Black carp feed capable of promoting growth

Abstract

The invention relates to the technical field of aquaculture, and specifically relates to a black carp feed capable of promoting growth. The feed is prepared by the following raw materials by weight: 45-50 parts of sweet corn flour, 20-25 parts of rye bran, 10-12 parts of alfalfa meal, 12-15 parts of tofu dregs, 12-15 parts of wheat middlings, 3-4 parts of calcium hydrophosphate, 4-5 parts of escargot meal, 4-5 parts of chicken intestinal meal, 4-5 parts of snail meal, 5-6 parts of sudan grass, 8-10 parts of yellow wine lees, 8-10 parts of duckweed meal, 2-3 parts of garlic powder, a proper amount of salt and 4-5 parts of a phagostimulant. The black carp feed prepared by the invention takes full consideration of the feeding characteristics of the black carp, raw materials such as the escargot meal, the chicken intestinal meal and the snail meal are added in basic raw materials, so that nutrition of the feed is supplemented; and palatability of the feed is improved. Feed consumption of the black carp is increased; the growth and development of the black carp are rapid; the weight is increased obviously; and culture benefits are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a growth-promoting herring feed and a preparation method thereof. Background technique [0002] Herring is one of the four major freshwater fishes in my country. Its meat is tender, rich in nutrients, and contains precious trace elements. It has nourishing, strengthening, and anti-cancer therapeutic effects. It is widely welcomed by consumers. Herring farming has also transitioned from traditional pond stocking to large-scale cage farming. However, in the process of intensive farming, the feeding and management of herring is particularly important. Most of the existing herring feeds have nutritional imbalances and excessive addition of hormone drugs. Many problems, such as high heavy metal content, lead to various diseases and drug residues in herrings, which seriously affect the breeding benefits of herrings. Therefore, in order to improve the breeding benefits, change the fee...

Most of the existing herring feeds have nutritional imbalances and excessive addition of hormone drugs. Many problems, such as high heavy metal content, lead to various diseases and drug residues in herrings, which seriously affect the breeding benefits of herrings. Therefore, in order to improve the breeding benefits, change the feed formula, ensure balanced nutrition, and promote the growth and development of herrings. solution
