What is the primary concern when a pig is frightened or startled?

The primary concern when a pig is frightened or startled is that it can easily become overheated. Pigs have a limited ability to regulate their body temperature, particularly in stressful situations. When a pig is scared, it may exhibit increased activity and agitation, which can lead to elevated body temperature. Unlike many other animals, pigs do not sweat effectively to cool themselves down. This makes it crucial to monitor their temperature and environment when they are in a state of fear or stress, as overheating can lead to severe health issues.

Understanding the physiological responses of pigs to stress is essential for effective animal welfare management. A pig's natural behavior when frightened does involve various responses, but the risk of overheating due to their unique anatomical and physiological characteristics remains a significant concern for their health and safety.
