The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 African Black unsexed ostrich chicks were used in the present study in simple randomized design. The results of the present work indicated that initial and final live body weight, body weight gain, feed consumption, feed conversion of ostrich chicks were insignificantly affected by dietary protein level used. Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP. Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level. Body height and tibiotarsus length were not significantly different. In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%).Keywords: Body measurements, Growth performance, Ostrich, Protein level.

The objective of this work was to evaluate the inclusion of distillers dried grains with solubles (DDGS) as substitution for soybean meal in Hisex Brown laying hen diets with or without enzyme or vitamin E supplementation on productive performance. A total number of 180 Hisex Brown laying hens at 26 weeks of age were randomly divided into 15 treatment groups in a 5 × 3 factorial design experiment, included five levels of DDGS substitution rates for soybean meal (0, 25, 50, 75 and 100%) and three levels of feed additives (without, 250 mg enzyme/kg diet or 200 mg vitamin E/kg diet) through 26-38 weeks of age. The results indicated that increasing DDGS substitution level more than 50% decreased (P≤0.01) averages of feed consumption and feed conversion, egg number and mass. All of these traits gave satisfactory results when hens fed 25 or 50% DDGS substituted by soybean meal. Enzyme or vitamin E supplementation significantly (P≤0.01) decreased both of feed consumption and egg mass. It could be concluded that DDGS was successfully substituted for soybean meal in laying hen diets up to 50% without adverse effects on the performance of laying hens. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The demand for animal products is increasing in developing countries due to population growth. However, livestock production contributes significantly to global warming, accounting for 25%. Probiotics can help improve livestock efficiency by enhancing gut microbes and fat metabolism. They can modify rumen populations, enhance fermentation, reduce methane emissions and improve feed digestion. In this study, the goal was to determine the most effective method of reducing methane emissions in the rumen of sheep in vitro by adding different concentrations of Saccharomyces cerevisiae and Bacillus subtilis., Results: Adding 8 × 10
6 CFU g-1 S. cerevisiae during fermentation reduced pH levels after 48 h. This also increased the concentrations of NH3 -N, microbial protein and total gas production. At the same time, it decreased methane emissions. Furthermore, adding 20 × 106 CFU g-1 B. subtilis to the mixture increased total gas production (TGP) and methane production, with the highest production observed after 48 h. However, it did not affect pH levels after 48 h., Conclusion: It can be concluded that S. cerevisiae had significantly increased microbial protein and NH3 -N concentrations after fermentation without altering pH. Additionally, the addition of S. cerevisiae enhanced TGP and reduced methane emissions. It is worth noting that TGP increased because B. subtilis was added at a concentration of 20 × 106 CFU g-1 , with no significant differences between concentrations. Therefore, we recommend adding S. cerevisiae and B. subtilis to the diet at doses of 8 and 20 × 106 CFU g-1 , as it resulted in higher TGP and reduced methane emissions. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)- Published

- Abstract
One hundred and twenty New Zealand White rabbits (NZW) (5-week-old; 735.27 ± 27.23 g) were kept in an open-sided house during the summer season. The experiment aims to evaluate the impacts of dried tomato pomace powder (DTPP) supplementation on rabbits' performance, blood metabolites, carcass traits, meat quality, and lipid and health indices of NZW rabbits during 5-13 weeks of age. The four treatments were a standard rabbit feed (control) and the control diet supplemented with 0.5, 1.0, and 1.5% DTPP, respectively. Rabbits fed a diet containing 1.5% DTPP showed the highest growth rate through weeks 9-13 of age despite having the lowest feed intake spanning 5-13 weeks. The best feed conversion ratio (FCR) was recorded in rabbits fed with 1.5% DTPP-supplemented diet for 5-13 weeks. Diets supplemented with 0.5 or 1.0% DTPP enhanced markedly dressing %, total edible flesh, saturated (SFAs), monounsaturated (MUFAs), and polyunsaturated fatty acid (PUFAs) contents, as well as the ∑n - 6/∑n - 3 ratio and the total n - 6 of meat. Dietary supplementation with DTPP decreased kidney, abdominal, and back fat. Diets supplemented with DTTP decreased total cholesterol, triglycerides, and very low-density lipoprotein (vLDL) concentrations. The greatest levels of linoleic acid, arachidonic and water-holding capacity in meat were observed in rabbits fed 1.5% DTPP-supplemented diets. Diets containing 1 and 1.5% DTPP improved meats' atherogenic and thrombogenic indices, meat lipid quality desired fatty acids/undesired fatty acids ratio, and meat health index. Conclusively, DTPP up to 1.5% maintained the growth performance of rabbits, boosted meat quality through increasing vitamin E, reduced fat deposition, modified fatty acid composition, and improved atherogenic, thrombogenic, and hypocholesterolemic indices of rabbit meat., (© 2024 Wiley‐VCH GmbH.

