Abstract
- Objective: This study focused on the effect of dietary metallo-protease and Bacillus velezensis CE 100 on growth performance, carcass parameters, intestinal microflora, footpad dermatitis (FPD), and manure odor in broiler chickens. Methods: One hundred-ten (two-day-old Ross 308) broiler chicks were randomly assigned to five groups with two replicate pens. The dietary treatments were divided to control, metallo-protease groups (A1, added with 0.1%; A2, added with 0.2%) and B. velezensis CE 100 groups (B1, added with 0.5%; B2, added with 1.0%). Results: The feed intake was decreased in A1 and B2 compared to the other group (p<0.05). The liver weight was lower in B2 than in A2 (p<0.05). The Salmonella in the cecum was decreased in A2 compared to control and A1 (p<0.05). However, the lactic acid bacteria were increased in all treatments (p<0.05). The litter moisture content was decreased in A2, B1, and B2 (p<0.05). The litter quality visual score was increased in all treatments (p<0.05). The FPD score and prevalence were reduced in all treatments (p<0.05). The (CH3)2S emission was decreased in all treatments (p<0.05). Conclusion: The present study indicated that both additives improve litter quality and reduce the incidence of FPD. These findings suggest that dietary metallo-protease and B. velezensis CE 100 have the potential to improve the broiler chickens’ welfare. [ABSTRACT FROM AUTHOR]
