Effect of dietary probiotics on the semen traits and antioxidative activity of male broiler breeders

This study aimed to investigate the effect of probiotics on the intestinal morphology, intestinal microflora, oxidative activity (biological antioxidant potential), and semen quality of male broiler breeders. For this, 180 Cobb male broiler breeders (60 weeks of age) were randomly distributed into two groups. The control group was fed a basal diet, and the probiotics group was fed basal diet supplemented with probiotics for 6 weeks. Probiotics containing Bacillus amyloliquefaciens TOA5001 improved the above mentioned characteristics of the male broiler breeders. Thus, B. amyloliquefaciens TOA5001 might improve the reproductive performance of male broiler breeders.
