Effect of dietary digestible energy level on growth indices of kutum (Rutilus frisii kutum Kamenskii, 1901)
چکیده:   (2912 مشاهده)
A 60-days feeding trail was conducted to evaluate the effects of dietary digestible energy levels (DE) on kutum, Rutilus frisii kutum. Four is nitrogenous (35% protein) diets with digestible energy levels of 2500, 2600, 2700 and 2800kcal kg-1 was tested. Two hundred and forty advanced fry (2±0.4g) were randomly distributed in 12 fiberglass tanks of 400L capacity. Nutritional responses in terms of WG, FCR and PER as well as survival rate (SR) significantly improved (p<0.05) with increase in DE level from 2500 to 2800 kcal kg-1 diet, but no difference between 2600 and 2700kcal kg-1 diet was found. Body crude protein and fat significant were increased (p<0.05) when the dietary energy was raised up from 2500 to 2600kcal DE kg-1 diet, but a further increase on energy did not improve the fish crude protein and fat content.
