Problems solved by technology

[0002] Rapeseed meal, also known as rapeseed meal, is a by-product of oil extraction from rapeseed. The crude protein content of rapeseed meal is about 37%. It is an important protein feed resource, rich in lysine and trace elements, including calcium, The content of selenium, iron, magnesium, manganese and zinc is higher than that of soybean meal, and the content of phosphorus is twice that of soybean meal. At the same time, it is also rich in sulfur-containing amino acids, which are the nutrients that soybean meal lacks, but the crude fiber content of rapeseed meal is higher than that of soybean meal. High, some up to 18% or more; more than 60% of the total phosphorus content is phytate phosphorus, which is not conducive to absorption and utilization
In addition, rapeseed meal also contains toxic substances and anti-nutritional factors such as glucosinolates, tannins, sinapine, saponin, etc., which not only affect its nutritional value, but also endanger the he

Abstract

The present invention discloses a rapeseed meal enzyme-linked micro-ecological preparation and a solid fermentation method of rapeseed meal. The preparation comprises ingredients: xylanase, beta-glucanase, galactosidase, beta-mannanase, cellulase, phytase, acid protease, neutral protease, papain, alkaline protease, amylase, lactic acid bacteria, bacillus, yeasts, starch and polysaccharides. The preparation is prepared by mixing the various enzyme preparations with the fermentation micro-organisms, reduces the use of an acidifier, reduces production costs, and at the same time enhances decomposition and detoxification effects of the preparation. A produced fermented rapeseed meal feed product is rich in 3-15% of lactic acid; glucosinolate is reduced by 80% or more and toxic effects on livestock and poultry are significantly reduced; crude proteins are increased by 1-2% and a consumption of non-protein materials is ensured; a small peptide content is increased to 15-25% and utilization of animals for feed proteins is effectively improved; and bitter substances in the rapeseed meal are effectively removed and a tannin degradation rate is 60% or more.
