metabolizable energy (ME)of corn gluten meal is alsohighly digestible 61 .Corn gluten feed can be substitutedfor 15 percent of thecorn and soybean meal inbalanced diets of layinghens, without decreasingfeed efficiency or egg production62, 63 . Some studieshave demonstrated that ashigh as 20 percent corn glutenfeed could be included inlayer diets without a negativeimpact on economicproduction 64 . Recent researchshows that the metabolizableenergy value ofcorn gluten feed for broilerscan be as high as 2.8 to 3.1Kcal/g, which is muchgreater than the 1.8 Kcal/g inthe 1994 NRC requirementsfor poultry 56, 65 .With the rapid expansion ofthe turkey industry, there isconsiderable opportunity tomake efficient utilization ofcorn gluten feed in turkeyproduction. Turkey poultscan effectively utilize 10-20percent corn gluten feedwhen diets are balanced tobe isocaloric andisonitrogenous to typicalcorn-soy basal diets 66 .Corn germ meal is an excellentsource of amino acidsfor poultry due to the desirablebalance of essentialamino acids and its highenergy content. Up to 22percent corn germ mealcould be successfully used inbroiler diets 67 while the inclusionof up to 50 percentcorn germ meal in layerdiets did not affect the performance,internal egg qualityor egg shell quality 68 .Dried corn steep liquor concentrateis a useful productin diets for broilers 69-72 , layinghens 73 and turkeys 73 .Inclusion of corn steep liquorconcentrate in layerdiets results in an improvementin internal albumenquality as indicated by increasedHaugh units 73, 74 thatmay be economically beneficialin older hens whereinterior egg quality typicallydeclines.SwineThe first trial evaluatingcorn wet milled feed productsfor swine was conductedin 1920 75 . Since thattime, our understanding ofthe pig’s nutrient requirementsand the ability of cornwet milled feed products tomeet these requirements hasbecome much more sophisticated.Corn germ meal hasbeen shown to be equal tosoybean meal as a proteinsource for the growing pig 76 .Defatted corn germ meal hasbeen demonstrated to beeffective in diets for growingand finishing pigs at levels of16
