| 摘 要： | 为探讨日粮锌水平对辽宁绒山羊种公羊精液品质的影响。本试验选用成年健康、精液品质相近的辽宁绒山羊种公羊20只,随机分为4组,对照组饲喂基础饲粮,试验组分别在基础饲粮中添加20、40和80mg/kg的锌。结果表明:①日粮锌水平对种公羊的精液量、精子密度、精子活力和精子解冻后活力影响显著(P<0.05);②日粮锌水平对种公羊的精液pH值、美蓝褪色时间没有显著影响(P<0.05);③日粮锌水平对种公羊的降低鲜精和冻精畸形率有一定的促进作用(P>0.05)。综合鲜精、冻精品质指标,本试验日粮条件下,日粮锌添加量为40mg/kg辽宁绒山羊种公羊的精液品质最优。 |

| Abstract: | The study was conducted to investigate the effect of dietary zinc levels on semen quality of breeding rams of Liaoning Cashmere Goat.A total of 20 breeding rams with weight similar and age similar were randomly divided into 4 groups.The control group was fed a basic diet,and the test groups were 20,40 and 80 mg/kg of zinc added in the basal diet.The result showed that:①There was significant effect by adding dietary zinc to breeding rams on semen volume,sperm concentration,sperm motility and post-thawing motility(P<0.05).②The pH of semen and methylene blue fading time were not markedly affected by dietary zinc levels(P<0.05).③Dietary zinc levels on breeding rams has a certain role in promoting to reduce the fresh semen and frozen semen malformation rate(P>0.05).Based on the quality indicators of fresh semen and frozen semen under the conditions of the experimental diets,semen quality of breeding rams of Liaoning Cashmere Goat is highest with 40 mg/kg of dietary zinc added in the basal diet. |
