Artificial compound feed for improving meat quality of turbots

Abstract

The invention aims to provide an artificial compound feed for improving the meat quality of turbots. The artificial compound feed provided by the invention respectively comprises the following components in percentage by weight: 35-60% of brown fishmeal, 15-30% of wheat meal, 1-5% of beer yeast, 0.5-3% of compound vitamins, 0.5-3% of compound mineral elements, 0.05-3% of beta-hydroxyl-beta-methyl calcium butyrate, 2-6% of fish oil, 1-5% of soya bean lecithin, and 0.05-1% of choline chloride. The artificial compound feed provided by the invention is capable of increasing the growth speed of turbots, reducing the body fat level, increasing the hardness, the chewiness and the elasticity of turbots, improving the mouth feel of turbots, increasing the number of unit area turbot muscle fibres and reducing the cross section area of the muscle fibres; therefore, the meat quality is more delicate and the elasticity is achieved; furthermore, the survival rate, the feeding rate, the feed efficiency, the hepatosmatic index, the organ-body ratio and the fatness of turbots are not influenced; and the ash content, the water content and the protein components of turbot bodies are not influenced.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and in particular relates to an artificial compound feed for improving the quality of turbot fish meat. Background technique [0002] my country is a large aquaculture country in the world, and its aquaculture output ranks first in the world. With the development of the mariculture industry and the improvement of people's living standards, marine fish has increasingly become the first choice of nutritious food for consumers, and people have begun to pay more attention to indicators such as the quality and taste of fish meat. Turbot is a representative species of northern mariculture. It is a typical carnivorous fish with tender and delicious meat, high nutritional value and fast growth. It is a valuable cold-water economic fish and has great economic and social benefits. However, due to the existing feed formula system, high-density breeding and inbreeding that have lasted for many year...

AI Technical Summary

Problems solved by technology

However, due to the existing feed formula system, high-density breeding and inbreeding that have lasted for many years, the quality of turbot fish meat has deteriorated, the taste has deteriorated, and the growth rate has decreased, which seriously hinders the development of the turbot industry.
