The present study was conducted to investigate the impact of different percentages of animal and plant origin dietary lipids level on growth performance and body composition of major carps. Four plant and animal origin fats supplemented experimental diets of different levels of lipids viz. 0%, 3%, 6% and 9% were made. Twenty-one treatments were made with different levels of animal, plant and combination of animal and plant dietary lipids, where twenty fingerlings were stock in each experimental tank. Animal-based saturated (ABS), unsaturated (ABUS), plant- based monounsaturated (PBMU), polyunsaturated (PBPU) and the combination diets were prepared using different percentages of animal and plant based dietary lipids. Growth performance (weight gain, total length and fork length)and food conversion ratio was recorded monthly. The body composition in terms of crude protein, crude ash, crude fat and moisture were determined. Results showed that weight gain, total length and fork length in cirrhinus mrigalawas significantly higher as compared to other two carp species.Significant (p < 0.05) increase in both parameters at 6% and 9%dietary lipid levels as compared to the fish fed on 0% and 3%. The Cirrhinus mrigala showed significantly higher crude protein in 6% ABSdietary lipidsfollowed by Labeo rohita and Catla catla. The significant higher moisture content and crude ash were recorded in L. rohita in 3% ABUS and 9% animal and 6% plant dietary lipids,whereas, C. catla showed the significant higher crude fat contents in 9% ABUSdietary lipids.In conclusion, C. mrigala shows significant improvement in growth performance. Similarly, fishes fed on animal-based dietsand in combination diet, showed consistently significant (p < 0.05) increase in crude protein, crude fat,moisture and crude ash with the increasing levels of dietary lipids from 0 to 9%.
