Abstract

The present invention provides a Nile tilapia feed which is composed of the following raw materials in parts by mass anabarilius meal 40-50 parts, soybean meal 20-25 parts, alpha-starch 5-8 parts, choline chloride 0.2-0.8 parts, gelatin 5-10 parts, sodium alginate 0-2 parts, casein 50-60 parts, fish oil 5-10 parts, pupa proteins 8-12 parts, soy lecithin 1-5 parts, calcium dihydrogen phosphate 1-3 parts, mineral salt premixes 0.5-2 parts, vitamin premix 0-1 part and compound enzyme 0.01-0.05 part. The Nile tilapia feed uses the fish oil and soy lecithin as fat sources, and the fish meal, casein and pupa proteins as protein sources, explores the optimal fat levels of the Nile tilapia compound feed, and meets nutritional needs and raising standards of Nile tilapia.

Description

technical field [0001] The invention relates to aquaculture industry, in particular to a feed for Nile tilapia. Background technique [0002] In order to maintain the sustainable development of the aquaculture industry, the study of green, safe and effective bioactive feed additives can provide an effective way to achieve the goal of healthy aquaculture. Enzyme is a protein with special catalytic ability produced by living cells. It exists widely in various organisms and participates in the body and various biochemical reactions. The processed products of enzymes produced in living organisms are called enzyme preparations. In recent years, enzyme preparations have attracted widespread attention from the feed and aquaculture industries due to their environmental protection and safe use. Many studies have shown that adding enzyme preparations to feed can improve the utilization rate of feed for aquatic animals, reduce feed costs, and improve economic benefits. [0003] Nile...
