Black carp feed capable of reducing incidence of diseases

Abstract

The invention relates to the technical field of aquaculture, and specifically relates to black carp feed capable of reducing incidence of diseases. The feed is prepared by the following raw materials by weight: 50-55 parts of corn, 20-25 parts of soybean meal, 18-20 parts of rice bran, 12-15 parts of fried pea meal, 2-3 parts of freshwater mussel meat meal, 2-3 parts of dry red date powder, 4-5 parts of Chinese chive seeds, 4-5 parts of onions, 8-10 parts of sweet potato seedlings, 8-10 parts of fermented soybeans, 5-8 parts of dried yeast powder, 4-5 parts of silkworm chrysalis meal, 4-5 parts of freshwater mussel meat meal, 5-6parts of soybean meal, 3-4 parts of earthworm meal, a proper amount of salt and 4-5 parts of a phagostimulant. The black carp feed prepared by the invention takes full consideration of feeding characteristics of the black feed, the raw materials such as the freshwater mussel meat meal, the fermented soybeans and the silkworm chrysalis meal are added on basis of basic raw materials, so that nutrition of the feed is supplemented; and palatability of the feed is improved. The raw materials such as Chinese chive seeds enhance disease-resistant and antibacterial capacities of the black carp, so that probability of diseases is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a herring feed with reduced morbidity 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 t...
