Özet:

A preliminary study was conducted to evaluate the effect of the Pelargonium sidoides extract on the haematological profile of common carp, Cyprinus carpio. The fish (mean body weight 0.67±0.05 g) were fed with experimental diets prepared by using the supplementation of P. sidoides extract (0, 1, 3 and 5 ml 100 g-1) for 90 days. The highest hemoglobin concentration was registered in 3 ml 100 g-1 P. sidoides extract-supplemented diet (10.50±0.45 g l-1) and 5 ml 100 g-1 P. sidoides extract-supplemented diet (11.02±0.20 g l-1). Among the P. sidoides extract-supplemented groups, the highest white blood cell values were also found in 5 ml 100 g-1 P. sidoides extract-supplemented diet (28.98±1.62 G l-1). The highest values of mean corpuscular hemoglobin concentration (P < 0.05) were detected in 5 ml 100 g-1 P. sidoides extract-supplemented diet. Red blood cell, hematocrit, mean corpuscular volume and mean corpuscular hemoglobin levels were not affected by any of the experimental diets (P>0.05). The results of the present work have demonstrated that P. sidoides extract-based diet affect basic haematological profile of common carp.
