Abstract

This study was conducted in fish diseases lab. / College of veterinary medicine/ university of Sulaimani to evaluate the effect of boiling oak as compared with raw oak on the performance of common carp at 0.05 significant level for all studied parameters. This study was carried out on C. carpio L. for five treatments/ three replicates. The experimental trial consists of five treatments with three duplicates, each containing seven fish: Group 1: Diet without any supplement as a control group, Group 2: adding 10g raw oak/ kg diet, Group 3: adding 20g raw oak/kg diet, Group 4: adding 10g boiled oak/kg diet, Group 5: 20 grams of boiling oak/kg diet. The second group with 10g raw oak/ kg diet and T5 with 20g boiled oak/ kg diet was high significantly in the final weight, weight gain, significant and relative growth rate. T3 with 20g raw oak/ kg diet was higher significantly in FCR, T4 with 10g boiled oak/kg diet was higher significantly in FER. RBC *1012/L was higher in T4 with 10g boiled oak/ kg diet and T5 with 20g boiled oak/ kg diet were higher significantly, in HGB g/L the T2 with 10g raw oak/ kg diet and T3 with 20g raw oak/kg diet were higher significantly. T3 with 20g raw oak/kg diet was significant in each of the indices MCH pg and MCHC g/L. T4 with 10g boiled oak/kg diet was higher significantly in each of HCT %. The control was significantly higher in PLT *109/L. T5 with 20g boiled oak/ kg diet was significantly high in Sugar and HDL. Total Protein was significantly high in control and T2 with a 10g raw oak/ kg diet. Cholesterol was significantly high in T2, T4, and T5 as compared to the control group. GOT and CKI was significant in T3. A Hepatosomatic index was higher significantly in each of T2, T3 and T5. Gill somatic Index was significant in all treatments as compared to T3. Gonadosomatic Index was significant in all treatments as compared to T2 and T4, in the Intestine Weight Index and Intestine Length Index, all treatments were significantly different from the control. In the Intestine Length (Fish Length) Index, T2 was substantially greater. The current study’s findings imply that oak acorn powder is a viable feed additive, indicating a starting point for additional research into its potential use as an antioxidant and immune booster in various fish species.
