The present study was carried out to compare the efficiency of different selenium (Se) sources [sodium selenite (SS), Se enriched yeast (Sel-Plex) and Nano-Se] on productive performance, lipid peroxidation, antioxidative status and immunity function of local chickens strain exposed to summer condition (high ambient temperature). One hundred and twenty birds, were randomly divided into 4 treatments: (1) control (basal diet without any supplementation of selenium), (2) SS (basal diet + 0.3 mg Se as SS / kg diet); (3) basal diet + 0.3 mg Nano-Se/ kg diet (Nano-Se); and (4) basal diet + 0.3 mg organic Se/ kg diet (Sel-Plex). The experimental diets are given to birds from 30 to 42 wk of age. Under hyperthermia, dietary 0.3 ppm Sel-Plex or Nano-Se improved feed conversion (g feed/g egg mass), egg production percentage and egg mass (g/d) (P < 0.05). Supplementing diets with Nano-Se increased total protein and globulin content compared with control diet. While, addition different sources of selenium significantly decreased malondialdehyde (MDA) content compared with treat (1) diet. Interestingly, under rise ambient temperature, the inclusion of 0.3 ppm Sel-Plex or Nano-Se in the chikens diet significantly enhanced the antioxidant enzyme (GSH-Px) activity being greater than 2-folds of the controls. Chickens fed diet supplemented with Sel-Plex or Nano-Se showed about 1.5-folds increase in seminal plasma (GSH-Px) compared with control diet. Dietary 0.3 ppm Sel-Plex or Nano-Se had a positive significant effect on Phagocytic activity (PA) and Phagocytic index (PI) on high ambient temperature. In conclusion, dietary 0.3 ppm organic Se or Nano-Se enhanced productive performance, antioxidative properties and immunity in chickens reared under heat stress conditions.

The present study aimed to investigate the effect of administration of selenomethionine, levamisole HCl and selenomethionine plus levamisole HCl to Egyptian buffalo-cows during the late gestation and early lactation period on productive traits (milk yield and composition), reproductive performance, blood metabolites and economical efficiency. Twenty-eight of Egyptian buffalo-cows (2-4 lactation seasons) in the late gestation (two months before calving) were divided into four similar groups (7 buffaloes/each). Buffaloes in the 1<sup>st</sup> group were untreated and served as a control, while those in the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th</sup> were orally treated with 0.9 mg/kg DM twice weekly of selenomethionine (Se-Met), 0.5 mg/kg BW/week, subcutaneously of levamisole HCl (LEV), and 0.9 mg/kg DM orally twice weekly of selenomethionine plus 0.5 mg/kg BW/week, subcutaneously of levamisole HCl (Se-Met + LEV) respectively, during the late gestation and early lactation period (two months before and after calving). The obtained results revealed that the interval from calving to complete fetal membranes drop (FMD) and uterine involution (UI) were significantly (P<0.05) shorter with all treated groups than untreated grou p, being the shortest (P<0.05) and longest (P<0.05) values of interval from calving to FMD and UI were recorded for buffaloes treated with Se-Met+LEV(G4) and untreated buffaloes (G1), respectively. Buffaloes treated with Se-Met+LEV (G4) showed significantly (P<0.05) decrease in the interval from calving to ovarian structure, first estrus postpartum, service period and days open as compared to the control buffaloes (G1) or buffaloes treated with Se-Met (G2) or LEV (G3). The highest (P<0.05) and lowest (P<0.05) values of number of service /conception were observed with the control buffaloes and Se-Met+LEV (G4), respectively. The significantly (P<0.05) reduction of calving interval in all treated groups, especially with Se-Met+LEV. Also, based on cumulative values of conception rate, all buffaloes in Se-Met+LEV and Se-Met groups were conceived with 103 days postpartum, followed by 85.71% in LEV group, while non-buffaloes in control group. Buffaloes treated with Se-Met, LEV and Se-Met+LEV recorded significantly (P<0.05) increase in the actual milk yield as compared to the control buffaloes (9.41, 8.89 and 10.33 vs. 7 kg/day), respectively. Moreover, values of RBC’s, WBC’s , Hb, Ht, Gl, T<sub>4</sub> and T<sub>3</sub> were significantly (P<0.05) increased in all treated groups, while cortisol level was significantly (P<0.05) decreased as compared to the control group. In conclusion, the administration of selenomethionine, levamisole HCl and their combination to Egyptian buffalo-cows during the late gestation and early lactation period exerted a beneficial effect on reproductive performance, milk yield and composition, blood metabolites and economical efficiency. Therefore, it can be recommended to treatment of buffalo-cows with selenomethionine at a level of 0.9 mg/kg of DM/twice weekly, orally and injected subcutaneously with levamisole at a level of 0.5 mg/kg BW/week for improve of the reproductive efficiency, milk yield and economical efficiency.

