Biological feed formula for litopenaeus vannamei and ultralow temperature expanding preparation method thereof

Abstract

The invention discloses a biological feed formula for litopenaeus vannamei and an ultralow temperature expanding preparation method thereof. The biological feed formula for litopenaeus vannamei is characterized by consisting of the following components in percentage by weight: 18-25% of expanded bean pulp, 13-16% of cooked bean flour, 10-15% of fish meal, 6-9% of kelp powder, 12-18% of flour, 8-10% of corn flour, 2-4% of soybean protein concentrate, 2-3% of bentonite, 0.5-1% of yeast for aquiculture, 1-2% of fish oil, 0.5-1% of vitamin complex, 0.5-1% of lactobacillus, 0.5-1% of bacillus, 0.5-1% of oligosaccharide, 0.2-0.5% of squid paste and 0.1-0.3% of an immunity-enhancing preparation. According to the ultralow temperature expanding preparation method, the aging and drying temperatures are not higher than 70 DEG C, and the ultralow temperature expanding temperature is not higher than 60 DEG C. The feed effectively reserves the activity of probiotics, improves the intestinal florae of litopenaeus vannamei, is favorable for sufficient digestion and absorption of the feed by the litopenaeus vannamei, improves the growth rate of the shrimps, reduces the incidence of disease, and also can effectively improve the water quality and stabilize the algal facies.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a feed formula for Penaeus vannamei used for Penaeus vannamei and an ultra-low temperature puffing preparation method thereof. Background technique [0002] In 2016, the global per capita annual consumption of aquatic products reached 20.5 kg, an increase of 16.5% compared with 17.6 kg in 2006. With the growth of population and the improvement of living standards and the per capita consumption remains unchanged, it is estimated that by 2030, the aquaculture output will Need to increase by 50 million tons. my country is the only country in the world where the total amount of aquacultured aquatic products exceeds the total amount of fishing. It is the largest country in the world for aquacultured aquatic products, with a total of more than 45 million tons of aquacultured aquatic products, accounting for about 70% of the world's total . Because of its advantages such as wide range o...

Problems solved by technology

At present, there are many kinds of feeds for Penaeus vannamei in the market, but they are also chaotic, and there are many misunderstandings in the development

First, the excessive pursuit of high-protein feeds leads to slow development of shrimp bodies, decreased immunity, and decreased survival rate; second, excessive addition of food attractants; third, the lack of functional feeds for the current high-density farming model
