The nutritional benefits of rye (and therefore rye bran) are mainly due to its high content of fermentable dietary fiber, the non-starch polysaccharides (NSP). Microorganisms in the large intestine are able to convert these into short-chain fatty acids (SCFA), including butyrate. Butyrate strengthens the epithelial barrier function in the colon by nourishing the enterocytes and inhibiting the spread of in the intestinal tract. Therefore, the aim of this study was to test under field conditions whether a diet with rye or rye bran as the main ingredient for gilts, sows, and weaned piglets is associated with a lower prevalence. Depending on the age groups, between 20-30% rye or between 15-20% rye bran was used in the experimental group. A total of = 1983 boot swabs, = 356 fecal samples, and = 1909 serum samples were examined. The results of this study show that rye or rye bran at the levels used had no apparent effect on the number of positive samples. However, the OD values in the experimental groups were significantly lower than in the control group. This suggests that the use of rye leads to a lower incidence of infection, but this effect could not be proven from swabs.
黑麦（以及因此的黑麦麸）的营养益处主要归因于其可发酵膳食纤维（即非淀粉多糖，NSP）的高含量。大肠中的微生物能够将这些物质转化为短链脂肪酸（SCFA），包括丁酸。丁酸通过滋养肠细胞和抑制肠道内的[此处原文缺失内容]传播来增强结肠中的上皮屏障功能。因此，本研究的目的是在田间条件下测试以黑麦或黑麦麸作为后备母猪、母猪和断奶仔猪主要成分的日粮是否与较低的[此处原文缺失内容]患病率相关。根据年龄组，实验组使用了20% - 30%的黑麦或15% - 20%的黑麦麸。总共检查了1983份靴拭子、356份粪便样本和1909份血清样本。本研究结果表明，所使用水平的黑麦或黑麦麸对[此处原文缺失内容]阳性样本数量没有明显影响。然而，实验组的[此处原文缺失内容]OD值显著低于对照组。这表明使用黑麦会导致较低的感染发生率，但这种效果无法从拭子中得到证实。
