The impact of treatment with bee pollen (BP) on the productive performance and some hematological and physiological traits of rabbit bucks were studied under hot climatic conditions prevalent in Assiut during the summer season. A number of 30 rabbit bucks (15 Vline & 15 Moshtohor line); 14 weeks old were divided into three equal experimental groups. The bucks of 1 st group were fed on a commercial basal ration and served as control, while those in the 2 nd and 3 rd groups were fed on the same ration in addition to daily oral supplementation with 250 and 500mg BP/buck, respectively in gelatin capsulated form allover experimental period. The obtained results revealed significant rabbit line differences in total feed intake (TFI/g), RBCs (10 6), total protein (TP), glucose (mg/dl), total lipids (g/L), aminotransferase(ALT/IU/L), IgG (mg/dl), IgM (mg/dl) and Tri-iodothyronine (T3/ng/dl) hormone concentration. While, the differences were insignificant in the productive traits, Hb (g/dl), HTC (%), cholesterol (g/dl), total antioxidant capacity (TAC/mm/l), aspartate aminotransferase (AST), follicle-stimulating hormone (FSH), testosterone (Testos) and Luteinizing hormone (LH) hormone concentrations. The total feed intake of bucks treated with 250 and 500mg BP/buck decreased by 4.45 and 8.48%, but the means of BW (g), BWG (g) and PI (%) increased significantly (P0.01 or 0.05) than those of the control. The means of Hb (g/dl), HTC (%), RBCs (10 6) and Lymphocytes (%) of the bucks treated with BP increased significantly (P0.01 or 0.05) than those of the control. The means of TP, albumin, globulin (g/dl) and glucose (mg/dl) levels as well as TAC (%), IgG (mg/dl), IgM (mg/dl) of the treated bucks significantly (P0.

The present study was conducted to evaluate the effect of orally administration of bee pollen (BP) levels at 500 and 1000mg/buck as capsules form on semen physical characteristics as well as some hematological and physiological traits of rabbit bucks exposed to high temperature under Upper Egypt climatic conditions. A total of 30 rabbit bucks ; 52 weeks old, were equally classified into three experimental groups. Bucks in the 1 st group (control) were fed on a commercial ration, while those in the 2 nd and 3 rd groups were fed on the basal diet and orally administered daily with 500 and 1000mg BP/buck, respectively during the experiment, which lasted 56 days.The obtained findings revealed that the means of white blood cells (WBCs), hemoglobin (Hg), Hematocrit (HCT), MCV (%), total protein (TP) of Moshtohor rabbit bucks were significantly increased, while the total feed intake (TFI) and glucose level were significantly decreased than those of the V-line rabbit bucks.The means of live sperm (%), mass motility (%), conc./ml (10 6 ), conc./ej (10 6 ) and testosterone (ng/ml) in Moshtohor bucks increased significantly (P0.01) by about 4.3, 6.0, 24.0, 28.6 and 16.8%, while reaction time (RT) was significantly decreased by about 20.2% than those of V-line bucks.The bucks treated with both of 500 and 1000mg BP /rabbit had significantly (P0.01) increased means of final body weight (FBW), red blood cells (RBCs), WBCs, Hg, HCT, MCV, TP and Alb, glucose and TAC than the corresponding means of the control group. While, the treatment with BP significantly (P<0.05) reduced TFI and serum cholestrol. 44 EL HAMMADY et al. The means of ejaculate volume, live sperms, mass motility, conc./ml and conc./Ej. (10 6 ) for bucks treated with BP exceeded significantly (P0.01), while the reaction time and sperm abnormalities were significantly (P0.01) decreased as compared with the corresponding figures in the control group.Similarly, the means of glutathione content (GSH) and testosterone hormone concentration were significantly increased in the treated bucks, while the mean malondialdehyde (MDA) was significantly decreased as compared with the control group.Conclusively, from the obtained results it could be concluded that treating rabbit bucks raised under high temperature with both of 500 and 1000mg/ buck significantly improved the semen characteristics, blood parameters, antioxidant activities, and testosterone hormone.

An experiment was conducted designed to evaluate the effect of a probiotic as alternative to antibiotic growth promoters for broiler chicks. One hundred and fifty unsexed one-day-old Ross broiler chicks were randomly assigned to five equal groups; the first was considered the control group, while the second to fifth was the treatments groups. Each group included three equal replicates each of 20 chicks. The ration used in the first group was the experimental ration without any supplements (control) while, those of 2-5 treatment groups were the same ration, but supplemented with antibiotic Neomycin (200 mg/kg diet), probiotic (1g/kg diet), probiotic (1.5g/kg diet), and probiotic (2g/kg diet), respectively. All birds were raised in wire floored batteries with the following dimensions: width: 97 cm; length: 50 cm; height: 45 cm under similar environmental and management conditions. Body weight (BW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR); carcass and some organ weights percentages as well as intestines and ceca lengths were determined at the end of the experiment (42 days of age). The obtained results revealed that birds fed ration supplemented with antibiotic (G2), achieved significantly heavier final BW and higher BWG than birds received different levels of probiotic (G3 to G5) or the control diet (G1). However, birds received 1g or 1.5g probiotic/kg diets (G3 or G4) had significantly higher final BW and BWG than those fed the probiotic diet (G5) and the control diet (G1). Birds fed antibiotic diet (G2) or received 1g and 1.5 g probiotic/kg diets (G3 and G4) had significantly better FCR values than those of birds fed the control diet (G1) and 2g probiotic/kg diet (G5). The total mortality rate of birds in G3 was lower than those of the other groups. Supplementing the diets with antibiotic or probiotics did not affect the percentages of carcass and body organ weights (gizzard, liver, heart, spleen and Giblets) as well as the lengths of intestines and ceca. The abdominal fat percentage in G1 and G4 was decreased compared to the other groups. Therefore, the supplementation of 1.5 g probiotic/kg diet as an alternative to antibiotics in broiler diet is highly recommended to obtain higher growth performance, improved feed conversion, and lower mortality, without adverse effect on abdominal fat and carcass traits.

Three hundred and sixty, 4 weeks old sexed Dandarawi chicken were classified into two equal groups, the first served as the control (C), while the second was the treatment (T). Each group included 90 males and 90 females, divided into three replicates of 60 birds each. The feed was offered two times daily at 10
