Abstract

A newly developed biphasic feed lipid extraction procedure has increased accuracy relative to Goldfisch ether extraction, especially for condensed corn distillers solubles samples. A pre-NDF fat extraction must be completed prior to analyzing high fat feeds for NDF. Corn should be ground through a 1-mm screen on a Tecator Cyclotec sample mill to accurately determine corn NDF content.