This study was conducted to investigate the effect of inclusion dried taro waste (DTW) without or with dried yeast (DY) in sheep rations on digestibility, rumen fermentation activity, blood parameters and growth performance of Ossimi lambs. Comparative feeding trial was applied with twenty four growing male lambs, averaging 21.5±2 kg of body weight where they were randomly divided into four similar groups (6 each) for feeding period of 150 days. The experimental rations were formulated as followed: 65% CFM+17.5% rice straw (RS) +17.5% DTW (R1); 65% CFM+17.5% RS+17.5% DTW with dried yeast (R2); 65% CFM+35% DTW (R3) and 65% CFM+35% DTW with dried yeast (R4). Dried yeast (<em>Saccharomyces cerevisiae</em>) was added at the rate of 5g/h/d. Digestibility trials were conducted with Ossimi rams to evaluate the digestibility and feeding values of the experimental rations. Results indicated that most nutrient digestibilities were markedly improved with the higher level of DTW in rations, where R3 and R4 had the highest (P<0.05) digestibility values for most nutrients versus those of the lower DTW ration, without or with DY (R1& R1). Feeding values expressed as TDN did not significantly differ among the experimental rations, while DCP values were significantly improved with increasing the level of DTW, without or with DY. Addition of DY to R2 and R4 rations had no significant effect on feeding values expressed as TDN and DCP. Results of rumen liquor pH values were almost insignificant increased with increasing the proportion of DTW in rations without or with DY. Also, there were no significant differences in NH<sub>3</sub>-N and TVFA´s concentrations among the experimental groups, with the best values being occurred with the low level of DTW-ration with DY additive (R2). No significant differences were observed among experimental groups concerning the all blood parameters except for albumin that was significant higher for animals fed ration contained only DTW with yeast (R4), while the differences respecting this item did not significant among the other treatments. Average daily gain was significantly higher with tested ration R2 than that of R3 or R4, but insignificant higher than that of R1- ration. Daily DM intake was nearly comparable among groups. The best values of feed conversion and economic efficiency were observed with lambs fed ration that contained DTW + RS + DY (R2) while; these items did not improve with increasing DTW level. It could be concluded that DTW is a nutritious fodder ingredient for ration formulation for small ruminant. Therefore the low level of DTW (17.5%) especially with yeast is highly recommended in practical feeding of growing lambs.

Prediction of reproductive status by a simple, non-invasive and applicable procedure is greatly desirable. Saliva sampling is a simple and low-cost process. The purpose of this study was to assess the value of saliva crystallization patterns (SCP) for the prediction of pregnancy in buffalo cows. A total number of 160 saliva samples were collected from twenty buffaloes from Day 0 to 45 post-breeding. The following types of crystallization have been discriminated; none, dotted, branch-like, fir-like, fern-like and mixtures of them. Pregnancy was affirmed ultrasonographically at 25-30 days after breeding. Accordingly, the animals were allotted into pregnant (n=12) and non-pregnant (n=8) groups. Saliva crystallization patterns varied during the post-insemination period between pregnant and non-pregnant animals. The peak incidence of the saliva ferning patterns mainly branch-like pattern at Days 20-25 and 28, and the fern-like pattern at days 15-28 post-breeding could be used as an indicator for pregnant and non-pregnant buffaloes, respectively. In conclusion, SCP is a non-invasive promising diagnostic technique could help to verify early pregnancy at 15-28 days and to reduce the number of the opened buffalo cows.

