Preparation method for selenium-rich aquatic animal nutrient

Abstract

The invention relates to a preparation method for a selenium-rich aquatic animal nutrient. The formula (in percentage by weight) consists of 0.8 to 1.8 percent of aspartic acid, 0.9 to 1.9 percent ofdl-Alpha-tocopheryl acetate, 1.2 to 2.2 percent of calcium gluconate, 1.5 to 2.5 percent of bifidobacterium longum, 0.2 to 1.2 percent of ammonium chloride, 1 to 2 percent of sea cucumber extract, 2.5to 3.6 percent of lactobacillus, 2.3 to 3.3 percent of sorbitan monooleate, 2.6 to 3.6 percent of inonotus obliquus extract, 2.2 to 3.2 percent of proteus hauser, 1.7 to 2.7 percent of sodium butyrate, 1.9 to 2.8 percent of protease, 0.3 to 1.3 percent of chondroitin sulfate sodium salt, 0.1 to 1.1 percent of ammonium sulfite, 0.6 to 1.6 percent of sodium carboxymethylcellulose, 0.7 to 1.5 percent of vitamin C, 0.5 to 1.6 percent of potassium sulfate, 1.2 to 2.1 percent of trehalose, 1.1 to 2.2 percent of probiotics, 0.2 to 1.3 percent of selenium yeast and 76.5 to 56.5 percent of water. Theinvention can effectively enable the growth performance of aquatic animals to reach an optimal level, and the specific growth rate, the weight gain rate, the feed utilization rate, the protein utilization rate and the feed protein deposition rate can all reach the maximum.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and specifically relates to a method for preparing selenium-enriched aquatic animal nutrients using natural organisms, animal and plant extracts, yeast selenium, microbial bacteria, vitamins, and mineral elements as basic raw materials. Background technique [0002] The global aquaculture industry is increasing at a rate of 24% every year. It is currently 35 billion US dollars per year and will reach 49 billion US dollars in 2020. The antibiotics used by aquatic animals are mainly excreted with feces and urine in the form of prototypes or metabolites. In the environment, it has adverse effects on the ecological environment such as the environment and water bodies, and has a toxic effect on the ecological environment through the food chain. After a large amount of antibiotics are ingested, the immunity of aquatic animals will be reduced, and pathogenic bacteria will take advantage of it to caus...
