In this case the pen mates were fighting with this pig and it collapsed due to fatigue. Fatigued pigs display signs of acute stress (open-mouth breathing, skin discoloration, and/ or muscle tremors), are in a metabolic state of acidosis, and may have elevated body temperatures. However, controlled research has demonstrated that the vast majority of fatigued pigs can recover metabolically if the stressors are removed, and pigs are allowed to rest for two to three hours.
