Integration processing method of high-efficient corn straw biological feed

Abstract

The invention discloses an integration processing method of a high-efficient corn straw biological feed, and belongs to the field of biological feeds. Corn straw is subjected to three-step fermentation, so that a superior microorganism coarse feed for ruminant animals, with high efficiency and low cost, is produced in a large-scale manner. The integration processing method comprises the following steps of firstly, based on the corn straw, performing high-efficient pure solid cultivation on a white rot fungus enzyme preparation, then converting the cultivated white rot fungus enzyme preparation in large inoculum amount to a first-stage fermentation medium of the corn straw, and besides, inoculating serial lignocelluloses degradation bacteria and candida utilis bacteria for synergistic rapid degradation and transformation; then adding bacillus and saccharomyces cerevisiae for second-stage fermentation; and using lactic acid bacteria for third-stage anaerobic fermentation so as to obtain finished products. The raw materials used by the integration processing method do not need to be sterilized, the finished products do not need to be dried, lysozymes are enriched, the cost is low, the lignin is notably reduced, and genuine protein is increased to 12% or above. The high-efficient corn straw biological feed can be used as a superior coarse feed and a protein grain feed for cattle and sheep, and the additive quantity can reach 60% or above; the additive quantity can also be about 10%, so that the high-efficient corn straw biological feed is used for simple stomach animals. The technique is high in scalability and integrity, and the economic and social benefits are notable.

Description

technical field [0001] The invention belongs to the field of biological feed, in particular to a novel microbial roughage with high efficiency and low cost based on corn yellow mature stalks as raw materials. Background technique [0002] Corn stalks are one of the most abundant straws in China. If they are used as energy-based materials such as power generation, biogas, gasification, and solidification molding, the economic benefits will be low. Straw ethanol, whose production cost is more than 7,000 yuan per ton, is not easy to produce without state subsidies. Profit; fertilization is actually a huge waste of resources; the total amount used for processing such as board is limited; compared with rice straw, wheat straw, etc., corn straw has better nutritional indicators, and the purchase price in many places is twice as low as that of wheat straw , corn stalks are a good way out for feed, but most of the harvested corn stalks are not processed and fed directly, which has d...

Problems solved by technology

[0008] In order to improve the degradation of lignin, some relatively scientific invention patents carry out co-fermentation of fiber degrading bacteria and white rot fungi, such as (103146606B) and (103549129B), the former uses Phanerochaete chrysosporium, Trichoderma, yeast, Bacillus subtilis Co-fermentation with lactic acid bacteria, straw aerobic fermentation and fermentation with anaerobic bacteria, but the slow growth of white rot fungus and the fast growth of Trichoderma lead to long aerobic fermentation time, high cost and easy to infect bacteria

The latter also uses the slow-growing Phanerochaete xanthophyllum, and co-fermentation with the fast-growing Trichoderma, Penicillium, and Aspergillus will cause inconsistencies, and the fermentation time will be long. The peak of lignin enzyme production is generally after 7 days, and the fermentation time also needs to be longer. After 10 days, the degradation of lignin is not significant under compaction and sealing, and the degradation rate is generally less than 20%.
