Round building hog house with three stages of steps and hog breeding method

Abstract

The invention provides a round building hog house with three stages of steps. The round building hog house comprises at least one cylindrical hog house building; a channel is reserved in the middle of each hog house building in the symmetry axis direction of the hog house building; a waste gas collecting and treating device communicated with a top end outlet of the corresponding channel is arranged at the top of each hog house building, and a hog manure and urine collecting device communicated with a bottom end outlet of the corresponding channel is arranged at the bottom of each building. Floor planes in each hog house building are divided into a plurality of symmetric hog lots through lattices in the radial direction; a floor of each hog lot is provided with three stages of sequentially descending steps close to the inner side of the corresponding channel from the lateral outer side away from the corresponding channel; the outermost steps serve as hog sleeping areas; the middle steps serve as hog feeding areas; the innermost steps serve as hog excretion areas; floors of the steps are inclined from the outer side to the inner side from high to low. The innermost steps are communicated with the channels, so that excrement in the excretion areas falls into the hog manure and urine collecting device through the channels.

Description

technical field [0001] The invention relates to the field of pig breeding, in particular to an environment-friendly pig house. 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 purification treatment for the bree...

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 pig houses and various new feeding modes, it is still impossible to solve the above problems systematically
