Pig fermenting bed

Abstract

The invention discloses a pig fermenting bed. The pig fermenting bed comprises an upper layer, a middle layer and a lower layer, wherein the upper layer is 20-30cm in thickness and is prepared by mixing and fermenting the following raw materials in parts by weight: 40-50 parts of rice hull powders, 30-40 parts of saw powders, 10-20 parts of silkworm excrements, 10-20 parts of bran and 0.2-0.3 part of enzymes, and the water content of the upper layer is controlled to be 40-45%; the middle layer is 10-20cm in thickness and is prepared by mixing and fermenting the following raw materials in parts by weight: 30-40 parts of waste materials discharged by the fermenting bed, 20-30 parts of coconut shell powders, 10-15 parts of modified palygorskite powders, 10-20 parts of plant straw powders, 10-20 parts of cottonseed meals and enzymes, and the water content of the middle layer is controlled to be 20-30%; and the lower layer is 20-30cm in thickness and is prepared by mixing and fermenting the following raw materials in parts by weight: 30-40 parts of pot-ales, 40-50 parts of loess, 20-30 parts of bagasse and 10-20 parts of corncobs, and the water content of the lower layer is controlled to be 30-40%. The fermenting bed disclosed by the invention plays good roles of helping the pig to digest, and increasing the utilization ratio of feeds, the daily gain of the pig and the economical benefits and the like.

Description

technical field [0001] The invention relates to a fermentation bed, in particular to a pig fermentation bed. Background technique [0002] At present, the annual production of livestock and poultry manure in China has reached 1.9 billion tons, more than twice the amount of industrial solid waste discharge. Pollutants in intensive and large-scale livestock and poultry farms and breeding areas are on the agenda. The traditional pig raising technology in my country is that pigs are raised in the pig house, and the manure is piled up outside the pig house. The main defect of this technology is the foul smell in the pig house, which requires a lot of water to flush the pen, and the manure accumulated outside the pig house pollutes the soil and groundwater. . The zero-emission fermentation bed pig raising technology that is currently being promoted allows pigs to grow on fermented bedding materials made of sawdust and rice husks, excrement and urine need not be cleaned, pig house...
