Description
Technical field
The invention belongs to cultivate field, and in particular to a kind of river crab compound feed and preparation method thereof.
Background technology
River crab is the distinctive aquatic products treasure of China, it is to be of high nutritive value, unique flavor and enjoy great prestige at home and abroad, become China's export
The staple product earned foreign exchange.With developing rapidly for crab farming, to the quality requirement of mixed feed also more and more higher.
Different from the mode that common fish is directly searched for food, river crab is slower to embrace food grazing speed, thus requires that river crab compound feed exists
In water to leach the time longer, or even more than 12h.The common practice for improving river crab material water stability at present is to increase granulation
Modulation time and ring mold compression ratio, and by the way of adhesive, but these methods are limited to present feed processing technology, effect
It is really limited.The digestive organs of river crab are relatively easy, and the ratio very little of alimentary canal length and body length, glandula digestive is undeveloped, thus require to raise
Material raw material has more excellent formula and thinner grinding particle size, and nutriment is digested and assimilated with improving river crab.
