This experiment was conducted to determine the effect of methionine and lysine supplementation on growth performance, meat quality and rumen fermentation parameters in growing goats. Twenty Xiangdong black goats with initial body weights of 18.1 ± 2.07 kg were used and randomly assigned into four treatments including: no additive (Control), 1.27% Methionine (T1), 2.45% Lysine-HCl (T2), 1.27% Methionine plus 2.45% Lysine-HCl (T3). After 28 days of feeding, the goats were slaughtered and samples were collected for the study. Supplementation of methionine and lysine had no effect on growth performance, meat quality, tissue chemical composition and rumen fermentation parameters. These findings suggest that the mode of supplementation of methionine and lysine used failed to detect the variation.
