Fermentability and Degradability of Sheep Ration Containing Sengon Leaves (Albizia falcataria), Jackfruit Leaves (Artocarpus heterophyllus), and Teak Leaves (Tectona grandis)
Abstract
The challenge of providing high-quality and affordable feed for sheep necessitates the use of locally available feed resources with high nutritional value. This study investigated the in vitro fermentability and degradability of sheep rations containing jackfruit (Artocarpus heterophyllus), sengon (Albizia falcataria), and teak (Tectona grandis) leaves. A completely randomized design (CRD) with three dietary treatments and six replications was applied: P1 = 30% jackfruit leaves + 70% Odot grass, P2 = 30% sengon leaves + 70% Odot grass, and P3 = 30% teak leaves + 70% Odot grass. The in vitro method followed Tilley and Terry (1969). Data were analyzed using ANOVA, followed by Duncan’s multiple range test. All observed parameters were significantly affected (P < 0.05), including total volatile fatty acids (VFA), ammonia (NH₃) concentration, dry matter degradability (DMD), and organic matter degradability (OMD). The P1 treatment yielded the highest results: VFA (170.74 mM), NH₃ (6.46 mM), DMD (62.87%), and OMD (58.52%). These findings suggest that jackfruit leaves have strong potential as an alternative feed ingredient for improving the fermentation characteristics and digestibility of sheep rations.
