Abstract:

本试验旨在探讨饲粮中添加大豆黄酮对产蛋后期蛋鸡生产性能、血液指标、经济效益的影响。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,试验组饲喂在基础饲粮中分别添加10、50、100mg/kg大豆黄酮的试验饲粮,试验期12周。结果表明:添加10mg/kg大豆黄酮能极显著提高蛋重(P<0.01);添加50mg/kg大豆黄酮能极显著提高产蛋率、降低料蛋比(P<0.01)。添加大豆黄酮显著提高了蛋鸡血清总蛋白、磷、钙、总胆固醇含量(P<0.05),对采食量、血液常规指标及血清白蛋白含量、谷草转氨酶活性、甘油三酯含量、葡萄糖含量、碱性磷酸酶活性、雌二醇水平和孕酮水平影响均不显著(P>0.05)。从经济效益上看,添加50mg/kg大豆黄酮最好。由此可知,在蛋鸡产蛋后期饲粮中添加50mg/kg大豆黄酮可以改善生产性能,且能够获得较佳的经济效益。
