摘要

This experiment was conducted to examine the utilization of defatted soybean meal (SBM) as a fish meal (FM) substitute in the diets for giant gouramy Osphronemus gouramy Lac. The levels of substitution of FM by SBM were 0, 25, 50, 75 and 100% of dietary protein, respectively. The diets were isoenergetic, isonitrogenous and isolipid. Daily growth rate. feed efficiency, protein and lipid retention, apparent digestibility of protein, lipid and carbohydrate, ammonia excretions and respiratory quotient were used as parameters to evaluate the differences among treatments. A substitution level of 50% resulted in the highest daily growth rate, feed efficiency, and protein and lipid retention (p <0.05). This treatment also resulted in the lowest nitrogen excretion. Digestibility of protein, lipid and carbohydrate decreased with an increase in SBM, due to the increase in fiber content and insoluble carbohydrate. The respiratory quotient of the experimental fish ranged from 0.85 to 0.99, indicated that both protein and carbohydrate were catabolyzed as the main sources of energy. Based on the evaluation of these parameters, it is concluded that SBM can substitute 50% of the protein for FM in the diets of giant gouramy without impairment of performance.
