Black carp feed rich in nutrition

Abstract

The invention discloses a black carp feed rich in nutrition. The black carp feed comprises the following raw materials in parts by weight: 30-45 parts of peanut powder, 15-25 parts of oat, 20-32 partsof sorghum, 5-12 parts of molasses, 5-18 parts of rapeseed meal, 8-18 parts of chrysanthemum flower meal, 4-16 parts of paper mulberry powder, 7-12 parts of sweet potato leaves, 1-4 parts of mulberryleaves, 1-2 parts of gravel, 0.5-1.2 parts of dicalcium phosphate, 0.1-0.6 part of lanthanum malate, 0.02-0.05 part of complex enzymes, 0.01-0.04 part of phytase and 1-2 parts of a premix. The blackcarp feed disclosed by the invention is balanced and rich in nutrients, can enhance the capacity of black carps for resisting diseases and resisting bacteria, is easy for the black carps to eat and ishigh in digestion degree.

Description

technical field [0001] The invention relates to the technical field of herring feed, in particular to a nutrient-rich herring feed. Background technique [0002] Herring is one of the four major fish in my country. Most of the aquaculture industry in my country is in the environment of still water ponds. High-density aquaculture causes a large amount of aquatic animal excrement, residual bait, and disinfectants to settle at the bottom of the water, and then decomposes to release a large amount of harmful substances. The water quality environment is deteriorating, the breeding density is increasing, the water environment is deteriorating, and the breeding diseases are also increasing. Many diseases have seriously threatened the breeding benefits, and the loss of feed in the water and the accumulation of excreta have become the main pollution sources of the water body, leading to the deterioration of water quality. Massive breeding, decreased survival rate, increased dosage of m...

[0002] Herring is one of the four major fish in my country. Most of the aquaculture industry in my country is in the environment of still water ponds. High-density aquaculture causes a large amount of aquatic animal excrement, residual bait, and disinfectants to settle at the bottom of the water, and then decomposes to release a large amount of harmful substances. The water quality environment is deteriorating, the breeding density is increasing, the water environment is deteriorating, and the breeding diseases are also increasing. Many diseases have seriously threatened the breeding benefits, and the loss of feed in the water and the accumulation of excreta have become the main pollution sources of the water body, leading to the deterioration of water quality. Large-scale breeding, decreased survival rate, increased dosage of medication, frequent water changes, and thus increased breeding costs. How to prepare a herring feed that is rich in nutrients, easy to eat by herring, and has a high degree of digestion has become a technical problem that needs to be solved at present.
