Novel environment-friendly farrowing sow house and sow breeding method

Abstract

The invention discloses a novel environment-friendly farrowing sow house and a sow breeding method. The novel environment-friendly farrowing sow house comprises at least one circular farrowing sow house, and a first passage and a second passage are in nested arrangement and reserved in the middle of each farrowing sow house along a symmetry axis direction of the sow house, wherein the top end of the inside first passage is sealed while the bottom end is communicated with an air outlet of an air inlet device, and the bottom end of the outside second passage is sealed while the top end is communicated with external air. Each storey of the farrowing sow house mainly comprises an inner circular sow house, an outer circular sow house and a passage (230) between the inner circular sow house and the outer circular sow house, wherein the inner circular sow house and the outer circular sow house are partitioned into a plurality of compartments by barriers. Each compartment is provided with a sow positioning unit, each sow positioning unit comprises a rectangular sow positioning space formed by small fences and a feed trough at one end of the sow positioning space, and each feed trough is positioned at one end away from the corresponding passage.

Description

technical field [0001] The invention relates to the field of pig breeding, in particular to a novel environment-friendly farrowing sow house and a feeding method. Background technique [0002] Most of the pig houses in our country are single-layer with large spacing and occupy a lot of land. The structure of the pig house is not good, and the functions of wind resistance and snow resistance are poor. It cannot be airtightly sterilized by gas, and the disinfection is not complete. Only equipped with water curtain cooling facilities, unable to maintain constant temperature and humidity in all seasons, automatic ventilation, and high concentration of harmful gases in pig houses in winter. Pig manure cannot be harmlessly fermented into organic fertilizer on the spot after it is dried, and it is not easy to meet the discharge standard after pig urine flushing water is biogas fermented. The environmental protection investment is large and the operating cost is high. There is no...

AI Technical Summary

Problems solved by technology

The structure of the pig house is not good, and the functions of wind resistance and snow resistance are poor

Unable to airtightly sterilize with gas, incomplete disinfection

Only equipped with water curtain cooling facilities, unable to maintain constant temperature and humidity in all seasons, automatic ventilation, and high concentration of harmful gases in pig houses in winter

Pig manure cannot be harmlessly fermented into organic fertilizer on the spot after it is dried, and it is not easy to discharge pig urine flushing water to reach the standard after biogas fermentation. The environmental protection investment is large and the operating cost is high.

There is no purification treatment for the breeding waste gas, the pig house and its surroundings have a strong odor, there are many mosquitoes and flies, and the environment is not good

Feeding with dry feed, although drinking fountains are installed, the amount of drinking water for pigs is insufficient, which affects health

Due to the poor environment and improper feeding methods, the pigs are in a semi-stressed state and are prone to disease. Therefore, the farmers add a large amount of antibiotics to the feed and drinking water. The drug residues in pork cannot meet the standards, and food safety has a long way to go.

Although there are a variety of new pig houses and various new feeding modes, it is still impossible to solve the above problems systematically
