摘要：The effects of dietary garlic (Allium sativum) powder as a feed additive on hematological and biochemical health characteristics of European Sea bass Dicentrarchus labrax juveniles were studied. Experimental fish were fed diets supplemented with garlic powder at 0 (control), 2%, 4%, or 6% levels for a period of 60 days. Results showed that the red blood cell count (RBC), hemoglobin (Hb) concentration, hematocrit (%), and mean corpuscular Hb in fish fed garlic powder diets at dietary inclusion levels of 4% and 6%, were significantly lower than the control values. Serum glucose was significantly lower in Sea bass that were fed garlic powder diets (4% and 6%) compared to the control group. Serum triglyceride and globulin levels in fish fed a 4% garlic powder diet were significantly higher than the control values, whereas these two variables in the 2% and 6% garlic treatments were similar to the control values. The cholesterol levels in the 2% and 6% treatment groups were lower than the value recorded for the control group. As a result, it is suggested that garlic powder supplementation in diets for Sea bass juveniles should not exceed 2%. The present study is the first attempt to examine the effects of dietary garlic powder on the hematological and biochemical status in Sea bass juveniles.
