笼养和平养肉鸡饲喂微生态制剂后的生长性能测定

摘要

通过添加微生态制剂饲喂凤翔肉鸡试验来观测其生长性能，结果成活率提高5％，每只鸡多收入3．10元。笼上饲养凤翔肉鸡，70日龄成活率为99．5％，均重2595g；平地饲养成活乎为94％，均重2150g。相差445g。%By adding microecological preparation to feed Fengxiang broiler, we found that it improved the survival rate with 5%, every chicken increased income with 3.10 yuan; cage rearing broiler chickens at the age of 70 days, the survival rate was 99.5%5 average weight was 259595 and the fiat rearing5 its survival rate was 94%5 average weight was 2150g.
