The temperature directly affects the growth of pigs. How should the pigs be kept warm before the cold weather arrives?
(1) The protection of your pig house in the winter when a thieves wind invades the pig house and attacks the pig's body will cause pig colds and pneumonia and other diseases. Therefore, a thorough inspection of the pig house should be conducted, and the bad, dangerous and leaking pig house should be repaired in time and plugged. Wind tunnels, mud cracks, to prevent intrusion of thieves; hanging curtains at the door to enhance the warm effect.
(2) Padding bed In winter, 15 cm thick corn leaves or other hay should be placed on the pig bed, which can absorb moisture, remove moisture, absorb harmful gases, and increase pig bed temperature.
(3) The use of heating equipment such as heat lamps, steam insulation, boiler heating and insulation, and conditional air conditioners.
(4) Carefully feed sorghum and corn and other energy feeds should be properly added when formulating pig diets. The supply of feed should be adequate, around zero every night, plus one night diet to enhance the ability to resist cold and disease and promote rapid growth. The winter feed formula should increase the energy feed by 10%-30% while keeping the protein level unabated. Maize, rice and other high energy-containing raw materials can be used, and animal and vegetable fats and oils can be added when necessary. Experiments have confirmed that adding 2%-3% of animal and vegetable fats and oils in the diet can increase pig weight gain by 12%-15%, and save 8%-10% of feed per kilogram of weight gain.
(5) Increase the stocking density In the winter, the number of pigs in the house can be increased by 1/3 to 1/2, so that the pigs can warm up to each other's body temperature. In addition, the pigs can dissipate more heat and can increase the temperature. Pigs entering new pigs should be carried out on dark days. They should be sprayed with the wine or a low concentration of odor and then sprayed on the pigs. The keeper must observe for several hours to prevent the pigs from fighting.
(6) The higher the humidity in the piggery is, the more cold the pig feels and the pig's dermatosis, respiratory diseases, infectious diseases and parasitic diseases can be easily caused. In order to prevent moisture and leakage, it is necessary to diligently change the hay and loose soil, let the pigs defecate urine, keep the pigs lying in a clean and dry place, provide pigs with a comfortable living environment, and promote winter fattening pigs. The growth and development of health.
In fact, there is a simple, convenient and cost-effective way to get your pigs to sleep on a fermentation bed, to use a fermentation bed, and to use a fermentation auxiliaries to make a standard sty pig bed. 50 cm sawdust is required. Practice has proved that the surface is not fermented, the fermentation layer is generally less than 10 cm above the surface, and Jinbao fermentation aids are added. After a few days, sawdust will begin to ferment. The surface temperature will be around 20 degrees, not too high. This high temperature is enough to maintain the requirements of indoor pigs, so it is natural heating equipment.
