种公鸡弱精子症形成因素的初步研究

Preliminary Study on Factors in Malesasthenospermia of Cocks

本实验选择雪山父母代正常公鸡10只和弱精子症公鸡20只进行精液品质测定和形态学观察,旨在研究公鸡弱精子症的形成因素。结果表明:轻度、中度、重度弱精子症组的精子活力依次减小,且差异极显著(P<0.01);弱精子症组精液的精子畸形率极显著高于正常组(P<0.01),精子活率1显著低于正常组(P<0.01);重度弱精子症组的精子密度和精液量显著低于其他组(P<0.05);正常组睾丸曲精细管上皮完整,而轻度和中度弱精子症组曲精细管上皮部分完整,重度弱精子症曲精细管上皮基本脱落。研究结果表明,睾丸器质性变化可能是影响精液品质的因素,且可能导致种公鸡弱精子症。

To study the factors in the malesasthenospermia of cocks,the semen quality and morphological observation between ten normal cocks and twenty asthenozoospermia cocks were compared.This study showed that the sperm activityof mild,moderate and severe asthenospermia groupdecreased successively,andthere was remarkable difference （P〈0.01） between them.Thesperm abnormalitypercentage of asthenozoospermia group was significantly（P〈0.01） higher than that of the controlgroup.On the contray,sperm motility rate of asthenozoospermia group was significantly（P〈0.01） lower than that of the control group.Sperm density and semen volume of severe asthenospermia group were significantly （P〈0.05） lower thanthat ofthe other groups.Morever,testis seminiferous tubule epithelial of normal group was complete,butmoderate asthenozoospermiagroup＇s were partially complete.Andsevere asthenospermiagroup＇s shedbasically.The results indicated that the structural changes of testis may affect testicular sperm quality,which lead to cock asthenospermia.
