摘要: 为了减少无特定病原 (SPF)蛋鸡的猝死率 ,提高产蛋率 ,对SPF蛋鸡产蛋中后期进行了限饲试验 ,每只鸡日食量由 12 5g减少到 10 7g。结果表明试验组再未出现猝死现象 ,且其产蛋率平均比对照组高约 5 %。

Abstract: In order to decrease the amount of sudden death and increase the rate of laying, we trided to limit the feed uptak for specific pathogens free(SPF) layers, which was in their medium or late term of laying. One layer's feed was reduced from 125g to 107g per day. The result shown that there's no sudden death in test group and the laying rate is about 5 percents more than the control group on average.
