This experiment was conducted to evaluate the effects of changing feed form in commercial laying pullets at their 9-14 weeks of age. In the first eight weeks of rearing, the birds were fed four basal diets, including two feed forms (mash;M vs. pellet;P) and two levels of sunflower hulls (SH) inclusion (0 vs. 4%); then, they were assigned to 11 treatments with eight replicates of 9 birds each. The experimental groups consisted of the mash diet during 0-8 and 9-14 weeks (control); mash from 0-8 week and pellet +SH from 9-14 weeks (M-PSH); and so on MSH-MSH; MSH-PSH; P-P; P-M; P-MSH; P-PSH; PSH-PSH; PSH-MSH; and M-MSH. During the whole period, average daily feed intake (ADFI) in the birds fed with pellet or mash and then fed with the pellet containing SH (P-PSH and M-PSH) was higher than with the other treatments (P < 0.05). Average daily weight gain (ADG) was affected by dietary fiber and feed form, whereas it was found lower in the PSH–MSH treatment birds and greater for the birds in MSH-PSH treatment than others (P < 0.05). Further, FCR improved in the birds fed the mash diet with and without fiber from during 1-14 weeks (P < 0.05). Feeding pellet diet without fiber during 1-14 weeks resulted in lower gizzard weight and deeper crypt than the other groups (P < 0.05). In addition, the greater and lower villus surface area belonged to the birds fed MSH-MSHP-P diets during 1-14 weeks, respectively. The greatest tibiotarsal index was related to the group fed the pellet or mash without fiber during 0-14 weeks (P < 0.05). In conclusion, considering the costs for pellet production, it seems that feeding pellets just during the first eight weeks of age could lead to better performance in commercial situations. Moreover, dietary inclusion of SH improved the function of gizzard.

Objective This study was conducted to evaluate the effects of feed processing and particle size on growth performance, nutrient digestibility, carcass characteristics, and gastric health in growing-finishing pigs. Methods A total of 360 growing pigs (22.64±0.014 kg initial body weight [BW]) were allocated to 1 of 6 treatments with 6 replicates by BW and sex, and 10 pigs were housed in one pen in a randomized complete block design. The BW and feed intake were recorded to calculate growth performance. For the digestibility trial, a total of 24 barrows with an initial BW of 33.65±0.372 kg were split into 6 treatments with a completely randomized design. Dietary treatments were designed by a 2×3 factorial arrangement of treatments based on two main factors, particle size (600, 750, 900 μm) and feed form (mash and pellet) of diet. Experimental diets were formulated to contain the requirements of the NRC (2012). Results The BW and average daily gain were not changed by dietary treatments, and the feed intake of finishing pigs (wks 6 to 12) was increased when the pigs were fed a mash diet (p

Texture is one of the key quality attributes used in the fresh and processed fish industry to assess product quality and consumer acceptability. To improve the textural quality of tilapia, we formulated the expanded pellet diet (EPD) and pellet diet (PD), both containing faba bean (Vicia faba, FB) water extract, a previously reported potential aquafeed additive to increase flesh texture. The common diet was used as a control. After Nile tilapia (Oreochromis niloticus) were fed three kinds of experimental diet for 120 days, muscle textural quality, growth parameters, oxidative response and immune parameters were analyzed. The results showed that there was no significant difference in the growth parameters between the three groups (P >0:05). The highest measure of textural quality (hardness and chewiness) was found for the PD group, followed by the EPD and the control (P <0:05). Less oxidative damage to the hepatopancreas and intestine was found in the EPD compared with the PD group, as demonstrated by the decreased levels of reactive oxygen species and increased levels of nicotinamide adenine dinucleotide and intestinal digestive enzyme activity (amylase and lipase). Taken together, this study highlights the potential usefulness in commercial settings of FB water extract for improving the textural quality of tilapia, and EPD containing faba bean water extract could be more advanced substitute for faba bean in tilapia culture in term of both effectiveness in textural quality improvement and health status enhancement compared with PD.

