摘要
采用4×4拉丁方设计,给金堂黑山羊饲喂维生素E浓度不同(常量:30 mg/kg维生素E,10,50,100倍常量的添加量)而其他营养成分均一致的4种日粮,探索日粮中添加维生素E对山羊精液品质的影响。结果表明:日粮中添加维生素E有助于提高山羊采精量、精子密度和鲜精活率,改善其精液品质(P<0.05);随着日粮中维生素E浓度的增加,山羊采精量、精子密度和鲜精活率也随之改善,添加量为常量的50倍(1500 mg/kg)时,精子密度和鲜精活率最佳(P<0.01)。当添加量超过常量50倍时(100),精子密度和鲜精活率有所降低,但与添加量为50倍的试验组差异不显著(P>0.05)。
The objective of this study was to elucidate the effect of vitamin E supplemented in ration with the control((30 mg/kg)),10,50 and 100 times of control on the quality of ram semen by 4×4 latin design with Jing-tang Black Goat.The results showed that vitamin E added in ration significantly improved the density of spermatozoon,the motility of fresh semen and the quality of semen(P<0.05).With vitamin E concentration supplemented in ration increasing,the density of spermatozoon and the motility of fresh semen were increased.However the best motility of fresh semen and the density of spermatozoon were obtained from 50 times of control group.
