Effect of methionine compounds on rumen activity of cows.

Abstract

Rate of degradation of hay was studied, using the nylon-bag technique, in 2 cows given a basal diet without (controls) or with a liquid methionine supplement (LiquimethReg.) or a protected methionine supplement (MepronReg.) providing methionine 25 g daily. After 24 and 48 h incubation methionine supplementation significantly increased degradation of DM, organic matter and cell wall constituents compared with controls. Degradability of crude protein (CP) was significantly increased by methionine supplementation, and degradability was affected by type of supplement with degradability of CP greater with the liquid methionine supplement than with the protected methionine supplement.
