Improved ruminant feeds are provided which include a pH-adjusted first ingredient selected from the group consisting of ruminant-edible, initially low pH commercial byproducts and initially low pH grain or forage-derived products, combined with a second ingredient comprising a high digestive efficiency feed grain such as flaked corn. An improved process ( 10 ) for the production of a ruminant feed ( 50 ) as an adjunct to a fuel ethanol plant is also provided wherein starch-bearing grain ( 12 ) is processed to yield ethanol ( 30 ) and whole stillage ( 32 ). The whole stillage ( 32 ) is then treated to remove water and to yield a wet distiller's grain product (WDG) ( 38 ). The pH of the WDG ( 38 ) is then elevated ( 46 ) by the addition of base to a pH of from about 5-8, and the pH-adjusted WDG ( 46 ) is optionally dried ( 47 ) and combined with a high digestive efficiency feed grain (HDEG) such as flaked grain ( 48 ). The ruminant feeds ( 50 ) of the invention do not generate low rumen pH levels when consumed, and thus avoid rumen acidosis and related problems.
