A study was made of different ways of offering Jackfruit foliage [Artocarpus heterophyllus] to goats. The feeding methods were: fresh leaves in the feed trough (L), the whole branch hanging from the roof of the pen (B) or foliage hanging  plus leaves in the feed trough (BL).  The experimental design was a 3*3 Latin square arrangement with 3 goats and 3 periods each of 7 days.] DM and crude protein concentrations were higher in leaves than in the foliage (leaves plus stems). The goats ate more DM when they were offered the foliage hanging from the roof of the cage (486 g DM/d). Intake was lowest and eating time longest when only the leaves were offered in the feed trough (282 g DM/d). DM and OM digestibility and N retention followed the same pattern as DM intake, with highest values for hanging foliage and lowest for leaves fed separately.  There was no effect of feeding method on rumen pH and rumen ammonia levels which ranged from 130 to 310 mg/litre. It is concluded that dry matter intake, digestibility and N retention of jackfruit by goats is higher when the leaves are attached to the stem and hung from the walls of the pen, compared with putting only the leaves in a feed trough
