Yeme İlave Edilen Sumak (Rhus coriaria L.)’ ın Gökkuşağı Alabalıkları (Oncorhynchus mykiss)’ nın Spesifik Olmayan Bağışıklık Tepkisi, Hematoloji ve Vibrio anguillarum’ a Karşı Direnç Üzerine Etkisi

This study aimed to investigate the effects of sumac (Rhus coriaria L.) fruit powder in different concentrations as feed additives on non-specific immune response, hematology, and disease resistance rainbow trout (Oncorhynchus mykiss). Fish (35.67±0.88 g) were fed with experimental diets (1.0, 3.0, 5.0 10.0 g kg-1) at four concentration. There no significant differences between groups control group by mean red blood cell count (RBC), white (WBC), differential leukocytes (monocyte, lymphocyte, neutrophile), hematocrit (Hct), hemoglobin (Hb), (MCH pg), concentration (MCHC %), volume (MCV µm3) plasma lysozyme, Immunoglobulin M (IgM), total protein level 8 weeks. After weeks feeding, fish challenged Vibrio anguillarum cumulative mortality was recorded over 21 days. Dietary administration 1.0, kg−1 significantly increased survival rate (p<0.05). The diet received showed post V. anguillarum. These results that improved when added
