Pig farmers, take note: never spray cold water on pigs in the height of summer

In the height of summer, when temperatures are high, pigs often pant heavily from the heat. Some farmers, worried that the pigs will get sick from the heat, spray cold water on them, hoping to cool them down and make them feel more comfortable, not realizing that this does more harm than good.

Pigs pant from the heat because they do not sweat effectively, so the heat in their bodies cannot be released for the time being. If cold water is sprayed on the pigs at this point, the strong cold stimulus makes the sweat pores all over their bodies contract sharply, the release of body heat is blocked, and their body temperature instead rises abruptly. In mild cases this causes high fever and lung inflammation; in severe cases it leads to death. Therefore, in the height of summer, never use the method of spraying cold water on pigs to cool them down.

If the weather is hot and the pigs really do need to be cooled down and relieved of the heat, you can drive them to a well-ventilated, shady place, then splash some cold water on the ground (preferably clean concrete ground) and let the pigs lie down quietly there to rest. You can also dig a pit inside the pigpen and fill it with enough cool well water for the pigs to "wallow in the mud."