This study aimed to evaluate dietary supplementation of Moringa oleifera leaves (MOL) on semen quality, oxidative stress, thermal regulation and health status of heat stressed buffalo bulls. Eighteen sexually mature Egyptian buffalo bulls were divided into three groups, 6 in each. Bulls in G1 were fed ration composed of concentrate fed mixture (CFM), berseem hay and rice straw (control). Bulls in G2 and G3 were fed the same CFM supplemented with MOL at levels of 4 and 8% of CFM, respectively for one month pre-semen collection and 4 months as semen collection period. Semen was collected twice weekly and evaluated for percentages of individual motility (IM), livability (SL), abnormality (SA) and damaged acrosome (DA) of sperm cells. Response of spermatozoa to hypo-osmotic test (percentage of curled spermatozoa) at 50 mOsm/l for 30 min was also recorded. Rectal (RT) and skin (ST) temperatures, respiration rate (RR) and pulse rate (PR) were recorded. Blood samples were taken pre-treatment and during 1<sup>st</sup>, 2<sup>nd,</sup> 3<sup>rd</sup> and 4<sup>th</sup> months of semen collection to determine hemoglobin concentration (Hb), packed cell volume (PCV%), count of red (RBCs) and white (WBCs) blood cells. Concentration of total proteins (TP), albumin (AL), globulin (GL), glucose (GLU), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), urea, uric acid, creatinine (Cr) and testosterone, as well activity of AST, ALT, superoxide dismutase (SOD), catalase and glutathione (GSH) were determined in blood serum. Concentration of TG and TC, and activity of AST, ALT, SOD, catalase and GSH were estimated also in seminal plasma. Results showed that RT and ST, RR and PR decreased (P<0.05) in G3 than in G2 and G1. Each of RT and ST, RR and PR increased (P<0.05) up to 3<sup>rd</sup> collection month, then decreased at the 4<sup>th</sup> collection month in association with THI values. Percentage of IM, SL, SA, CT and DA were improved (P<0.05) in G2 and G3 as compared to G1, being the best (P<0.05) in G3. All previous parameters were improved (P<0.05) by advancing collection month. Both TC and TG in seminal plasma decreased (P<0.05) in G3 as compared to G1 and G2. Activity of AST and ALT decreased (P<0.05), while catalase, GSH and SOD activities increased (P<0.05) in seminal plasma of G2 and G3 as compared to G1. Each of TC, ALT, catalase, GSH and SOD in seminal plasma increased (P<0.05), while TG decreased (P<0.05) by advancing collection month, while AST was not affected. Serum testosterone concentration was higher (P<0.05) in G2 and G3 than in G1, being the highest in G3. Each of PCV, Hb and RBCs were higher (P<0.05) in G2 and G3 than in G1, being the highest in G3, while WBCs showed (P<0.05) an opposite trend (P<0.05). Each of Hb, RBCs and WBCs increased (P<0.05) one month after treatment, then Hb and RBC increased (P<0.05), while PCV and WBCs decreased (P<0.05) at the 4<sup>th</sup> collection month. Serum TP, AL and GLU increased (P<0.05) in G3 as compared to G1 and G2, while GL was not affected by treatment. By advancing collection month, concentration of TP, AL, GL and glucose showed gradual increase (P<0.05). Concentration of TG and TC reduced (P<0.05) in G2 and G3, while HDL increased (P<0.05) in G3 as compared to G1. However, LDL was not affected by treatment. Concentration of TG decreased (P<0.05), while HDL increased (P<0.05) by advancing collection month. Concentration of TC and LDL showed fluctuated trend of change at different collection months (P<0.05). Serum urea decreased (P<0.05) in G3, while uric acid, creatinine, AST and ALT decreased (P<0.05) in G2 and G3 as compared to G1. Urea and uric acid decreased (P<0.05) during one month before semen collection and at the 3<sup>rd</sup> collection month, respectively. However, Cr, AST and ALT decreased (P<0.05) by advancing collection month. Catalase, GSH and SOD increased (P<0.05) in G2 and G3, being the highest in G3. All antioxidant enzymes increased (P<0.05) by advancing collection month, being at higher rate for SOD, followed by GSH and the lowest for catalase during month pre-treatment. The current study can conclude that, <em>moringa oleifera</em> leaves could be used as feed additive to help farmers for sustainable development of breeding bulls. Results of this study recommended that daily adding 240 g <em>moringa oleifera</em> leaves per buffalo bull for one month pre-semen collection or at a level of 8% of concentrate feed mixture in diets of buffalo bulls can improve quality and production of semen without any adverse effects on health status under hot climatic conditions in Egypt.