- Abstract
The meat of the quail is one of the most delicious types, as it is rich in minerals and vitamins, especially vitamin K, which is useful in treating nervous diseases. In the present investigation, based on their live body weight, 270 genetically-enhanced white quail chicks of mixed sex were randomly assigned to 3 groups, each with 90 chicks. The first group's birds were slaughtered at 28 d of age. The birds in the second group were slaughtered at 31 d, and the birds in the third group were slaughtered at 34 d. Results showed no significant difference between the various groups in the overall mortality rate index at the end of each fattening stage (P > 0.05). There were substantial variations (P ≤ 0.05) in the average live weight index between the first and both groups at each group's marketing age. With increasing marketing age, body weight increases. Quail chicks raised for 34 d received the lowest EPEF (28.90 points), followed by those raised for 31 d and 28 d, which received 33.37 and 37.32 points, respectively. The economic feasibility of the 3 groups, no significant differences in the profit index were observed at the age of 28 d. Compared to the marketing age of the other 2 groups, it was noted that the profit index decreased as the birds advanced in age. Delaying marketing to 31 d leads to a decrease in profit by 5.7%, and delaying marketing to 34 d reduces the profit index to 26.36% compared to marketing at 28 d. For blood hematology parameters, a significant increase in the studied indicators with the age of the birds was observed through the study of blood indicators. Still, it did not reach the significance level. It could be concluded that 28 d is the ideal marketing age for the enhanced white quails, as it yielded the highest economic return and the best performance., (Copyright © 2024 The Authors.

- Abstract
Over the past years, the poultry industry has been assigned to greater production performance but has become highly sensitive to environmental changes. The average world temperature has recently risen and is predicted to continue rising. In open-sided houses, poultry species confront high outside temperatures, which cause heat stress (HS) problems. Cellular responses are vital in poultry, as they may lead to identifying confirmed HS biomarkers. Heat shock proteins (HSP) are highly preserved protein families that play a significant role in cell function and cytoprotection against various stressors, including HS. The optimal response in which the cell survives the HS elevates HSP levels that prevent cellular proteins from damage caused by HS. The HSP have chaperonic action to ensure that stress-denatured proteins are folded, unfolded, and refolded. The HSP70 and HSP90 are the primary HSP in poultry with a defensive function during HS. HSP70 was the optimal biological marker for assessing HS among the HSP studied. The current review attempts to ascertain the value of HSP as a heat stress defense mechanism in poultry., (Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
This study evaluated the effects of dietary supplementation of tomato processing by-product extract (TPBE) on growth performance, carcass characteristics and antioxidant status of growing rabbits under high ambient temperature. A total of eighty weaned New Zealand White (NZW) male rabbits (6-weeks-old; initial body weight, 730.28 ± 36.05 g) were randomly assigned to 4 groups. The first group was the control without supplementation; while the other groups were fed diets supplemented with 100, 200 and 250 mg TPBE/kg. The results showed that TPBE contained 211.85 mg/100g as total phenols and total flavones of 303.36 mg/100g. Rabbits fed a 250 mg TPBE-supplemented diet showed the heaviest body weight, the lowest feed intake and the best feed conversion ratio. TPBE diets reduced mortality percentage. Dietary supplementation of 250 mg TPBE had the highest dressing percentage. Plasma total protein, globulin, catalase and glutathione peroxidase of rabbits fed diets supplemented with 200 and 250 mg TPBE were high. Plasma total cholesterol, triglycerides, plasma hydrogen peroxide and malondialdehyde concentrations were decreased with dietary levels of TPBE. Rabbits fed 250 mg TPBE had higher T-AOC than the other groups. TPBE supplemented diets improved net revenue and economic efficiency. Conclusively, TPBE is containing appreciable content of polyphenols and flavonoids and the dietary supplementation of TPBE (250 mg/kg diet) had a positive impact on growth performance, reducing mortality and enhancing the antioxidant status of rabbits reared under high ambient temperature.

