摘　　要：为探究不同年龄阶段种公牛合格冻精产量与血清生化指标之间的关系,以及各年龄段种公牛随着年龄增长,对其各项生理指标的影响,最终通过血清生化指标更准确地筛选种公牛。通过对10头西门塔尔种公牛,连续两年在春季进行采集血液,检测部分血清生化指标,结合冻精生产情况,进行对比分析。试验结果表明:随着年龄增长,不同年龄段的种公牛精液密度、合格冻精产量、不同产量种公牛的合格冻精产量以及血清天门冬氨酸氨基转移酶和空腹胰岛素等均大幅度下降(P<0.01)。高产组和低产组种公牛血清中雄烯二酮、脱氢表雄酮、睾酮、血清γ-谷氨酰基转移酶,低产组的锌和血清碱性磷酸酶等指标大幅度上升(P<0.01);高产组和低产组的血清中铜和镁含量增长明显(P<0.05);血清总蛋白和血清尿酸含量下降明显(P<0.05)。因此,注重种公牛日常健康管理,及时给种公牛补给必要的微量元素,合理安排种公牛使用年龄,可以充分发挥种公牛的育种潜力。In order to explore the relationship between the yield of qualified frozen semen and serum biochemical indexes of bulls at different ages,as well as the effect of aging on the physiological indexes of bulls at different ages.Eventually,the stud bulls were scree ned more accurately by serum biochemical indicators.Blood samples were collected from 10 Simmental bulls in spring for two consecutive years,some serum biochemical indicators were detected,and the results of frozen semen production were compared and analyzed.The results showed that semen density,qualified frozen sperm yield,serum aspartate aminotransferase and abdominal insulin levels decreased significantly with age(<0.01).Serum androstenedione,dehydroepiandrosterone,testosterone,and serumγ-glutamyltransferase were significantly increased in both high-yield and low-yield groups,while serum zinc and serum alkaline phosphatase were significantly increased in low-yield group(<0.01).The serum levels of copper and magnesium in the high and low yield groups increased significantly(<0.05).The levels of serum total protein and serum uric acid decreased significantly(<0.05).Therefore,it is necessary to pay attention to the daily health management of breed bulls,timely supply the necessary trace elements,and reasonably arrange the service age of breed bulls to give full play to the breeding potential of breed bulls.
