This study was carried out to evaluate the impact of dietary supplementation of probiotic (Diamond XP™<strong>)</strong> T1 or prebiotic (BioBoost<sup>TM</sup>) T2 on nutrient digestibility, rumen fermentation characteristics, productive performance and economic efficiency of Barki lambs. Lambs in control group offered a concentrate feed mixture (CFM) and clover hay without supplementation while, lambs in treatment (T1) and treatment (T2) were fed CFM supplemented with probiotic or prebiotic at rate of 10 g/ head/ day, respectively. Nine barki male sheep (47kg ± 2.5) were used for running metabolism trail. The animals were allocated into three equal groups. Three ruminally cannulated ewes (45 kg ± 3.2) were used to study the rumen liquor parameter, while growth performance trails were carried out with twenty four growing male Barki lambs (27.5 kg ± 0.75) used to determine the growth performance, feed conversion and economic efficiency.The obtained results could be summarized as follow: Animals given ration supplemented with probiotic recorded the highest values of (p<0.05) digestibility and nitrogen utilization followed by animals given ration supplemented with prebiotic, however those fed control ration had the lowest values. The same trend was observed with TDN and DCP values.No significant (p<0.05) differences among rations in ruminal pH values, were recorded while total volatile fatty acids (VFA’s) concentration and microbial protein synthesis had significantly (p<0.05) increased with probiotic supplement. The control ration recorded the highest ruminal NH3-N concentration. A positive impact of probiotics (DFM) and prebiotic supplementation on nutrient intake, feed conversion ratio and economic efficiency have been recorded. It could be concluded that feeding lambs on rations supplemented with either probiotic (DFM) or prebiotic at 10 g/h/d has beneficial effects on rumen parameters, digestibility coefficients, growth performance and economic efficiency of growing Barki lambs.

This investigation aimed to determine the seasonal variations of zinc and copper concentrations in Egyptian Baladi goat milk, in relation to some reproductive characteristics under environmental conditions of Aswan governorate. Zinc and copper concentrations in Baladi goat's milk were determined using atomic absorption (AA) flame spectrometry techniques. The study was carried out on 32 pregnant Baladi goats that reared under the environmental conditions of Aswan governorate. According to season of kidding, goats were divided randomly into two comparable groups. Goats in the first group kidded in cool season and in the second one kidded in warm season. Results showed that higher concentrations (P <0.05) of zinc and copper were found in Baladi goat's milk during cool months and warm months (0.77± 0.324 and 0.65 ± 0.012 <em>vs</em>. 0.48 ± 0.113 and 0.23 ± 0.011 mg/l) respectively. Kidding and twinning rates were insignificantly higher in Baladi goats kidded during the cool season (151.7 and 68.2%) than the warm season (144.4 and 61.5%). Rates of stillbirth, abortion and retained placenta were insignificantly higher in Baladi goats kidded during the warm season (15.4, 15.6 and 18.5%) compared with (11.4, 9.4 and 17.2<strong>%</strong>) in cool season, respectively. There is a positive correlation between copper concentrations in Baladi goats milk and both kidding and twining rates. Similar trend, showed between zinc concentrations and kidding rate (r= 0.589<sup>,</sup> 0.577 and 0.614), respectively. There was negative correlation between zinc and copper concentrations in Baladi goat's milk and stillbirth, abortion rates. Similar trend, showed with retained placenta rate. The study observed that the seasonal changes in concentrations of zinc and copper in Baladi goat's milk related strongly with reproductive process of goats. The reproductive phenomena of Baladi goats during the cool season was better than that during the warm season. Supplementation of zinc and copper to diets of Baladi goats during the warm season improve the reproductive characteristics.

