A total number of 1260 fertile eggs were randomly divided into seven treatments to investigate effect of in ovo-injection of ascorbic, folic acids and their combination at 14 day of incubation on hatchability and subsequent growth performance of broiler chicks. The experimental design was as follow: 1Eggs were without injection. 2Eggs were injected with 0.1ml distiller water/ egg. 3Eggs were injected with 0.1ml solution containing 6 μg ascorbic acid (AA) /egg. 4Eggs were injected with 0.1ml solution containing 75 μg folic acid (FA) /egg. 5Eggs were injected with 0.1ml solution containing 150 μg FA /egg. 6Eggs were injected with 0.1ml solution containing 6 μg AA + 75μg FA/egg. 7Eggs were injected with 0.1ml solution containing 6 μg AA+150μg FA /egg. Hatchability % was improved due to injection of AA6/egg and with combination between AA6 and FA150/egg as compared to the control group. Also, in ovo injected with AA6, FA75, FA150 and AA6+FA75 recorded the best value of live body weight compared to the control group at 28 days of age. In ovo injection of AA, FA and their combination significantly decreased triglycerides levels in serum blood. Also, the level of HDL significantly improved due to in-ovo injected with AA6 and FA75. Therefor, it could be mentioned that in-ovo injection of 6μg AA/egg and 6μg AA+150μg FA/egg in fertile eggs at 14 day of incubation can be applied to improve the hatchability and subsequent growth performance from 1 to 28 day of age.

To synchronize estrus and ovulation for improving pregnancy rate (PR) of repeat-breeder buffaloes, Controlled Internal Drug Release (CIDR) + prostaglandin (PGF2α) was used before service of repeat breeder buffaloes. Total of 20 cyclic lactating buffalo-cows (4-7 years, 400-500 kg, non-pregnant up to 90-postpartum day) and 10 cyclic buffalo-heifers (2.5-4 years, 350-400 kg, not conceived after 3 services) were used in this study. In the 1st group, a CIDR was inserted for 9 days, regardless reproductive status, and then animals were intramuscularly injected with PGF2α 24 h prior to CIDR removal. In the 2nd group, control animals were used at the same interval. Animals in heat were naturally served and blood samples were collected on different days post-service for serum P4 determination. Pregnancy was diagnosed on day 25 post-service. Results showed that overall mean of PR was higher (P<0.01), while serum P4 at estrus was lower (P<0.001) in CIDR than in control, but both parameters were not affected significantly by animal type or CIDR x animal type interaction. Serum P4 at estrus was lower (P<0.05) in pregnant than in non-pregnant, regardless treatment or animal type. At the following post-service days, serum P4 showed the same trend of change, being higher (P<0.001) in CIDR than in control animals and in pregnant than in non-pregnant animals, regardless animal type. It could be concluded that the random usage of CIDR device for 9 days and prostaglandin F2α injection 24 h pre-CIDR withdrawal can be applied to improve pregnancy rate of repeat breeder Egyptian buffaloes.

This study was investigating to examine the effect of mash and pellet diets with normal and low protein and energy levels on broilers performance in finisher period. four hundred eighty unsexed broiler chicks fed two type of (mash and pellet) diet, two protein levels (21% and 19% CP), and two energy levels (3200 and 3000 Kcal/Kg ME) in period 24 to 42 days of age. The weight gain, feed intake, feed per gain, and mortality were examined during the experimental periods (24 -42 d). after sloughed traits were measured at the end of the study (42 days) including gizzard percentage, dressing percentage, abdominal fat percentage and small intestine and their parts percentage. There were significant (P≤0.05) interactions for all parameters were examined except feed per gain, the pellet diets significantly (P≤0.05) improve feed intake, body weight, weight gain and dressing percentage on the other hand pellet diet significantly (P ≤0.05), increase mortality, mash diet influence significantly (P≤0.05) weight of gizzard and small intestine and their parts. The normal protein levels significantly (P≤0.05) increased weight gain, body weight and feed intake, the energy levels did not affect statistically of all parameter.

