Abstract
Ten semi-purified diets with two levels of dietary protein (32 and 41%) having five energy
levels each (324, 341, 364, 384 and 407 kcal.lOOg1) were formulated and fed to Labeo rohita
fingerlings for a period of 45 days. Factorial analysis of variance indicated that although
weight gain, food conversion efficiency and protein utilization were significantly affected by
dietary energy and protein levels, the energy and protein conversion efficiencies were not
influenced by dietary energy and protein interaction. The best growth and food conversion
ratio (FCR) were obtained with an average of 379.72 kcal.lOOg1 at 41% protein diet (P/E
107.87 and E/P 9.29), while maximum protein utilization and conversion occurred with similar
energy levels (383 kcal.lOOg"1) but in low protein (32%) diet. Although dietary energy
influenced the body constituents of fish, the influence of protein was not significant. The
results indicated that with increased allowance of energy, more protein was utilized for tissue
building and enhancement of growth.
