Experiment was conducted to evaluate the effect of different levels of Arachis pintoi (AP) supplementation on rumen environment (rumen pH, ruminal ammonia nitrogen (NH3N) and volatile fatty acids (VFAs) concentration) and degradability of oil palm frond (OPF). Three Kedah-Kelantan (KK) cattle of about 2 1/2 years of age with and average body weight (BW) 173 +- 17.2 kg, each fitted with a ruminal cannula, were used. The cattle were kept in individual pens and fed the treatment diets at 1.5 percent of BW. The diets comprised the following four OPF:AP ratios: 80:20 (L20), 70:30 (L30), 60:40 (L40), 50:50 (L50) in a 4*4 incomplete Latin Square Design. The DM an NDF degradation rates of OPF were significantly affected by AP supplementation. Ruminal pH was not significantly different (p0.05) among the four different diets. The concentration of NH3N was significantly (p0.05) higher in cattle fed L50 than those in L40, L30 and L20. Similarly, increasing levels of AP supplementation significantly increased the total VFAs concentration from 59.9mmol/L for L20 to 69.2 mmol/L for L50. It is suggested that AP can be used as a protein supplement to improve fibre degradability of OPF in cattle.
