The Effect of Phytase Addition in Promoting Partial Replacement of Soybean Meal with Sesame Seed Meal on the Hematological and Biochemical Criteria of Common Carp Fish Cyprinus carpio L

The goal of this study is to study the effects of substitution of soybean meal by sesame seed meal in the diet of common carp, Cyprinus carpio L. Fish were fed seven experimental diets that included soybean meal substituted with sesame seed at 25, 35 and 45 percent, respectively, in the second, fourth and sixth diets and phytase (1200 IU\ Kg) added with the same replacement in the third, fifth and seventh diets, as well as the control diet (first diet). The data analysis of the edible portion of the body demonstrated a significant superiority (P ≤ 0.05) in the dry matter and crude protein criterion for fish fed the phytase-containing ration over the control ration. The high ether extract and proportion of phosphorus deposited in the bodies of fish fed the fourth and seventh diets, but the percentage of ash did not differ significantly from the control diet. Fish fed the third diet had a significant increase in PCV, Hb and TP, whereas fish fed the seven diets had such a significant increase in the value of globulin when compared to the other experimental diets. When fish were fed the seventh diet compared to the control diet, albumin levels were significantly higher, while glucose levels were lower significantly in control compared with the rest of the experimental rations. However, there was no significant difference in cholesterol levels between the different experimental treatments. As fish were given the seventh diet, the percentage of triglycerides increased significantly and the ALT and AST criteria decreased significantly when compared to the control diet.
