Abstract
The chemical composition and in vitro digestibility (IVD, pepsin/pancreatin) of foliages from carob (Albizia lebbek), gliricidia (Gliricidia sepium), guásima (Guazuma ulmifolia), hibiscus (Hibiscus rosa-sinensis) and mulberry (Morus alba) were determined. Overall, IVD of DM and organic matter was in the range of 30.6-48.0% and 33.3-46.7% respectively. The range for IVD of N was rather higher, between 45.6 and 65.5%.Guásima showed the lowest values (2.29 and 45.6% respectively) for N content and in vitro N digestibility in spite of their similar or even highest concentration of crude fibre and neutral detergent fibre concentration as compared to gliricidia and carob. In vitro dry matter and organic matter digestibility were higher in gliricidia (48.0 and 46.7 % respectively) and hibiscus (46.6 and 33.3% respectively). However, in terms of in vitro N digestibility, gliricidia and hibiscus were not significantly better than carob. Crude fibre and neutral detergent fibre had a negative influence on dry matter and organic matter digestibility. It was not found any significant interdependence between N in vitro digestibility and the fibre level probably due to the dependence of the N linked to fibre in the examined