The current study aimed to evaluate the effect of dietary supplementation with sunflower oil (SFO), flaxseed oil (FSO) or 1% SFO+1% FSO on growth performance, and lipid, testosterone and fatty acid profiles of California rabbit bucks. Number of 24 California bucks having 5.3-5.5 months of age and weighing 2316-2429 g were divided into four groups (n=6). Bucks in the control group were fed free commercial diet, while those in the 2, 3 and 4 groups were fed the same diet with 2% SFO, 2% FSO, or 1% SFO+1% FSO, respectively. Growth parameters were determined during the experiment (16 wk). Serum lipid, testosterone and fatty acid profiles were determined. Results showed insignificant treatment effect on body weight, feed intake and weight gain during the experiment (0-16 wk). The differences in serum triglycerides and total lipids between treatment groups and control were not significant, but triglycerides increased (P<0.05) in FSOthan SFO-bucks. Phospholipids decreased (P<0.05) only by SFO+FSO, while total cholesterol and LDL increased (P<0.05) by SFO or SFO+FSO, but HDL was not affected. All oil types increased (P<0.05) Non-HDL, being higher (P<0.05) in SFO+FSO than in SFO or FSO. Serum Castelli I and II indices, AST and ALT activity, serum total fatty acids and fatty acid profile were not affected by treatment. In conclusion, balancing the ratio between n-6: n-3 fatty acids is important to be the easiest approach to indicate this would be intake of oils rich in n-3 or n-6 fatty acids, such as sunflower and flaxseed

Spirulina platensis (SP) is the powder of microscopic green algae produced and consumed for times all over the world, besides in Africa also for its nutritional and pharmacological properties. Thus, the present study was conducted to evaluate the effects of dietary SP on the reproductive and economic efficiency parameters of adult Red Balady rabbits for 65 days. The results revealed that 0.6 g SP / kg diet led to insignificant increased of the productive performance of adult and kids' rabbits, serum biochemical and economic efficiency parameters. However, this level of SP significantly improved all tested semen quality parameters and serum lipid profiles of adult rabbits compared to those fed the low tested level of SP (0.3g / kg diet) or SP-untreated group. Based in these findings, 0.6g SP / kg diet is more useful level to potentially improve the productive and reproductive performance parameters, which sequentially led to increase the economic efficiency parameters of breeding the adult Red Balady rabbits.

This study was conducted to investigate the effects of supplementing the rabbit diets with Eucalyptus globulus dried leaves (EGL) or its aqueous extract (EGE) on growth performance, nutrients digestibility and blood constituents. A total number of 225 weaned New Zealand White rabbits, six weeks old, were used in this experiment. Treatment groups were ; a control diet (C), T and T were the control diet + 0.25 or 0.5% dried eucalyptus leaves, respectively, T and T were the control diet + 0.05 or 0.1% aqueous extract of eucalyptus leaves, respectively, The growth trail lasted for 8 weeks. At the end of the trial, digestibility nutrient trails were done and nutritive values were calculated, then rabbits were slaughtered and blood samples were obtained. The obtained results could be summarized as follows: Providing rabbit diets with EGL; EGA significantly (P<0.01) increased final live weight, body weight gain and, feed conversion ratio, especially at 0.25% EGL compared to the control. The best FCR were reported to the groups contain 0.25% EGL followed by 0.05% EGE. The digestibility coefficients for OM, CP and nutritive values in terms DCP and TDN of the experimental diets significantly increased with EGL and EGE feeding. Supplemented EGL or EGE to the diets significantly increased (P<0.05) values of hemoglobin concentration, RBC’s, WBC’s count and percentage of lymphocytes. Both EGL and EGE significantly increased blood total protein and albumin, also decreased triglycerides and total cholesterol and has no effect on creatinine and the activity of AST and ALT. It could suggested that using eucalyptus as feed additives for growing rabbits improve growth performance and digestibility, with no adverse effects on blood constituents.
