چکیده مقاله:
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

The study was conducted with a completely randomized design consisting of four treatments in triplicates. Experimental diets were formulated to contain four different lipid levels (8, 10, 12 and 14%) at constant protein level (46.8%) and different gross energy of 4314, 4417, 4519 and 4622kcal/kg, respectively. Kutum fry (average weight, 203±4mg) were randomly assigned and distributed at a densi...

A feeding trial has been conducted to evaluate the effects of dietary nucleotide (NT) on growth performance and stress resistance of fry kutum (Rutilus kutum Kamenskii, 1901). A basal diet supplemented with 0 (control), 0.3, 0.5 and 0.7 g NT kg-1 have been formulated for four experimental diets. After 8 weeks of feeding trial, growth parameters were evaluated and then fish has exposed to osmoti...
