1. Improve the environment. Reducing the proportion of cement land in the pig farm can reduce the ground temperature. Increasing the green area can reduce 3 ℃ ~ 4 ℃ and reduce the heat radiation by 80%. But it is not suitable for a variety of tall trees that affect ventilation and attract wild birds that are not conducive to epidemic prevention.

2. Scientific feeding. In summer, pigs are fed with green feed rich in vitamins and minerals and cool feed with peels such as watermelon peel, and seasonings such as salty, fresh or fragrant flavors are properly added to the mixture to improve feed palatability and feed intake of pigs. do not feed moldy feed. In summer, pigs can be fed 4 times a day to reduce the activity of pigs in the hottest period. They can be fed at 4 am, 10:00, 4 pm and 9 pm respectively. Keep plenty of cool drinking water in the pig trough. Pigs are also given 0.5% brine once a day to regulate their body temperature.

3. Safe against heat. When the pigs were above 35 ℃ or minus 5 ℃ ~ 10 ℃, the feed intake was less and the weight gain was slow. The hot season. The corresponding feeding and management should be given according to the category and physiological stage of pigs. The boar is fed twice a day, plus green fodder or dilute feed at noon, and breeding and exercise are carried out in the morning and evening. Spray water on the pig body and ground at 1-3 pm every day, and the light is reduced to 8-10 hours. if the number of mating is less, the amount of concentrate feeding should be reduced to prevent overweight and poor libido.

4. Safety and epidemic prevention. In addition to doing a good job of immunizing pigs according to the immune procedure, we should also do a good job in prevention and treatment of diseases in high-temperature pigs, such as sow uterine inflammation-mastitis-no milk syndrome, piglet yellow and white dysentery, coccidiosis, toxoplasmosis, eperythrozoonosis, chlamydia and so on.
