phagostimulant

In my opinion , there are three main reason , the low efficiency of compound feed of crab , the poor palatability and the lack of perfect phagostimulant .

究其原因，主要是河蟹配合饲料的使用效率不高和适口性较差，缺少理想的河蟹诱食剂。

In this study , we added phagostimulant used in fish and shrimp , different kind and different dose , to base diet containing 30 % fish meal , initial screening of high activity crab phagostimulant .

本研究通过向含有30%鱼粉的基础饲料中添加不同种类和不同剂量的鱼虾类诱食物质，初步筛选出对河蟹具有较高诱食活性的诱食剂单体。

On this basis , we designed orthogonal by made several combinations of different phagostimulant of high activity according to certain proportion .

在前一工作的基础上，将诱食效果较好的不同诱食剂按照一定比例，设计制成多种诱食剂的组合，采用正交分析法进行试验。

A survey of researching progress on lycine nutrition mechanism was made , involving in the applications of transmethylation , metabolism of amino acid , protein and fat , resistance of disease and stress , regulation of osmotic pressure and phagostimulant .

从甜菜碱的转甲基功效，参与氨基酸、蛋白质及脂肪代谢，抗病、抗应激效应，调节渗透压，诱食效应等方面的应用情况，阐述了甜菜碱营养机理的研究进展，为进一步开发利用甜菜碱提供参考。
