Palm kernel

Palm kernel within a palm fruit.

The palm kernel is the edible seed of the oil palm fruit. The fruit yields two distinct oils: palm oil derived from the outer parts of the fruit, and palm kernel oil derived from the kernel.[1]

The pulp left after oil is rendered from the kernel is formed into "palm kernel cake", used either as high-protein feed for dairy cattle or burned in boilers to generate electricity for palm oil mills and surrounding villages.

Uses

Palm kernel cake

Palm kernel cake is most commonly produced by economical screw press, less frequently via a more expensive solvent processes.[2]

Palm kernel cake is a high-fibre, medium-grade protein feed best suited to ruminants.[3][4] Among other similar fodders, palm kernel cake is ranked a little higher than copra cake and cocoa pod husk,[5] but lower than fish meal and groundnut cake, especially in its protein value.

Composed of 16% fiber, palm kernel cake also has a high phosphorus-to-calcium ratio and contains such essential elements such as magnesium, iron and zinc.[6] The typical ration formulated for the feeding of dairy cattle consists of palm kernel cake (50%), molasses (5%), grass/hay (42%), limestone (1.5%), mineral premix (1%) and salt (0.5%) and trace element/vitamin premix.[7]
