Grass carp puffed feed for reducing mortality in high temperature season and preparation method thereof

Abstract

The present invention provides a grass carp puffed feed for reducing mortality in high temperature season. The grass carp puffed feed comprises 30 parts of imported fish meal, 380 parts of soybean meal, 40 parts of corn protein powder, 55 parts of low-erucic-acid and low-glucosinolate rapeseed meal, 150 parts of wheat middling, 200 parts of flour, 23 parts of phospholipid powder, 22 parts of soybean oil, 5 parts of calcium carbonate, 1 part of edible salt, 2 parts of calcium dihydrogen phosphate, 2 parts of choline chloride, 3 parts of lysine, 2 parts of methionine, 2 parts of vitamin C, 30 parts of zeolite powder, 3 parts of a multivitamin mixture, 2 parts of a mineral trace element mixture and 48 parts of a traditional Chinese medicine additive. Honeysuckle, lotus leaves and licorice have effects on clearing away heat, removing toxins, eliminating heat and reducing dampness, and have a very good summer-heating reducing function for grass carps in high temperature. Wrinkled gianthyssop herb, purple perilla and poria cocos improve a gastrointestinal function of the grass carps and promote effective absorption of nutrients. Radix codonopsis, Chinese angelica, white atractylodes rhizome, fructus psoraleae, fiveleaf gynostemma herb and dandelion enhance the immunity of the grass carps, reduce incidence of the grass carps, and thus reduce mortality.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to an extruded grass carp feed for reducing mortality in high temperature seasons and a preparation method thereof. Background technique [0002] Grass carp is the main freshwater fish farming object in China because of its rapid growth and wide source of feed. According to the statistics of "China Fishery Yearbook (2012)", the national grass carp farming output has reached more than 4.4 million tons, accounting for 1% of the total freshwater fish farming output. / 4 or so. In recent years, due to the substantial increase in production costs such as feed, rent, seedlings, medicines, and wages, farmers have had to increase breeding production by increasing stocking density in order to balance the ever-increasing breeding costs. However, the continuous increase in stocking density and production has resulted in the continuous compression of the water body space in which fish per kilogram live...

Problems solved by technology

[0003] The current grass carp feed is for the purpose of promoting growth. In the high temperature season, it is prone to frequent diseases, death by dragging the net, and inability to transport. The present invention aims at appealing to the situation and invents a grass carp puffed feed that reduces the mortality rate in high temperature seasons.