A total number of Two hundred and forty , day old unsexed Pekin and Domyati ducklings (120/each breeds) at one-day old were used in the present study. The experimental period extended for 12 weeks of age. Experimental ducks were randomly divided into four equal treatments (30 Pekin or Domyati ducks each) in three equal replicates (10 ducks each).Ducks were fed diets containing Potassium iodide at levels of 0, 1, 1.5 and 2 mg iodine/kg ration for T1, T2, T3 and T4, respectively.The results showed that growing ducklings fed ration supplemented with Potassium iodide (2, 1.5 and1%) were significantly increased live body weight, body weight gain, feed intake, feed conversion ratio, shank and keel length and body circumference. Relative weight of carcass, and lymphoid organs were significantly increased with iodine. Moreover, blood hemoglobin, red and white blood cells counts and lymphocytes cells% were significantly increased by iodine supplementation to diets . On the other hand, heterophils (%) and H/L ratio were significantly lower by different levels of Potassium iodide supplementation. As well as, plasma total protein, albumin, globulin, A/G ratio, calcium, phosphorus and T<sub>3</sub> were significantly higher in treated than the control groups. Conversely, duckling fed ration supplemented with Potassium iodide recorded a significant decrease in plasma total lipids, cholesterol, triglyceride, AST and ALT concentrations .Conclusively, potassium iodide at 2mg/kg diet level resulted in better performance without any adverse effect on physiological responses and carcass quality traits

This study was designed to evaluate the possibility of using the optimal level of <em>Moringa oleifera</em> leaf aqueous extract (10, 15 or 20%) with 90, 85 or 80% saline (MOLE) as a semen extender of bull semen in comparing with three extenders, including Tris-egg yolk (TEY) without or with vitamin C at a level of 0.9 mg/ml (TEY+VC), and camel skim milk (CSM). Semen was collected from five Friesian bulls (350-450 kg LBW and 3-4 years old), twice a week for 5 weeks using artificial vagina. After ejaculation, mass motility was evaluated and only those of ≥70% were used in this study. Ejaculates were pooled, divided into 4 replicates and prepared for freezing. Semen was extended in TEY (control), TEY+VC, (CSM) and 15% MOE+85% saline (based on the best results of MOLE level). Semen was diluted, equilibrated at 5<sup>o</sup>C (4 h) and placed in liquid nitrogen (LN) at -196<sup>o</sup>C. Frozen semen stored for one month at least was warmed at 37<sup>o</sup>C for 30 sec. Semen evaluation for percentages of individual motility (IM), live sperm (LS), sperm abnormality (SA), acrosomal damage (AD) and hypo-osmotic swelling test (sperm cells with curled tail, CT) was estimated in diluted, equilibrated and thawed semen, while percentage of head to head agglutination (HHA) was determined in post-thawed semen only. Activity of AST, ALT, LDH and total antioxidant activity were determined in seminal plasma of post-thawed semen. Conception rate (CR) was recorded for Friesian cows inseminated with semen frozen with the four types of extenders. Results showed that percentages of IM, LS, SA, AD and CT in post-diluted and post-equilibrated semen, beside all previous characteristics and percentage of HHA in post-thawed semen showed the best results (P<0.05) in CSM, moderate in 15% MOE and TEY+VC, and the poorest in TEY. Enzyme activities of AST, ALT and LDH in post-thawed seminal plasma were the lowest (P<0.05) in CSM, followed by 15% MOE, while total antioxidants activity was higher (P<0.05) for TEY+VC, CSM and 15% MOE than for TEY, being the highest for 15% MOE. Artificial insemination of estrous synchronized cows with semen extended