红曲米对蛋鸡生产性能的影响

摘要

选取30周龄海兰灰蛋鸡240只,随机分成4组,饲喂不同添加量的红曲米,研究其对生产性能的影响。结果表明,在蛋鸡日粮中添加1‰的红曲米,可以提高产蛋率、平均蛋重,降低料蛋比;随着红曲米添加量的增大,产蛋率、平均蛋重反而低于对照组,料蛋比高于对照组。说明在蛋鸡日粮中添加适量的红曲米,可以提高蛋鸡的生产性能。%In order to study the effect of red yeast rice on the production performance of laying hens, 240 30-week Hailan gray layers were randomly divided into four groups and then fed with different doses of red yeast rice. Results showed that adding l%e of red yeast rice in layer ration could improve the rate of egg production and average egg weight and could reduce the feed-egg ration. If the amount of red yeast rice is increased, the rate of egg production and average egg weight would lower than control, while the feed-egg ration would higher than control. So the production performance of laying hens could be improved if the right amount of red yeast rice is added in the diet of laying hens.
