What if the temperature is high in summer?
1. Temperature control of piggery:
In order to ensure the normal production of pig farms in summer, effective temperature regulation measures must be taken according to the temperature requirements of various pigs, and the pigsty should be well ventilated to discharge the heat in the pigsty and reduce the temperature of the pigsty. Suitable air inlet and air outlet can be set in the pigsty. If the pigsty area is large, it is best to install negative pressure fan and cooling water curtain for ventilation and cooling. In recent years, a variety of cooling facilities suitable for different pig herds have been developed at home and abroad, which have been widely used in large-scale pig production. In addition to the fan, there are nozzles and environmentally friendly air conditioners. For rural farms with no conditions, it is suggested to build a shallow pool in the pigsty, or directly pour some water on the ground to let the pigs lie in the water to cool down, or spray fog on the pigs with a sprayer to absorb the heat from the pigs through steam evaporation to achieve the purpose of cooling down. The pigsty temperature is generally controlled at around 25℃, and it is best not to exceed 30℃. Most of the rural areas are open pig houses. Before the arrival of high temperature, it is necessary to set up a shed to shade the sun to avoid heatstroke caused by direct exposure of pigs in the sun. A certain number of trees can also be planted around the pigsty, which can not only purify the air, but also play the role of shading.

Second, the sanitary environment management of pig farms:
Summer is the season when germs are very active, and the high temperature and high humidity environment can easily cause many diseases of pigs. In order to prevent the occurrence of pig infectious diseases, pig farms must pay attention to the cleaning and disinfection of pig houses. It is necessary to clean pools and sinks regularly, remove feces in time, and disinfect pigsty and its surroundings irregularly. There are also many mosquitoes in summer. If pigs are bitten by mosquitoes for a long time, it will not only affect production, but also easily lead to diseases, so it is necessary to kill insects in time. Trichlorfon can be sprayed with appropriate amount of water, but the concentration should not be too high, otherwise it will affect pigs. In addition, pigs must be vaccinated regularly to prevent diseases.

Third, the selection of nutritional conditions for pig feed:
Some farmers are greedy for cheap and buy some inferior feed, which is very undesirable. It is easy to make pigs malnourished, leading to poor growth and decreased resistance, and many people suffer losses every year. Under high temperature, the appetite and feed intake of pigs will decrease, and the growth of pigs will be seriously affected. Therefore, at high temperature, it is necessary to properly improve the nutritional level of feed, and at the same time adjust the feeding methods, preferably in the morning and evening when the weather is cool, to ensure that pigs are full and eat well. Adding a small amount of baking soda to the diet of fattening pigs can effectively promote appetite, prevent poisoning, and add appropriate amount of edible oil to pig feed to increase energy. In hot environment, pigs need some vitamins to resist heat stress, especially vitamin C. It can not only increase the resistance of pigs to infectious diseases and poisoning diseases, but also promote wound healing and intestinal absorption of iron.
