摘要
将25周龄的商品蛋鸡400只随机分成5组,待分组产蛋稳定后,在饮水中添加1.2g/L、0.9g/L、0.6g/L、0.3g/L、0g/L的Na2SO4溶液进行饲喂实验。结果表明,添加Na2SO4的四个试验组饲料转化率和产蛋率均高于对照组,当添加量为0.6/L时,饲料转化率和经济效益最佳。
Randomly put 40,0 25-week-old laying hens into 5 groups. Upon stalbe egg production, we conduct an experiment by adding Ns2SO4 water with different degree of 1.2 g/L, 0.9g/L, 0.6g/L, 0.3g/L, 0g/L. The result shows： feed conversion and laying rate of 4 hen groups fed with Na2SO4 water are higher than that of the check group; when adding Na2SO4 water with degree of 0.6g/L, its feed conversion and economic benefits reach the best condition.
