为探讨绿茶粉对蛋鸡生产性能、蛋品质及蛋黄中胆固醇含量的影响,试验选取120只40周龄健康东乡黑羽绿壳蛋鸡随机分成4组,每组5个重复,每个重复6只鸡,A组为对照组,B、C、D组为试验组。A组饲喂基础饲粮,B、C、D组在基础饲粮中分别添加0.4%、0.8%和1.2%绿茶粉。预饲期7 d,正式期21 d。结果表明,各试验组的产蛋率、平均蛋重、料蛋比和死淘率差异均不显著;各添加组的蛋壳厚度和蛋比重均较A组有一定程度的提高,其中D组鸡蛋蛋比重显著高于A组（P

The experiment was conducted to study the effects of green tea powder on laying performance, egg quality and cholesterol content in yolk of laying hens.One hundred and twenty 40-week-old green shell laying hens were random- ly assigned to 4 groups with 5 replicates of 6 each.The laying hens of group A were fed with the basal diet,and those of groups B ,C and D were fed with the basal diet supplemented with 0.4 % ,0.8 % and 1.2 % green tea powder,respectively.
