Feed for improving meat quality of fish and use thereof

Abstract

The invention discloses a feed for improving meat quality of fish and use thereof. The feed comprises the following raw materials in part by weight: 60 to 80 parts of broad beans and dehulled broad beans, 2 to 6 parts of bean pulp, 6 to 13 parts of cottonseed meal and 6 to 12 parts of rapeseed meal. The feed disclosed in the invention can overcome the drawbacks of looseness of meat quality of grass carps, low freshness of muscle and poor mouthfeel under concentrated breeding, effectively improve the bending strength of the muscle fibril and diameter of muscle fibers of grass carps, improve the compactness and toughness of the meat of the grass carps, improve the delicious amino acid content in muscle and greatly lower breeding cost of grass carps and is suitable for industrial production.

Description

Technical field [0001] The invention relates to a feed, in particular to a feed for improving fish meat quality. At the same time, the invention also relates to an application method of the feed, which belongs to the technical field of aquatic feed. Background technique [0002] Grass carp (Ctenopharyngodon idellus) is one of the main species of freshwater aquaculture in my country. It is widely distributed in the rivers of the northeast, east, central and southern regions of China. It grows fast, produces high yields, and is loved by consumers for its good meat quality. Become the best among conventional breeding species. However, for a long time, people have believed that grass carp is a typical herbivorous fish. It is fed with green fodder, dry grass, aquatic grass and crop straw. Because these plant-based feeds have high crude fiber content and low protein and other effective nutrients, grass carp is not easy to digest and absorb after ingesting. After the excrement of grass...

AI Technical Summary

Problems solved by technology

[0004] At present, with the popularization of intensive aquaculture, domestic grass carp feed is basically based on compound feed, and most of the raw materials use soybean meal, cotton meal, and rapeseed meal as the main protein source, resulting in soft meat, high water content, and muscle. The freshness is not enough, the taste and flavor are obviously reduced, the shreds are brittle, and the cooking is easy to rot, which affects the sustainable development of grass carp farming
