This study was conducted to detect the effect of using Aspergillus oryzae on the diets of common carp (Cyprinus carpio L.), in Growth performance and blood traits. 320 common carp fish were randomly distributed with an average weight of 90.5 (±25) g fish-1, in to sixteen plastic ponds with dimensions of 100 ˟ 100 ˟100 cm, for each tank capacity 1000 of liters.
On eight experimental treatments and at a rate of two replicates for each one treatment and 20 fish for each replicate. Eight rations were made manually with a diameter of 4mm, the experimental fish were fed with 3% of the body weight the protein content ranged between 37.7-37.29 % and it was left without addition, while the treatment (T1) first treatment as comparison treatment. (T2) was added at ratio of 50% fermented soybean meal, (T3) was added at ratio of fermented soybean meal 100% , as (T4) the fourth treatment bran was added at ratio 50% fermented bran, (T5) 100% fermented bran, (T6) in the sixth treatment yellow corn powder was added at ratio of 50% fermented, (T7) corn powder added at ratio 100% fermented, (T8) while in the eighth treatment add both 100% fermented soybean meal, 100% fermented corn powder, and100% fermented wheat bran, at the end of the experiment, blood samples were taken for the experimental fish. The results of the statistical analysis showed that T8, T7, T3, T1 were significantly( p≤0.05) superior to the number of the red blood cells, whose values reached (3.75, 3.33, 3.31, 3.28) (109 cell L-1) over the rest of the treatments, and T8 significantly ( p≤0.05) for HD hemoglobin, which was 11.9 gmdl-1, was superior the rest of the treatments, and in pcv, T8 fish compared with the rest of the treatments if the highest value was recorded at 38.0%, while no the results showed that there were significant differences at the level ( p≤0.05) between the experimental treatments. |