BACKGROUND: The liver and heart are two main damaged organs in ascites syndrome in fast -growing broilers. Using silymarin with a protective effect on the liver and heart may be a beneficial strategy to decrease ascites-induced mortality. OBJECTIVES: The present study assessed the cardiohepatic effects of silymarin in broilers fed on mash and pellet diets by assessing electrocardiographic (ECG) indices and some serum biochemical parameters. METHODS: A total of 120 Arbor Acres chicks were allocated to 6 groups and treated as follows: basal mash diet (CM); basal pellet diet (CP); silymarin at 500 ppm of mash (M500) and pellet diets (P500); and silymarin at 2500 ppm of mash (M2500) and pellet diets (P2500). RESULTS: CP had higher serum activities of aspartate aminotransferase, alanine aminotransferase, and creatine kinase MB (CK-MB) enzymes compared to CM (p

An experiment investigated performance of birds fed the pelleted corn-soy diet versus the pelleted 30% copra meal based diet with different pellet sizes. This study was conducted for six weeks. A total of 144 male day old chicks were used in this trial. One day old birds were randomly allocated to four treatment diets with six replications. The starter and grower pelleted diets were with or without 30% copra meal and in two forms, either fine or mixed sized particles. The experimental design was a two way factorial with two basal diets, two particle sizes and six replicate cages of six birds per treatment. The inclusion of 30% copra meal in the pelleted diet decreased body weight and feed intake, but improved feed eficiency. Grinding the diet to a fine pellet size impaired the body weight and feed intake. The effect of pellet size became more evident when the birds grew older. Birds fed the pelleted form of copra meal accelerated their growth rate so that they were not significantly different from the weight of birds fed the pelleted form of the corn-soy diet. However the feed intake of birds fed the pelleted copra meal diet was lower than the feed intake of those fed the pelleted corn soy diets. It was concluded that inclusion of copra meal in the diet impaired growth of birds, particularly in the starter phase. Pelleting and crumbling copra meal diet could increase the bird performance to the same level of the performance of birds fed the pelleted corn-soy control diet while fine grinding the pelleted diet reversed this trend.

A total of 780 unsexed day old Arbor Acres chicks were used. The birds were randomly distributed into 26 treatments of 30 chicks each. Two studies were designed to compare three phytase sources differed in their microbial origin and thermo-stability on performance and bone mineralization of broilers. In Exp. 1, with less 40% available phosphorus (aP) diets than recommendation, chicks were fed 0.3% and 0.27% aP (-40% aP), during starter and grower periods, respectively, and supplemented with one of the following phytases; Phytase I (Schizosaccharomyces pombe), Phytase II (Trichoderma reesei) and Phytase III (Pichia pastoris) at 3 levels (0, 500 or 750 FTU/kg diet) each within two feed forms (mash or pellet) in 3×3×2 factorial design. In a concurrent study, with less 20 or 40% aP with the most stable phytase source from Exp. 1 at 0, 500 and 750 FTU/kg diet, also in mash or pellet feeds (Exp. 2) in 2×3×2 factorial arrangement. In both experiments, two control groups fed strain recommendation of aP (contained 0.5%, 0.45% aP during starter and grower periods, respectively) with the same feed forms were used for comparison. Results obtained indicate that: Experiment 1: There is a difference in thermo-stability among phytase sources according to the microbial origin. 1- Chicks fed -40% aP and supplemented with either Phytase I or Phytase III had significantly higher weight gain and carcass percentage than Phytase II. 2- Chicks fed pellet diets recor ded (P≤0.05) better growth performance compared to those on mash diets. It could be concluded that: phytase I (Schizosaccharomyces pombe ) is the most stable phytase, while, chicks fed -40% aP, irrespective of phytase source didn't reach the values of control group (strain recommendation of aP) concerning growth performance parameters or bone measurements. Experiment 2: Chicks fed -20% aP diet improved feed conversion ratio (FCR) by 4.1% for overall period and higher plasma P and Ca by 34.8% and 27.7%, respectively comparing to others fed -40% aP. 1- Chicks fed dietary Phytase I at levels of 500 and 750 FTU/kg diet improved significantly live body weight, carcass % and better overall FCR. 2- By feeding pellet diet, chicks recorded better overall FCR by 4.1% than those fed mash diet. It could be recommended that addition of coated Phytase I (Schizosaccharomyces pombe) at 500 FTU/kg diet to -20% aP diet improved growth, bone mineralization of broiler chicks fed either mash or pellet diets.

