| Popis: | Corn gluten meal, corn gluten feed, and corn distillers' grains with solubles, the coproducts from ethanol fermentation of corn, were incorporated in tilapia diets with 32 and 28% protein. The diets were balanced in amino acid composition by addition of soy flour and/or synthetic lysine and tryptophan. The diets were fed to tilapia fry of average initial weight of 0.5 g in aquaria for 8 weeks. Weight gain expressed as percentage increase after 56 days were best (P 0.05) as the control 32% protein diet. Fish fed 28% protein diet with 82% corn distillers' grains with solubles and synthetic lysine and tryptophan and 28% protein diet with 67% corn gluten feed and 26% soy flour also resulted in the same feed conversion ratio and protein efficiency ratio (P > 0.05) as the control diet. Fish fed the remaining two 28% protein diets exhibited higher feed conversion ratio and lower protein efficiency ratio (P < 0.05) than fish fed the control diet. It appears the 28% protein diet with 67% corn gluten feed and 26% soy flour is adequate for tilapia fry based on weight gain, feed conversion ratio, and protein efficiency ratio. |
