in premenopausal stage 1 patients was significantly than that in postmenopausal patients stage 1 and stages 2 and 3. In conclusions, there are quantitative and qualitative differences in GAGs of the ECM in vaginal wall and perineal skin between women in menacme and the postmenopause, according to genital prolapse stage.

This study analyzed the relationship between valsalva leak point pressure (VLPP) and maximal urethral closure pressure (MUCP) in women with stress urinary incontinence. One hundred sixty-one patients were selected with diagnosis of mixed or stress urinary incontinence. During urodynamics we measured VLPP and MUCP. Patients were gathered according to VLPP and analysis of variance (ANOVA) was performed. Pearson's correlation coefficient and linear regression were also utilized. The group with VLPP under 60 cm H(2)O had mean MUCP of 44.5 cm H(2)0; the group with VLPP between 60 and 90 cm H(2)O had mean MUCP of 54.3 cm H(2)O; and the group with VLPP over 90 cm H(2)O had mean MUCP of 60.1 cm H(2)O. We observed correlation between MUCP and VLPP when we used Pearson's correlation coefficient (r=0.22) and linear regression ( p<0.05). There was weak correlation between MUCP and VLPP, and MUCP was significantly lower in patients with leak point pressure inferior to 60 cm H(2)O.

Clostridium difficile produces a potent enterotoxin and cytotoxin, toxins A and B, respectively, which appear to be responsible for pseudomenbranous colitis and antibiotic-associated diarrhea. In the present study we explored the neutrophil migration evoked by toxin A in the peritoneal cavities and subcutaneous air pouches of rats and examined the role of macrophages and their inflammatory mediators in this process. Toxin A causes a significant dose-dependent neutrophil influx into the peritoneal cavity, with a maximal response at 0.1 microg/ml and at 4 h. The depletion of macrophages by peritoneal washing prevents the toxin A-induced neutrophil migration into the peritoneal cavity. In contrast, an increase in macrophages induced by peritoneal injection of thioglycolate amplifies this toxin effect on neutrophil migration. Furthermore, the injection of supernatants from toxin A-stimulated macrophages into the rat peritoneal cavity causes significant neutrophil migration. Pretreatment of rats with BWA4C, nordihydroguaiaretic acid, mepacrine, or dexamethasone inhibits the neutrophil migration evoked by toxin A in the peritoneal cavities. However, pretreatment with the cyclooxygenase inhibitor indomethacin or the platelet-activating factor antagonist BN52021 fails to alter toxin A-induced neutrophil migration. Toxin A was also injected into air pouches of normal rats or rats pretreated with anti-interleukin-1beta (anti-IL-1beta) or anti-tumor necrosis factor alpha (anti-TNF-alpha) antibodies. Anti-TNF-alpha or anti-IL-1beta antibodies significantly reduce the neutrophil migration induced by toxin A. These data suggest that neutrophil migration evoked by toxin A is in part dependent on macrophage-derived cytokines, such as TNF-alpha and IL-1beta, and leukotrienes. These mediators may help to explain the intense inflammatory colitis caused by C. dificile toxin A in an experimental animal model of this disease.
