Evaluation of Cuphea Meal as an Ingredient Replacement in Channel Catfish, Ictalurus punctatus, Diets Academic Article uri icon

abstract

  • Cuphea meal is a new, alternative feedstuff that has potential as a sustainable, economical replacement for wheat, rice, and corn ingredients in channel catfish, Ictalurus punctatus, diets. Channel catfish fingerlings were fed a control diet containing wheat or two experimental diets containing 7.5% cuphea meal, or 12.5% cuphea meal for eight weeks to determine if cuphea meal could replace wheat products in catfish diets. Mean (SE) weight gains were 317.8 28.8 g, 407.0 36.9 g, and 372.8 29.8 g for fish fed the control diet, the 7.5% cuphea meal diet, and the 15% cuphea meal diet, respectively, and there were no significant differences (P < 0.05) among treatments. Mean (SE) whole-body protein of fish fed the cuphea diets (13.3 0.66 and 14.5 0.21%) was significantly (P < 0.05) higher than that of fish fed the wheat diet (12.7 0.44%). Cuphea meal enhanced body composition of juvenile channel catfish without affecting growth or survival. Therefore, cuphea meal is a promising candidate for replacement of wheat bran at the levels tested. 2007 The Haworth Press, Inc. All rights reserved.
