摘　　要：文章旨在探讨不同饲养密度对罗斯308白羽肉鸡生产性能的影响。试验将297只7日龄肉鸡随机分成3组,即处理组Ⅰ(13只/m^(2))、Ⅱ(20只/m^(2))和Ⅲ(27只/m^(2)),每组9个重复(笼),即上层、中层和下层各3个重复(笼),试验为期32 d,饲养至38日龄。结果表明,整个试验期(2~6周龄),处理组Ⅰ肉鸡采食量分别比处理组Ⅱ和Ⅲ显著提高4.28和5.49 g(P<0.05);处理组Ⅰ的肉鸡日增重最大,分别处理组Ⅱ和Ⅲ显著提高2.39和3.11 g(P<0.05);各处理组肉鸡料肉比和成活率差异均不显著(P>0.05)。综合分析,13只/m^(2)的饲养密度效果较佳。The purpose of this experiment was to determine the effects of different feeding densities on the performance of Ross 308 white broilers.2977-day-old broilers were randomly divided into 3 groups,groupⅠ(13 broilers/m^(2)),groupⅡ(20 broilers/m^(2))and groupⅢ(27 broilers/m^(2)),with 9 replicates per group for 32 days.The results showed that the daily gain of broilers in groupⅠwas significantly higher than that in groupⅡandⅢ(P<0.05);Feed intake of broilers in groupⅠwas significantly higher thanthat in groupⅡandⅢ(P<0.05);The feed-meat ratio of broilers in groupⅠ,ⅡandⅢwas not significantly different,and the difference between groups was not significant(P>0.05).Feeding density had little effect on the survival rate of broilers.Comprehensive analysis shows that 13 broilers/m^(2) is better under this test condition.
