A. Romer et H. Abel, Effects of DL-methionine hydroxyanalogue (MHA) or DL-methionine (DL-Met) on N-retention in broiler chickens and pigs, ANIM FEED S, 81(3-4), 1999, pp. 193-203
Methionine hydroxyanalogue (MHA) was evaluated for metabolic equivalence co
mpared to DL-methionine in practical diets for broiler chickens and pigs, D
iets calculated to be deficient in methionine, 2.1 and 1.9 g kg(-1) in diet
s for chicks and pigs, respectively, were supplemented with MHA(1) or with
molar equivalents of DL-methionine from suboptimal to optimal methionine fe
eding level. A polynomial regression model was used to describe N-retention
in response to the DL-methionine or DL-MHA supplemented diets, Both supple
ments showed equal effects on N-balances of chickens and pigs. N-retention
(as proportion of N-intake) was 0.56 and 0.54 in chickens and 0.51 and 0.51
in pigs for DL-Met and DL-MHA, respectively. (C) 1999 Elsevier Science B.V
