This work was carried out to evaluate the alleviation ability of <em>Nigella sativa</em> (Ns) and or vitamin C for the toxic effect of aflatoxin B<sub>1</sub> in rabbits diet. Forty New-Zealand White male rabbits (average body weight 1000 ± 10 g) were used in five experimental groups (8 / group) for 6 weeks. The control group (T<sub>1</sub>) fed control diet, 2<sup>nd</sup> group (T<sub>2</sub>) fed the diet with 200 ppb aflatoxin B<sub>1</sub>. The 3<sup>rd</sup>, 4<sup>th</sup> and 5<sup>th</sup> group (T<sub>3</sub>, T<sub>4</sub> & T<sub>5</sub>) fed diets with 200 ppb aflatoxin B<sub>1</sub> plus 1% Ns, 500 mg vitamin C/ kg diet and 1% Ns plus 500 mg vitamin C/kg diet, respectively. Results showed that Ns or vitamin C addition can alleviate the negative effect of aflatoxin B<sub>1</sub> on internal organs weight and histopathological lesions of liver and kidneys.

The experiment was conducted to determine the reproductive performance (kidding rate and litter size) of estrus synchronized local Ardy goats after different protocols and trans-cervical artificial insemination (TC-AI). This experiment was conducted at the beginning of their non-breeding season. Total of 90 Ardy does were randomly allotted into 6 similar groups of 15 in each and treated as the following: group 1: does were synchronized with a controlled intra-vaginal devices release (CIDR) for 14 days + injecting (i.m.) 600 i.u. of equine Chorionic Gonadotrophins (eCG) at withdrawal time; group 2: does were received two doses (10 mg/dose) of PGF2α at 11 days apart; group 3: does were treated with insertion of progesterone sponges for 14 days + injecting 600 i.u. of eCG at withdrawal time; group 4: does were treated with GPG method (day 1: the does were given a dose of 25 µg of GnRH (Cystorelin) ; each doe was injected with 10 mg ofPGF2α on day 7 and at the 2<sup>nd</sup> GnRH dose on day 9; group 5: does were synchronized naturally by using male effect where a teaser ram was introduced to the does and left with them for 20 days; and group 6 (control): does did not receive any hormonal treatment and were left for 20 days with a tested fertile buck. All synchronized does were trans-cervically inseminated (TC-AI) with diluted semen of Ardy bucks. The pregnancy was diagnosed by ultrasonic examination on 40 days post insemination. Results showed that does in G1 and G3 showed clear estrus approximately 36 hours post CIDR and sponge removal and were 8 and 12 hours earlier than those in G4, and G2, respectively. Percentages of does kidded were 53.33, 13.33, 40.00, 20.00, 6.67 and 00.00% in G1, G2, G3, G4, G5 and G6, respectively, and the differences were significant (P<0.05). Multiple birth percentages were 13.33, 00.00, 13.33, 6.66, 00.00 and 00.00% per does kidded in the respective groups. Injecting does with eCG in G1 and G3 at the time of pessary withdrawal was associated with fruitful improvements in the kidding rates. The kidding period in all hormonal-treated does was short (about 7 days) and this is an advantage for synchronizing the estrus in Ardy does.

A total of 630 Arbor Acres broiler chicks one-day old were used to study the effect of probiotic, prebiotic and/or yeast supplementation on the productive performance, immune response and slaughter traits. Chicks were divided randomly into 6 treatments and housed at deep litter in an open house system. Each treatment replicated 3 times (35 chicks per replicate). Treatments were as follows: T1 (control; chicks fed corn-soy basal diet) and in the other treatments diets were supplemented with 1g probiotic/kg diet as Lactobacillus acidophilus (T2), 1g yeast/kg diet as Saccharomyces cervisiae (5x10<sup>12 </sup>CFU/g); (T3),1g prebiotic/kg diet as mannan-oligosaccharide (T4), 1g probiotic+1g prebiotic/kg diet (T5) or 1g yeast+1g prebiotic/kg die (T6). Results indicated that body weight, body weight gain, feed consumption and feed conversion ratio were improved and mortality rate was decreased in response to dietary biological feed additives. Body weight at 42 days of age was significantly heavier by about 29.5, 21.2, 12.4, 11.3 and 9.9% than control in the T6, T5, T4, T3 and T2, respectively. Moreover, all biological additives caused a significant increment in the count of erythrocytes, leukocytes, lymphocytes, heterophils, H/L ratio and the antibody titer against SRBC's. Dressing, internal organs and immune organs relative weights at 42 days of age were significantly improved by using biological feed additives. For all traits, the best values were obtained in T6 followed by T5. Also, T6 gave the best relative economical efficiency (14.70% more than control group). It could be recommended from this study that supplementation the biological additives to broiler diet from 0 to 42 days of age, as above mentioned, has a positive effect on the productivity, immune response, slaughter traits and the economical efficiency.

The appraisal of incorporating whole soy-bean milk (SBM) instead of the traditional egg yolk (EY) in bovine semen extenders was investigated. Semen ejaculates from five clinically normal and sexually mature Holstein bulls were used. Two tris-based extenders titrated with citric acid (mono-hydrate) were used. Both extenders were similar in all ingredients except in that one of them contained 15% EY and the other contained 5% SBM. Efficiency of both extenders was evaluated on the basis of sperm viability during each step of semen freezing and after thawing. The initial bacterial counts in the raw EY & SBM, in the extenders, in the extended semen and in the post frozen / thawed semen were also determined .To confirm the laboratory results, an AI fertility trial using 548 Friesian cows was conducted and conception rates of the inseminates from both extenders were compared.
The post thaw sperm motility was significantly (p< 0.05) higher in SBM than in EY frozen/thawed semen. The recorded values for both estimates were 48.4±1.2 and 43.4±1.0%, respectively. Bacterial counts in the raw cryo-protectants, instant extenders, extended semen and in the post-frozen/ thawed semen were all in-favor of SBM extender (p<0.001).
The AI conception rate in the cows inseminated with SBM frozen semen was higher (64.3%) than that recorded for those inseminated with EY frozen semen (57.6 %).The difference was statistically significant (p>0.05).The results of this study showed that replacing the traditional EY by SBM in formulating the proposed extender resulted in a lower bacterial counts in the extended and post-thawed semen, better sperm post-thaw motility and higher AI conception rates. It is concluded that the use of whole SBM extenders (as free animal-source media) could be recommended for sanitary and efficient freezing of bovine semen.