- Abstract
Orange peel and its extract are good sources of phenols and vitamin C that can be used as powerful antioxidants and antibacterial. The effects of dietary ascorbic acid (AA), orange peel powder (OPP) and orange peel extract (OPE) supplementations on growth performance, blood biochemicals, gene expression and antioxidant status of growing rabbits under hot conditions were investigated. A total of 80 weaned Giant Flander male rabbits, five weeks old (606.25 ± 10.08 g), were randomly assigned to four groups. The first group received untreated diet (control group). The other groups received diets supplemented with 0.5 g AA/kg diet, 2% OPP and 500 mg OPE/kg diet. The lowest feed conversion ratio (FCR) was recorded by rabbits consumed diet supplemented with AA. Supplementations of OPP and OPE reduced blood plasma total cholesterol, low density lipoprotein and very-low density lipoprotein concentrations. The tested diets reduced triglycerides, total lipids, hydrogen peroxide, malondialdehyde levels, Staphylococcus aureus and Escherichia coli of the rabbits cecum. Supplementation of OPE improved activities of superoxide dismutase gene (6.1475) and insulin-like growth factor-1 (9.2108). Conclusively, dietary supplementation of OPE improved rabbit performance through improving antioxidant enzyme activities as well as upregulation of insulin-like growth gene. Additionally, OPP and OPE (2% and 500 mg/kg diet, respectively) had antibacterial effects for growing rabbits under hot conditions.

- Abstract
The effects of rearing Cobb500 broiler chickens under 3 different housing systems (floor litter, floor plastic, and batteries) without or with feed additive (Butinov) on broiler performance, blood parameters and carcass traits were evaluated. Three hundred 1-day-old chicks were distributed in a 3 × 2 factorial arrangement (6 treatments each of 5 replicates). The results showed that reared broilers on litter or plastic floors had high values (P ≤ 0.01) of bird's weight (BW), weight gain (WG), and feed intake (FI) throughout the entire study period (1-42 d of age) compared with rearing on batteries. Rearing broilers in the different housing systems and with or without feed additives did not affect (P ≥ 0.05) total feed conversion (FCR). Different rearing systems or feed additives did not influence broiler chicks' carcass traits and some serum blood parameters. The plastic floor system significantly increased (P ≤ 0.05) blood serum corticosterone compared with litter and batteries. Feed additive (Butinov) decreased the level of T
4 (P ≤ 0.05) in blood serum. Plastic floors or batteries significantly increased (P ≤ 0.01) the level of antibody titer against avian influenza virus (HIAV) compared to chicken reared on a litter floor. The results suggested that using housing systems of litter or plastic floors could improve broiler growth performance without adversely affecting carcass traits and blood characteristics compared with rearing in batteries. Also, broiler diets' feed additive (Butinov) and their interaction with rearing systems did not improve broiler growth performance., (Copyright © 2023 The Authors. Published by Elsevier Inc.

- Abstract
The researchers investigated wet feed and chilled water effects on growth performance, carcass characteristics, and physiologic responses of native turkeys during the summer season. We hypothesized that the present treatments during the hot season would show different performances. A total of 180 four-week-old unsexed pullets were divided into six groups in a 3 × 2 factorial arrangement. Pullets were allocated regarding feed conditions to 3 groups ( ad libitum dry feed, ad libitum wet feed, and diurnal wet feed). Each group was divided into 2 subgroups according to water temperature (ordinary or chilled water; 15-16 °C). Pullets fed diurnal wet feed and drank chilled water had the highest daily feed intake and the lowest feed conversion ratio during 4-16 weeks of age. Abdominal fat, IgG level and body temperature were low, whereas total antioxidant capacity and the meat quality scores for color, juiciness, and susceptibility were high in turkeys that drank chilled water. The interaction between wet feed and water temperature showed significant changes in glucose, cholesterol levels, and alanine transaminase activity. Pullets fed diurnal wet feed and drank chilled water had the lowest body temperatures. Wet feeding and chilled water may be the appropriate feeding method for native turkeys raised in hot weather.

