Under-excretion wintering feed for leiocassis longirostris

Abstract

The invention discloses an under-excretion wintering feed for leiocassis longirostris. The under-excretion wintering feed is prepared from the following raw materials in parts by weight: 20 to 40 parts of cicada pupa powder, 10 to 30 parts of cottonseed meal, 5 to 18 parts of rapeseed meal, 10 to 20 parts of soya bean meal, 2 to 10 parts of bloodworm, 10 to 25 parts of corn protamine, 10 to 20 parts of shrimp meal, 10 to 20 parts of fishbone meal, 5 to 12 parts of flour, 2 to 12 parts of modified zein, 3 to 10 parts of colza oil, 1 to 3 parts of choline chloride, 1 to 5 parts of dextrin, 0.1 to 0.6 part of crystalline lysine, 0.2 to 0.7 part of methionine, 1 to 5 parts of monocalcium phosphate, 1 to 2 parts of beta-glucan, 0.1 to 0.5 part of nicotinic acid, 0.25 to 0.78 part of inositol, 1 to 2 parts of folic acid, 2 to 6 parts of zeolite powder and 1 to 2 parts of premix. The under-excretion wintering feed can be used in a wintering period of the leiocassis longirostris, the protein and energy requirements of the leiocassis longirostris are satisfied, additionally, the intestinal environment can be improved, the absorption and conversion rate of the feed is extremely high, the excreta of the leiocassis longirostris is less, and the environmental pollution is less.

Description

technical field

[0001] The invention relates to the technical field of catfish feed, in particular to a low-excretion winter feed for catfish. 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.
