Multifunctional biology aquatic feedstuff additive

Abstract

The invention provides a multifunctional biological activity aquatic product feed additive, which can be prepared by following steps: (1) uniformly mixing material; (2) adding a little warm water of 30-50 DEG C into molasses and uniformly mixing, adding composite bacterium and uniformly mixing, placing for 1-2 hours, and adding residual water to prepare composite bacteria liquid; (3) adding the composite bacteria liquid into the material, uniformly mixing, and carrying natural aerobic fermentation for 50-60 hours at room temperature; (4) drying the mixture until moisture is less than or equal to 10% under temperature less than 60 DEG C, and grinding package. Content of the multifunctional biological activity aquatic product feed additive provided by the present invention is more than 10<12>cfu / g, the aquatic product feed additive contains a large amount of chitooligosaccharides, alga oligosaccharides and active small peptide, and simultaneously contains a plurality of protease, lipase and amylase. The invention has advantages of simple production method, no need of special heating sterilization and fermentation equipment, less energy consumption and short fermentation period.

Description

technical field [0001] The invention relates to an aquatic feed additive, in particular to a multifunctional bioactive aquatic feed additive. Background technique [0002] Existing livestock, poultry and aquatic animal feeds are generally composed of grain, animal protein, appropriate amount of amino acids and trace elements. These feeds have a short shelf life and are susceptible to the invasion and reproduction of harmful bacteria in high temperature and humid environments, leading to mold and deterioration. For example, if you add too much food at one time, the feed will easily deteriorate when the livestock and poultry can’t finish it. It is especially difficult to solve the problem of water quality deterioration when aquatic animals are raised. Feces and residual feed promote the growth of spoilage bacteria, reduce the dissolved oxygen coefficient of the water body and cause a large number of anoxic deaths of fish and shrimp. In order to solve this problem, many aquacul...

Disclosed as Chinese patent application CN1146865A (application number 96109527.X, open date on April 9th, 1997) is a micro-ecological freshwater fish feed, which is a semi-finished product by three micro-ecological feed raw materials, mainly including the use of probiotic bacteria to treat animals. Animal active protein powder fermented from a mixture based on protein raw materials; photosynthetic probiotic yeast fermented from plant protein raw materials with photosynthetic bacteria, Bacillus cereus and certain yeasts; and Candida tropicalis and some probiotics Soil feed fermented from pure and non-polluted soil and other raw materials of bacteria, although it has achieved effects such as improving feed digestion and absorption rate and promoting growth, but there are still complex production processes, involving many strains, and high cost, especially the used Active bacteria have strict requirements on fermentation temperature and other issues
