| 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 replicates per treatment, 16 adult female capybaras were fed isocaloric diets containing four levels of nitrogen (11.4, 12.3, 15.4 and 18.4 g N/kg dry matter-DM); calcium (3.0, 3.5, 4.0 and 4.5 g Ca/kg-DM); and phosphorus (2.0, 2.3, 2.7 and 3.0 g P/kg-DM). After 10 days of adaptation, the collection of feces was carried out for five consecutive days. Immediately following fecal collection, the animals were housed in metabolic cages for two days for urine collection.... |

| Five pen-raised adult female capybaras were used in five digestibility trials in a Latin square design, to determine, for capybaras, the nutritional values of Cameroon grass (Pennisetum purpureum cv. Cameroon); Napier grass (P. purpureum cv. Napier); corn grain; cassava hay, comprising leaves and stems; and palm kernel (Elaeis guineensis) cake. These feedstuffs were provided separately or mixed, in a completely randomized manner, in different experimental periods. The digestibility of each feedstuff not supplied alone was estimated by difference. The animals were individually introduced in metabolism pens. Following a 10-day period of adaptation to each diet, feed intake was recorded and total fecal output was collected over five consecutive days. Energy,... |
