Abstract:

本试验旨在研究高剂量大豆黄酮对产蛋鸡卵巢组织的影响。选取体重、产蛋率相近的56周龄海兰褐蛋鸡640只,随机分为4组,每组8个重复,每个重复20只。对照组饲喂基础饲粮,试验组饲喂基础饲粮中分别添加10(最高推荐有效量)、50(5倍最高推荐有效量)、100mg/kg(10倍最高推荐有效量)大豆黄酮的试验饲粮。试验期12周。结果表明:添加大豆黄酮对产蛋鸡血清大豆黄酮、雌马酚含量,卵巢重量、组织形态、白介素-1β(IL-1β)阳性细胞数及IL-1β、肿瘤坏死因子-αmRNA表达均没有显著影响(P>0.05)。由此可见,在产蛋高峰后期蛋鸡饲粮中添加适量大豆黄酮可以改善生产性能和蛋品质,但不会促进其卵巢组织增生癌变,是安全的。
