Every pig farmer in winter and spring will face the problem of increased mortality from pigs, and most people are habitually blamed for contagious epidemics. Of course, pathogens such as winter and spring number 5 and epidemic diarrhea survive longer in low-temperature environments and have seasonal epidemics. However, the incidence of most pig farms is not necessarily related to the above, and it is also related to low temperatures. Therefore, it is important to manage the low temperature and control the pig house environment (conservation and piglets). Here, the author will talk about some management details that are overlooked by pig farmers in pig farm inspections in recent years for reference. Ground of the pig house First of all, pay attention to some details in the design of the pig house, focusing on the nursing home delivery room. In order to facilitate sanitary cleaning, the nursery houses are usually made of slatted ground, but there are leaks and ventilation, so some pig farms will use infrared lamps plus floor or incubators, and also have installed electric heating plates or plumbing pipes, so that the beds can be used. The surface temperature is improved. Some farms also installed hot air heaters, but they did not completely solve the problem. Some of them even died. This was in addition to the fact that the insulation board might not be repaired in time or the infrared lamp and the floor insulation were not good, but also the child care unit. The wall is related to the design of windows and doors. Conservation Design of Small Cell Walls Most of the nursery units generally use a small rebar welded grid, which is the same wall. Large-scale pig farms have larger nursery units made up of small units, which makes it difficult to integrate them if they are not properly installed with doors and windows. The main reason is that the cold wind blown by the door and window blows directly to the pig body. This will cause the pig to wear no clothes and no place to shelter from the wind. It is often blown and it is easy to get sick. The wall between the delivery room and the nursery in the Spanish farm is made of detachable, weatherproof steel panels. However, it is a good choice for the grid partition walls to cool down in hot weather. Door and window design and installation Most of the pig farm doors and windows are open to the bed of the pig house. Some of the windows are even lower than the beds. This is good for cooling on a hot day. The problem is that in winter and spring, the cold wind blows directly to the pig body and the bed. At this time, the nursery pigs that are near the air intake of the doors and windows and are blown by cold air will have thick hair, poor body, and much cough. Even more disease. Therefore, it is necessary to add a screen in front of or in front of the door to block the wind from blowing in. In Spain, there are generally 1.6 to 2 meters of sealed aisle outside the pig house. Doors and windows and curtains are installed outside the aisle, which is conducive to air preheating and pre-cooling. The piggery is under negative pressure ventilation, so that there is no cold wind blowing directly on the bed of the pig house and the piggery; the fattening houses are also like this, the discs of the discs are installed under the roof vents, and the curtains and window doors Open up and down. It is common for domestic pig farms to use sliding doors or pull-up curtains. This difference is reflected in the cold wind will not be directly blown to the bed and pig body. This is the difference between the design concept and details, resulting in differences in the management of the pig house temperature, which in turn causes the pigs in the winter and spring farms to be poorly maintained.
