Low-fish meal tilapia feed

Abstract

The invention provides a low-fish meal tilapia feed. The low-fish meal tilapia feed is prepared by mixing the following raw materials in percentage by weight: 1-2.5 percent of fish meal, 7-10 percent of bean dreg, 30-36 percent of vegetable dreg, 10-21 percent of cotton dreg, 18 percent of sub-meal, 14-16 percent of oil rice bran, 0.5-1 percent of soyabean lecithin, 0.5-1 percent of bentonite, 1-2 percent of mixed premixing material, 0.5 percent of choline chloride, 0.01-0.02 percent of calcium iodate and 0.2-0.4 percent of methionine. The invention uses the vegetable dreg and the cotton dregat maximum instead of fish meal, obviously reduces the dosage of fish meal in tilapia feed, has low prescription cost, low feed coefficient, no poor influence on the health of a fish body and higher cost-performance ratio and can effectively reduce the breeding cost of tilapia.

Description

technical field

[0001] The invention relates to the field of aquaculture feed, in particular to low-meal tilapia feed. Background technique

[0002] In the cost of aquaculture, the cost of feed accounts for about 50%, and the price of feed often depends on the price of protein raw materials in the feed. Because of its high nutritional value and good palatability, fishmeal is the most widely used protein source in aquatic feed. However, with the development of feed industry and aquaculture, the demand for fishmeal is also increasing. Makes the supply of fishmeal increasingly tight, and the price rises. Moreover, due to various reasons such as the gradual depletion of marine fishery resources, environmental protection, and feed costs, the use of fishmeal in future aquatic feed will be gradually limited, and other high-quality and cheap animal and plant protein sources should be found to partially or completely replace aquatic animals. Fishmeal in feed has become one of the k...