- Abstract
This study examined the impacts of dietary spirulina (SP) and canthaxanthin (CX) supplementation to laying hens on reproductive performance and cock's semen quality evaluation. Three hundred and sixty of indigenous Sinai chickens (300 hens + 60 cocks), 48-weeks-old, were randomly divided into five treatments; a control and four supplemented (0.6 g SP mg/kg, 0.8 g SP mg/kg, 6 mg CX/kg diet, and 8 mg CX/kg diet) with six replications of 10 females and 1 male per treatment for laying trial and 1 male for semen evaluation. The animals were fed with experimental diets for 12 weeks. Supplementing 6 mg CX/kg diet led to an increase in the final body weight and egg production traits, while 8 mg CX/kg diet resulted in an improving feed conversion ratio. Supplementation of 0.6 g SP mg/kg or 6.0 mg CX/kg diet resulted in the highest egg production. The heaviest egg weight and egg mass were induced by 0.8 g SP mg/kg. Eggs laid from hens fed 0.6 g SP/kg diet had a higher concentration of cholesterol than those fed 0.8 g SP/kg and those fed 6.0 and 8.0 mg CX/kg. Cocks fed 6 mg CX/kg and those fed 0.8 g SP/kg diet had the greatest sperm concentration. The supplementation of 0.8 g SP mg/kg diet or both 6 and 8 mg CX/kg diet enhanced hatchability. So, dietary spirulina (0.8 mg/kg) and canthaxanthin (6 mg/kg) supplementation to Sinai laying hens and cocks could be used to improve productive and reproductive and performance., (© 2022 Wiley-VCH GmbH.)

- Abstract
Starting phase of laying chicken life is the building stone for rearing and production stages. Since, fecal microbial transplantation (FMT) regulates the gut microbial diversity and affects the productive performance of the bird. The aim of this study is to evaluate the effect of FMT from feed-efficient broiler chicken could program the diversity of gut microbiota and growth of recipient native slow growing egg-laying chicks. For this, a total of 150 (one-day-old) Jing Hong chicks were randomly assigned into two groups, each group consisted of 5 replicates ( n = 15 bird/ replicate). The control group (CON) and FMT recipient birds (FMT) fed on basal diet, the FMT group received an oral daily dose of FMT prepared from Cobb-500 chickens. The FMT performed from the 1d to 28d of age, through the experimental period, feed intake and body weight were recorded weekly. At the end of a 28-day trial, carcass traits were assessed and cecal samples were collected for microbiome assessment via 16S rRNA-based metagenomic analysis to characterize the diversity and functions of microbial communities. The data were statistically analyzed using R software. Body weight and body weight gain increased, and FCR decreased ( p = 0.01) in FMT group. The relative abundance of Firmicutes and the Firmicutes/Bacteroidetes (F/B) ratio were increased due to FMT administration ( p = 0.01). A higher relative abundance of Lactobacillus , Lactococcus , and Bifidobacterium were presented in the FMT group. Meanwhile, Enterococcus , Helicobacter , and Bacteroides were more abundant in the CON group ( p < 0.01). Kyoto encyclopedia of genes and genomes (KEGG) pathways for microbial functions regarding amino acid metabolism, secondary metabolites biosynthesis, carbohydrate metabolism, energy metabolism, and enzyme families, cofactors, and vitamins were significantly annotated in the FMT group. Overall, FMT administration from the donor of highly feed-efficient broilers improved weight gain by reshaping a distinct gut microbiome, which may be related to the metabolism and health in the recipients laying chicks, providing new insight on the application of the FMT technique for early life programming of laying chickens., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Elokil, Chen, Mahrose, Elattrouny, Abouelezz, Ahmad, Liu, Elolimy, Mandouh, Abdelatty and Li.)

- Abstract
The present study examined the effects of fructooligosaccharide (FOS) supplementation in drinking water on the growth performance, carcass characteristics, hematological and biochemical parameters, antioxidant status, and cecal microbiota of New Zealand White (NZW) and APRI rabbits. A total of 180 male NZW and APRI rabbits (aged five weeks; average live body weight 700 ± 39 g) were divided into six groups (30 rabbits/group; 5 replicates/group) in a two × three factorial arrangement. Rabbits of each breed were randomly assigned to one of three treatments of FOS (control; 0.00, FOS-0.5, and FOS-1.0). Results showed that rabbits' final body weight, FBWG, and carcass traits were considerably enhanced compared to those in the control group. The interaction effect of the supplement with the rabbit breed increased the growth, carcass traits, and hematobiochemical and antioxidant parameters with increasing FOS levels. In the cecum of both rabbit breeds, the total bacterial count and Escherichia coli population were considerably low, with a substantial increase in the number of Lactobacilli supplemented by FOS. In conclusion, FOS supplementation enhanced growth and carcass traits by improving the hematobiochemical parameters and antioxidant status and reducing cecal pathogenic bacteria in both breeds.

