Effect of Dietary Lipid Levels on Growth, Feed Conversion, and Muscle Composition of the Walking Catfish,Clarias batrachus

摘要: Feeding trials were conducted to determine the feasibility of using spray-dried blood meal (EM) or enzyme-hydrolyzed (EH) and low-ash (LA) poultry products partially replace fish (FM) in diet formulations for palmetto bass. Pelleted diets formulaled with EM protein replacing 10, 25, 50% FM either EH LA approximately 50, 75% protein. All formulated contain 14kJ GE energy/g 35% crude Fish fed a die1 which BM replaced supplied by had significantly (P < 0.05) lower weight gain feed efficiency compared control at end 6 12 weeks. Total body lipid was higher those receiving 10 25% BM. However, there no differences total moisture, protein, ash. When rep
