摘　　要：为了提高SPF鸡的生产能力和质量 ,在相同的SPF鸡饲养条件下 ,选择分别来源于北京正大和北京科澳协力生产的全价营养蛋种鸡饲料 ,经高压消毒后 ,饲喂品种相同的SPF种鸡 ,结果显示两个鸡群在生产性能方面存在明显差异 (p <0 0 1)。其中饲喂北京科澳协力饲料的SPF鸡群的产蛋率和利用率都明显高于另一个鸡群 ,主要表现在SPF鸡群开产早期的蛋重上和产蛋高峰期后产蛋率的维持上。As the latest version of “Chinese Regulation of Biological Products” and “Chinese Regulation of Veterinary Products” published, more and more viable vaccines sourced from eggs or chickens and quality controls are required to use SPF eggs and SPF chickens. Under the same housing conditions, two testing flocks showed different production ability fed by different diets. Laying rate and egg utility of one flock fed with diet manufactured by Beijing KeAoXieLi Company(flock 2) was higher than other flock with diet produced by Beijing CP group(flock 1). Main differences were occurred on the egg weight at early stage of laying at the age of 24\_32 weeks old and laying rates at the age of 45\_60 weeks old.
