不同剂量中链脂肪酸甘油酯在断奶仔猪中的应用与效益分析

Application and Benefit Analysis of Medium-Chain Triglycerides of Different Doses on Weaned Piglets

试验选择胎次接近、遗传基础一致、断奶后24～52日龄的仔猪120头,随机分成3组,每组4窝。对照组A在基础日粮中添加豆油0.5%,试验组B在饲料中添加固体MCT（中链脂肪酸甘油酯）0.5%替代添加豆油0.5%,试验组C在饲料中添加固体MCT 2%替代添加豆油2%,从仔猪断奶24～52日龄开始,共28 d。试验结果表明,试验组在日增重、日采食量上均优于对照组且差异显著（P〈0.05）,料重比优于对照组但差异不显著（P〉0.05）,而饲料中添加固体MCT 0.5%替代添加豆油2%,饲喂断奶仔猪市场经济效益最佳。

A total of 120 piglets with approach parity and genetic basis were divided into three groups（group A,B, C）, each with four littermate from weaning age of 24 to 52 days. The control group（group A） fed adding 0.5% soybean oil, group B fed adding 0.5% solid MCT（medium chain fatty acid esters of glycerol） and test group C fed adding 2% solid MCT from the age of 24 to 52, 28 days. The results showed that in the experimental group, gain weight,daily feed intake were better than those in the control group with significant difference（P〈0.05） and feed weight ratio was better than control group, but there was no significant difference（P〈0.05）. The economic benefits of feeding0.5% MCT alternative to add 2% soybean oil to weaning piglets was best.
