Production method of biological straw forage

Abstract

Disclosed is a production method of biological straw forage. The production method is characterized by comprising: pulverizing straw; adding auxiliary materials for mixing based on a weight ratio of 0.5-2% of urea and 1-3% of wheat bran; allowing the water content of the raw materials to be 50-60%; performing stewing; performing cooling to a certain temperature; inoculating, according to a weight ratio, 0.1-0.5% of mould fermentation yeast and 0.5-1% of a liquid leavening agent, wherein the liquid leavening agent is a mixed preparation of three kinds of bacteria of microzyme, bacillus, and lactic acid bacteria according to a volume ratio of 1:0.5:1; performing moisture preservation and fermentation at 25-30 DEG C for 36-72 h; and performing drying at 40-50 DEG C to produce the product.

Description

technical field [0001] The invention relates to a biological straw feed, in particular to a production method of the biological straw feed. Background technique [0002] Straw resources are abundant. There are about 600 million tons of straw as a by-product of crops in my country every year, of which more than 480 million tons can be collected and utilized. However, only about 45% of the straw is used as animal feed, industrial raw materials, and fertilizer. The rest of the straw is It is inefficiently used as a living fuel, or even discarded and burned on site, causing environmental pollution. my country's aquaculture industry needs about 2 billion tons of concentrated feed per year, but the actual supply is only about 1.5 billion tons, with a gap of 500 million tons. Protein feed is seriously insufficient. Our country needs 10 million tons of protein feed every year, but the actual output is only about 90,000 tons. The contradiction between supply and demand is very promin...
