摘要
选取 2 6周龄的海兰商品蛋鸡 30 0只 ,分为对照组和试验Ⅰ、Ⅱ组 ,每组 1 0 0只。分别饲喂添加 0、1 0 0、2 0 0mg/kg维生素C的蛋鸡日粮。为期 30天的试验结果表明 :Ⅰ组提高产蛋数 6.44% ,饲料转化率提高 6.75 % ,经济效益增加 1 7.0 6%。Ⅱ组的产蛋数降低 1 .1 7%,饲料转化率下降 2 .95 % ,比对照组少收入 6.0 1 %。
300 Hyline commercial layers were selected and divided into three groups control , experimental group Ⅰand experimental group Ⅱ ( 100 in each group ) , and feed the ration for layer supplemented Vc in the dosage of 0?100?200mg/kg ,respectively during the experimental period of 30 days .The results were as follows : In the groupⅠ ,the egg numbers laid by laying hen increased 6.44% , the feed efficiency raised 6.75% ,the economic efficiency increased 17.06% . but in the group Ⅱ ,the egg numbers laid by laying hen decreased 1.17% , the feed efficiency declined 2.95% , the economic efficiency decreased 6.01% . It suggested that supplementing Vitamin C of suitable dosage had the effect of raising the performance of suitable dosage had the effect of raising the performance of layer.
