Abstract：
The study assessed the influence of rapeseed meal (RSM) fermented using Bacillus subtilis 87Y on the feed microbiota, intestinal microbiota, blood biochemical parameters, and content of minerals in the blood plasma and faeces of piglets. Modulation of the microbial composition of feed containing fermented rapeseed meal (FRSM) and of the faeces of pigs consuming it was observed. There was a significant increase in the number of lactic acid bacteria (LAB) and a decrease in the total number of coliforms and Clostridium perfringens in the faeces of animals from the experimental groups. FRSM in the diet of piglets was shown to improve the mineral balance by increasing the levels of P, Ca, and Mg in the blood plasma and reducing their amount in the faeces. A beneficial effect on parameters of protein and lipid metabolism was also noted, resulting in an increase in the levels of total protein (TP) and albumins (ALB) and a reduction in triacylglycerols (TG) and low-density lipoprotein (LDL) cholesterol in the blood plasma of the piglets. The research results indicate that the presence of FRSM in the diet of weaners can be a preventive factor in intestinal dysbiosis and support the maintenance of homeostasis.
摘要：
该研究评估了使用枯草芽孢杆菌87Y发酵的菜籽粕（RSM）对饲料微生物群的影响，肠道微生物群，血液生化参数，以及仔猪血浆和粪便中矿物质的含量。观察到含有发酵菜籽粉（FRSM）的饲料的微生物组成和食用它的猪的粪便的调节。实验组动物粪便中乳酸菌（LAB）的数量显着增加，大肠杆菌和产气荚膜梭菌的总数减少。在仔猪日粮中的FRSM被证明可以通过增加P的水平来改善矿物质平衡，Ca,和镁在血浆中，并减少它们在粪便中的含量。还注意到对蛋白质和脂质代谢参数的有益影响，导致仔猪血浆中总蛋白（TP）和白蛋白（ALB）水平升高，三酰甘油（TG）和低密度脂蛋白（LDL）胆固醇降低。研究结果表明，断奶者饮食中FRSM的存在可以预防肠道菌群失调，并支持维持稳态。
