Effects of Adding Garlic, Thyme And Sage Powder and Oil to Juvenil Trout Feed

Abstract

In this study, powder (5%) and oil (1%) forms of medicinal and aromatic plants sage (Sage officinalis), thyme (Origanum onites) and garlic (Allium sativum) were added to the feed of juvenile rainbow trout (Oncorhynchus mykiss W.) to improve growth performance and performance. In this study, powder and oil forms of garlic, thyme and sage were tested and their antioxidant enzyme activity and growth values were determined. For this purpose, 5% (0.05 mg/kg) of the powder forms of sage, thyme and garlic and 1% (0.01 mg/kg) of the oil forms of the same products were added to the trial feeds. Fish weigh an average of 17 grams. It was tested in spring water with its physicochemical properties for 80 days (water temperature; 8ºC, dissolved oxygen 9.6 ppm. pH: 6.5). In the study; Live weight gain (41.32±2.47), specific growth rate (3.72±0.47), and feed conversion rate (1.04±0.097) were best obtained in the SY group (p<0.05). Among the antioxidant enzyme activities, malondialdehyde (MDA) was insignificant between the groups (p>0.05), while catalase activity was best in the thyme group, and superoxide dismutase (SOD) was best in the garlic groups (p<0.05).
