The by-product obtained after the extraction of kernel oil from palm oil kernels is called plam kernel cake (PKC) or palm kernel expeller meal (PKE). The product is a valuable source of energy for ruminants and has been used widely in rations for beef and dairy cattle, goats and sheep but its use in poultry rations is constrained by its high fibre content. Traditionally PKC is used in poultry diets at inclusion levels of 10-15 % percent. With improvement in extraction methods and reduction in shell content PKC can be included at levels higher than 30 % in broiler and layer rations. Studies on Muscovy ducks have shown that ducks were able to utilize PKC better than broiler chickens. Current studies are focused on the methods of reducing fibre content in PKC through enzyme treatment and solid state fermentation (SSF). Aspergillus niger has been identified as a useful organism in increasing the crude protein content of PKC through SSF. These methods are potentially useful in reducing the crude fibre content, subsequently increasing the digestibility and availablity of protein.
