Influence of Level of Feed Consumption on Nitrogen Components Reaching the Omasum and Abomasum of Lambs¹

University of Kentucky³, Lexington 40506

Abstract

Four wether lambs were fitted with permanent omasal and abomasal cannulae and fed two dietary levels (500 or 1,000 g per head daily), each of which provided 11.2 g dietary nitrogen to each lamb per day. Significantly (P<.05) more total nitrogen, nonprotein nitrogen, isoleucine, leucine, phenylalanine, arginine, histidine, lysine, alanine, proline, glycine, tyrosine and total amino acids reached the omasum when the higher dietary level was consumed. Significantly (P<.05) greater amounts of nonprotein nitrogen passed through the abomasum daily when lambs were fed 1,000 g of diet as compared with those fed 500 g per day. The general trend was for greater amounts of the individual amino acids to be recovered in the abomasum of lambs fed the higher daily intake, although 9.8 g less total amino acids were recovered in the omasum. A recovery difference of only .7 g per day of total amino acids was found between the omasum and abomasum of lambs fed the lower dietary level.
