How to keep a pig farm warm? Here are several methods for reference

Winter temperatures drop noticeably, and under the influence of cold stimulation, pigs are highly prone to illness, which affects normal growth. If correct and feasible methods can be adopted to scientifically prevent cold and increase warmth, it will not only promote healthy fattening of pigs but also reduce the occurrence of various respiratory and intestinal diseases, increasing the income of pig farmers. The author now introduces the following common insulation methods:

Repair the pig house. The pig house should be located in a high, dry, sunny place, with the window openings on the north, west, and east sides sealed, and the roof and cracks in the four walls repaired in time. The windows and ventilation holes of the pig house should be 1-1.5 m from the ground, and the size of the holes should be adjustable to keep the house temperature relatively stable. Hang wind-blocking curtains. All doors and windows of the pig house should be covered with plastic sheeting to keep warm and resist the cold. On the windward side, use straw or corn stalks to build a windbreak wall or pile haystacks to block the wind and prevent it from invading the pig house. Build a house within a house. A house within a house can be built inside the pen using plastic film and felt. Plastic film can transmit light and retain heat, while felt can breathe and gather warmth, raising the house temperature by 5°C-7°C. Building a house within a house has the characteristics of low investment, simple construction, and quick results, but it should be adapted to local conditions and kept simple. It can be built as a suspended ceiling form about 1.8 m high, while leaving a ventilation window above for timely ventilation and air exchange. Increase bedding. Spread 15-20 cm thick sawdust, rice husks, or dry grass on the pig bed; besides keeping warm, it can also absorb moisture and remove dampness. Pay attention to frequently checking and replacing urine-soaked dry grass. When pig urine is found, promptly remove the wet grass and replace it with dry grass to keep the pig house dry and comfortable. At noon when the weather is good, spray peracetic acid, or add quicklime under the bedding to remove ammonia and moisture, and appropriately open the joints of the house within a house to expel ammonia and dampness from the house. Increase stocking density. Raise scattered pigs together in groups. The number of pigs in the house can be increased by 30%-50% compared with summer. Using the body heat among pigs to keep warm can raise the house temperature. Note that when new pigs enter the pig house, this should be done after dark, and after spraying the pigs' bodies with liquor or low-concentration Lysol water, they can then be grouped together. At the same time, the keeper needs to observe for a few hours to prevent the pigs from fighting. You can also choose clear, warm days to drive the pigs outside to bask in the sun, strengthen exercise, and improve the pigs' resistance to cold weather.
