The study focused attention on the relationships between body condition score (BCS) at mating and the reproductive performance of Barki ewes. A number of 541 ewes were mated naturally in autumn for three consecutive years. The flock was managed under a semi-intensive production system, with feeding based on natural pasture grazing over the mating period. Grain flushing was given to the ewes before mating. A five category BCS scale was used to classify ewes one week before joining Average values for BCS at mating were 3.32, fertility, 83 % and prolificacy, 1.03. Year were highly significant (P<.0.01) for body weight but not significant for fertility and prolificacy. Age of dam had a significant effect on weight of dam, fertility and prolificacy. Significant differences were observed for BSC effects on fertility, prolificacy and weight of ewe (P<0.05 to P<0.l), which gave highest values between BCS of (3) and (4) categories. In conclusion, the BCS at mating seemed to affect fertility more than prolificacy.

Present study investigated the effect of adding either commercial or natural probiotics to broilers diets on growth performance, nutrients digestibility and economical efficiency. Avi-Bac (a probiotic product of concentrated lactic acid bacteria and enzymes) was used as a commercial probiotic, while fresh skimmed milk and whey were used as a natural probiotics. Nine hundred one-day-old unsexed Hubbard broiler chicks were randomly distributed into 6 experimental groups, of 150 broilers, with 3 replicates for each treatment group. All diets were formulated to contain the tested levels of both commercial and natural probiotics and were fed in a mash form. The experimental diets were fed in 2 phases: grower (1-4 wk) and finisher (5-6 wk). Avi-Bac was used at level of 0.1%, while skimmed milk or whey were added at levels of 0.5 or 1.0% of the diet. Water and feed were offered ad-libitum throughout the experimental period, which lasted 6-weeks. Broilers receiving the diets supplemented with commercial and natural probiotics showed significantly (P 0.05) in crude fiber digestibility. Also, the data showed that adding both natural or commercial probiotics to broiler diets improved the average values of calculated economical efficiency. The obtained results indicated that natural or commercial probiotic can be used as a growth promoter in broiler diets and it can improve performance, nutrient digestibility and economic efficiency of broilers.

Two experiments (Exp) were carried out to test the effect of different media on in vitro maturation (IVM) (Exp 1; n = 1142 ovaries with 2666 oocytes) and to study in vitro fertilization (IVF) of buffalo oocytes (Exp 2; n = 110 ovaries with 330 oocytes). In exp 1 the collected cumulus oocyte complex (COCs) was allocated to three maturational media; TCM-199 supplemented with hormones (M1), TCM-199 supplemented with epidermal growth factor (M2) and m-SOF (M3) overlaid with paraffin oil before incubating under 5 % CO2 in air at 38.5 C. A part of COCs was fixed to determine the stages of nuclear maturation after 24 hr. In exp 2 the matured oocytes were allotted with sperm suspension before incubating under 5 % CO2 in air at 38.5 C, for 22-24 hr. Presumptive embryos were placed, individually in 96 wells petri dish to determine at 12 hr intervals the kinetics of cleavage up to blastocyst stage. Average of collected COCs per ovary was 2.4 with 86 % of excellent and good graded COC’s. M1 and M2 showed higher (P<0.05) maturation rate vs. M3. After culturing oocyte diameter and perivitalline space increased (P<0.05) relative to preculture diameters, while diameter of ooplasm and thickness of zona pellucida non significantly decreased . Fertilized ova and cleaved embryos (%) were 80.2 and 77.8 %, respectively. Early embryonic cleavage up to 32 cell stage lapsed took 84 hr, while corresponding periods to reach morula, and blastocyst stage were 101 and 134.5 hr, respectively. Out of the fertilized ova 31.5 % reached excellent and good graded blastocyst stage.
