Fully-cooked puffed slowly-settling mixed feed for Micropterus salmoides

Abstract

The invention discloses a fully-cooked puffed slowly-settling mixed feed for Micropterus salmoides. The mixed feed is prepared from, by weight, 20.0 to 50.0 parts of Peru fish meal, 10.0 to 25.0 parts of soybean meal, 5.0 to 15.0 parts of fermented soybean meal, 2.0 to 8.0 parts of rapeseed meal, 2.0 to 10.0 parts of cottonseed meal, 2 to 10.0 parts of peanut meal, 1.0 to 5.0 parts of DDGS, 8.0 to 15.0 parts of high gluten flour, 1.0 to 4.0 parts of brewer's yeast, 1.0 to 3.0 parts of soya lecithin, 1.0 to 3.0 parts of soybean oil, 1.0 to 3.0 parts of fish oil, 0.1 to 0.5 part of choline chloride, 1.0 to 3.0 parts of squid paste, 1.0 to 2.0 parts of calcium dihydrogen phosphate, 0.5 to 2.0 parts of zeolite powder, 0.1 to 0.3 part of a mildew inhibitor, 0 to 0.3 part of lysine, 0 to 0.1 part of methionine, 0.04 to 0.1 part of bile acid, 0.05 to 0.2 part of VC phosphate, 0.2 to 0.5 part of a vitamin premix and 1.0 to 2.0 parts of a trace element premix. Through optimization of a formula for the mixed feed, and the feed is greatly lowered in cost, comprehensive in nutrients, good in feeding attraction and palatability and low in bait coefficient and can promote growth of Micropterus salmoides; thus, the growing ability of Micropterus salmoides is promoted, culturing cost is reduced, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a California perch fully matured puffed slow-settling compound feed. Background technique [0002] California perch is a typical euthermic carnivorous freshwater fish. It has been favored by many consumers because of its firm meat and delicate meat taste. Therefore, the breeding volume has increased year by year, and the output has repeatedly hit new highs. Secondly, at present, the extruded floating feed is gradually replacing chilled fresh. When California perch likes to live in the middle and lower water bodies, it has the ability to avoid light when eating, and the California perch has poor tolerance to the peak, and it is difficult to digest starch. Excessive starch content will lead to hepatomegaly , and California perch likes to eat live bait, fierce competition for food, uneven food intake can easily lead to large individual differences, uneven finished products ...

AI Technical Summary

Problems solved by technology

Secondly, the current extruded floating feed is gradually replacing chilled fresh. When California perch likes to live in the middle and lower water bodies, it has the ability to avoid light when eating, and the California perch has poor tolerance to the peak, and it is difficult to digest starch. Excessive starch content will lead to hepatomegaly , and California perch likes to eat live bait, fierce competition when eating, uneven feeding can easily lead to problems such as large individual differences, uneven finished products and specifications, and low commodity rate

In addition, the extruded floating feed cannot simulate the dynamic and slow sinking of live bait. Therefore, the extruded floating feed seriously restricts the promotion and breeding of California perch feed.
