Environment-friendly feed for longsnout catfish at hibernation period

Abstract

The invention discloses environment-friendly feed for longsnout catfish at a hibernation period. The environment-friendly feed is prepared from the following raw materials in parts by weight: 10-25 parts of cicada pupa powder, 12-25 parts of cottonseed meal, 10-20 parts of rapeseed meal, 8-16 parts of soybean meal, 5-15 parts of rice bran, 8-16 parts of corn protein powder, 5-15 parts of fish bone meal, 5-15 parts of vinasse, 10-20 parts of flour, 5-15 parts of modified corn prolamine, 5-15 parts of fish oil, 0.5-1.5 parts of choline chloride, 1-3 parts of sodium carboxymethyl cellulose, 0.15-0.25 part of crystalline lysine, 0.3-0.8 part of methionine, 0.5-2.5 parts of monocalcium phosphate, 0.5-1.5 parts of beta-glucan, 0.5-1.5 parts of nicotinic acid, 0.2-0.8 part of inositol, 0.1-0.5 part of folic acid, 1-3 parts of zeolite powder and 1-3 parts of a premix. The environment-friendly feed can be used for the hibernation period of the longsnout catfish; the protein and energy demanding of the longsnout catfish is guaranteed and the intestinal environment can be improved; and the absorption conversion rate of the feed is extremely high, the excrement of the longsnout catfish is less and the environment pollution is small.

Description

technical field [0001] The invention relates to the technical field of catfish feed, in particular to an environment-friendly feed for catfish in winter. Background technique [0002] There are many catfish feed manufacturers on the market, most of which are feeds for the grow-out stage. There are few feed products for catfish winter health care. When the fish are overwintered, they are thin, lose weight, and have poor body shape, which directly affects the economic benefits of farmers. Generally, farmers often increase the amount of feed input, which not only leads to a lot of fish excrement, but also pollutes the water environment. The absorption conversion rate is also not high. Contents of the invention [0003] The invention proposes an environmentally friendly feed for catfish in the winter period, which can be used for catfish in the winter period. While ensuring the protein and energy requirements of catfish, the intestinal environment can be improved, the feed ab...
