Ninety six unsexed one-day old; Ross 308 broiler chicks were randomly divided into 4 treatment groups. Each treatment had 3 replicates with 8 chicks each. The chicks of each replicate were allocated in a cage in a windowless house. The experimental period was divided into two feeding phases, starter (0-3 weeks of age) and grower (4-6 weeks of age). The basal experimental diets had 23.33 and 20.42% crude protein and 3115 and 3162 Kcal ME/kg diet for the starter and the grower diet, respectively. Chicks in first treatment were injected muscularly with saline solution weekly and served as a control. Whereas, in treatments 2, 3 and 4 chicks were injected muscularly with 0.5, 1.0 and 1.5 mg of honey bee venom (BV) extract weekly till 5 weeks of age, respectively. Injection with BV decreased significantly (P<0.05) body weight (BW) at 3 weeks of age, average daily gain (ADG) during the period from 0-3 weeks of age and daily feed intake (FI) during the periods from 4-6 and 0-6 weeks of age. On the other hand, there were no significant differences (P>0.05) in BW at 6 weeks of age, ADG at 4-6 and 0-6 weeks of age, FI during period from 0-3 weeks of age, feed conversion ratio, haemagglutinin antibody titers against (SRBC), aspartate amino transaminase (AST) and alanine amino transaminase (ALT), serum total protein, albumin (Alb.), globulin (Glb.), (Alb./Glb.), cholesterol and total lipids. These data indicate that injection of broiler with BV extract by these doses did not adversely affect the productive performance and physiological traits However,BV extract has the ability to enhance the immune responses of broiler chicks. But more research is needed in future to evaluate the best dose and different supplementation methods. Ali, A. H. H * and K. M.

Whole corn plants at stage of maturity were treated by adding microbial inoculants or formic acid at ensiling to determine the effect of these additives (lactic acid bacterial inoculants (LAB) or formic acid) on the fermentation during ensiling. Nutrients digestion coefficients, nitrogen balance, rumen function and DM,CF degradability of sheep fed rations containing untreated or treated silage. Feed intake, milk production and milk composition of crossbred Friesian cows fed treated or un-treated silage plus 6kg CFM were also studied. The results of silage quality indicated that formic acid silage had lower (P<0.05) value of pH, ammonia nitrogen, total VFA and lactic acid than inoculanted silage and untreated silage. The results of the chemical and physical characteristics indicated a good quality for the untreated or treated silages. Nine Barki meal sheep used in digestibility experiment were assigned into 3 similar groups of 3 each. Animals were fed one of experimental rations R1, R2 or control, which containing inoculanted silage, formic acid treated silage or un-treated silage respectively. The results showed insignificant differences (P<0.05) in digestibility of DM and OM among experimental rations. Highest (P<0.05) CP digestibility and NB observed with ration containing formic acid silage. Moreover all animals fed experimental rations showed positive NB. While, highest (P<0.05) CF digestibility was recorded for the ration containing inoculanted silage. However, nutritive value were significantly (P<0.05) higher with R1and R2 than control. Rumen fermentation and in-situ trails determined using three cannulated female Barki sheep. The main results showed that NH3-N concentration was higher for sheep given the control ration following R1. While, highest (P<0.05) TVFA'S was recorded for sheep fed R1and R2 compared to those fed control ration. On the other hand, microbial protein synthesis was lowest (P<0.05) for sheep fed R1 and R2 than those fed ration containing un-treated silage which recorded highest value. Dry matter and CF degradability showed significant (P<0.05) increased for rations containing inoculants silage than control ration. Ration containing formic acid silage showed intermediate value. Feed intake, milk yield and milk composition were significantly increased for cows fed inoculants silage and formic acid silage. Also, these silage additives showed improved in Net revenue and Economic Efficiency%. These results introduce a novel technique towards making best use of agricultural residues as a compensatory feed for feeding ruminants and minimize such problems of disposal pollution.

