本试验旨在研究酵母硒和亚硒酸钠对临武鸭血清抗氧化能力、蛋品质及蛋硒存留动态变化的影响。试验选用29周龄产蛋率接近的健康临武鸭240只,随机分为3组,每组5个重复,每个重复16只。对照组饲喂基础饲粮(不补充外源硒,硒含量为0.183 mg/ kg);试验组在基础饲粮中分别补充0.3 mg/ kg亚硒酸钠或酵母硒,饲喂42 d后,撤除外源硒,连续饲喂基础饲粮10 d。结果表明:1)与对照组相比,饲粮中补充亚硒酸钠或酵母硒对临武鸭生产性能和蛋品质无显著影响(P>0.05),饲粮补充0.3 mg/ kg亚硒酸钠或酵母硒极显著提高了临武鸭血清中硒含量(P

This experiment was conducted to study the effects of sodium selenite and selenium yeast on serum antioxidant capacity, egg quality and dynamic change of egg selenium retention of Linwu ducks. Two hundred and forty 29?week?old healthy Linwu ducks with a similar laying rate were randomly assigned to 3 groups with 5 replicates in each group and 16 ducks per replicate. The ducks in control group were fed a basal diet without adding selenium source (selenium content was 0.183 mg/kg), while the others in experimental groups were fed the basal diet supplemented with 0.30 mg/kg selenium in forms of s...
