摘要
为探索中草药添加剂对种公羊精液品质的影响,用当归(Radix angelicae sinensis)、党参(Radix codonopsis)、黄芪(Radix astragali)、淫羊藿(Herba epimedii)、菟丝子(Semen cuscutae)等19味中草药复方配伍作饲料添加剂,按每头种公羊饲料量1%的比例饲喂3周,对种公羊的性反应和精液品质进行分析研究。结果表明:饲喂中草药添加剂后公羊性反应时间显著缩短;射精量、精子密度较对照显著和极显著提高;每次射精有效精子数达到61.64×109,比对照组增加2.36倍,差异极显著(P<0.01);精子头部畸形率较对照组降低8%(P<0.05);饲喂1周对精液质量有明显改善,饲喂3周至停药1周后可延缓精子质量下降的速度;且饲喂后种公羊的冻后精子活率和精子复苏率较对照和饲喂前显著提高(P<0.05),分别增加38.7%和28.9%。该复方中草药添加剂适用于高频度采精种公羊,可改善公羊的精液品质,提高人工授精过程中精液保存质量,有利于进一步发挥优良公羊的种用价值。
To explore the effect of Chinese herbal medicine on ram semen quality,19 kinds of Chinese herbal medicines as feed additives（adding 1% daily feed quantity per ram） were fed to rams for 3 weeks.The sexual reaction and semen quality of rams were studied after feeding Chinese herbal medicine additives.Results showed that sexual reaction time was shortened significantly compared with contro.Ejaculate volume and sperm density were increased significantly in test groups compared with that in the control group.Effective sperm number was up to 61.64 × 109 every time,which was significantly higher than that in control group by about 2.36 times（P0.01）.Sperm head deformity was about 8% lower than that of control.Semen quality had significantly improved after feeding with Chinese herbal medicine feed additives for one week.The rate of sperm quality decline was delayed until one week after three weeks feeding.After freezing,both sperm motility rate and recovery rate were significantly higher than that of control（P0.05）.Sperm motility rate of tested group increased 38.7% and sperm recovery rate was increased 28.9% over the control after freezing（P0.05）.Therefore,Chinese herbal medicine as feed additives can be used to improve the quality of ram＇s semen,and to improve the storage quality of semen in artificial insemination process.