Genetic parameters for some milk production traits were estimated in a herd of Holstein Friesian (HF) cattle in Egypt. A total number of 502 lactation records of 300 HF cows sired by 29 bulls form a herd belonging to Alexandria Copenhagen Company for Dairy and Meat Production was used in the present study. Data were collected during 7 years (2005-2011) and analyzed using SAS and WOMBAT. Means of total milk yield (TMY), 305 day milk yield (305-DMY) and lactation period (LP) were 10718 kg, 8805 kg and 397 days, respectively. Parity had no significant effect on all traits, except for 305-DMY (P<0.0001). Season of calving, also, had no significant effect on all traits, except for LP (P<0.0025). Heritability estimates of TMY, 305-DMY and LP were 0.19, 0.25 and 0.15, respectively. The moderate estimate of heritability of 305 milk yield indicated that this trait could be made through selection as well as better managemental practices Repeatability of TMY, 305-DMY and LP were 0.48, 0.39 and 0.34, respectively. Positive genetic and phenotypic correlation coefficients were obtained for all traits and ranged from 0.01 to 0.77 and from 0.12 to 0.75, respectively. Results indicated possibility of genetic improvement of milk yield by selection for 305-DMY only due to having higher estimate of heritability compared to TMY, and also because of its reasonably high genetic correlation coefficient with TMY.

Twenty four New Zealand White (NZW) rabbit does (5-7 mo of age, 2.5-4.6 kg LBW and 1-2 parities) were used to study the effect of induced ovulation by GnRH or PMSG on ovarian characteristics, recovery and measurements of embryos at different stages. Also, 3 fertile NZW bucks were used for natural mating. Rabbit does were divided into 3 groups, (8 does in each). Does in the first group (G1) were injected (i.m.) with 0.2 ml saline solution/doe immediately before mating (control). Does in G2 and G3 were i.m. injected with 35 IU PMSG/doe 48 h before mating and 0.2 ml GnRH/doe at mating, respectively. Ovarian and genital characteristics including weight, length and width of the ovaries, oviduct and uterine horn were determined on the right and left side. Embryos were recovered by flushing from each treated doe slaughtered after 72 h of mating for collection of embryos.Embryos were recovered from each uterine horn and oviduct per doe. Results showed that all ovarian characteristics were not affected by treatment, ovarian side and their interaction.Ovulatory response in terms of average number of bleeding and total follicles, corpora lutea (CLs) not significantly affected by treatment. Rabbit does in G3 significantly (P<0.05) produced the greatest number of embryos/doe and the highest blastocyst rate in vitro, and the highest kindling rate, litter size and viability rate of bunnies.
In conclusion, treatment of NZW doe rabbits with 0.2 ml GnRH/doe (Receptal) at mating may be efficient in in vivo embryo production for embryo transfer and also needed for increasing in vivo fertility of naturally mated rabbit does.

Ninety-six weaned New Zealand White (NZW) rabbits, aged 30 day and weighing average 586±13.23 g were used in this study during winter and summer seasons. In each season, two groups were used; the first group was fed ad libitum a commercial pelleted diet and was kept untreated to serve as a control, while the other group was fed the same diet, but supplemented with 0.2% dried Arak powder. Daily weight gain, feed intake and some thermo-respiratory responses were recorded from weaning up to 12 week of age. At this time ten rabbits from each group were slaughtered and carcass characteristics were measured and blood samples were collected. Results obtained showed that final body weight at 12 week of growing NZW rabbits increased significantly (P≤0.05) with Arak inclusion under winter and summer seasons compared to control group, whereas daily feed intake had insignificant differences as Arak treatment. Dietary supplementation of Arak to NZW rabbits either in winter or summer season caused significant (P≤0.05) increased in some haematological and biochemical parameters. Interaction between season and Arak addition effects were significant (P≤0.05 or P≤0.01) on weights of carcass and its components. The lowest values of all thermo-respiratory traits were recorded for rabbits reared during winter season than those in the summer season. Also, results demonstrated that rabbits treated with Arak in the summer season retained rabbit’s respiration rate and rectal and skin temperatures to nearly that of the untreated group in the winter season. The present results indicate an improvement in net profit, by about 20%, for rabbits fed diet containing Arak compared to those fed diet with no addition.
