Fermented rapeseed meal (FRSM) was used in the diet of American mink (Neovison vison). An advantage of this product is its prebiotic and functional properties, which can modify the bacterial microbiota of the GIT. A control group and three experimental groups were formed, with 60 animals in each group. The control group received a basal diet and the experimental groups received a diet with a 2%, 4% or 6% of FRSM as a replacement of extruded wheat. Bacillus subtilis strain 87Y was used to ferment the rapeseed meal (RSM). The study was conducted on mink from the age of 16–17 weeks until slaughter. Changes in the microbiota were analysed in samples of the animals’ faeces and intestinal contents. The analyses included determination of the total number of bacteria and fungi, the number of coliforms and Escherichia coli, the total number of anaerobic Clostridium perfringens, and the presence of Salmonella spp. In animals receiving 4% and 6% FRSM (groups II and III), the content of microscopic fungi and the number of C. perfringens bacteria was significantly (p ≤ 0.05) lower than in the animals from the control group (group 0). A decrease in E. coli was observed in all experimental groups (I, II and III), although these differences were not statistically significant. The inclusion of FRSM in the feed ration did not affect the number of lactic acid intestinal bacteria. Analysis of the results obtained from the stool samples showed that the inclusion of FRSM in the ration did not significantly affect the number of microorganisms in each group. However, as in the case of the intestinal contents, in these samples there was a decrease in the total number of C. perfringens in the experimental groups (I, II and III), with a simultaneous increase in the number of mesophilic bacteria in relation to the control. There was no detection of Salmonella bacteria in any of the analysed material.

发酵的菜籽粕作为水貂饮食（Neovison vison）的组成部分，可调节胃肠道微生物群

美国水貂（Neovison vison）的饮食中使用了菜籽粕（FRSM ）。该产品的优势在于其益生元和功能特性，可以修饰GIT的细菌菌群。形成对照组和三个实验组，每组60只动物。对照组接受基础饮食，实验组接受含2％，4％或6％FRSM的饮食，以替代膨化小麦。枯草芽孢杆菌菌株87Y用于发酵菜籽粕（RSM）。该研究从16至17周龄直至屠宰过程中以貂皮进行。在动物粪便和肠内容物的样品中分析了微生物群的变化。分析包括确定细菌和真菌的总数，大肠菌和大肠杆菌的数量，厌氧产气荚膜梭菌的总数以及沙门氏菌的存在。在接收4％和6％FRSM动物（组II和III），微观真菌的内容和数量产气荚膜梭菌细菌是显著（p ≤0.05）比来自对照组（组0）的动物低。大肠杆菌减少在所有实验组（I，II和III）中都观察到了这种现象，尽管这些差异在统计学上并不显着。饲料中加入FRSM不会影响乳酸肠道细菌的数量。从粪便样品中获得的结果的分析表明，定量饲粮中加入FRSM不会显着影响每组中的微生物数量。但是，与肠道内容物一样，这些样品中实验组（I，II和III）的产气荚膜梭菌总数减少，而与之相关的嗜温菌数量同时增加到控制。在任何分析的材料中均未检测到沙门氏菌。
