The present study investigated the effects of dietary supplemented with sage leaf powder on growth performance, feed utilization, carcass composition, blood parameters and stress hormones in common carp Cyprinus carpio reared in cages in Grdarasha station, College of Agriculture Engineering Sciences, Salahaddin University- Erbil, Kurdistan Region -Iraq. A total of 54 common carp (25.5±0.5g fish─1) were randomly distributed into 9 cylindrical cages 0.2 m³ (Radius=25cm, Height=100cm). After two weeks of adaptation, eight weeks feeding trial was conducted from 17 September to 12 November 2022. There were four groups of fish fed control diet (T1) and fish fed diets supplemented with 0.5 (T2), 1 (T3), 1.5(T4) of sage powder. The results showed a significant increase in growth parameters and feed utilization with addition of sage powder. The level of LYM, MON, Hb, MCHC, RBC and Hct were significantly elevated by the addition of sage to experimental fish. In contrast, dietary supplementation of sage (T2, T3, T4) to common carp diet result in significant reduction in the level of WBC, GRA and MCV. The level of TG, total protein, ALP, albumin, lipase, HDL and globulin contents was increased using sage (Salvia officinalis) supplemented diet. However, level of AST, ALT cholesterol, LDL and glucose was significantly decreased with the addition of sage to the diets. The present results showed that dietary supplementation of sage led to a significant decrease in cortisol, T3, and T4 and significant increase acetylcholinesterase (AChE). In conclusion, sage can be used as feed additives enhanced growth, feed efficacy, blood indices and reduce stress.
