【摘要】：为了解橡胶籽饼对蛋鸡生产性能及蛋品质的影响,选取25周龄健康海兰褐蛋鸡72只,随机分为6个组,每个组设4个重复,每个重复3只鸡,对照组饲喂玉米-豆粕型基础饲粮,试验Ⅰ~Ⅴ组饲粮分别配合5%、10%、15%、20%和25%的橡胶籽饼,各组饲粮营养水平一致,试验期16周。结果显示:与对照组相比,试验Ⅰ组和Ⅱ组日采食量显著增高(P0.05),其他3个组差异不显著(P0.05);除试验Ⅰ组外,其余试验组料蛋比显著增高(P0.05);除试验Ⅰ组和Ⅱ组外,其余试验组平均蛋重均显著降低(P0.05);除试验Ⅰ和Ⅴ组外,其余试验组蛋壳厚度显著增加(P0.05);所有试验组蛋鸡体重、产蛋率、蛋黄重、蛋黄比、蛋形指数、蛋壳比和蛋壳重无显著差异(P0.05)。研究结果表明,饲粮中配合5%~10%橡胶仔饼不影响蛋鸡体重、产蛋率,但随配合比例的提高,蛋鸡采食量和蛋壳厚度增加,料蛋比呈现上升趋势,平均蛋重和腹脂率呈现下降趋势,鸡蛋品质不受影响。
