Ruminal and intestinal digestibility of Leucaena (Leucaena leucocephala) and jack fruit (Artocarpus heterophyllus) foliages using in sacco and three-step techniques

Abstract

The objective of this study was to determine the digestibility of Leucaena and Jackfruit foliages using nylon bag technique. Three crossbred (Thai native × Anglo-Nubian) goats with an average 16±1.3 kg each fitted with a permanent rumen were used. Ruminal DM and CP disappearances increased with rumen incubation time for all feedstuffs. Dry matter degradation rates of Jackfruit foliage was significantly higher (p<0.05) than Leucaena foliage. The loss of DM by washing of Jackfruit was higher than Leucaena foliage. Similarly, the loss of CP by washing of Leucaena foliage was higher than Jackfruit foliage and degradability of water insoluble fraction of Jackfruit foliage was higher than Leucaena foliage. The potential degradation and the effective degradability of DM and CP for Jackfruit foliage were high than Leucaena foliage. © Medwell Journals, 2011.
