不同类型复合酸化剂在断奶仔猪饲料中的应用研究

Application of Different Types of Acidifiers on Weaning Piglets

将72头断奶1周的杜×长×大仔猪(35日龄)随机分成3组,包括1个对照组和2个试验组。各组的基础日粮相同,对照组为不添加酸化剂的基础日粮,试验1、2组分别添加0.15%普通复合酸化剂和0.15%缓释复合酸化剂,进行28 d的饲养试验。结果表明,添加0.15%缓释复合酸化剂可显著提高仔猪的日增重,降低料肉比、腹泻率和死亡率。

72 Duroc×Landrace×Yorkshire piglets（35 days old,1 week after weaning） were ran-domly divided into 3 groups,including one control group and two experimental groups with the same basal diet, but the control group without acidifier, experimental groups 1, 2 were separately added 0.15% common compound acidifier and 0.15% slow-release compound acidifier. After feeding 28 days,the results showed that adding 0.15% slow-release compound acidifier in weaning piglet′s diets could increase the weight significantly,decrease feed conversion ratio,diarrhea rate and mortali-ty rate significantly.
