Abstract: Palm press fibre (PPF) was obtained from two sources, a small-scale oil palm processing unit and a large-scale factory processing unit, and its chemical composition was determined. In vitro digestibility techniques were used to assess the feeding value of untreated, defatted and sodium hydroxide-treated PPF. For the NaOH treatment, 0.5 g oven-dried PPF was treated for 24 h with 5"., NaOH in three ways: treated and not washed (NaNW): treated and washed (NaW): and treated after milling (NAD). The results indicate that, on a dry matter basis. PPF is low in nitrogen ( 12 1 3 g/kg), moisture (37- 90 g/kg) and ash (53-62 g/kg), but high in ether extract (269-355 g/kg), neutral detergent fibre (532- 768 g/kg), acid detergent fibre (375-548 g/kg) and lignin (219 g/kg). The in vitro dry matter digestibility values were low for the samples from both sources, but the large-scale factory-processed I'PF had higher in vitro dry matter digestibility (0.215 vs 0.166) and in vitro organic matter digestibility (0.196 vs 0.145). Defatting the PPF and treating it with 5`Y, NaOH solution significantly (p 11.01) improved both the dry matter and organic matter digestibility. Washing the NaOH-treated PPF resulted in a higher digestibility of dry matter as against NaNW or NAD. These results suggest that dclaning and treatment with 5% NaOH would improve the feeding value of PPF.
