How many quadrants must a veterinarian listen to when examining a horse's gut motility and function?

When examining a horse's gut motility and function, a veterinarian must listen to all four quadrants of the abdomen. This thorough examination is necessary to assess the gut sounds and movement in different areas, which can give important indicators about the overall gastrointestinal health of the horse. Each quadrant represents a different section of the digestive tract, and monitoring them all can help in diagnosing potential issues such as colic or other gastrointestinal disorders. Listening to all four quadrants ensures that the veterinarian gains a comprehensive understanding of the horse's gut status, allowing for more effective treatment and management decisions.
