【摘要】:本试验采用单因子试验设计,将90只285日龄海兰褐种公鸡随机分为2组,每组3个重复,Ⅰ组为对照组,饲喂基础日粮,Ⅱ组为试验组,在基础日粮的基础上添加1.5%复合饲料添加剂,测定种公鸡采精量、精子活力、精子密度、精子畸形率、种蛋受精率、孵化率和健雏率,研究复合饲料添加剂对种公鸡繁殖性能的影响。结果显示:试验组采精量、精子密度、精子活力较对照组分别提高了24.4%(P0.01)、6.8%(P0.05)、14.6%(P0.01),精子畸形率下降23.1%(P0.01)。试验组种蛋受精率、孵化率及健雏率相比于对照组分别提高了3.2%(P0.05)、4.4%(P0.05)、0.2%(P0.05)。从睾丸组织切片可看出,试验组睾丸组织发育状况及精原细胞活跃状态明显好于对照组。结果表明:该复合饲料添加剂能显著提高种公鸡的精液品质,同时也提高了种蛋的孵化性能。