- Abstract
Effects of exposing quail eggs to high temperature on the heat tolerance ability and productivity of birds were investigated. Four groups of 600 fertile eggs were randomly selected; the first group was incubated under 37.5 °C and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24 °C (Control). The second group was exposed to 39.1 °C for 2 h/day during 4-14 days of embryogenesis and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24 °C. The third group was incubated under 37.5 °C and the hatched chicks were exposed to 39 ± 1 °C for 2 h/day during 4-14 days of age. The fourth group was exposed to 39 ± 1 °C for 2 h during 4-14 days of embryogenesis and the hatched chicks were exposed to 39 ± 1 °C for 2 h/day during 4-14 days of age. The temperature applied changed (P < 0.01) embryo weight and incubation period. Birds exposed to high temperature during brooding had superior growth performance, dressed carcass, body temperature and health traits. Birds subjected to 39 ± 1 °C during brooding exhibited decreased feed consumption and body weight gain. Finally, this work suggests that thermal acclimation during embryogenesis might offer a practical method for easing heat stress., (© 2021.

- Abstract
This work investigated the outcomes of dietary administration of Echinacea purpurea (EP) powder to breeder ducks on productive and reproductive performance during summer season. Sudani ducks (320 birds) of 32-weeks-old (240 females and 80 males) were randomly allocated into four collections (body weight; 1850 ± 15.2 g for females and 2960.0 ± 40.5 g for males). The primary collection consumed the basal diet without supplementation and was deliberated as control. The other three collections were fed the basal diet supplemented with 2.5, 5.00 and 7.5 g EP/kg diet, correspondingly. Egg number and mass, laying rate, feed consumption and feed conversion ratio (FCR) were significantly changed by dietary EP levels. Drakes fed EP-supplemented diets had higher ejaculate volume, sperms concentration and live sperms (%) as well as lower dead sperms (%) than the control group. Eggs laid by ducks fed diet supplemented with 2.5 g/kg had the greatest fertility and hatchability percentages, followed by those fed 5.0 g EP/kg. Ducks fed different EP diets had higher values of haemoglobin, RBCs, WBCs and lymphocytes, lower values of heterophils percentage and lower H/L ratio than the control. All serum constituents were significantly changed by dietary EP supplementation, except of total protein and Alanine Aminotransferase (ALT) enzyme. Conclusively, dietary EP supplementation at 2.5 g/kg had beneficial effects on productive and reproductive performance as well as lipid profile and antioxidant status and economically valued in breeder ducks under summer conditions., (© 2021 Wiley-VCH GmbH.)

The effect of dietary orange peel (OPE) and tomato pomace extract (TPE) supplementations on growth performance, plasma biochemicals, carcass characteristics and antioxidant status of growing male rabbits were investigated. A total of 96 rabbits (5 weeks old) were distributed into four groups. The first group received untreated pelleted diet (control). The second group was fed a diet containing ascorbic acid (AA; 1.0 g/kg diet), while the third and fourth groups consumed diets supplemented with 200 gm of OPE or (TPE, respectively. Our results indicated that OPE and TPE contained 59, 14.03 mg ascorbic acid/100 g DM, respectively. Growth performance, except feed conversion ratio, and carcass weight were improved by dietary supplementations. Dietary supplementations decreased kidneys, abdominal, back fats and ether extract of meat. Plasma protein and globulin levels were high in rabbits fed AA and TPE-supplemented diets. Low plasma total cholesterol and LDL-cholesterol concentrations were observed in rabbits fed the supplemented diets. Plasma AA was increased in rabbits fed AA and OPE-supplemented diets. Rabbits fed OPE and TPE-supplemented diets had great SOD activity. The best economic efficiency was recorded by rabbits fed the supplemented diets. Dietary supplementations of OPE and TPE could effectively improve growth performance, antioxidative status, modulate AA level in plasma and meat and lower plasma total cholesterol and LDL.

