Determination of dry matter digestibility in “sagüis de tufo preto” (Callithrix penicilatta) and “macacos-prego” (Cebus apella)

Foi determinado o Coeficiente de Digestibilidade Aparente da Matéria Seca, em rações para animais silvestres. Foram utilizados 16 animais, oito (8) sagüis de tufo preto (Callithrix penicilatta) e oito (8) macacos-prego (Cebus apella). Os animais foram mantidos em gaiolas de digestibilidade e receberam a ração básica durante 10 dias. Após o período inicial, as amostras de fezes foram colhidas durante 5 dias para posterior análise. Os Coeficientes de Digestibilidade para o Callithrix estiveram entre 84,9 e 97,7%, enquanto para o Cebus oscilaram entre 75,4 e 86,2%. A pesquisa concluiu que as rações utilizadas foram muito bem aproveitadas pelos animais.Applicability of the total collection of faeces, for determination of apparent digestibility of dry matter, was studied in nonhuman primates - Callithrix penicilatta eight (8) and Cebus apella eight (8). Animals were maintained in individual boxes where they received the ration for ten days. All of the feed offered and any refused was weighed and recorded. After an initial period, the samples of the faeces were collected for five days and analyzed. The apparent digestibility coefficient varied from 84.9 to 97.7% for C. penicilatta and from 75.4 to 86.2% for C. apella. The research concluded that the tested rations conveniently fed the animals
