Abstract
This investigation was carried out for 84 days in 18 glass aquarium (40cm×30cm×70cm/70 L). A total common carp Cyprinus carpio L. (144) with an average weight of 12.24±1.04 gm/fish were assigned randomly into nine groups of two replicates for each group, each replicate included 8 fish. The fish were fed on nine diets experimental that were identical in isonitroenons (30.51%-3182%) and isocaloric (1456.7-1478.3 MJ/kg). Sunflower oil (SO) were added at levels of 0, 0.5%, 1%, 1.5% and 2% in the first five diets and corn oil (CO) at the same levels in diets 6-9 as different source and levels of ω-6 fatty acids. The results of statistical analysis for weight gain (WG), daily weight gain (DWG) and relative growth ratio (RGR) were insignificantly varied (p<0.05) among T4, T5 and T8 which increased significantly (p>0.05) as compared with T1, T2, and T3. The T4 (1.5% SO) and T8 (1.5% CO) REVEALED the best results which were 14.79 and 15.95 gm/fish for WG and 0.179 and 0.189 for DWG and 122.13% and 128.21% for RGR respectively. The parameter of SGR increased significantly (p>0.05) T 8(0.098, supreme value) compared with other treatments except T 4. The parameter of FCR and FER were significantly higher for T8 which were 3.04 and 32.84% respectively. The of PER showed no insignificant different (p<0.05) among T 1, 2, 3, 5, 6,7 and 8, the T5 (2% SO) and T8 (1.5% CO) supreme values which transcribed 0.944 and 1.03 for PER respectively. The above results showed preference of the T4 and T8 (1.5% SO and 1.5%CO respectively) that achieved the best value for WG, RGR, FCR, SGR and PER. Therefore, It is we recommend to use the 1.5% sun flower or corn oils in the diets of carp fingerling.