The aim of the present study was to define the effect of different extender components (as conventional and non-conventional extenders) on rams' semen quality during storage at 5ºC for up to 6 days. Fertility rates of the extended ram spermatozoa stored at 5ºC for up one day were also studied. Four Rahmani rams were used to collect pooled ejaculates by artificial vagina. Semen was collected, evaluated and extended with five extenders included conventional and non- conventional extender ingredients. The conventional extenders were sodium citrate (E1), Tris (E2) and skimmed milk powder (E3) - based glucose- egg yolk. While, non-conventional extenders were salt of sodium chloride 0.9% (E4) and saline solution 0.9% intravenous infusion (E5) based glucose-egg yolk. The final extension rate was 1semen : 6 extender. The extended semen with different extenders media (E1, E2, E3, E4 and E5) were cooled to 5ºC and stored at this temperature for 6 days. After storage time (0, 1, 2, 3, 4, 5 and 6 days), the percentage of sperm motility (SPM), recovery sperm motility (RSM) and positive osmotic resistant (POR) were recorded. Also, fertility rate was carried out with liquid semen stored at 5ºC for up to one day using the best conventional and non-conventional extenders. Thus, twenty-two ewes were used to investigate fertility rate. Ewes were divided into two groups (11/group), the1<sup>st</sup> and 2<sup>nd</sup> groups were artificially inseminated with conventional (E2) or non-conventional (E5) extenders which obtained better semen quality than other extenders, respectively. The results indicated that, the cooling extended ram semen with each of E1, E2 or E5 extenders was significantly (P<0.05) higher the percentage of SPM, RSM and POR than those extended with E3 and E4 extenders during storage at 5ºC for up to 6 days. However, the cooling ram semen with E2 and E5 showed non-significantly parameters during cooled at 5ºC till 6 days. The statistical analysis of the data revealed a significant positive correlation between extender types and SPM, RSM and POR of ram spermatozoa during storage at 5ºC until 6 days. Surprisingly, fertility rate of ewes artificially inseminated with ram semen preserved at 5ºC for one day of storage performed to assess higher conception rate (84.62%) with E5 ( as non-conventional extender) than conception rate (78.57%) with E2 (as conventional extender). Moreover, the superior litter size recorded 1.00 with ram semen extended with E5 compared to 0.86 with E2 extenders. Also, sex ratio of born lambs displayed female lambs 66.67 and 33.33% of male lambs with semen extended with E2 extender. Ram semen extended with E5 achieved female lambs 69.23% and male lambs 30.77%. It is therefore concluded that saline solution (0.9%) intravenous infusion (E5) based glucose-egg yolk intended to keep goodness fertility rate and litter size after AI of cooled semen at 5ºC.

The objective of this study was to investigate the effect of using some sources of antioxidants on the productive and reproductive performance of turkeys. This study was carried out at Mehalet Mousa Animal Production Research Station, Kafr El-Sheikh, belonging to the Animal Production Research Institute, AgriculturalResearchCenter, Ministry of Agriculture, Egypt. A total of 84 Bronze female turkeys, 32 weeks of age were used. The birds were randomly distributed into 7 experimental groups; each consisted of three equal replicates. The birds were individually housed in battery cages. The experimental period lasted 12 weeks (from 32 to 44 weeks of age). The birds were fed a yellow corn-soybean meal-based diet, supplemented with two antioxidants, zinc and selenium of three sources organic, inorganic and nano forms. The experimental groups were fed one of the following diets: (1) a basal diet without added zinc or selenium; (2) inorganic zinc (zinc oxide) 100 mg/kg diet; (3) organic zinc (zincmethionine) 100 mg/kg diet; (4) nano zinc (zinc oxide nanoparticles) 40 mg/kg diet; (5) inorganic selenium (sodium selenite) 0.3 mg/kg diet; (6) organic selenium (selenomethionine) 0.3 mg/kg diet; (7) nano selenium (selenium nano-particles) 0.15 mg/kg diet. The results obtained can be summarized as follows. Dietary supplementation with inorganic, organic and nano forms of zinc and selenium significantly (P≤0.05) increased serum levels of total protein, concentrations of blood haemoglobin, egg fertility, hatchability of eggs in turkey hens, and significantly (P≤0.05) improved feed conversion ratio as compared to that of the controls. Dietary supplementation with inorganic, organic and nano forms of zinc and selenium significantly (P≤0.05) decreased feed consumption, serum levels of total lipids and cholesterol as compared to those of the controls. Supplementation of organic and nano forms of zinc and addition of inorganic, organic and nano forms of selenium to diets of laying turkey hens significantly (P≤0.05) increased hen-day egg production rate and egg weight as compared to those of the controls. Dietary organic and nano forms of zinc and selenium of turkey hens caused significant increases (P≤0.05) in serum antibody titres against Newcastle disease virus and improved immunity, and exhibited a significant increase in relative weight of spleen and oviduct length compared with their control group. Turkey hens fed diets supplemented with organic and nano Se produced eggs with better albumen quality and egg shell quality as measured by Haugh units and egg shell thickness as compared to that of the control turkey hens. There were no significant differences among the different dietary treatments in relative weights of egg components, egg shape index, egg yolk index, yolk color score, relative weights of carcass yield, liver and heart of turkey hens. It can be concluded that dietary supplementation with organic and nano forms of zinc and selenium can induce beneficial effects on productive and reproductive performance of turkey hens.
