The purpose of this study was to find out whether the concentration of bile acids in the rumen of healthy cows differs from that of cows with a reduced gastrointestinal passage. The investigations were performed on 277 heifers and cows of the Swiss Braunvieh, Simmental and Swiss Holstein breeds. Forty of these had traumatic reticuloperitonitis, 30 had right or left abomasal displacement, 14 had an ileus of the duodenum, 36 had an ileus of the jejunum and 54 had a caecal dilatation. The other 103 animals had disorders which did not affect the digestive system and were used as controls. The mean (+/- se) bile acid concentration in the rumen fluid of the control animals was 1.0 +/- 0.30 mumol/litre. The bile acid concentrations in the rumen fluid of the cows with a duodenal or jejunal ileus were significantly higher than those of the other groups, demonstrating that bile acids may reflux from the duodenum into the rumen of cows with an ileus in the small intestine.
本研究的目的是查明健康奶牛瘤胃中胆汁酸的浓度是否与胃肠通过量减少的奶牛不同。对277头瑞士褐牛、西门塔尔牛和瑞士荷斯坦牛品种的小母牛和母牛进行了调查。其中40头患有创伤性网胃炎，30头有右或左皱胃移位，14头有十二指肠肠梗阻，36头有空肠梗阻，54头有盲肠扩张。其他103只动物患有不影响消化系统的疾病，用作对照。对照动物瘤胃液中胆汁酸的平均（±标准误）浓度为1.0±0.30微摩尔/升。患有十二指肠或空肠梗阻的奶牛瘤胃液中胆汁酸浓度显著高于其他组，表明胆汁酸可能从小肠肠梗阻的奶牛十二指肠反流至瘤胃。
