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/m2)、Ⅱ(20 只/m2)和Ⅲ(27 只/m2),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/m2 的饲养密度效果较佳.

Abstract

The purpose of this experiment was to determine the effects of different feeding densities on the performance of Ross 308 white broilers.297 7-day-old broilers were randomly divided into 3 groups,group Ⅰ(13 broilers/m2),group Ⅱ(20 broilers/m2)and group Ⅲ(27 broilers/m2),with 9 replicates per group for 32 days.The results showed that the daily gain of broilers in group Ⅰwas significantly higher than that in group Ⅱ and Ⅲ(P＜0.05);Feed intake of broilers in groupⅠwas significantly higher thanthat in group Ⅱ and Ⅲ(P＜0.05);The feed-meat ratio of broilers in group Ⅰ,Ⅱ and Ⅲ was 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/m2 is better under this test condition.
