Embodiment 1

[0050] The present embodiment provides the method for preparing selenium-enriched fermented composition, and it comprises the steps:

[0051] (1) Preparation of selenium-enriched yeast culture solution: mix malt and water at a mass ratio (g:g) of 1:4, then heat-preserve and saccharify at 55°C for 4 hours, filter and boil the filtrate, and finally cool to room temperature and clarify; Add the pre-sterilized sodium selenite concentrated solution of 10% (wt) (100g wort adds 10g sodium selenite concentrated solution) to the solution, the concentration of this sodium selenite solution is 5mg / mL, insert and contain Saccharomyces cerevisiae and The mixed bacterial liquid of Lactobacillus acidophilus (the cell number ratio of Saccharomyces cerevisiae and Lactobacillus acidophilus is 2:1), the final concentration of Saccharomyces cerevisiae after inoculation is 2×10 10 individual / mL, the final concentration of Lactobacillus acidophilus was 1×10 10 individual / mL.

Abstract

The invention discloses a rich-selenium fermentation type composition, a preparation method, application and feed, and relates to the technical field of aquatic product feed. The rich-selenium fermentation type composition is prepared from rich-selenium yeast culture liquid and a plant leaf fermentation culture medium through mixing and fermentation, wherein the rich-selenium yeast culture liquidcontains brewer's yeast and lactobacillus acidophilus; the plant leaf fermentation culture medium contains plant leaf fermentation raw materials containing plant leaf powder; the plant leaf powder isprepared from horseradish tree leaves, ginkgo leaves and paper mulberry leaves through mixing and crushing. The rich-selenium fermentation type composition is used for replacing fish meal in conventional aquatic product feed; the cost is reduced; when the rich-selenium fermentation type composition is used for feeding fish bodies, the fish body growth function can be improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a selenium-enriched fermented composition, a preparation method, application and feed. Background technique [0002] At present, in addition to animal protein such as fish meal, bone meal, and silkworm chrysalis, the protein feed sources widely used in aquatic feed also include vegetable protein such as rapeseed meal, soybean meal, cottonseed meal, and secondary meal. In recent years, due to the serious shortage of protein feed resources and the high price, it has become the main restrictive factor for the development of aquaculture. In addition, the performance of existing aquafeeds in improving the growth function of fish still needs to be improved. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a selenium-enriched fermented composition, which can be used to replace fish...
