Effect of Bacillus velezensis to substitute infeed antibiotics on the production, blood biochemistry and egg quality indices of laying hens
Effect of Bacillus velezensis to substitute infeed antibiotics on the production, blood biochemistry and egg quality indices of laying hens
The excessive use of antibiotics in the livestock feed industry caused inevitable side effects of microbial resistance. Besides this residual antibiotics in animal-derived foodstuff imposed serious health problems for humans. So this study aimed to investigate the potential use of Bacillus velezensis to substitute antibiotics for poultry production.
