Recently, Challenge Group published new research results in the Journal of Animal Science: The effects of β-mannanase supplementation on growth performance, digestive enzyme activity, cecal microbial communities, and short-chain fatty acid production in broiler chickens fed diets with different metabolizable energy levels.


Lay Summary

The broiler industry currently faces numerous challenges, especially the significant rise in feedstuff prices, and the economic considerations with regard to feedstuff formulation have become important factors for reducing costs and enhancing benefits. Low-energy diets have been increasingly suggested to control feed costs; however, lower nutrient concentrations may result in reduced performance, thereby increasing attention toward the potential use of feed enzymes. In this study, we have assessed the impacts of β-Mannanase (BM), the major β-mannan degrading enzyme, supplementation on poultry health and digestion. Our study involved a total of 1,296 Cobb broilers, randomly distributed into a 3 × 2 factorial arrangement to evaluate the effects of BM supplementation on growth, digestive enzyme activity, cecal microbial communities, and SCFA production in broiler chickens fed diets with varying ME levels. Our findings confirmed previous research by showing that BM-supplemented diets are effective in improving performance in younger broilers. In addition, we found that both BM supplementation and reduced ME levels also have positive impacts on digestive enzyme activity and intestinal flora in chickens, which might account for improving production performance. These results will be a crucial refence for the scientific implementation of BM supplementation, which may help achieve better performance and intestinal microecology, resulting in higher economic productivity of broiler farms.
