A ruminant animal feed comprising whole linty cottonseed and preferably soybeans. The soybeans may be replaced by other oil bearing grains and additional nutrients may be added to the feed. The feed includes the lint of the cottonseed for providing fiber to the animals and has a reduced gossypol content as compared to whole raw cottonseed. A process utilizing an auger extruder is used to work the mixture of cottonseed and soybeans to heat the mixture and thereby cook it without charring the mixture. Subsequent to cooking the mixture is extruded and cooled for forming a meal that is provided to the animals for feed.
