Abomasal Nitrogen, Plasma Amino Acids and Nitrogen Balance Responses of wethers to Fed or Abomasally Infused Methionine

Abstract
Nitrogen balance in growing wethers was not affected by the addition of methionine to a corn-soybean meal and wheat straw diet. When the methionine supplemented diet was fed to abomasal fistulated wethers neither protein nitrogen, nonprotein nitrogen or total nitrogen reaching the abomasum was affected by treatment. Oral methionine supplementation also did not affect abomasal or plasma methionine. When methionine was infused into the abomasum there was a trend for increased nitrogen balance and a significant increase in plasma methionine and decrease in plasma threonine. Copyright © 1972.
