Method for preparing composite micro-ecological enzyme for feeding the ruminant by using disused mushroom dregs

Abstract

Waste mushroom growing medium after picking up mushroom is compounded with crushed crop stalk, and the mixture is moistened with water, inoculated with 2-8 % enzyme producing composite microbial preparation and fermented at certain temperature for 3-15 days to convert all the material into semi-solid as composite micro ecological enzyme preparation for ruminant. After finishing the fermentation, the product is detected to possess total microbe amount not less than 3.0E10 CFU / g, cellulase FPA not less than 400 U / g, proteinase not less than 180 U / g, lipase not less than 240 U / g and amylase not less than 200 U / g.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a compound for feeding ruminants with micro-ecological effects, which uses waste mushroom dregs produced after the production of edible fungi as the main raw material and is artificially domesticated through the action of a variety of beneficial enzyme-producing microorganisms. A production method of a microecological enzyme preparation, which is applied to the production of ruminants. Background technique [0002] With the entry of WTO, the value of conventional agricultural products has depreciated, resulting in increased production but not income for farmers. The animal husbandry production has shown broad development prospects, especially the economic benefits of raising ruminants such as cattle and sheep are more prominent. Although the business opportunities and potential of the cattle and sheep breeding industry are huge, with the implementation of my country's "...

AI Technical Summary

Problems solved by technology

[0007] The annual production of single-enzyme micro-ecological feed enzyme preparations in my country is less than 1000T (mainly used for monogastric animals), and the comprehensive enzyme activity is low, the enzyme activity is unstable, and the price is high (100,000 to 120,000 yuan / ton)

If the price of compound microecological feed enzyme preparation is 40,000 to 60,000 yuan / ton, my country will need hundreds of thousands of tons per year. At present, the strains officially approved for the production of enzyme preparations for monogastric animals mainly include Bacillus cereus and Bacillus subtilis , Lactobacillus, Lactococcus, etc. Most of the strains produced are single strains, and most of them are used as therapeutic agents for preventing and treating diarrhea in livestock and poultry. Only a few feed companies are in trial production, and the comprehensive enzyme activity is not high

However, the microecological enzyme preparation in the field of ruminant breeding has not yet been applied and developed.
