饲料中添加复方中草药对母猪繁殖性能的影响

Effects of compound Chinese herbal medicine on reproductive performance of sow

为了选择合适的复方中草药添加剂,分别进行饲料中添加复方中草药对健康和亚健康母猪繁殖性能影响的研究。结果表明,在健康母猪日粮中添加50 g/d复方中草药饲料添加剂,母猪的平均初生重、28日龄断乳窝重和断乳成活率分别为1.63 kg、83.39 kg和97.04%,分别较未添加复方中草药饲料添加剂的对照组提高了9.40%、17.29%和2.15%,且3项繁殖性状均显著高于未添加中草药的对照组(P<0.05)。在体况较差的亚健康母猪日粮中添加50 g/d复方中草药饲料添加剂,母猪的平均初生重、28日龄断乳窝重和断乳成活率分别为1.54 kg、78.97 kg和92.83%,分别较同样处于亚健康状态对照组的母猪提高了8.45%、17.67%和5.69%,且3项繁殖性状均显著高于未添加中草药的对照组(P<0.05)。表明在日粮中添加中草药饲料添加剂能有效改善母猪的繁殖性能。

In order to select suitable compound Chinese herbal medicine additive,the effects of compound Chinese herbal medicine on reproductive performance of healthy and sub-health sows were studied.The results showed that the average birth weight,28 day weaning litter weight and weaning survival rate were 1.63 kg,83.39 kg and 97.04%,respectively.Compared with the control group without compound Chinese herbal medicine feed additive,it increased by 9.40%,17.29%and 2.15%,respectively,and the three reproductive traits were significantly higher than that of the control group without Chinese herbal medicine(P<0.05).The average birth weight,weaning litter weight and weaning survival rate of the sows were 1.54 kg,78.97 kg and 92.83%respectively when 50 g/d compound Chinese herbal feed additive was added to the diet of sub-health sows.Compared with the sows in the same sub-health state,the three reproductive traits were significantly higher than those in the control group(P<0.05).The results showed that adding Chinese herbal medicine feed additive to the diet can effectively improve the reproductive performance of sows.
