Effect of Fish Oil Substitution with Sunflower Oil in Diet of Juvenile Catlacatla (Ham) on Growth Performance and Feed Utilization
2015
During the present investigation Catla catla fry (0.250 ± 0.008 g) were fed with five iso-nitrogenous (40%) and isolipidic (6%) diets in triplicate @ 5% of body weight, for a period of 60 days. Diet A1 (control)was without supplemented oil i.e., whereas diets A2-A5were supplemented with 3% fish oil (FO) and sunflower oil (SFO) at different proportions i.e. diet A2 with(100% FO), diet A3 (70% FO+30% SFO), diet A4 (50% FO+50% SFO) and diet A5 (70% SFO+30% FO). After the end of 60 days of feeding trail a significant difference (p 0.01) in all the growth performance parameters between oil supplemented diets i.e. A2-A5. However, diet A1 (control) registered poorest performance i.e. 42.54% (WG), 0.271 (SGR), 7.75 (FCR), 12.88 (FCE) and 93.56% survival rate. The present result thus clearly revealed that sunflower oil could be partially replace the fish oil up to 50% in supplemented diet without any adverse effect on the growth performance of Catla catla fry, as it is less expensive and easily available.
