Abstract
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 , All rights reserved.
