Problems solved by technology

[0003] Due to the high crude fiber content of crop straw, it cannot be decomposed by the digestive juice and enzymes of monogastric animals, and has few available nutrients and poor palatability, so it can only be partially used for feeding ruminants, which greatly restricts the utilization range of straw raw materials

Abstract

The invention discloses a method for producing antimicrobial-free feed through enzymosis and fermentation of straw. The method comprises the steps that corynebacterium glutamicum, candida tropicalis, bacillus natto, lactobacillus plantarum and aspergillus are cultured in liquid and prepared into a mixed bacterium solution according to proportion; corn or wheat straw and other raw materials are matched according to the proportion of a formula, calcium oxide is added, the mixture is put into an explode cylinder to carry out steam explosion; the materials obtained after the steam explosion are mixed with the mixed bacterium solution, and mixed materials are obtained after an enzyme preparation is added; the mixed materials are fed into a special modularization solid biological raw material continuous fermenting device to carry out enzymosis and fermentation, and the fermented materials are dried to obtain the antimicrobial-free feed. The method adopts a modularized automatic fermentation device, the exploded materials are mixed with a zymocyte solution and the enzyme preparation and then put into the automatic fermenting device to carry out enzymosis and biological fermentation, the requirement for automatic temperature control, humidity control and ventilation quantity control are met, the biological conversion rate is high, the fermentation period is short, losses are few, cost is low, and the mechanization and large-scale production demands can be met.

Description

technical field [0001] The invention relates to waste utilization of straw, in particular to a method for producing antibiotic-free feed through enzymolysis and fermentation of straw. Background technique [0002] With the rapid development of my country's animal husbandry, many feed materials in my country, especially protein resources, have experienced serious shortages. Therefore, solving the problem of shortage of feed raw materials has become the key or "bottleneck" restricting the sustainable development of animal husbandry in my country. On the other hand, my country's abundant unconventional feed raw material resources, such as crop straw, have not been effectively utilized. The total amount of various types of straw in my country is about 570 million tons every year. Except for a part used to generate biogas energy, most of them are burned on site, and the proportion used for feed raw materials is very small, resulting in serious waste. From the perspective of env...
