Effect of Dietary Energy to Protein Ratios on Growth Performance and Feed Efficiency of Juvenile Grass Carp (Ctenopharyngodon idella)
A feeding trial of three dietary protein (DP) (25, 35 and 45%) and four dietary lipid (DL) levels (3, 6, 9 and 12%) with different dietary energy to protein (E/P) ratios (from 5.93 to 13.84 kcal/g protein) was conducted to investigate the proper dietary E/P ratio for juvenile grass carp. After acclimation of 2 weeks by a lipid-free diet, fish were reared for 10 weeks in a water recirculation sy...
متن کاملEffect of saffron petal powder on feed, growth performance and antioxidant enzymes activity of grass carp (Ctenopharyngodon idella)
The present study was conducted to determine the effect of saffron petal powder on the growth and activity of antioxidant enzymes in the grass carp larva (Ctenopharyngodon idella). Fish larva (0.75 ± 0.03 g and 4.39± 0.09 cm) were fed separately with four levels of saffron petal powder diets which were included; P0 (0%), P1 (2%), P2 (4%) and P3 (6%) for 60 days. One thousand two hundred fish we...
متن کاملEffects of Feeding Frequency on Growth Performance and Survival Rate of Grass Carp (Ctenopharyngodon idella)
In present study the effect of feeding frequency on growth performance, feed efficiency and survival rate of juvenile of grass carp were investigated. Three groups of juvenile grass carp (average weight 4.31±0.1 g) designed with three feeding frequencies one meal a day (D1), two meals a day (D2) and four meals a day (D3) with two replicates of each treatment combination were applied in this exp...
متن کاملGrowth Response of Juvenile Grass Carp (ctenopharyngodon Idella) Fed Isocaloric Diets with Variable Protein Levels
Sixty days feeding experiment was conducted on grass carp fry fed isocaloric diets with variable protein levels in order to evaluate its growth response. Different diet ingredients were analyzed for % age protein, % age fat, % age ash, % fiber, % age moisture contents and energy. Five isoenergetic (17.91 ± 0.02 Kg MJ ) and isolipidic (8.56 ± 0.09 g) diets with varying protein levels PL1 (20%), ...
متن کاملEvaluation of the toxic effect of peracetic acid on grass carp (Ctenopharyngodon idella) juveniles.
OBJECTIVES The aim of present study was to evaluate the effect of peracetic acid (PAA) on haematotological and biochemical indices, antioxidant status, micronucleus induction and histopathological alterations of liver and gill in grass carp. METHODS Grass carp (Ctenopharyngodon idella) juveniles were exposed to therapeutic concentrations (1, and 3 mg x l(-1)) of PAA for a period of 10 days. S...
