| 摘 要： | 选择576只43周龄海兰父母代蛋种鸡,随机分成4组,每组6个重复,每个重复24只鸡,试验期56d,研究日粮中添加0.2%、0.4%和0.6%的活酵素对蛋鸡产蛋性能、料蛋比和经济效益等方面的影响。结果表明,饲料中添加0.6%的活酵素,可改善蛋鸡的产蛋性能和提高经济效益,其中平均日产蛋率比对照组提高4.30%(P>0.05),日产蛋重比对照组多4.52g(P<0.05),降低了破蛋率,饲料转化率提高了6.98%。

| Abstract: | To select Hailan 576 parents on behalf of 43-week-old chicken eggs were randomly divided into 4 groups of 6 repeat,repeat every 24 chickens,8-week trial period to study the diet to add 0.2%,0.4% and 0.6% of live enzyme laying performance of laying hens,eggs than expected and the impact of economic benefits. The results showed that the 0.6% diet of live enzymes,the laying hens can improve performance and enhance economic efficiency,which average daily egg production rate than the control group to increase 4.... |
