Experimental diets containing 32-40% protein and 16-49% corngluten meal, corn gluten feed, orcorn distillers' grains with solubles were fed to tilapia with 0.4 ginitial weight for 8 weeks in aquaria.Weight gain, feed conversion ratio, and protein efficiency ratiofor experimental and control dietswere in the range of 3270-5320%, 1.06-1.38, and 1.87-2.37,respectively. Statistically, the highestweight gain was achieved from control diet and a 40% protein diet with35% corn distillers' grainswith solubles; the best feed conversion ratio was obtained from controldiet and two 40% proteindiets with 35% corn distillers' grains with solubles or 30% corngluten feed; the highest proteinefficiency ratio was from control diet and two 36% protein diets with49% corn distillers' grainswith solubles or 42% corn gluten feed.Keywords: Tilapia; corn gluten meal; corn gluten feed; corn distillers'grains with solubles
