中草药添加剂对种公鸡精液品质及冷冻效果的影响

试验选取27只40周龄‘安卡红’种公鸡,通过预试期的采精训练和精液品质测定,挑选采精成功率低、精液污染率高、精液量少、精液稀薄的9只为试验Ⅰ组,其他18只随机分成Ⅱ、Ⅲ组,Ⅰ、Ⅱ组在基础日粮中分别添加2%配方一和配方二中草药,Ⅲ组饲喂基础日粮,探讨中草药添加剂时种公鸡精液品质及冷冻效果的影响.结果表明:Ⅰ、Ⅱ组种公鸡的采精成功率、采精量、冷冻前后精子活率和精子密度有了显著提高(P<0.05),极显著降低冷冻前后精子畸形率和精液污染率(P<0.01),并具有后效应(停药后10d仍有效应),说明日粮中添加2%中草药可显著改善种公鸡的精液品质和冻后效果.

Effect of Chinese herbal medicine additives on semen quality and freezing effect of cocks

To explore the effect of Chinese herbal medicine on cock semen quality and freezing effect.The test selected 27 forty-week-old breeder cocks,via semen collection training and the test of semen quality,selected 9 cocks for groupⅠ(the group needs to improve),which had lower success rate of semen collection,higher pollution rate of semen,less semen volume and thinner semen,the other 18 cocks were randomly divided intoⅡ,Ⅲ.GroupⅠ,Ⅱ fed with basic diets supplemented with 2% different Chinese herbal medicine,groupⅢ fed with basic diets.The results showed that the groupⅠ,Ⅱcould significantly improve the semen volume,the semen motility rate,the semen concentration,success rate of semen collection and the semen motility rate after freezing(P<0.05);great significantly reduce the semen abnormal rate,the semen abnormal rate after freezing and pollution rate of semen(P<0.01);and have after-working(delayed until 10 after feeding).Therefore,Chinese herbal medicine as feed additives can be used to improve the quality ofcock's semen,and to improve the freezing effect.
