Cold-resistant feeding technology of live pigs

The cold-resistant feeding technology of live pigs is mainly used to reduce the adverse effects of rainy, freezing and other disastrous weather and disaster recovery. The main technical contents are as follows: 1. Strengthen protection against cold and warmth. The sow delivery room and piglet nursery are the key points of cold prevention and warmth. The closed pig house should use plastic film, foam board, old packaging bags and other materials to close the north window to prevent cold wind from entering the pig house; the south window should also be closed, but leave some vents; the open pig house can be closed with plastic film, especially the north side of the pig house must be closed. Open the south window properly when it is sunny during the day. 2. Provide additional heat source for piglets. Through coal stove heating (but with chimneys), hanging infrared lights and other ways to provide additional heat for newborn piglets and newly weaned piglets. 3. Increase the feed energy appropriately. Under the conditions of heavy snow and severe cold, the amount of energy and feed needed by pigs increased greatly. Cold weather pregnant sows each day to increase 1 kg of feed, other live pigs (piglets, fat pigs, lactating sows) do not limit feed intake, should be open feeding. You can also increase energy feeds such as corn, wheat and brown rice by 10-15% on the original basis. 4. Strengthen the feeding and management. In particular, it is necessary to strengthen the management of suckling piglets, focusing on preventing frozen piglets and freezing to death, making suckling pigs eat good colostrum, strengthening the replenishment of suckling pigs, strengthening the removal of manure and urine in pig houses, not allowing pig manure and urine to remain in pig houses, and controlling the concentration of harmful gases. Do not exceed the standard. 5. Do a good job in epidemic prevention. In the cold season, the possibility of outbreaks of some viral diseases increases. Pig farms should strengthen the work of immunization. It is necessary to strengthen the prevention and control of infectious gastroenteritis, epidemic diarrhea, foot-and-mouth disease and other epidemic diseases. At the same time, strengthen disinfection and isolation work, strictly prevent infectious diseases from entering pig farms.
