A microbial fermentation bed large bar ecological pig house for pig breeding

Abstract

The invention provides an ecological live pig raising house with a microbial fermentation bed and a large pen. The ecological live pig raising house is characterized in that the area of a pig house ranges from 1000 square meters to 2000 square meters, a wall is arranged on the periphery of the pig house in a surrounding manner, and the height of the wall ranges from 0.8m to 1.2m; a steel framed green house of the pig house is erected above the ground surrounded by the wall, shutter fabrics are respectively arranged on two sides of the long edges of the steel framed greenhouse, a wet curtain and a negative-pressure fan are respectively arranged on two sides of the short edges of the steel framed greenhouse, and spraying cooling devices are mounted on the outside of a roof; a sidewalk is arranged in the pig house along the wall on the periphery of the pig house, and the pen is arranged on the inner side of the sidewalk in a surrounded manner; fermentation bed packing, feeding troughs and a water trough are arranged in the pen, axial-flow fans and miniature spraying cooling systems are arranged at certain positions below the roof, and the distances from the certain positions to the roof range from 1.2m to 1.5m; the temperature and the humidity of the inside of the pig house can be automatically regulated according to data information of the brightness, the temperature, the moisture, the humidity, the air quantity and the amount of rainfall of an environment outside the pig house. The ecological live pig raising house has the advantages that the ecological live pig raising house is low in construction cost and suitable for ventilation cooling in summer, has a large raising space and an activity range and can be conveniently mechanically operated, and heat stress of pigs and fighting of individual pigs can be reduced.

Description

【Technical field】 [0001] The invention relates to a microbial fermentation bed large bar ecological pig house for raising pigs. 【Background technique】 [0002] Pig raising in microbial fermentation bed is a pig raising technology that has emerged in recent years. It is based on microecological theory and uses microbial fermentation control technology to mix microorganisms with sawdust, chaff or straw in a certain proportion, and use them as organic bedding after high-temperature fermentation. , to make a fermentation bed. The pigs are raised on the fermentation bed, and the feces and urine excreted by them are decomposed and absorbed by microorganisms in the bedding in a timely manner. There is no need to wash the pig house, and no feces, urine and sewage are discharged outside, forming a zero discharge of no pollution, no emission, and no odor. Clean production controls the environmental pollution caused by raising pigs from the source, and achieves the purpose of raising ...

AI Technical Summary

Problems solved by technology

However, the fermentation bed pig house occupies a large area, with an average of 1.2-1.5 square meters per pig (1-1.2 square meters per pig in conventional breeding methods); during the breeding process, the litter needs to be turned irregularly, which consumes a lot of money. Manual, and the small pen area of ​​conventional pig houses is not suitable for large-scale mechanized operations; in addition, the high temperature time in southern China is longer in summer, and heatstroke prevention and cooling to reduce heat stress are the key problems to be solved in the fermentation bed
