Which of the following is a symptom of porcine stress syndrome?

The rapid rise in temperature is indeed a symptom of porcine stress syndrome (PSS), which is a genetic condition that affects pigs, leading to a hypermetabolic state. PSS is often triggered by stressors such as handling, transportation, or high environmental temperatures. When these stressors apply, the affected pigs experience a sudden increase in muscle metabolism, which generates excessive heat, resulting in a rapid rise in body temperature.

This symptom is critical to recognize as it can lead to severe consequences, including death if not managed properly, making it essential for those working with pigs to be aware of the signs of PSS. Understanding this condition allows for better animal welfare practices and interventions during stressful situations, ensuring the health and safety of the animals involved.