by different types of extenders indicated that conception rate of cows was significantly (P<0.05) the highest for Friesian cows inseminated with post-thawed semen extended with CSM (87.5%), moderate with both TEY+VC and 15% MOE (75%) and the lowest with TEY(62.5%). Extender containing 15% MOE showed the cheapest cost (4.80 L.E./100 ml) in comparing with CSM (6.45 L.E./100 ml), TEY+VC (13.95 L.E./100 ml), and even the conventional TEY extender (13.85 L.E./100 ml). In conclusion, extender containing 15% <em>Moringa oleifera</em> leaf extract and 85% saline solution could be successfully used, as a source of antibiotics and antioxidants, in extenders of frozen bull semen, being with the cheapest cost as compared to tris-egg yolk or camel skim milk extenders.

This study was conducted to elucidate the effect of two types of antioxidants containing compounds on some physiological components of laying hens for 8 weeks as well as egg quality with special reference to egg yolk cholesterol concentration. Ninety six adult Shaver White laying hens were randomly divided into six groups ,each contained sixteen birds , control group, two garlic groups ( fed on basal diet plus 1g or 3g/kg), two yeast groups (fed on basal diet plus 2g or 4g /kg), and the last group received basal diet plus a mixture of 3g garlic and 4g yeast /kg. Feed intake significantly increased in groups received garlic (3g/kg) and that received garlic and yeast together, while egg weight , Haugh unit and egg mass, were not significantly affected but egg production percent significantly improved . Egg yolk cholesterol significantly declined in all treated groups, especially in that given both garlic and yeast. serum total lipids, triglycerides, cholesterol as well as LDL-C significantly declined in most treated groups while serum HDL-C significantly increased in the groups receiving garlic (3g/kg) or both garlic and yeast. Also serum total protein and albumin levels increased in the group supplemented with both garlic and yeast. Serum levels of estrogen and progesterone significantly increased in the group receiving both garlic and yeast. In conclusion dietary garlic and yeast powder can be used for laying hens to increase egg quality , since, they have a cholesterol-lowering effect.

An experiment was conducted to study the differences in liver metabolism of some chicken breeds had different levels of domestication and production types. Hepatic oxygen consumption (HOC), liver weight percentage, liver glycogen, liver fat and Plasma lipids profiles of 180 birds of Dandarawi (D), Lohmann selected leghorn (L.S.L) and Cobb<sup>500</sup> chicks were assayed. The experiment was terminated at 8 weeks of age. Breed had significant effect on hepatic oxygen consumption, liver weight percentage, liver glycogen, total cholesterol and high-density lipoprotein (HDL). The Dandarawi had significantly (P≤0.05) higher HOC and liver glycogen compared to L.S.L and Cobb<sup>500</sup> chicks. Meanwhile, the Cobb<sup>500 </sup>chicks had significantly (P≤0.05) lower liver weight percentage and had significantly (P≤0.05) higher total cholesterol and HDL compared to D and L.S.L chicks. The effect of sex was also noticed in liver weight percentage, the female had significantly (P≤0.05) higher liver weight when compared to male chicks. The effect of interactions between breed and sex was also noticed in liver fat, the male Cobb<sup>500</sup> had significantly (P≤0.05) higher liver fat when compared to female Cobb<sup>500</sup>, male and female D and L.S.L. chicks. It can be concluded that domestication and intensive selection for growth rate and egg production has resulted in alterations in hepatic metabolism, liver glycogen, and, fat and plasma lipids profiles.