- Abstract
Effects of dietary supplemental zinc and/ or selenium enriched spirulina (Zn-Sp, Se-Sp and Zn-Se-Sp, respectively) as antioxidants on growth performance, nutrient digestibility, plasma biochemicals and antioxidant status of growing rabbits under summer conditions were evaluated. A total of 160 New Zealand White male rabbits at six-weeks-old were randomly assigned to four groups. The first group received untreated diet (control). The other groups received diet supplemented with 100 mg Zn-Sp/kg diet, 0.5 mg Se-Sp/kg diet or 100 mg Zn-Sp+ 0.5 mg Se-Sp, respectively. The findings showed that the supplemented diets enhanced growth performance of rabbits at marketing. Rabbits fed Zn-Sp exhibited high dry and organic matter digestibilities while those fed Zn-Sp and Zn-Se-Sp diet supplemented achieved high crude protein digestibility. Rabbits fed diet supplemented with Zn-Se-Sp gave the highest hot carcass weight when competed with their counterparts. Zn-Sp and Zn-Se-Sp supplemented diets tended to promote dressing percentage. Low concentrations of plasma total cholesterol, LDL-cholesterol and VLDL-cholesterol were recorded by Se-Sp and Zn-Se-Sp groups. Rabbits fed Se-Sp, Zn-Se-Sp had the greatest HDL, plasma TAC and catalase and the lowest TBARs. Conclusively, dietary supplementation of 100 mg Zn-Sp, 0.5 mg Se-Sp or their combination could improve growth performance, nutrients digestibility and antioxidant status of heat stressed growing rabbits.

- Abstract
This experiment was conducted to assess nutritional potential of corn steep liquor (CSL) as an alternative protein source in broiler's diet. A total of 280-day-old unsexed broiler chicks were randomly distributed into four experimental groups in a simple randomised experimental design (each group had seven replicates; 10 birds per each). Four iso-nitrogenous and iso-caloric broiler starter and finisher diets (C, LCSL, MCSL and HCSL) were formulated containing 0%, 5%, 10% and 15% CSL respectively. Results revealed that chicks fed MCSL diet had significantly (p ≤ .05) the heaviest Body weight, highest Body weight gain and the lowest feed conversion ratio followed by those fed HCSL diet. In the starter period, LCSL and MCSL diets resulted in better (p ≤ .05) dry matter (DM) (89.57%) and crude protein (67.67%) digestibilities respectively. In the finisher period, DM, crude fibre and fat digestibilities were not affected by CSL inclusion levels; while crude protein digestibility was significantly (p ≤ .05) high in the groups fed LCSL and HCSL diets. The CSL inclusion had no effect on blood haematology except serum uric acid, which tended to increase with increasing CSL levels. No microscopic changes were exhibited on liver, heart, kidneys and intestine of birds across all dietary treatments. However, crops in birds fed HCSL diet showed moderate to severe hypertrophy and hyperplasia of the mucosal lining. The study showed that CSL could be added up to 15% in broiler's diet without any adverse effect on bird's performance., (© 2017 Blackwell Verlag GmbH.)

- Abstract
A study was conducted using 162 Bovans laying hens to investigate the impacts of extra dietary vitamin A (0, 8000, 16,000 IU/kg), selenium (0, 0.25, 0.50 mg/kg), and their combinations on the performance, egg quality, and blood biological parameters of laying hens during summer months. Supplemental vitamin A up to 16,000 IU/kg diet significantly (P < 0.05) improved all productive traits studied except feed intake which increased with 8000 IU/kg diet compared with control. Feed intake and feed conversion of hens fed diet supplemented with selenium revealed high statistical (P = 0.001) differences. All egg quality criteria were not significantly (P < 0.05) affected by dietary vitamin A except albumin percentage and Haugh units, since Haugh unit score was gradually increased with increasing vitamin A level. Vitamin A-enriched groups showed significant (P < 0.05 and 0.01) decreases in plasma albumen, total lipids, and total cholesterol in respect to the unsupplemented groups. Compared with unsupplemented groups, total protein, albumin, total lipid, and total cholesterol were increased in selenium-enriched groups. There were no significant impacts of selenium treatments in layer diets on thyroid hormones and liver enzymes studied except alanine transferase (ALT) and thyroxin (T
4 ), as compared with the control group. Hematological parameters were not affected by vitamin A treatment except PCV% which decreased with vitamin A supplementation. Hemoglobin and lymphocytes were increased with increasing dietary selenium level. In conclusion, the combined supplementary concentrations of vitamin A (16,000 IU/kg) and selenium (0.25 mg/kg) might be needed for better production and health of laying hens reared under heat stress conditions.- Published

