What are two common causes of thrush in horses?

Thrush is a common condition in horses that affects the frog of the hoof, often characterized by a foul odor and black, mushy tissue. Understanding its causes is crucial for effective prevention and treatment.

The correct answer identifies poor hoof hygiene and wet conditions as two common causes of thrush. Poor hoof hygiene allows for the accumulation of dirt and debris, which can harbor bacteria and fungi. When hooves are not cleaned regularly, especially in damp environments, the conditions become favorable for pathogens that contribute to thrush.

Wet conditions significantly exacerbate this issue. When horses are in muddy or wet environments, their hooves remain moist for extended periods. This prolonged dampness softens the frog and other hoof structures, creating an ideal environment for the proliferation of harmful microorganisms.

On the other hand, options that suggest other combinations, such as dry conditions in conjunction with poor hoof hygiene or high sugar diets, do not align with what is commonly accepted as a primary cause of thrush. In fact, dry conditions are less likely to contribute to thrush since they do not support the moisture needed by bacteria and fungi to thrive. Similarly, while nutrition and hoof care are important for overall hoof health, they do not directly correlate with the specific conditions leading to thr
