Objective of this study was to determine the digestibilities of leucaena and kenaf foliages using nylon bag and mobile bag technique. There cattle with an average 314+-14 kg each fitted with a permanent rumen and a T-shape duodenum cannulae were used. Ruminal DM and CP disappearances increased with rumen incubation time for all feedstuffs. Dry matter degradation rates of kenaf foliage was significantly higher (p0.05) than leucaena foliage, especially in 24 hr after incubation time. The loss of DM by washing of kenaf foliage was higher than leucaena foliage. Similarly, the loss of CP by washing of leucaena foliage were higher than kenaf foliage, and degradability of water insoluble fraction of kenaf foliage was higher than leucaena foliage. The potential degradation and the effective degradability of DM and CP for kenaf foliage was high than leucaena foliage. Intestinal DM and CP disappearance leucaena foliage was significantly higher (p0.05) than kenaf foliage.
