| ABSTRACT: Using agricultural by-products in livestock feeds can help farmers reduce feed costs and help food waste generators reduce disposal costs while minimizing the environmental problems associated with this waste.Forty-two New Zealand White rabbit bucks aged 8 months were randomly divided into 7 groups. First group served as control group was fed on the basal diet. Second, 3rd and 4th groups were fed a basal diet supplemented with 1, 2 and 3 % dried lettuce (LT) by-product. The 5th, 6th and 7th groups were fed the basal diet supplemented with 1, 2 and 3% dried cabbage (CB) by-product. Two experiments were performed. The 1st experiment investigated the effect of dietary supplementation with LT and CB on fresh semen quality parameters, including volume, motility %, viability, abnormalities, acrosomal damage, and sperm concentration. The 2nd experiment examined the effect of LT and CB supplementation as well as the storage time on the previous semen quality parameters of cooled semen during storage at 5ᴼ C up to 72 hours. Enzymes activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured. In 1st expriment, results showed that sperm concentration increased (P<0.01) in all LT or CB supplemented groups. However, % of dead and abnormal spermatozoa decreased (P<0.05). Ejaculate volume and motility % increased (P<0.05) in 3% LT supplemented group. Experiment 2 showed that motility percentages increased (P<0.01), however,percentages of dead spermatozoa decreased (P<0.01) in bucks supplemented with 1% and 3% LT compared to control. Also, CB supplementation increased (P<0.01) the percentage of motility while decreased (P<0.01) the percentages of dead and acrosomal damage sperm compared to control. Results showed that ALT and AST levels were lower (P<0.01) in all groups supplemented with LT or CB compared to control. Conclusively, the present results demonstrate that, the highest reproductive performance was achieved when bucks fed diet supplemented with 3% of LT and CB by-products. | ||||
