For Silkies without broody occurrence in the first half egg laying cycle, PRLR3 and PRLR6 did not influence egg production traits including age at first egg, weight of first egg, egg weight at 40 wks, and egg number at 40 wks (P>0.05).

• 丝羽乌骨鸡群体中；PRLR3和PRLR6位点变异对未曾发生过就巢的丝羽乌骨鸡产蛋性状(开产日龄、开产蛋重、40周龄蛋重和40周龄产蛋量)影响均不显著(P>0.；05)。
