Production method and application of stalk fermentation feed

Abstract

The invention provides a production method and application of stalk fermentation feed, and relates to the field of stalk comprehensive utilization and fermentation feed production. The method solves the problems that during the existing stalk feed treatment, low-moisture anaerobic fermentation is used, so that vacuum pumping treatment is needed; the process is complicated; the cost is high; the fermentation is unthorough; metabolites are few; drying treatment is needed, so that the energy consumption is increased; the viable count is reduced, so that the poor application effect is caused. A bag pressing fermentation process is used; through multi-layer stacking, air is extruded through the weight of the materials; the anaerobic fermentation requirements can be met without vacuum suction. The material water content reaches 58 to 65 percent, so that the stalks can be sufficiently fermented; a great number of probiotics and metabolites can be generated; the nutrition value of the stalks can be greatly improved; the acidity is low and reaches 3.5 to 4.5; the shelf life is more than 90 days; the feeding in a way of being matched with the existing feed system can be realized without drying; the cost is reduced; the efficiency is improved. The feed is mainly used for feeding monogastric animals such as pigs and poultry. The production method and the application are applied to the field of feed.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of straw and the field of fermented feed production, in particular to a high-efficiency, low-cost, and suitable for large-scale industrial production of straw bio-fermented feed production process and application. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of a crop after the seeds are harvested. Crop straw contains nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a renewable biological resource with multiple uses, and straw is also a roughage. It is characterized by high crude fiber content and lignin and hemicellulose form a firm binding layer, which tightly surrounds cellulose and hinders the contact of enzymes and other substances with cellulose. Lignocellulose can be used by ruminant cattle, sheep and other livestock It can be absorbed and utilized, bu...
