COMMUNITY STRUCTURES OF GUT MICROBIOME UNDER DIFFERENT DIETS IN ANGUS BEEF CATTLE
… lactate, and bile acids under grass-feeding and grain-feeding. We found that microbial communities displayed significant differences in microbiome structure and VFA production. Moreover, increased VFAs in grain-fed group may trigger lactate-associated bacteria growth. Bile acids could promote the …
