Resumo: | Dinomys branickii is a large rodent listed as Endangered (EN), that suffers pressure from anthropogenic activities such as hunting and habitat destruction. Captive breeding methods are viable for supplementation of conservation projects, and may enhance our knowledge of main aspects of the biology of this species. The objective of this study was to determine consumption and food preferences in a captive group of D. branickii. To determine feeding preferences, the Food Preference Index (P) was used for the type of food with highest consumption. The mean amount of food provided was 6.6 kg per day per group, with 4.4 kg per day/group consumed (66%). An average of 11 ± 2.9 types of food were offered daily. The consumption of fruits (71%) was higher than the consumption of other food groups, followed by roots/tubers (65.3%). The food groups least consumed were cereals and seeds (39.4%) and leaves (38.3%). The preferred foods were: Brassica oleracea (P = 1.38), Zea mays (P = 1.25), Ipomoea batatas (P = 1.17), Mangifera indica (P = 1.13), Cucurbita moschata (P = 1.10), Talinum esculentum (P = 1.00) and Manihot esculenta (P = 1.00). These results suggest that foods with high fiber and carbohydrate content are the best choices for D. branickii development and well-being in captivity. |

A criação dessa espécie em cativeiro é uma alternativa viável para a implantação de projetos de conservação e para ampliar o conhecimento dos principais aspectos da sua biologia. O objetivo deste trabalho foi determinar o consumo e a preferência alimentar de um grupo de D. branickii em cativeiro. Para determinar a preferência alimentar foi utilizado o índice de preferência alimentar (P) dos alimentos mais consumidos. A quantidade média de alimentos ofertados foi de 6,6 kg dia/grupo, sendo consumidos 4,4 kg dia/grupo (66%), totalizando 11 ± 2,9 alimentos ofertados por dia. O consumo de frutas (71%) foi maior que os demais grupos alimentares, seguido do consumo raízes/tubérculos (65,3%) e os menos consumidos foram cereais/sementes (39,4%) e folhas (38,3%). Os alimentos preferidos foram: Brassica oleracea (P = 1,38), Zea mays (P = 1,25), Ipomoea batatas (P = 1,17), Mangifera indica (P = 1,13), Cucubita moschata (P = 1,10), Talinum esculentum (P = 1,00) e Manihot esculenta (P = 1,00). Os resultados obtidos sugerem que os alimentos com teor elevado de ibras e carboidratos devem ser utilizados na composição da dieta de D. branickii em cativeiro, visando o bem estar e desenvolvimento da espécie.
