With the onset of winter, the weather gradually becomes colder, in order to ensure the health and performance of the sows, winter sow breeding needs to pay attention to the following:
1. Protect against cold and keep warm
In winter, the weather is cold, and sows are prone to freezing, so they need to do a good job of keeping warm from the cold. The outside of the pig house can be covered with plastic film, straw mats and other insulation materials, and at the same time, heating equipment can be installed inside the pig house, such as electric heating plates, infrared lamps, etc., to keep the temperature of the pig house appropriate.
2. Increase feed nutrition
Winter temperatures are low, sows need more energy to maintain body temperature, and feed nutrient intake needs to be increased. Vitamins, minerals and other nutrients can be added to the feed to improve the resistance of the sow. It is recommended to add to the feedHealthy blood, replenish blood nutrition for sows, and prevent the occurrence of hypothermia in sows.
3. Keep the pig house dry
In winter, the humidity in the pig house is easy to increase, which can easily cause sows to get sick. It is necessary to keep the pig house dry, clean up the manure and sewage in the pig house in time, and prevent the wet road surface from being slippery due to moisture, resulting in sow falls and miscarriages.
Fourth, increase the light
The light hours in winter are short, and sows are prone to lack of light, which affects reproductive performance. Lighting equipment such as fluorescent lamps or infrared lamps can be installed in the pig house to increase the light time of the sow.
5. Disease prevention
Winter is an important period for sow reproduction and growth, and it is also a period of high incidence of diseases. It is necessary to strengthen feeding management, regularly disinfect the pig house, and pay attention to the sow's appetite, body temperature, excretion, etc., and timely detect and improve the disease.
In short, winter sow breeding needs to do a good job of cold and warmth, increase feed nutrition, keep the pig house dry, increase light and prevent diseases and other aspects to ensure the healthy reproduction and growth of sows.
