Biogas residue biological-fermentation and feed preparation technology

Abstract

The invention discloses a biogas residue biological-fermentation and feed preparation technology. According to the biogas residue biological-fermentation and feed preparation technology, biogas residues can be turned into wealth, use of hormones and antibiotics for animal feeds can be reduced, growth and development of animals can be promoted, diseases of the animals can be reduced, the price of the feeds can be increased, nutrition and mouth-feel of meat can be improved, and economical benefits of animal breeding can be improved; in addition, the feeds are endowed with special flavor after being fermented, so that the palatability of the feeds is improved, the appetite and the food intake of the animals are improved, and a growth and development process of the animals is accelerated.

Description

technical field [0001] The invention relates to the field of animal feed preparation, in particular to biogas residue biofermentation and feed preparation technology. Background technique [0002] With the continuous development of ecological agriculture, people's enthusiasm for developing biogas ecological agriculture is getting higher and higher, and the use of biogas residues is gradually being developed and utilized. Biogas residue is rich in organic matter, humus, micronutrients, various amino acids, enzymes and beneficial microorganisms, among which humic acid accounts for 10-20%, organic matter accounts for 30-50%, total nitrogen accounts for 1.0-2.0%, and total phosphorus accounts for 0.4-0.6%, total potassium 0.6-1.2%, it is not only a high-quality agricultural fertilizer, but also a valuable breeding feed. Biogas residues are rich in resources and low in price. However, the effective utilization of biogas residues is rare at present, and the application in aquacul...

AI Technical Summary

Problems solved by technology

Biogas residues are rich in resources and low in price. However, the effective utilization of biogas residues is rare at present, and the application in aquaculture feed is even rarer.

[0003] At present, a large number of feeds containing various drugs such as hormones and antibiotic additives are emerging. Hormone, antibiotic additives and various drugs are often used in excess of the standard in production. These substances remain in animals and seriously affect human health.
