The present study was undertaken to assess the bioaccessibility of major minerals (Ca, P and Mg) from mustard, cottonseed and maize germ oil cakes in ruminant rations using three-stage in vitro technique. Rumen liquor was collected from three male fistulated Karan-Fries calves. Release of P and Mg from oil cakes was the highest (P<0.05) at intestinal stages but for Ca, it was highest at abomasal stage. Bioaccessibility of all the nutrients were significantly (P<0.05) higher in mustard cake followed by maize germ oil cake and cottonseed cake.
