The effect of Napier grass and oil palm frond (OPF) supplemented with soya waste on the intake and growth performance of goats was evaluated. Twelve female cross-bred goats (Boer × local) were divided into three groups and randomly assigned to three experimental diets: (1) Napier grass ad libitum (NG), (2) OPF ad libitum (OPF) and (3) Napier grass ad libitum+ OPF ad libitum (NG-OPF). All goats in each group received soya waste at the rate of 1.3% of their body weight (BW). Dry matter intake per kg unit of BW was higher (P < 0.05) in the NG-OPF diet than in the NG or OPF diets. However, the crude protein intake per kg unit of BW was higher (P < 0.05) in the OPF or NG-OPF diet than in the NG diet. Animals on the OPF diet showed a lower (P < 0.05) daily BW gain followed by the animals on the NG and NG-OPF diets, but no variation (P > 0.05) was observed between the animals on the NG and NG-OPF diets. The results showed that the feeding of NG alone or NG-OPF combination to goats could lead to a better growth rate in these animals compared to feeding them with OPF alone.
