The aimof this study was to assess the effect of in ovo injection with saline, vitamins (D 3 and B 12 ) and zinc and L-carnitine on the hatching rate and blood constituents in newly hatched chicks. A total of 1170 eggs from broiler breeders were divided into sixtreatmentgroupsof eggs:a control group without injectionwhich served as sham-operatedor a negative control group and five groups were injected with saline, vitamin D 3 , zinc, vitamin B 12 or L-carnitine, respectively. All eggs were set at a temperaturerange between 24-26°C for 6 hours before exposure to the incubation temperature. Then the injection process occurred at the 18 th day and 12 hours of the embryonicdevelopment by depositing the test materials into the air sac at the wide end of the eggs, then the hole was closed with wax. The highest value of fertile hatchability was recorded in eggs injected with vitamin D 3 and zinc, respectively, followed by vitamin B 12 and L-carnitine. The injected test materials (vitamin D 3 , zinc, vitamin B 12 and L-carnitine) had a positive effect on the percentage of late dead embryos compared to negative control group. All injected materials except zinc led to an increase in plasma levels of cholesterol and low-density lipoprotein but levels of glucose, triglyceride, high-density lipoprotein, total protein, albumin and globulin were not affected. In conclusion, in ovo injection of vitamins (D 3 and B 12 ), zincand L-carnitine may be suggested as an effective technique for increasing hatchabilityand profitability in aged broiler breeders

One-day-old Japanese quail birds totaling 900 were divided into five groups, with six replicates in each group. Five doses of DL-methionine supplementation were used in a one-way arrangement for the experimental treatments. At concentrations of 0.0, 0.9, 1.65, 2.15, and 2.65 g/kg feed, DL-methionine was included in a basal diet. Dietary methionine values ranged from 0.41 (inadequate), to 0.50 (sufficient; 100% NRC), to 0.58, 0.63, and 0.68 (excess), compared to the current NRC standards. Dietary methionine levels did not significantly affect performance at 32 days of life. DL-methionine has no significant effect on total protein, albumin, globulin, creatinine, uric acid, total antioxidant capacity (TAC), or malondialdehyde (MDA). In contrast, serum high-density lipoprotein (HDL-c) levels significantly increased (P ≤ 0.05) in response to DL-methionine supplementation, and serum immunoglobulin G (IgG) levels significantly varied between groups (P ≤ 0.05) in response to DL-methionine supplementation, with the highest level occurring at 0.68% (exceeding) the NRC (1994) recommended concentration. Our findings imply that production performance, immunity, or antioxidant status can be improved by dietary supplementation with DL-methionine levels at 0.68% (excess) of the NRC (1994) recommended levels. However, a high methionine intake has a beneficial impact on enhancing serum HDL levels.

Egyptian local sheep breeds are widely spread over the country; raised mainly by smallholders and contribute significantly to their livelihood. Local breeds are well adapted to the prevailing hot dry conditions, and limited feed resources. They are fat-tailed sheep, open coarse wool and raised mainly for meat and lamb production. There are four major sheep breeds in Egypt; Rahmani sheep in north-Delta, Ossimi sheep in MidEgypt, Barki sheep in the Mediterranean coastal zone, and Saidi sheep in Upper Egypt. Minor local breeds are Fallahi, Wahati, Abudeleik, and Suhagi sheep located mainly in the south and in boarder governorates. Special and unique phenotypic characteristics are described for each breed. Production performance of the main local breeds include body weights, carcass quality, wool, and milk production, are tabulated as reported in the literature. Reproduction performance involving age at puberty, estrous, and breeding activity are discussed. Adaptability of local breeds to the prevailing subtropical environment, specially heat stress are presented. Key issues as the advantages of the local breeds, within the ongoing debate on breeding adapted law producing local animals, vs. high producing low tolerant exogenous breeds are discussed. Improvement programs for local sheep breeds requires sort of nucleus flock structure, as breeders association or village flocks, and the utilization of the recent findings of genomic analysis.

In this study, the effects of four different doses of green tea (0.0, 0.250, 0.50, and 0.750 g/kg) on the nutritional status, blood profiles, and antioxidant status of broiler chickens were investigated. A total of four equal groups, each with four duplicates, and ninety sex-day-old, unsexed broiler chicks were reared in battery cages. Feed and water were offered ad libitum till the termination of the trial at 6 weeks of age. Throughout the whole trial period, the treatment supplemented with 0.750 g/kg of dietary green tea had the highest LBW. In contrast to the other groups, feeding the diet containing 0.500 g/kg of green tea increased FI during the whole study period. Over the course of the entire experiment, broilers fed a food supplemented with 0.500 g/kg green tea demonstrated considerably higher FCR than other experimental groups. Green tea-fortified diets did not significantly affect any group's bilirubin or HDL levels. However, dietary supplementation with green tea for broiler chicks resulted in significantly higher plasma levels of lipid profile and activity on transaminases compared to the control group. The positive impact of green tea addition in diets on the growth performance and blood parameters of broiler chickens was indicated by study findings.

