以 2 5%和 4 0 %去毒桐粕等量替代豆、菜粕的配合日粮饲喂牛蛙幼蛙 ,幼蛙成活率为80 .6 %～ 84 .4 % ,平均日增重 1.74～ 1.84 g,饲料系数 1.74 ,与全价饲料相比 ,各指标间均无显著差异 ,并可明显提高饲料效价 ,生产 1kg蛙的饲料成本降低 0 .2 7～ 0 .4 5元 .两种配方中 ,以 2 5%去毒桐粕替代等量豆、菜粕的饲用效果较好 .认为去毒桐粕作为一种新的植物蛋白源生产牛蛙饲料 ,具有较好的开发应用前景 .
The same dosages of 25% and 40% detoxified tung bean meal were substituted for beans, and the mixed ration of rapeseed meal was fed on frogs, the survival rate of frogs was 80.6% -84.4%, and the average daily gain was 1.74 ~ 1.84 g, feed coefficient 1.74, compared with the full price of feed, no significant differences between the various indicators, and can significantly improve the feed titer, feed production cost of 1kg frog reduced 0.27 ~ 0.45 yuan 2. Two In the formula, 25% detoxification of Tong tung instead of the same amount of beans, rapeseed meal feeding effect is better that detoxification tung meal as a new plant protein source production bullfrog feed, has good prospects for the development and application.
