Supplementation of carbohydrate enzymes plus protease to the diet of finishing pigs containing 2 protein levels on the effects of growth performance, toxic gas emissions, meat quality, and colonic microbiota community

Abstract

Background Dietary supplementation with exogenous enzymes may positively affect the traits of finishing pigs. The present study investigated the effects of different protein levels and exogenous carbohydrate enzymes plus protease on growth performance, meat quality, toxic gas emissions, and the structure and function of colonic microbiota in finishing pigs.