A trial was carried out to evaluate the effect of dried silage of rumen content (DSRC) and acidifiers on the growth performance of broiler chickens. A total of three hundred and twenty unsexed one day old broiler chicks (Cobb 500) were used. The birds were distributed randomly to eight experimental treatments (40 birds/treatment) with four replicates (10 birds/replicate) in a completely randomized design. The experimental diets for treatments were containing dried silage of rumen content at levels of 0, 5, 7.5 and 10% without or with 0.5g acidifiers/kg diets. The feeding trial lasted for six weeks. The obtained results showed that increasing dietary dried silage of rumen content up to 10% and 0.5g acidifier/kg diet increased significantly marketing weight of chicks, total weight gain, total feed intake and improved feed conversion ratio. Carcass traits and blood parameters were not affected by dietary dried silage of rumen content or acidifiers except HDL which was increased in blood of chicks fed diets containing 5% dried silage of rumen content. From the economic of view, it can be concluded that inclusion dried silage of cow rumen content up to 10% of the diets improve broiler performance and had no adversely effect on carcass traits, immunity or blood parameters. Also, adding acidifiers at a level of 0.5g/kg diet can be improving broiler performance.

Studying aims to evaluate sperm characteristics using aqueous extract of maca added to ram semen extender. Five media of ram semen extenders as M0, M1, M2, M3 and M4 contained different levels of aqueous extract of maca at 0, 5, 10, 20 and 40 μg/mL respectively, were storage at 5C for 5 days,. Then, sperm characteristics as progressive sperm motility, livability, abnormality and intact acrosome and lipid peroxidation (LPO) concentration were estimated. Also, a fertility trial using forty ewes (n=20 in each) were inseminated by M0 (as control) and M3 (as the best sperm parameters). The aqueous extract of maca 20 μg/mL improved previous sperm characteristics and reduced both abnormal sperm and lipid peroxidation (LPO) compared with other extenders during storage at 5C for 5 days. Also, an improvement observed in total pregnancy rate of ewes using M3 (79.17%) compared with M0 (65.38%) after chilling at 5C for 2 days. The results indicate that the aqueous extract of maca maintains spermatozoa characteristics during chilling at 5C for 5 days especially 20μg/mL which maintains fertile ability after the 2 days of chilling.

A crossbreeding experiment was carried out using two selected lines of Japanese quail (the brown line and the white line; lines were established for egg and meat production). A total of 2450 crossbred birds of quail produced from four mating groups (two groups for pure birds and other two groups for cross lines) among three hatches were used in the present study to estimate direct heterosis, direct additive, and maternal effects on the following traits: growth traits: body weight at 0, 2, 4, and 6 weeks of age and average daily gain at different growth intervals (ADG0-2, ADG2-4, ADG4-6, and ADG0-6)and carcass traits: slaughter weight (SW), meat (M%), bone (B%), giblets (G%), and dressing percentages (D%). Results showed that crossing sires of BB with WW dams had the highest body weights and body weight gains recorded from hatch to 6 weeks of age, followed by reciprocal crossing between sires of WW with BB dams. Except for BW4 and body weight gains calculated between different growths periods studied, most body weights recorded at different ages showed a highly significant positive direct heterosis effect. Crossing sires of BB with WW dams had the highest carcass performance, followed by reciprocal crossing between sires of WW with BB dams. The majority of carcass traits studied showed a positive direct heterosis effect, with the exception of M% and G%, where direct heterosis was non-significant.

This study evaluated the beneficial impact of daily oral administration with date palm pollen (DPP) on the reproductive efficiency, parameters of blood, ovarian activity and reproductive hormonal profiles in NZW rabbit does. Does (n=60) were divided into 3 treatments (20 in each) administered with 0, 250 and 500 mg DPP/doe dissolved in distilled water (2 ml) respectively, for 35 d premating. Does were naturally mated with adult NZW bucks at the termination of treatment period (35 d). Both levels of DPP significantly increased pregnancy and viability rates, and litter characteristic at birth and weaning as compared to control. Oral treatment with both DPP levels significantly increased Hb, RBCs and hematocrit, serum total proteins, albumin, globulin and glucose and high-density lipoprotein, while significantly decreased WBCs serum total cholesterol, triglycerides, and lowdensity lipoprotein compared with control. Does receive both DPP levels had significantly improved kidney and liver functions, antioxidants capacity and immune response markers than the control group. Both levels of DPP showed significantly (P<0.05) remarkable improvement of estrogen, progesterone and prolactin of rabbit does comparing with control. Rate of ovulation and embryo quality and quality were increased (P<0.05) by DPP levels comparing with control group. The data showed that orally administration of DPP may help in improving the reproductive efficiency of does via adjusting the hematological and metabolites of blood, reducing lipid profile and peroxidation, improving the antioxidant capacity and immunity, and improving the ovarian activity and embryo quality.

Does (n=60) were divided into 3 treatments (20 in each) administered with 0, 250 and 500 mg DPP/doe dissolved in distilled water (2 ml) respectively, for 35 d premating. Does were naturally mated with adult NZW bucks at the termination of treatment period (35 d). Both levels of DPP significantly increased pregnancy and viability rates, and litter characteristic at birth and weaning as compared to control. Oral treatment with both DPP levels significantly increased Hb, RBCs and hematocrit, serum total proteins, albumin, globulin and glucose and high-density lipoprotein, while significantly decreased WBCs serum total cholesterol, triglycerides, and lowdensity lipoprotein compared with control. Does receive both DPP levels had significantly improved kidney and liver functions, antioxidants capacity and immune response markers than the control group. Both levels of DPP showed significantly (P<0.05) remarkable improvement of estrogen, progesterone and prolactin of rabbit does comparing with control. Rate of ovulation and embryo quality and quality were increased (P<0.05) by DPP levels comparing with control group. The data showed that orally administration of DPP may help in improving the reproductive efficiency of does via adjusting the hematological and metabolites of blood, reducing lipid profile and peroxidation, improving the antioxidant capacity and immunity, and improving the ovarian activity and embryo quality.
