Which nutritional disorder impacts the respiratory system of horses?

1. Ketosis

2. Heaves

3. Anhydrosis

4. Obesity

The correct answer is: Heaves

Heaves is accurately identified as the nutritional disorder that impacts the respiratory system of horses. This condition, also known as recurrent airway obstruction (RAO), is characterized by inflammation of the airways and increased respiratory effort. It often arises in horses that are exposed to allergens or irritants found in certain feeds, bedding, or environmental conditions, leading to chronic coughing, difficulty breathing, and exercise intolerance. Heaves is particularly associated with horses that consume dusty hay or have other nutritional factors that contribute to airway irritation. Management typically involves dietary adjustments, such as providing low-dust forage and minimizing exposure to triggers, which can help reduce the severity of the symptoms. This highlights the connection between nutrition and respiratory health in horses. Other conditions listed, while they may have their own impacts on health, do not directly affect the respiratory system in the same way that heaves does.
