| 摘 要： | 本试验选择亚热带气候条件下广州地区的娟姗公牛和荷斯坦公牛各5头,比较两个品种公牛的精液品质(采精量、原精密度、原精活力、细管精液产量、冻后活力、低渗膨胀率及穿透率)。研究表明,荷斯坦公牛每次采精的采精量(16.14±0.06 mL)和细管精液产量(189.17±3.11支)都极显著地高于娟姗公牛(4.74±0.05 mL,158.46±2.64支)(P<0.01);娟姗公牛的原精密度(8.95±0.08亿/mL)极显著地高于荷斯坦公牛(8.32±0.07亿/mL;P<0.01);娟姗公牛原精活力(0.731±0.004)高于荷斯坦公牛(0.729±0.003),但两者差异不显著(P<0.05);娟姗公牛精液的冻后活力(0.355±0.003)极显著高于荷斯坦公牛(0.339±0.003;P<0.01);娟姗公牛冷冻精液的低渗膨胀率(34.50%±0.49%)显著高于荷斯坦公牛(31.21%±0.59%;P<0.01);娟姗公牛冷冻精液对去透明带仓鼠卵的穿透率(84.51%±13.83%)显著高于荷斯坦公牛(81.52%±6.13%;P<0.05)。 |

| Abstract: | Jersey bulls and Holstein Bulls in the semitropical climate in Guangzhou district were used in the present study.Semen quality of the two breeds' was compared.Semen quality was judged on the basis of ejaculation volume,sperm concentration,sperm motility,straw semen production,motility of thawed semen,HOST value and penetration rate.The semen volume and number of straw frozen semen per ejaculation of Holstein bulls were highly significantly more than those of Jersey bulls.The sperm density of fresh semen of Jersey bulls was significantly higher than that of Holstein bulls.Although the motility of fresh semen of Jersey bulls was not significantly higher than that of Holstein bulls,the motility of thawed semen of Jersey bulls was highly significantly higher than that of Holstein bulls,the HOST value and the penetration rate of thawed semen of Jersey bulls were significantly higher than that of Holstein bulls. |
