an excellent source of slowlydegraded protein 4-6 withapproximately 60 percent ofthe protein escaping the rumen7, 8 and passing into thesmall intestine where it isreadily absorbed 9 . For example,the quantity of lysineabsorbed from the smallintestine was similar whenan equal amount of corngluten meal and soybeanmeal protein was fed. Thehigh rumen escape of lysinein corn gluten meal relativeto soybean meal, and highbioavailability of the corngluten meal protein, madethis possible.The potential for corn glutenmeal to improve efficiencyof protein utilization hasbeen demonstrated in thegrowing calf 6 and high producingdairy cow 10, 11 . Corngluten meal in combinationwith other nitrogen sourcesoffers the opportunity toformulate supplementswhich are nutritionallyequal to many natural proteinsupplements, but with aconsiderable cost savings.Corn germ meal has beenshown to be an excellentsource of supplemental fat inbeef finishing diets 12 .Corn steep liquor has beendemonstrated to be a usefulingredient in beef cattle feeding.Up to 15 percent wassuccessfully fed in concentratemixtures for growingcrossbred calves 13 . Adding 5percent steep liquor concentrateto corn forage atensiling significantly increaseddigestibility of drymatter, crude protein, crudefiber and nitrogen-free extract(NFE) with growingcattle 14 . Corn steep liquorwas an effective proteinsource for wintering dry,pregnant cows on nativerange 15, 16 .Dry corn gluten feed pelletsare an excellent source ofprotein, energy and mineralsin beef cattle diets. Corngluten feed, either as dry,wet or ensiled, could be substitutedfor up to 50 percentof the dry matter in highconcentratediets for cattleand sheep, comparing favorablywith corn + urea orcorn + soybean meal diets 17 .High dietary levels (up to 80percent of the diet) supportedcattle gains that werenearly equal to those ofcattle fed corn silage 18 .Growing steers fed cornsilage-based diets supplementedwith dry corn glutenfeed pellets grew faster andrequired less feed per unit ofgain than did those fed asimilar diet supplementedwith soybean meal 19 . Thevery low acid detergent insolublenitrogen values ofcorn gluten feed suggest thatthe crude protein is nearly12
