本试验旨在研究碱式氯化锌对蛋鸡生产性能、蛋品质及蛋黄中锌沉积量的影响。选取240羽东乡黑羽绿壳蛋鸡随机分成4组,每组6个重复,每个重复10羽。A组为对照组,饲喂基础日粮,B、C、D组为试验组,分别在基础日粮中添加80、120 mg/kg和160 mg/kg碱式氯化锌。预试期7 d、正式期28 d。结果表明,与对照组相比,从第二周开始,各试验组产蛋率不同程度提高,各试验组料蛋比有所下降;试验各组间蛋壳厚度、蛋形指数、蛋黄色泽和哈氏单位差异均不显著;B组和D组蛋黄中锌含量显著高于对照组（P

The experiment was conducted to study the effects of basic zinc chloride on laying performance, egg quali- ty and zinc content in yolk of laying hens.Two hundred and forty green shell laying hens were randomly assigned to 4 groups with 6 replicates per group and 10 hens per replicate.The laying hens of group A were fed with basal diet,and those of groups B, C ,D were fed with basal diets containing 80,120 mg/kg and 160 mg/kg basic zinc chloride respectively. The experiment lasted for 35 days,including 7 days for pretest.The results showed that ...
