THE EFFECT OF THE COMPOUND FEEDS WITH DETOXIFIED TUNG-OIL MEAL FOR YOUNG BULLFROGS

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 .

With the detoxified Tung oil meal by the ratio of 25% and 40% respectively to substitute soybeam meal and rapesead meal as the compound feeds,the feeding experiment of young bullfrogs has been carried out.The results show the survival rate of each group is from 80 6% to 84 4%;the raised weight of the individual is from 1 74 g to 1 84 g a day;the feed coefficient is 1 74.Compared with the complete feed, there is no remarkable difference in all indexes; the feed avaibility is significantly raised,and the price of the feed to produce 1.0 kg frog drops by 0 27~0 45 Yuan.In the two compositions,25% detoxified Tung oil meal feed group gains better feed effect.So we draw a conclusion that the detoxified Tung oil meal has a wide area of exploitation in the manual breed of bullfrogs as a kind of new perfect plant protein resource.
