Abstract

The invention relates to a novel technology of enzymatic hydrolysis and fermentation synergy for whole corn silage and belongs to the field of feed processing. The novel technology of enzymatic hydrolysis and fermentation synergy for whole corn silage is provided through a synergetic technology of compound enzyme hydrolysis and two-step bio-fermentation by taking whole-plant corns as a raw material and alfalfa and algae as auxiliary materials, the key bottleneck in the traditional whole corn silage technology is solved, the feeding nutritive value of whole-plant silage corns is increased, and secondary fermentation is prevented. The novel technology has the advantages that through synergistic effect of the enzymolysis of compound enzyme and microbial fermentation, anti-nutritional factors in the raw materials such as corn straws are biologically degraded to form small molecular matters, and harmful matters such as phytic acid and the like are eliminated; and through the fermentation action of multiple lactobacillus, the quality and the nutritional components of a product are remarkably improved. The product is high in feeding nutritive value, has a better application prospect and has important significance of promoting development of grain, industrial and forage crops.

Description

technical field [0001] The invention relates to a new technology of enzymolysis and fermentation synergistic whole corn silage, which belongs to the field of feed processing. Background technique [0002] Although our country is a big agricultural country, we have a lot of people and little land, insufficient grain production, and a shortage of feed grain. Although the area of ​​grassland in my country is large, due to natural disasters and man-made disasters, the grassland has been seriously degraded, and the shortage of forage grass has seriously restricted the development of animal husbandry. With the development of my country's animal husbandry and breeding industry, according to the current grain production level and animal feed conversion rate, the feed gap in my country will reach more than 120 million tons by 2020, and the problem of feed sources is becoming increasingly tight. Develop new feed resources. In 2015, the No. 1 Central Document mentioned that “to speed ...
