摘　　要：以笼养绿壳蛋鸡和农大3号矮小型蛋鸡为试验材料,探索蛋鸡在非就巢状态下催乳素基因5′-调控区24-bp插入/缺失(-377^-354 bp)变异与血浆PRL水平和产蛋性能的关系。结果表明,该位点不同基因型(PRL+/+、+/-和-/-型)对非就巢蛋鸡300日龄前的血浆PRL水平和300日龄(40周龄)产蛋性能均无显著影响(P>0.05),表明鸡在非就巢状态下,PRL调控区的24-bp插入/缺失变异与早期血浆PRL水平和产蛋性能无直接关系。In the present study, caged Blue-shell chickens and Nongda 3 （dwarf layers） were used to identify the association of the 24-bp Indel（ - 377- - 354 bp）in PRL 5＇-region with serum PRL level and raying performance in non-broody chickens. The results showed no significant differences （P 〉0.05） in genotypes （PRL ＋/＋, ＋/-, and / ） and serum PRL level prior to 300 d of age as well as laying performance at 300 d （40 wks）, indicating that the 24-bp Indel had no direct effects on early serum PRL level and laying performance in non-broody chickens.
