Low-protein fish meal-free grass carp puffed mixed feed

Abstract

The invention discloses low-protein fish meal-free grass carp puffed mixed feed which comprises the following raw materials: bean pulp, fermented bean pulp, wheat, rapeseed meal, cottonseed meal, wheat middling, rice bran, soybean oil, fish soluble, monocalcium phosphate, bentonite, zeolite powder, choline chloride, salt, composite vitamins, composite mineral salts, active essentiale, composite microecologics and a composite immunopotentiator. As fish meal is replaced by high-quality animal and plant protein sources, the problem of essential amino acid composition balance is effectively solved; due to addition of the active essentiale such as bile acid, L-carnitine, taurine, plant flavonoids and marine organism active substances, digestion, absorption and catabolism of grass carps to fat can be promoted, and liver and gall diseases can be prevented. As no fish meal is used in the feed, the protein resource is saved, and the cultivation cost can be lowered; and because of low protein, the essential amino acid balance is good, the burden of organs of the grass craps is alleviated, and the diseases can be reduced.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a low-protein, fishmeal-free grass carp extruded compound feed. Background technique [0002] Grass carp has become the main species of freshwater aquaculture in my country because of its high feed utilization rate, low breeding cost, and fast growth rate. However, with the rapid development of feed fish farming and the increase of grass carp breeding density, the high morbidity and high mortality of grass carp are difficult to treat, causing huge economic losses to farmers. [0003] Some research studies have shown that the above problems may be related to the choice of feed. In the actual breeding process, in order to one-sidedly pursue the so-called "fast and efficient" breeding effect, farmers often choose high-protein feed, while ignoring the real nutritional needs and health status of grass carp. Especially high-protein feed with unreasonable energy-to-egg ratio can eas...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the high-protein feed with unreasonable energy-to-egg ratio in the prior art is likely to cause fish liver and gallbladder disease and water eutrophication, the present invention proposes a low-protein, fishmeal-free grass carp extruded compound feed according to the nutritional requirements and eating habits of grass carp. The purpose is to correct the misconception that farmers one-sidedly pursue high-protein feed, which is conducive to resource conservation and sustainable development of the ecological environment.
