A positive physiological and productive action on the identified trends improve metabolic processes in rumen, increasing the digestibility of nutrients, increased retention of nitrogen, which leads to faster growth of young cattle.ruminantsL-carnitinemetabolism in the rumensymbiotic microfloradigestibility of nutrientsthe retention of nitrogengrowth bullsжвачные животныеL-карнитинметаболизм в рубцесимбионтная микрофлорапереваримость питательных веществретенция азотарост бычков