Abstract: Chronic diarrhea could be a challenge from both the diagnostic and therapeutic point of view. This case report will discuss the clinical approach to the evaluation of chronic diarrhea with the production of free fecal water in an adult horse. The discussion of this case report may provide further information and describe a possible therapeutic option with sulfasalzine, focusing on the nutritional management of chronic diarrhea in adult horses. Nutritional management could be of higher importance for horses that suffer from this problem because it improves the well-being of the hindgut environment. In the present case report, motility abnormalities were identified without other physiological disturbances of colonic function or a decrease in body weight, and the priority was the following: (1) rebalancing of the diet to the real nutritional requirements of the patient, (2) avoiding excess carbohydrate from both forage and concentrate, (3) selecting the right proportion between good quality first-cut meadow hay and grounded and pelleted meadow hay that helps to reduce mechanical and physical load of the colon and could help in the formation of more homogeneous digesta, (4) reducing the stress with adequate feed consumption time, meal size, and time spent in a overgrazed paddock, and (5) increasing the proportion of omega-3 fatty acids in the diet. With the nutritional plan and management and the initial use of sulfasalazine, the horse maintained a good quality of the feces with a reduced or absent production of the free fecal water.

Inclusion of the water-soluble fraction of blue mussels Mytilus galloprovincialis as a feed additive was examined with tiger puffer Takifugu rupbripes. The control diet mainly consisted of fish meal, potato starch, and pollack liver oil. Experimental diets were formulated to replace 30% and 40% of the fish meal protein with defatted soybean meal (SBM), and were supplemented with 0–20% mussel extracts. Fish of 18 g initial body weight were fed each diet to satiation, twice daily, 6 days per week for 7 weeks at 20°C. Weight gain and protein efficiency ratio of fish fed the diet containing SBM without the extract were significantly lower than those of the control at the 30% replacement level. Addition of 5% or 10% extract improved the growth and feed utilization to levels comparable to those of the control. At 40% substitution, statistically identical growth and feed performance to the control were obtained for diets supplemented with 10% or 20% extract; however, performance for 5% addition was significantly lower. Thus, the water-soluble fraction of blue mussels would be an effective feeding stimulant in aquaculture feed for tiger puffer that makes it possible to replace 30–40% of fish meal protein with SBM.

Dietary treatments were designed by a 2×3 factorial arrangement of treatments based on two main factors, particle size (600, 750, 900 μm) and feed form (mash and pellet) of diet. Experimental diets were formulated to contain the requirements of the NRC (2012)., Results: The BW and average daily gain were not changed by dietary treatments, and the feed intake of finishing pigs (wks 6 to 12) was increased when the pigs were fed a mash diet (p<0.05). For the overall period, the feed efficiency of pigs was improved with the pellet diet (p<0.01) and reduced particle size (p<0.05). The pellet diet had effects on increasing crude fat digestibility (p<0.01) relative to a mash diet, but there was no considerable change in dry matter and crude protein digestibilities by dietary treatments. In the evaluation of gastric health, a trend for an increased incidence of keratinization in the esophageal region was observed as particle size decreased (p = 0.07)., Conclusion: Feed efficiency could be improved by pellet diet and reduced particle size. Nutrient digestibility, carcass characteristics, and gastric health were not affected by feed form, and particle size ranged from 600 to 900 μm.
