A total of 800 healthy one‐day‐old Ross 308 broilers were randomly divided into 4 groups with 4 replicates per group and 50 broilers per replicate for 45 days to compare the effects of cage rearing and flat rearing on growth and slaughter performance of broilers. The results showed as follows: average daily gain (ADG) in treatment 1 was significantly increased by 6.75% compared with that in treatment 2(P＜ 0.01), and that in treatment 3 and 4 was significantly higher than that in treatment 2(P＜0.05). The feed to meat ratio of treatment 1, 3 and 4 was significantly lower than that of treatment 2(P＜0.05), but there were no significant differences among other treatment groups (P＞0.05); The survival rate of treatment 2 was significantly lower than that of other treatment groups (P＜0.05), but there was no significant difference among other treatment groups (P＞0.05). There was no difference in slaughter rate among different treatments (P＞0.05). The half‐eviscerated rate of treatment 2 was significantly lower than that of other treatment groups (P＜0.05). The evisceration rate of treatment 2 and 3 was significantly lower than that of treatment 1(P＜0.05). The leg muscle percentage and breast muscle percentage in treatment 2, 3 and 4 were significantly higher than those in treatment 1(P＜0.05), and treatment 2 was the highest; The abdominal fat percentage in treatment 1 was significantly higher than that in treatment 2(P＜0.01), but there was no significant difference among other groups (P＞0.05). Comprehensive indicators, the effect of cage rearing for 10 days and then flat rearing for 30 days was the best.
