Digestive physiology of captive capybara (Hydrochoerus hydrochaeris)

The capybara (Hydrochoerus hydrochaeris), the largest living rodent, probably has a “mucus-trap” colonic separation mechanism. To test this hypothesis, we measured the mean retention time of a solute marker (MRTSolute), 2 mm (MRT2 mm), 10 mm (MRT10 mm), and 20 mm (MRT20 mm) particle markers and nutrient digestibility in adult captive capybaras (27–52 kg body mass (BM), 2–11 yr). In addition, total […]
