What is the term for the sudden death of heavily muscled hogs?

1. Porcine Stress Syndrome

2. Swine Flu

3. Hog Cholera

4. Iron Deficiency

The correct answer is: Porcine Stress Syndrome

The sudden death of heavily muscled hogs is referred to as Porcine Stress Syndrome (PSS). This condition is often caused by a genetic predisposition that leads to heightened sensitivity to stress. When these hogs experience stress from handling, transportation, or environmental changes, they can undergo physiological reactions that result in increased heart rate and body temperature, leading to death. PSS is particularly notable in certain breeds of swine, such as the Pietrain, which are known for their extreme muscularity and can be more susceptible to stress-related issues. Management practices that reduce stress and careful breeding strategies are essential to mitigate the risks associated with this syndrome. Other terms mentioned, like Swine Flu and Hog Cholera, refer to viral diseases that affect pigs, while Iron Deficiency is a nutritional condition that affects young pigs and doesn't lead to sudden death in heavily muscled hogs. Thus, understanding PSS is vital for livestock producers aiming to minimize losses in their herds.
