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 ×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.
