Multifunctional Bioactive Aquatic Feed Additive

Abstract

A multifunctional biologically active aquatic feed additive, which can be prepared according to the following process: (1) mix the materials; (2) add a small amount of 30-50°C warm water to the molasses to dissolve and mix, add complex bacteria and stir evenly, and place for 1 ~2 hours, then add remaining water to make composite bacteria solution; (3) add composite bacteria solution to the material and mix well, and naturally aerobic fermentation at room temperature for 50~60 hours; (4) dry at less than 60°C until Moisture ≤ 10%, crushed and packaged; the multifunctional biologically active aquatic feed additive provided by the invention has a probiotic content greater than 1012cfu / g, contains a large amount of chitooligosaccharides and seaweed oligosaccharides; contains a large amount of active small peptides; protease, lipase and amylase, etc. The production method has simple process, does not need special heat sterilization and fermentation equipment, has low energy consumption and short fermentation cycle.

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
