Protein, calcium and phosphorus requirements in the maintenance of captive-bred capybaras
The objective was to determine the nitrogen-protein, calcium and phosphorus requirements of adult capybaras (Hydrochoerus hydrochaeris) bred in captivity through a nutritional balance study under conditions that favored the occurrence of cecotrophy. In a completely randomized design with four replic...
