Several methods of heat preservation in pig farm

The temperature drops obviously in winter. Under the influence of cold stimulation, pigs are easy to get sick and affect the normal growth. If we can adopt correct and feasible methods to prevent cold and increase temperature scientifically, it can not only promote the healthy fattening of pigs, but also reduce the occurrence of various respiratory and intestinal diseases and increase the income of pig farmers. The author now introduces the following common heat preservation methods:

Repair piggery site should be high, dry, sunny place, fortress north, west, east three sides of the window hole, timely repair the roof and the cracks in the four walls. The windows and vents of the pigsty should be 1-1.5 meters from the ground, and the size of the hole can be adjusted to keep the temperature relatively stable. The whole doors and windows of the hanging windscreen pig house should be covered with plastic sheeting to keep warm and keep out the cold. In the windward direction, straw or corn stalks are used to build a wind barrier or stack to block the wind to prevent the wind from invading the pig house. To build a house in an enclosure, plastic film and blankets can be used. The plastic film can transmit light and heat preservation, the felt can permeate and gather the temperature, and the temperature can be increased by 5 ℃-7 ℃. The building of the house has the characteristics of low investment, simple manufacture and quick effect, but it should be adapted to local conditions and be simplified to build a ceiling form about 1.8 meters high. At the same time, a ventilation window is left above for timely ventilation. Add cushion to spread sawdust, rice husk and hay 15-20 cm thick on the pig bed, which can not only keep warm, but also absorb moisture and remove moisture. Pay attention to check and update the wet hay frequently, and find that pig urine should be replaced with hay in time to keep the pigsty dry and comfortable. Spray peracetic acid at noon when the weather is fine, or add quicklime under the cushion to remove ammonia and moisture, and properly separate the junction of the house to remove ammonia and moisture. By increasing the feeding density, the scattered pigs will be raised in groups, and the number of pigs raised in the house can be increased by 30% 50% compared with that in summer, and the house temperature can be increased by using the body temperature between pigs to keep warm. Note that the piggery should be carried out when it is dark, spray the pig behind with wine or low concentration of Lysol water and then join the group, and the breeder needs to observe for several hours to prevent the pig from fighting. You can also choose to drive the pig out to bask in the sun on a sunny day to strengthen exercise and improve the pig's resistance to cold weather.
