复合菌体系酶法脱毒菜籽粕饲喂肉鸡试验研究

A Trial Study on Meat Chicken Fed with Rape Seed Meal Detoxicated with Multi-Microbes by Ferment Mehtod

研究了复合菌体系酶法菜籽粕脱毒及其应用，采用少孢子根霉菌、乳酸菌等菌种，在适宜的发酵条件下进行脱毒。试验结果表明：菜籽粕中硫代葡萄糖甙（ 简称硫甙） 的降解率约在５０％ ～６０％ 。脱毒菜籽粕对肉鸡的饲喂试验的初步结果表明：在日粮中菜粕的添加量１０％ ～１５ ％ 甲状腺无明显变化，肉鸡的增重亦不受影响。

Rapeseed meal detoxicated with multi-microbes including SPT-3, rhizopus oligosprus and lactics etc by ferment in an appropriate fermentation condition and the application of the detoxicated rapeseed meal were studied. The results showed that the detract ratio of glucosinolates in rapeseed meal was about 50%～60%. And the feeding test indicated that when the contents of the detoxicated rapeseed meal in the dairy feed for chicken were between 10% and 15%, there were no any effects on the body weight gain and no any remarkble changes to thyroid gland.
