摘要: 试验研究了低温环境下采食量对肉种鸡生产性能的影响。选取20周龄体重相近的黄羽肉种鸡432只,随机分成4个饲料水平组,每组9个重复(12只/重复):基础目粮组(C);试验组分别在基础日粮上增加2g(C+2组)、4g(C+4组)和6g(C+6组)日粮,统计产蛋初期不同饲料水平下黄羽肉种鸡产蛋率和蛋重。结果表明:在整个试验周期内,各试验组与基础日粮组间产蛋率差异不显著(P〉0.05);各试验组内产蛋率差异亦不显著(P〈0.05);而C+6组的蛋重显著高于对照组(C)(P〈0.05);各试验组与对照组体重差异不显著(P〉0.05)。结论:在低温环境下,适当增加饲喂量有助于黄羽肉种鸡生产性能的提高。

Abstract: Effects of different feed intake on Huangyu broilers were tested under low temperature in the trial. 432 broilers with similar body weigh at 20 week-old were randomly divided into 4 groups, and respectively fed with different diet level, namely basal diet group (C), basal diet with 2 g feed addition (C+2), basal diet with 4 g feed addition (C+4) and basal diet with 6 g feed addition (C+6). Statistics in egg production rate and egg weight indicated that, in the experimental period, there was no difference between experimental group and basal diet group in egg production rat (P〉0.05), but C+6 in egg weight was higher than that of C (P〈0.05). However, there was no marked difference between C and the other groups in body weight again (P〉0.05). in conclusion, application of addition into feed intake wouht improve the productivity of Huangyu broilers under low temperature to a degree.
