he right temperature is very important when raising pigs: in a cool pigsty, a part of the energy from the fodder is used not to grow but to sustain the body's temperature. But in too warm an environment, the pigs lose their appetite and their gain decreases again. The highest temperature of about 35 °C is needed by the suckling pigs when they are born, weaners need 19–25 °C and pigs only 18 °C.
Whether the temperature is suitable for the pigs can also be determined by simply observing the pigs. When the pigs are lying next to each other, then the temperature is just right for them. In a cold pigsty, pigs climb on top of each other in order to keep warm. In too hot a pigsty, the pigs keep away from each other when lying or are even in the dung in order to get rid of the excess heat.
