【摘要】:选用体质量(1 030±90)kg的健康大通牦牛种公牛24头,采用单因子试验设计,随机区组法分为4组,分别为对照组(基础日粮)、Ⅰ组(基础日粮+200mg/kg维生素C),Ⅱ组(基础日粮+400mg/kg维生素C)、Ⅲ组(基础日粮+600mg/kg维生素C),试验周期120d。结果显示:饲粮中维生素C的添加显著提高牦牛精清中维生素C的含量,与对照组相比显著升高(P0.01);与对照组相比,日粮中维生素C的添加,显著提高了牦牛射精总量、精子密度、鲜精和冻精活力以及精子顶体完整率,降低精子的畸形率;但600mg/kg组牦牛精液品质与400mg/kg组相比有不同程度的降低。与对照组相比,饲粮中不同水平维生素C的添加显著提高牦牛精清中总抗氧化能力(TAOC)、谷胱甘肽过氧化物酶(GSH-Px)和超氧化物歧化酶(SOD)的活性(P0.01),降低精液中活性氧(ROS)和丙二醛(MDA)的含量(P0.01)。结果表明:大通牦牛种公牛日粮中合理的维生素C添加剂量为400mg/kg。
