Low fertility in buffaloes with frozen-thawed semen is attributed to sperm damage that is related to formation of ice crystals during freeze/thaw process. This study was conducted to evaluate the freezability of buffalo bull semen extended with four types of extenders, including citrate egg-yolk (CEY, control), CEY with ethanolic Moringa Olifera Leaf Extract (eMOLE) as replacement of antibiotics (CEYm), eMOLE and eMOLE with conventional antibiotic (eMOLEa) with or without Coenzyme Q10 as antioxidant. Semen was subjected to calculate progressive motility, livability, abnormality, acrosome status and integrity of sperm membrane in semen after extending, equilibrating and thawing processes. Four sexually mature buffalo bulls (4-5 y and 400-450 kg LBW) were used for semen collection, and semen was collected twice weekly for 4 successive weeks. Semen ejaculates of ≥70% as mass motility percentage were pooled and extended at 37°C by the four types of extenders without or with 30 µM Co-Q10). Results cleared that progressive motility, livability, abnormality, acrosomal damage and plasma membrane integrity percentages improved (P<0.05) in buffalo semen after dilution, equilibration and thawing, while activity of AST, ALT and LDH in seminal plasma of post-thawed semen reduced (P<0.05) by extension of semen with eMOLE as a new extender. All sperm parameters and enzyme activity were maintained by replacing antibiotics in CEY extender with 4 ml eMOLE. All sperm parameters were improved (P<0.05) and enzyme activity was maintained by adding 30 μM of coQ10 as compared to free extenders. Fertility rate of buffalo cows inseminated with semen cryopreserved in extender (eMOLE+coQ10) was the highest (91.6%), followed by eMOLE without coQ10 (83.3%) and the lowest for control CEY (66.6%). In conclusion, eMOLE as a new extender, is promising for the extension and preservation of buffalo semen. Also, adding 4 ml of eMOLE could be a good substitute for the antibiotic component of CEY as a conventional semen extender. Moreover, supplementing semen extenders with antioxidant addition (30 μM CoQ10) is important to improve function of spermatozoa and sperm fertility of cryopreserved semen of buffaloes.

Bio-Detoxification of Jojoba Meal by Aspergillus oryzae and Impact of its Utilization in Ewes and Lambs' Feeding
Ahlam

The present study was conducted at Maryout Research Station, Desert Research Center, Egypt. Jojoba meal (JM) was treated biologically with Aspergllus orgyzae Fk-923 to study its effects on performance, digestibility coefficient, nutritive value, blood metabolites, and rumen characteristic of sheep. Total of 30 Barki ewes aged 3- 4 years old with an average weight of 33.46 kg were randomly allotted into three experimental treatments (10 ewes of each) to study the reproductive traits of Barki sheep. The experiment lasted for 150 days to cover the pregnancy period. After weaning eighteen growing lambs with average live body weight of 15.41kg, were used in feeding trial 210 days (six lambs of each). The experimental rations (R1, R2 and R3) of treated jojoba meal (TJM) at level of (0, 7% and 14%) as a replacement of cotton seed meal, respectively. The results indicated that the analysis of experimental rations' components demonstrated that the experimental rations were similar in its chemical composition but there was a slight increase in the crude protein content with increasing the percentage of jojoba meal (for the slight decrease in CF content). During early pregnancy, ewes consumed 14% of treat jojoba meal had lower total crude fiber intake than those of R1 (control) and R2 groups. During late pregnancy, the intake levels of total dry matter, crude protein and crude fiber were higher in lambs feed the control ration compared to both 7 and 14% (TJM). During the early pregnancy and late pregnancy, changes in body weight of sheep were not significantly affected by type of diets. Digestibility coefficients by lambs fed 14% JM (R3) showed numerically higher digestion values of DM, OM, CP, CF, NFE and NDF followed by those feed 7% JM (R2) than the R1 (control). Lambs fed jojoba meal had higher TDN and the digestible crude protein (DCP) improved with increasing percentage of JM. Also nitrogen balance as % of nitrogen intake was higher in animals fed R3 and the lowest value was in R2. Feed conversion values as DM, TDN and DCP were improved for lambs fed the control followed by rations containing 7 and 14% JM treated with fungi, respectively. Providing treated JM with fungi (R2 and R3) improved the pH values. The opposite trend was observed for rumen ammonia concentrations (NH3-N) and total volatile fatty acids values (TVFA's), which found to be low before feeding, then increased at 3 hrs. post feeding and returned to decrease at 6 hrs. post feeding but NH3-N levels increased at 6 hrs. post feeding for R1 and R3. There were no significant (P>0.05) differences in creatinine, total protein, albumin, globulin, AST, ALT, T3 and T4 levels. The economic parameters for R3 was the best followed by R2 compared with control ration (R1). It could be concluded that 14% treated JM with fungus can be used in growing lambs' ration.

A field study was conducted to assess the effect of mono- and polyculture systems in net Hapas of monosex Nile tilapia (Oreochromis niloticus), striped mullet (Mugil cephalus) and /or thin-lipped mullet (M. capito) at different stocking ratios on growth performance, feed efficiency, chemical composition of the whole body, and economic efficiency parameters of experimental fish for 107 days rearing period. Five experimental treatments were represented as 100% Nile tilapia (T1, monoculture); 75% Nile tilapia: 25% striped mullet (T2, polyculture); 75% Nile tilapia: 13% striped mullet: 12% thin-lipped mullet (T3, polyculture); 50% Nile tilapia: 50% striped mullet (T4, polyculture) and 100% striped mullet (T5, monoculture). Fish ofT2 showed the highest significant of all growth performance, feed utilization, and economic efficiency parameters followed by the same fish species reared in polyculture system (T4) at stocking ratio (50%: 50%) compared to other experimental fish-culture systems. Generally, it could be recommended that rearing monosex O. niloticus in polyculture system with M. cephalus at stocking ratio 75%: 25%, respectively (T2) is more effective than other aquaculture systems under the experimental conditions of the present study.

The purpose of this trial was to study the effects of Sccharomyces cerevisiae (Scc); Aspergillus awamori (Asp); lactobacillus (Lac) and its mixtures as Probiotics in Gimmizah hens diets on egg quality, plasma lipids, and fatty acid profile in egg yolk. ninety six, 28 weeks old hens were fed on: layer diet as control group; layer diets contained, 0.10% Scc ; 0.05% Asp; 0.10% Lac or a mixture of Scc and Asp; Scc and Lac; Asp and Lac; Scc, Asp and Lac. The experimental period was 16 weeks. Egg and albumen weights were increased in all treatments compared to the control group. The synergistic effects (P<0.05) of Scc, Asp and Lac on egg weight and yolk color scores were observed. Dietary experimental treatments did not affect the weights of the shell and yolk, also, the height of the egg yolk or albumen. On the other hand, the synergistic effect attributed to the combination of Asp and Lac caused significant reduction in plasma total cholesterol, triglycerides and LDL (P<0.01), while, Plasma HDL increased significantly (P<0.01) in all treatment groups as compared to control group. Interestingly, the saturated (SFA) and unsaturated fatty acids (USFA) in egg yolks of the treatments compared to the control. In conclusion, the combined supplementation ofthe biological growth promoters (Saccharomyces cerevisiae, Aspergillus awamori and Lactic acid bacteria) in the henʼs diet can change the fatty acid composition of the egg yolk and improve egg quality.
