What are the design methods for pig houses that do not require manure cleaning?

AbstractThe upper floor can be designed as a pig-raising workshop, and the lower floor as an organic fertilizer processing workshop. That is, raise the height of the first floor where pig manure is stored, seal both floors completely, then install automatic exhaust fans, turn the original concrete slabs into slatted floors, and use steel bars to make a mesh bed, and design the pig drinking trough inside the wall.

1. Design of a pig house that does not require manure cleaning

1. You can raise the height of the first floor where pig manure is stored, changing the first floor from its original height of 1m to 2.5m. In this way, from the time the pigs enter the pen to the time they leave the pen, all the manure from 4 months can be piled up and fermented here, and the space for storing manure is sufficient. In order not to let the manure flow outside and pollute the environment, the whole building can also be sealed. Since the space is sealed, the foul air will have a relatively large impact on the pigs, so automatic exhaust fans need to be installed in the pig house.

2. Generally, if the gaps in a concrete floor are large, manure will easily leak through, and pigs may get their feet caught. If the gaps are small, the pigs will not get their feet caught, but the manure leakage effect is not very good. If you want the gap size to be suitable, you have to use steel bars as the material. In the pig house, the drinking trough needs to be designed inside the wall. Every time the pigs drink water, they can only stretch their heads into the hole in the wall. The water that flows out when they play will be collected through pipes and continue to be recycled, and it will not affect the fermentation of the manure on the first floor.

3. Research has found that a strain of bacteria with strong performance and relatively stable passage was discovered from the large intestine of pigs. After the developed native bacteria strain is expanded and propagated, a feed processing plant is commissioned to add it to the feed, and then it is processed into fermented feed. After the pigs eat it, this bacterial community has a relatively high survival rate in gastric juice.

4. Generally, every 3-5 days, you can spray the entire pig house and manure pile with probiotics cultivated by yourself. Before the manure is decomposed, a small amount of fly maggots will grow. At this time, chickens can be sent out. The number of chickens does not need to be too many; just put a little over ten chickens into 1 pig house. As the pig manure continues to ferment and mature, the chickens will also slowly grow up. In this way, it can not only effectively ensure the healthy growth and development of the pigs, but also help farmers obtain more economic benefits.

2. Precautions for disinfection of pig houses

1. Generally, the pig house needs to be inspected to determine which parts need focused disinfection, and pig manure and food residue, etc. need to be cleaned up in time. In addition, the dust accumulated on the doors and windows of the pig house also needs to be swept clean. This can effectively avoid the phenomenon of dust flying when spraying disinfectant and when cleaning, so as to prevent pollution of the air.

2. After initially cleaning the pig house, further water washing can be carried out, because some pig houses have been used for a relatively long time. Especially in summer, due to the relatively high temperature, many kinds of garbage that are difficult to clean may give off various odors and easily breed bacteria,  and some pathogenic bacteria with strong vitality are relatively difficult to truly eliminate.

3. Therefore, when cleaning the pig house, after simple disinfection, further water washing and disinfection are also needed, which is helpful for killing bacteria. Generally, a high-pressure water gun can be used for washing, which can clean the difficult-to-clean corners of the pig house and help improve the quality and efficiency of cleaning.

4. When farmers disinfect the pig feeding troughs and drinking utensils, it is recommended to handle them separately, because the disinfectant contains a certain degree of toxicity, and these utensils will directly contact the pigs' mouths. If details are not paid attention to, it will affect the health of the pigs.
