Masere ve Soğuk Pres Susam (Sesamum indicum L.) Yağının, Yüksek Yoğunlukta Stoklanmış Gökkuşağı Alabalıkları (Oncorhynchus mykiss, Walbaum, 1792)’nın Antioksidan Enzim Aktiviteleri, Hematolojik Parametreleri, Nitro Blue Tetrazolium (NBT) Aktivitesi ve Et Verimi Üzerine Etkileri

Abstract

The study was aimed to determine the effects of macerated sesame oil (MSO) and cold pressed sesame (Sesamum indicum L.) oil (CPSO) on antioxidant enzyme activities, hematological parameters, nitro blue tetrazolium (NBT) activity and proximate composition of rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) at high stocking density. Fish (55.89±2.05 g) were fed diets supplemented with same concentration (%2) of MSO and CPSO for 21 days. It was determined that the values of mean corpuscular hemoglobin (MCH), platelet (PLT) values of the CPSO and group and the corpuscular hemoglobin concentration (MCHC), platelet (PLT), mean platelet volume (MPV), platelet-large cell ratio (PLCR), granulocyte (GRAN), nitro blue tetrazolium (NBT) levels of the MSO group were increased. It was found that glutathione peroxidase (GPx) and catalase (CAT) activities of CPSO groups were rised. The results were statistically significant at P< 0.05 level. In the study, the dry matter ratio increased in each experimental group compared to the control group, the moisture, ash and protein ratio did not change, the fat ratio decreased compared to the control group. Both macerated sesame oil and cold pressed sesame oil could be recommended to alternative food additives.
