The objective of the present study was to evaluate the in vitro and in situ dry matter degradation by including cacay cake ( Caryodendron orinocense ) on a diet based on Brachiaria dictyoneura . The experiment was developed in an animal nutrition laboratory on the Animal Sciences Faculty at the Universidad de Ciencias Aplicadas y Ambientales, Bogotá, Colombia, in July 2015. Four treatments were evaluated: B. dictyoneura , cacay cake and two mixtures of B. dictyoneura : cacay cake (80:20 and 60:40). The chemical composition and the in vitro and in situ degradability of the dry matter and the crude protein, at 48 hours were determined. The variables were analyzed through a complete randomized design with four treatments. The inclusion of cacay cake decreased the cell wall-associated with carbohydrate concentration and increased the higher digestibility nutrients; the crude protein and dry matter, in situ and in vitro degradability increased 22, 6 and 38%, respectively. In conclusion, the inclusion of cacay cake on a diet of B. dictyoneura improves dry matter degradation in vitro and in situ conditions.
