The effect of intraruminal loads of a propionate/butyrate mixture and of intravenous administration of butyrate on the potential difference across the rumen epithelium (PD) was studied in conscious sheep. The PD was elevated during the measurement period 5 to 15 minutes after intraruminal loading with a propionate/butyrate mixture. Intravenously injected butyrate caused a prompt transitory increase in PD. The results show that both intraruminal and intravenous administration of certain short chain fatty acids stimulated the PD indicating altered ion transport properties across the rumen epithelium.
在清醒绵羊中研究了瘤胃内注入丙酸盐/丁酸盐混合物以及静脉注射丁酸盐对瘤胃上皮跨膜电位差（PD）的影响。在瘤胃内注入丙酸盐/丁酸盐混合物后的5至15分钟测量期内，PD升高。静脉注射丁酸盐导致PD迅速短暂升高。结果表明，瘤胃内和静脉内给予某些短链脂肪酸均刺激了PD，表明瘤胃上皮离子转运特性发生改变。
