摘要
选取海兰商品蛋鸡１０８只，分为对照和试验Ⅰ、Ⅱ３组，每组３６只，分别饲喂添加０、１００、２００ｍｇ／ｋｇＶｃ的蛋鸡日粮。４２天的试验结果：Ⅰ组提高蛋鸡产蛋数６．３６％，饲料转化效率提高６．７％，经济效益增加１７．０２％；Ⅱ组降低蛋鸡产蛋数１．４５％，降低饲料转化效率２．９４％，比对照组少收入６．３％。说明适宜的Ｖｃ添加量能显著提高产蛋鸡的生产性能。
Hyline commerical layers were selected and divided into three groups control,experimental group 1 and experimental group 2 (36 in each group), and feed the ration for layer supplemented Vitamin C in the dosage of 0,100mg/kg,200mg/kg,respectively during the experimental period of 42 days.The results were as follows :In the group 1,the egg numbers leid by laying hen increased 6.36%;the feed efficiency raised 6.7%;the economic efficiency increased 17.02%,but in the group 2,the egg numbers leid by laying hen dicreased 1.45%;the feed efficiency declined 2.94%;the economic efficiency dicreased 6.3%.It suggested that supplementing Vitamin C of suitable dosage had the effect of raising the performance of layer. \ \
