Like people, the average body temperature of Dutch pigs is higher than that of people. The average person's temperature is within 36 degrees or 37 degrees, while the temperature of Dutch pigs is 37 to 38 degrees. As long as there is a cold shelter around the pigsty, the lowest environmental temperature that pigs can bear is 0 to 2 degrees. It's only 5 degrees here, and it's even lower at night, so I surround the nest with a hard straight board and put a pile in the pigsty.
