Abstract: The experiments were carried out to evaluate the protein-sparing effect in Heteropneustes fossilis fry (0.751 ± 0.01 g) fed for 90 days with six isocaloric diets containing 45, 40 or 35% of casein-protein and 25, 30 or 35% of glucose/dextrin, combined properly as the work purpose.The highest weight gain was recorded in fry fed with 35% dextrin and 35% crude protein level.Interestingly, the value of SGR (2.950±0.017)and PER (1.793±0.03)were significantly (p<0.05)increased with reducing protein level from 45 to 35% and with increasing carbohydrate level from 25% to 35%, respectively.However, the poorest growth was recorded in the fry fed with glucose containing diets than dextrin-containing diets.Protein deposition was significantly (p<0.05)lower in fry fed with the glucose diets at the protein level of 45% than those fed with 40 or 35%, indicating that H. fossilis utilize dextrin easily than glucose.Increase of dextrin content from 35 to 45% did not reduce (p<0.05) the weight gain, even reducing the dietary protein from 45 to 35%.This fact suggests that carbohydrate spare protein by using dextrin as energy source.
