Biological fermentation type functional feed for bighead carp

Abstract

The invention provides biological fermentation type functional feed for bighead carp. The feed is mainly prepared from components in parts by weight as follows: 30-70 parts of fish meal, 300-600 partsof distillers' grains, 200-400 parts of soybean meal, 50-100 parts of bran, 70-130 parts of rice bran and 15-35 parts of a premix. The premix comprises a fermenting agent and components capable of promoting bighead carp culture such as multi-vitamins for fish and compound ore elements for fish, and the fermenting agent comprises saccharomyces cerevisiae, lactobacillus plantarum, bacillus coagulans, enterococcus faecalis and clostridium butyricum. The invention also provides a preparation method of the biological fermentation type functional feed for bighead carp. The method mainly comprises the following steps: uniformly mixing all the components, directly placing the mixture in a net bag with a respiratory membrane, and fermenting the mixture for 7-10 days to obtain the feed. The biological fermentation type functional feed for bighead carp is simple to prepare, not high in equipment requirement, high in operability and easy to promote and use in large-scale farms or aquaculture cooperatives.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a biologically fermented functional bighead carp feed. Background technique [0002] Bighead carp (scientific name: Aristichthys nobilis) is also called silver carp, fat head fish, baotou fish, big head carp, black carp, black carp, and male carp. It is a type of freshwater fish. Known as "water scavenger", it is one of the four major fishes in China. According to the preliminary statistics of the "2015 China Fishery Statistical Yearbook", the total output of bighead carp in the country is about 3.203 million tons, an increase of about 6.2% compared with 2013, and the output is second only to grass carp and silver carp. Bighead carp has a large and broad head, thin and dense body scales, dark brown back with regular small black spots, dark brown side with brown or yellow flower spots, grayish white belly. Bighead carp is docile by nature, moves slowly, and inhabits the middle and up...

AI Technical Summary

Problems solved by technology

Powder feeding has the disadvantages of low feeding efficiency of bighead carp and water quality is easy to deteriorate, and the cost of breeding is high; the processing cost of small particle puffed feed is between 600-700 yuan / ton, which is relatively high, and the high temperature process of puffing has a great impact on feed Sensitive nutritional factors in the medium have great destructive power, high production cost and low conversion rate

[0005] As the scale of bighead carp farming continues to expand and the stocking density continues to increase, there are few special compound feeds for bighead carp farming on the market, which are prone to improper feed selection, overfeeding of feed, and overfilling of low-quality feed, resulting in poor growth performance of bighead carp. decline, cause nutritional diseases, and eutrophication of aquaculture water
