PKE is a by-product of the palm oil industry in South East Asia. It is derived from the nut of the palm fruit after the oil is mechanically extracted. This feed is a dry gritty meal with a soapy smell and has low palatability.
However, PKE has reasonable levels of energy (ME) and protein, and is relatively easy to introduce to cows over a range of farm systems. The profitability of PKE is dependent on the price of PKE relative to payout and the utilisation of PKE and pasture.
