What are the hazards of wet pighouses?

As the saying goes: "Pigs must be kept well, and the bar is full and full." This sentence means to keep the pigs well, as long as the pens are dried and fed. However, in the winter, many pig farms that use traditional sheds have tighter shelters for pigs in order to keep better insulation. Fan ventilation is too small, herd density is too high, and swine urine is large for individual pigs. The amount of evaporated water and the amount of exhaled water vapor are large and cannot be discharged in a timely manner. The humidity in the pig house is too high. In some piggery houses, due to poor roof warming measures, water vapor condenses into water droplets on the roof and drops to the floor of the pig house. Pig house damp. Compared with traditional pig houses, the pigs that use the technology of dry fermentation of fertilized bed to raise pigs are required to maintain a temperature of 35 to 50°C in the central fermentation layer of the fermentation bed, so that the fermentation bed can basically form a constant-temperature bed, effectively avoiding the wetness of the pigsty. Causes a series of swine diseases.

What diseases can be caused by wet pighouses? The first is diarrheal disease. The causes of infectious and non-infectious diarrhea are basically caused by low temperature and high humidity. The cold and wet environment can easily cause various intestinal diseases. The second is wet toxicity. The pigs live in moist environment. Over time, wind evils, wet poisons invade the body stagnate, easy to induce wet toxicity; In addition, cold and wet floors often lead to swollen stomach after the pigs get cold, resulting in indigestion, resulting in slow food, eating diarrhea Such as; the last humid air, ammonia, hydrogen sulfide and other toxic and harmful gases content increased significantly, the pig's respiratory system, eye conjunctiva stimulated by these gases, then inflammation, and then induce respiratory disease in pigs.

The dampness of the pig house will bring so many pig diseases and cause such a large economic loss. How to solve the problem of wet pig house?

First, create a dry environment. The pig house should be built on top of a high dry land, facing north and facing south, the ground should be higher than the surface. The use of groin dry fermentation bed breeding technology to build a fermentation bed on the ground, the ground moisture-proof at the same time do not have to clean up the pig manure urine, pigpen padding late can also be used as fertilizer applied to farmland.

Second, strengthen insulation management. The low temperature in the pig house is an accompaniment to wet damage and is not conducive to the normal growth of pigs. In comparison with traditional sheds, Jinbao’s dry-slumping bed is compared with the traditional shed. The surface of the broth is due to the physical and chemical effects of fermentation bed urine fermentation. It will provide a constant supply of heat for the shed, and the “heat source” in the center layer of the fermentation bed will make the pig She is insulated from "low-temperature wetness."

Third, do a good job of ventilation. The effective method for dehumidification and moisture protection of piggery is ventilation. On the one hand, it takes away the damp gas inside the housing and blows dry the ground; on the other hand, it removes the dirty air and exchanges fresh air. However, attention should be paid to solving the contradiction between ventilation and heat preservation, and controlling the ventilation volume. The wind speed in the house should not exceed 0.1 to 0.2 meters per second, and the temperature increase work should be done in time before and after ventilation to make the temperature change during ventilation less than 5°C. , and return to normal in the short term.

Fourth, timely removal of excrement. Traditional pig pens excretion pig manure is an important cause of poor air and humidity, it should be cleaned swine waste water; relatively conventional pens, the dry shake Gymboree fermentation bed is pens "species Cleansing of urine, artificially stalked, "Do not worry about the accumulation of feces and urine caused by a large number of wet problems.

Fifth, reduce the stocking density. Pigs are intensively reared, which is conducive to insulation in the house. In turn, the density is too large and the humidity in the house will increase. Therefore, in order to maintain a reasonable breeding density, each finishing pig generally occupies 0.8 square meters in the winter. Similarly, the use of groin fermentation bed housing also needs to maintain a breeding density of 0.8 to 1 square meter per pig.

Sixth, early prevention of gastrointestinal diseases. Bacterial, virus-induced piglets, gastroenteritis, etc. will also increase the surface humidity and air pollution. Should seize the pig gastrointestinal susceptibility stage, do a good job of early drug prevention, so that it is less or no incidence, in order to control the ground moisture and air pollution caused by this, optimize the small environment. Similarly, the relative incidence of this disease is relatively low for a group of pigs farmed on a fermentation bed using a golden tycoon as opposed to a traditional shed.
