Effect Of Methionine, Leucine And Isovaleric Acid On In Vitro Digestibility Of Corn Stover, B. J. Johnson, P. A. Momont, R. J. Pruitt
South Dakota Beef Report, 1989
Two-stage in vitro fermentation was used to evaluate the amino acids methionine and leucine and a branched chain volatile fatty acid, isovaleric acid, as potential additives to a grain-urea supplement for cattle consuming corn stover. Dry matter and fiber digestibility were higher for the husks and leaves than the stalk portion of the corn plant. Providing urea as a source of nitrogen improved dry matter and fiber digestibility. There were no improvements in digestibility or fermentation rate with addition of the amino acids or volatile fatty acid evaluated
