Problems solved by technology

Directly feeding broad beans needs to be soaked and crushed, which requires a lot of labor, far less convenient than pellet feed, and the cost is high. The growth rate of tilapia becomes slow, which seriously pollutes water quality, leads to eutrophication of waters, and the hazards of fish diseases increase significantly.

Abstract

The invention relates to the field of aquatic feed, and specifically provides a special compound feed for improving tilapia meat quality and a preparation method thereof. The parts by weight of each component of the feed formula are: 40-70 parts of broad beans, 2-5 parts of fish meal, 7-12 parts of bran, 9-19 parts of rapeseed meal, 8-19 parts of peanut meal, 1-2 parts of fish oil 0.3-0.5 parts of betaine, 0.4-0.6 parts of choline chloride, 0.6-0.8 parts of calcium dihydrogen phosphate, 0.10-0.13 parts of methionine, 0.06-0.1 parts of enzyme preparations, 0.02-0.03 parts of allicin, and 0.4 parts of multivitamins -0.6 parts, 1.0-1.2 parts of compound mineral salt. The invention also provides a preparation method of the above-mentioned feed. The feed of the invention can improve the muscle quality of the tilapia, making the meat firm and crisp; improves the growth performance of the tilapia, reduces water pollution, reduces production costs, and has remarkable economic and social benefits.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a special compound feed for improving tilapia meat quality and a preparation method thereof. Background technique [0002] Tilapia is an important freshwater economic fish in my country, and its aquaculture and export production has been ranking first in the world in recent years. With the increase of intensive farming, while the output of tilapia farming continues to increase, the meat quality generally declines, and the elasticity and chewiness are poor. Unreasonable feeding methods have caused serious pollution to the farming ecological environment, making aquatic products The quality drops further. [0003] With the improvement of living standards, people's eating habits are changing, and higher requirements have been put forward for the meat quality of farmed fish. Feeding broad beans can change the meat quality of grass carp, tilapia and other fish and make them cr...
