How does the vicuna digestive system function regarding high-fiber forage?

Answer

It is adapted to slowly break down tough, high-fiber material

As a member of the camelid family, the vicuña possesses a digestive tract specifically evolved to process coarse, high-fiber forage. Unlike Old World ruminants, which may have different digestive efficiencies, the vicuña's system is highly effective at extracting nutrients from the tough, fibrous grasses of the puna. This physiological specialization allows the animal to survive and thrive on vegetation that would be largely indigestible to many other herbivores.
