Soybean meal in tilapia diets

Chinese scientists studied the effects of different levels of soybean meal inclusion in replacement for fish meal on growth, digestive enzymes and transaminase activities in practical diets for juvenile tilapia. This study evaluated the effects of replacing fish meal (FM) in practical diets for tilapia (Oreochromis  niloticus x O. aureus) with different levels of soybean meal (SBM) on growth, digestive enzymes and liver transaminase activities.

Five isonitrogenous (crude protein 300 g/kg) and isoenergetic (gross energy 16 kJ/g) practical diets were formulated by replacing zero (the control), 25, 50, 75 and 100 percent of protein from fish meal with SBM. Each diet was randomly assigned to triplicate groups of 30 fish per aquarium (mean initial weight 4.0 g). Fish were fed three times daily to apparent satiation for eight weeks. Read more ...
