Effects of The Cinnamon Oil (Cinnamomum verum) on Growth Performance and Blood Parameters of Rainbow Trout (Oncorhynchus mykiss)

Abstract

In this study, the effects of supplementation of cinnamon oil on rainbow trout (Oncorhynchus mykiss) feeds on fish growth performance, feed evaluation and blood parameters were investigated. In this scope, experimental diets containing cinnamon oil at 5 different concentrations of 0 mL/kg (TY0), 1 mL/kg (TY1), 2 mL/kg (TY2), 4 mL/kg (TY4) and 10 mL/kg (TY10) were prepared. During the 60 days of the study, the rainbow trout weights of 10,68±0,35 g were used and the experiment was carried out in 100 L volume aquariums with 5 groups of 3 replicate. In the feeding experiment, growth performance and feed utilization of the groups fed with cinnamon oil increased significantly compared to the control group. It was determined that cinnamon oil had significantly increasing effect on erythrocyte, hemoglobin amount and hematocrit ratio in fish. In addition, cinnamon oil decreased the level of serum glucose, triglyceride and cholesterol in the fish, and increased the total protein and albumin content. As a result, feed containing 4 mL/kg of cinnamon oil was affected fish growth performance and blood parameters positively.
