The aim of the present study was to investigate the effects of dietary nutrient level on growth performance, meat quality and sexual maturity of yellow-feathered chickens. Using the completely randomized design, a total of 432 one-day-old Beijing-You chicks were allocated to three nutrient level groups [high (H), middle (M) and low (L) nutrient levels]. For each group, there were 4 replicates of 36 birds each. Feed and water were provided ad libitum. According to the feeding standard of medium-speed yellow-feathered chickens, three growth stages (1 to 5 weeks, 6 to 9 weeks and 10 to 13 weeks) were set up. The three diets had the same ratio of crude protein (CP) to energy at the H, M and L nutrient levels .The results showed that at 1 to 5 weeks, the average daily feed intake (ADFI) and average daily gain (ADG) in L nutrient level group were significantly lower than those in M and H nutrient level groups (P<0.01); the ADG in M nutrient level group was significantly higher than that in L nutrient level group (P<0.05), and the feed to gain was significantly lower than that in L nutrient level group (P<0.05). Dietary nutrient levels had no significant effect on meat quality (P>0.05). The comb weight and comb length in H nutrient level group were significantly higher than those in M and L nutrient level groups (P<0.01), and the comb height was significantly higher than that in M and L nutrient level groups (P<0.05). H nutrient level group had a tendency to increase the ovary weight (P=0.08). Dietary nutrient levels had no significant effect on sexual maturity of the cocks (P>0.05). It is concluded that the M nutrient level can get the better growth performance for medium-speed yellow-feathered chickens. The H level can promote the sexual maturity of the hens.
