Fig. 1From: Implication and challenges of direct-fed microbial supplementation to improve ruminant production and healthMode of action of proposed DFMs in the rumen. The roles of lactic acid producing bacteria (LAB), lactic acid utilizing bacteria (LUB), other bacteria that can utilize starch (starch-utilizer), and yeast in rumen fermentation are shown in respect of carbohydrate fermentation and microbial protein synthesisBack to article page
