摘要
试验选用1日龄健康雏鸡,根据羽毛生长速度进行快慢羽分群饲养,研究羽速基因对莱芜黑鸡早期生长速度和蛋用性能的影响,结果表明,羽速基因对早期生长速度有一定的影响,初生重、2、4、7、10周末快羽系鸡体重显著高于慢羽,但对蛋用性能方面影响差异不显著。
One-day-old chickens were divided into the rapid feathering group and the slow feathering group according to the feather speed gene. The effect of the feather speed gene on early growth and production performance of Laiwu black chicks was studied. The results showed that some effect on early growth of feather speed gene. Day old weight and 2,4,7,10-week body weight of the rapid feathering group was significant higher than that of the slow feathering group. But there have no significant differences on production performance.
