Abstract

Ri hybrid chickens (¼ Luong Phuong × ¾ Ri) were raised up to 12 weeks of age. Two hundred and forty one-day-old chickens of uniform body weight were allocated into 12 boxes. Three diet compositions with a low, adequate, and high methionine content compared with the level recommended by Evonik for coloured-feather chickens. The results show that the high methionine level (0.08% higher than recommended) improved the growth performance of the chickens. The body weight of the chickens fed with high methionine content increased by 8.9–9.7% compared with the other groups at 12 weeks. There was no statistically significant difference in feed intake among the groups. However, feed conversion ratio and protein utilization efficiency were improved in the chickens fed with a high-methionine diet. Meanwhile, the diet with 0.08% methionine lower than recommended did not affect the feed efficiency in chickens.
