摘　　要：为研究三丁酸甘油酯对断奶仔猪生长性能及养分消化率的影响,选用96头健康、平均体重为(7.93±0.04)kg的长大二元杂种断奶仔猪随机分为2组,每组6栏,每栏8头,对照组饲喂基础饲粮,三丁酸甘油酯组饲喂基础饲粮+0.20%三丁酸甘油酯。预试期3 d,正试期21 d。结果显示,与对照组相比,三丁酸甘油酯组仔猪日采食量提高7.02%(P>0.05),日增重提高11.79%(P<0.05),料重比降低4.14%(P>0.05),腹泻率和发病率分别降低66.67%(P<0.01)和22.22%(P<0.05)。饲粮粗蛋白质、粗脂肪和能量的表观消化率分别提高6.56%(P<0.05)、12.38%(P<0.05)和4.09%(P<0.05)。说明饲粮中添加0.20%三丁酸甘油酯可提高断奶仔猪生长性能和饲粮养分消化率。The experiment was conducted to study the effects of tributyrin on growth performance and nutrient digestibility in weaned piglets. A total of 96 healthy crossbred Landrace ＆#215;Yorkshire weaned piglets with the average weight of （7.93±0.04） kg were randomly divided into 2 groups,and each group had 6 stys with 8 pigs.The control group was fed basal diet,the experimental group was fed with basal diets containing 0.20% tributyrin. There were 3 days for pigs to adapt feed before the experiment which lasted for 21 days.The results showed that compared with the control group,ADFI was increased by 7.02%（P〉0.05）,ADG was significantly increased by 11.79%（P〈0.05）,feed conversion ratio was reduced by 4.14%（P〉0.05）,the rate of diarrhea and morbidity were significantly reduced by 66.67%（P〈0.01） and 22.22%（P〈0.05） respectively.The apparent nutrient digestibility of dietary crude protein,crude fat and energy were significantly gone up by 6.56%（P〈0.05）,12.38%（P〈0.05） and 4.09%（P〈0.05） respectively.These results indicated that adding 0.20% tributyrin to diets could improve the growth performance and nutrient digestility of weaned piglets.
