为研究挥发性脂肪酸（VFA）产生量与粪便VFA排出量的关系,本试验选取25日龄的平均体重为（6.48±0.71）kg的三元杂交断奶仔猪（杜×长×大）20头,安装"T"型回肠瘘管,术后1周,将断奶仔猪随机分成4个处理组,每个处理组5个重复。分别从回肠瘘管处灌注不同水平（约为大肠VFA估测产生量的25%、50%、75%和100%）VFA。同时收集断奶仔猪的粪便,用于测定粪便中VFA的排出量。结果表明:灌注组丙酸、乳酸的排出量均显著高于未灌注组（P0.05）。与对照组相比,灌注水平为25%、50%、75%和100%组的丙酸排出量分别提高了85.3%、67.2%、48.6%和49.2%（P

The study was performed to examine the effects of the endogenous metabolizable glucose in vivo determination method,a total of 20-day-old weaned piglets with（6.48±0.71）kg body weight were randomly divided into four treatment groups,with five piglets allocated to each treatment.The piglets were implanted with T-Cannula in terminal ileum,and were respectively infused into T-Cannula with different levels of volatile fatty acids（25%,50%,75%,100% of the volatile fatty acids yield in the large intestine）.After the weaned piglets survived and del...
