摘要
采用实验室筛选的菌种固态混合发酵豆粕,比较豆粕发酵前后大豆寡糖及抗原蛋白的降解情况,并进行动物饲养实验。研究结果表明,豆粕中的抗原蛋白发生了大幅度的降解,蛋白含量从46.2%提高到49.7%,氨基酸组成和含量也有一定变化和提高,棉子糖含量由原来的1.2%降解至发酵后的0.1%,水苏糖则被完全降解;动物饲养实验结果表明发酵豆粕产品在平均增重、料肉比和下痢率方面都有很大改善。
Soybean meal was fermented with strains under solid state. The degradation of oligosaccharide and antigen protein was studied. Subsequently, the feeding experiments were performed. Results showed that antigen protein was degraded effectively. The content of protein increased from 46.2% to 49.7%, and the content of raffinose decreased from 1.2% to 0.1% and stachyose was completely degraded. The composition of amino acid had a certain extent change and its content increased. Feeding experiments showed that the fermented soybean meal greatly increased the average weight gain and feed conversion rate, and reduced diarrhea occurrence.
