ABSTRACT
Browse plants and grass with varying level of secondary compounds were offered to 3-6 months old goats fed diet based on napier grass and pellet. The fermentability (gas production Menke method) was measured after 3 days of adaptation at fed napier grass and the effects on fed first was evaluated for the next 12 weeks. Napier grass average was gas production (GP), degraded in vitro and degraded in sacco (50.1 ml, 41.9 % and 48.7 %) respectively for control animals (Table 2), and browse plant ranged between (10.3–64.4 ml GP, 27.3–70.9 % in vitro and 29.7–90.5 % in sacco) respectively. For added PEG in browse plant increase percentase degraded between 25.7–64.2 ml GP, 34.2–75.0 % in vitro) respectively for treated animals. L. leucocephala was better fed degraded for nutrition animal, but 2nd hight degraded in sacco (79.8 %) and A. heterophyllus (73.0). Effect Polyetylene Glycol (PEG) in degraded fed L. leucocephala was increase until 50.5 %. Partitioning factor (PF) fed from browse plant M. esculenta can be decrease Partitioning (PF) to 92.3 % and low at C. odorata (0.8 % only). Treatment added Catechin and PEG to straw the result hight GP, digested and PF in the straw only and added PEG. Catechin hight level was not increase GP and digested. In these experiment browse plant higt GP and digested and low PF and grasses for the GP and digested low, increase PF. Browse plant L.leucocephala has Hiht tannin (TEPA 264.8 mg/g DM) , but can still with higt digested and GP. In thses case effect tannin fed for animal not yet decrease quantity GP and digested.