- Abstract
The present study was designed to alleviate the negative biohazards of high ambient temperature on the productive performance and physiological status of laying hens. A total of 135 Bovans laying hens were distributed into nine groups in a 3 × 3 factorial design experiment. Basal diet was supplemented with vitamin E at levels of 0, 250, and 500 mg /kg diet. Within each dietary vitamin E level, each diet was supplemented with sodium selenite as a source of selenium (Se) to supply 0, 0.25, and 0.50 mg Se/kg diet. Results showed that supplementing layer's diet with 500 mg vitamin E/kg was accompanied with the lowest feed consumption (FC) and feed conversion ratio (FCR). The interaction among vitamin E and Se levels exerted significant effects only on FC and FCR. Insignificant differences were observed in egg quality criteria due to the treatments studied. Increasing vitamin E level was associated with a gradual decrease in basophil count and an increase in monocytes. A gradual decrease in the count of each of heterophils, monocytes, and eosinophils was observed with the elevation in the dietary Se level. The combination among vitamin E and Se levels produced a significant effect on all hematological parameters studied. As vitamin E increased, a marked decrease in serum AST and a gradual increase in total lipids, total cholesterol, and calcium were observed. As the level of dietary Se increased, serum total protein, albumin, T
4 , total cholesterol, and total lipids increased. No significant impacts were detected for the interaction among vitamin E and Se levels on any of blood constituents determined except serum globulin, ALT, and calcium. In conclusion, the combination between vitamin E and Se showed a good ability to alleviate the harmful impacts of heat stress and produced the highest productive performance when compared with the other groups, which exhibit the synergistic effect between the two antioxidants.- Published

- Abstract
Effects of radiating ostrich eggs before incubation on hatchability, growth performance, and some blood components of ostrich chicks were studied. 72 ostrich eggs were randomly distributed into four groups. The first group was kept without exposure to gamma radiation (control). The 2nd, 3rd, and 4th groups were exposed to 0.8, 1.6, and 3.2 Gy, respectively, of
60 Co gamma rays just before incubation. Total bacterial counts (×103 CFU) were significantly increased with the increase in gamma radiation levels before incubation. Feed conversion was lower (P ≤ 0.01) in the control group than those irradiated. Embryonic mortality rate (%), hatchability (%) and chick weight at hatch, body weight, daily body weight gain, feed consumption, and all of hematology parameters studied were insignificantly fluctuated with the doses of gamma rays used. Serum concentrations of total protein, albumen, globulin, glucose, and triiodothyronin of the chicks from eggs of the control and the 1st group were significantly the highest. Chicks of the control group had significantly the lowest values of serum concentrations of uric acid, creatinine, triglyceride, total cholesterol, ALT, and AST when compared with the other groups. In conclusion, radiation of ostrich eggs before incubation with a dose of 0.8 Gy gamma has a stimulative effect upon the metabolism of hatched chicks.- Published

- Abstract
This review discusses the historical, developmental and practices of ostrich farming in Egypt. In the early 20th century, ostrich farming was very important for production of ostrich feathers and documents were produced to perfect the art of procuring the plumes from the birds and subsequently processing them. Pharaohs used ostrich feathers for adornment. Of 43 provinces, 12 were featured in 2003-2004 as farming ostriches: Alexandria, Al-Behera, Al-Dakahlia, Al-Wadi Al-Gadid, Aswan, Cairo, El-Sharkia, Geiza, Ismailia, Kafr-El-Sheikh, Matrouh and Nubaria. Abattoirs and tanneries specialising in ostrich handling are limited to two. Egypt has numerous strengths and opportunities to develop its ostrich sector. Rising meat prices suggest that fresh ostrich meat is unaffordable to many locals. Funds may be allocated to local advertising campaigns to promote ostrich meat; provision of incentives to farmers; and improving the capacity of abattoirs.
