Composed of 16% fiber, palm kernel cake also has a high phosphorus-to-calcium ratio and contains such essential elements as magnesium, iron, and zinc. 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%), with trace element/vitamin premix.
