摘　　要：文章旨在研究饲粮中添加葡萄糖酸对仔猪生长性能和肠道食糜中短链脂肪酸含量的影响。试验选取28日龄断奶的三元杂交仔猪100头,饲喂基础饲粮7 d后随机分为4组,各组仔猪体重接近,性别比例一致。试验1、2、3组分别在对照组饲粮中添加0.4%、0.8%、1.2%的葡萄糖酸,处理42 d。试验结果:与对照组相比,试验1、2组仔猪平均末重分别显著增加6.7%、7.7%(P <0.05),平均日增重显著增加10.1%、11.9%(P <0.05),料肉比较对照组显著降低6.3%、7.1%(P <0.05);试验1、2、3组仔猪空肠食糜中乙酸浓度显著增加99.2%、125.6%、45.7%(P <0.05),丙酸浓度显著增加44.4%、38.9%、25.4%(P <0.05),总短链脂肪酸显著增加33.1%、21.6%、14.7%(P <0.05),此外,试验1、2、3组仔猪盲肠食糜中丙酸浓度较对照组分别增加33.5%、45.3%、26.9%(P <0.05),丁酸浓度增加38.2%、59.3%、64.0%(P <0.05),总短链脂肪酸浓度增加10.6%、17.7%、14.2%(P <0.05)。结果表明,饲粮中添加葡萄糖酸显著提高仔猪生长性能及肠道食糜中短链脂肪酸浓度,添加量为0.8%时效果最好。The aim of this study was to evaluate the effects of dietary gluconic acid on the growth performance of piglets and the content of short-chain fatty acids in intestinal chyme. 100 28-day-old weaned ternary crossbred piglets were selected. After 7 days of feeding the basic diet,were divided into 4 groups. The piglets in each group were close in weight and the gender ratio was consistent. For groups 1,2,3,0.4%,0.8%,and 1.2% gluconic acid were added to the control diets for 42 days. Results :The last weight of pigs in the groups1,2 increased by 6.7% and 7.7%(P < 0.05),and the ADG increased by 10.1% and 11.9%(P < 0.05). The F/C was lower by 6.3% and 7.1%(P < 0.05). The acetic acid in the jejunum of pigs in groups 1, 2 and 3 increased by 99.2%,125.6% and 45.7%(P < 0.05),and the content of propionic acid increased by 44.4.%,38.9%, 25.4%(P < 0.05),T-SCFA increased by 33.1%,21.6%,and 14.7%,(P < 0.05). In addition,the content of propionic acid in cecal chyme of pigs in groups 1,2,and 3 were tested,the increase was 33.5%,45.3%,26.9%(P < 0.05),the butyric acid increased by 38.2%,59.3%,64.0%(P < 0.05),and the T-SCFA content increased by 10.6% and 17.7%. 14.2%(P < 0.05). It was indicated that the addition of gluconic acid to the diet significantly improved the growth performance of piglets and the contentof short-chain fatty acids in intestinal chyme. When the addition amount was 0.8%,the effect was the best.
