贵德黑裘皮羊电刺激采精及精液品质分析研究

Research on Electroejaculation and Semen Quality Analysis of Guide Black Fur Sheep

本试验选择40只生长发育良好的贵德黑裘皮公羊,按电刺激法成功采集到36只公羊精液,对其精液品质进行评定分析。结果表明,7只公羊精液品质不达标,其余29只公羊平均射精量为1.3 mL,精子密度为1.68×10^(9)个/毫升,鲜精精子活力均在65%以上,符合《DB63/T 1436-2015藏羊细管冷冻精液技术规程》标准,经灌装冷冻后,解冻后精子活力均在35%以上。

In this experiment,40 Guide Black Fur rams with good growth and development were selected.Semen of 36 rams was successfully collected by electroejaculation method,and their semen quality was evaluated and analyzed.Among them,the semen quality of 7 rams did not meet the standard.The average ejaculation volume of the remaining 29 rams was 1.3 mL,the sperm density was 1.68×10^(9)/mL,and the sperm motility of fresh semen was above 65%,which conformed to the standard of“DB63/T 1436-2015 Technical Regulations for Cryopreserved Semen of Tibetan Sheep in Tubules”.After filling and freezing,the sperm motility after thawing was above 35%.
