Effect Of Methionine, Leucine And Isovaleric Acid On In Vitro Digestibility Of Corn Stover, B. J. Johnson, P. A. Momont, R. J. Pruitt
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
Effect Of Methionine Addition To A Urea-Grain Based Supplement On Digestibility Of Mature Prairie Grass Hay, P.A. Momont, R. J. Pruitt, R. H. Pritchard, P. S. Johnson
Effect Of Methionine Addition To A Urea-Grain Based Supplement On Digestibility Of Mature Prairie Grass Hay, P.A. Momont, R. J. Pruitt, R. H. Pritchard, P. S. Johnson
South Dakota Beef Report, 1989
A digestibility trial was conducted to determine the effect of methionine addition to a grain-urea based supplement on the digestibility of mature prairie hay. Ad libitum hay supplemented with .I Ib supplemental crude protein from either a (1) soybean meal, (2) methionine + urea-grain, (3) sulfur + urea-grain or (4) urea-grain supplement was fed to 20 Hampshire ram lambs. Dry matter, neutral detergent fiber and acid detergent fiber disappearances tended to be higher with methionine or sulfur-urea supplements over urea alone. Diet digestibilities between soybean meal, - methionine and sulfur treatments were similar. Methionine increased apparent nitrogen digestibility of the …
