Abstract

A feeding trial was performed to assess any beneficial effect of three herbal oils; mint, thyme and sage oils containing 74 g kg-1pulegone, 77 g kg-1 carvacrol and 76 g kg-1 1,8-cineole, respectively on growth performance, survival, fatty acid composition, and liver and kidney histology of rainbow trout (Oncorhynchus mykiss). Herbal oils were added at 0.5 %, 1.0% and 1.5 % concentrations to a fish mealbased control diet, and each diet was fed to triplicate groups of rainbow trout fingerlings for 60 days with growth parameters recorded weekly. Results showed that FCR was affected negatively in all mint oil diet fed groups where it was higher than that of control and other groups (P<0.05). The lowest FCR values were recorded in the thyme and sage oil containing diets fed groups (P<0.05) with no significant differences between these two groups. SGR was also found lower in mint oil groups than in control. The highest SGR was recorded in thyme and sage oil fed groups (P<0.05). Survival was similar in fish fed with diets containing thyme, sage oil and control diet (P>0.05). However, survival was the lowest in fish fed with mint oil supplemented diets (P<0.05). Whole body fatty acid profiles except total saturated fatty acids are closely influenced by dietary herbal oil administrations. Total polyunsaturated n-6 fatty acid was lowest in 1 %thyme oil and all sage oil diet fed groups (P<0.05). Total polyunsaturated n-3 fatty acid was similar between control and sage oil supplemented groups, but in other groups it was significantly decreased (P<0.05). EPA/DHA ratio was observed significantly low in 1.5 %thyme oil and all groups of sage oil fed fish. There were no histological differences observed in liver or kidney of fish fedwith control and 0.5 % and 1 % thyme and sage oil supplemented diets.The present results showed positive effects of thyme and sage herbal essential oil supplemented diets on growth performance and fatty acid utilization and these oils may be useful feed supplements in production of rainbow trout.

Özet

Sırasıyla 74 g kg-1 pulegon, 77 g kg-1 karvakrol ve 76 g kg-1 1,8-kinol içeren nane, kekik ve adaçayı gibi üç farklı bitkisel yağın alabalıkların (Oncorhynchus mykiss) büyüme performansı, yaşama, yağ asidi kompozisyonu ile karaciğer ve böbrek histolojisi üzerine etkilerini belirlemek amacı ile bu besleme çalışması yürütülmüştür. Bitkisel yağlar balık yemi içerisine % 0,5, % 1 ve % 1,5 oranında eklenmiş, ve her diyet büyüme parametreleri haftalık olarak kontrol edilen 60 günlük çalışmada üç tekerrürlü olarak alabalık yavrularına verilmiştir. FCR tüm nane gruplarında olumsuz etkilenirken diğer tüm gruplardan yüksek tespit edilmiştir (P 0,05). Bununla birlikte nane yağı ile beslenen gruplarda düşük tespit edilmiştir (P<0,05). Toplam doymuş yağ asidi hariç tüm yağ asitleri içeriği bitkisel yağ eklentisi ile değişiklik göstermiştir. Toplam çoklu doymamış n-6 yağ asitleri % 1 kekik ve tüm adaçayı içeren gruplarda en düşük değeri göstermiştir (P<0,05). Toplam çoklu doymamış n-3 yağ asitleri kontrol ve adaçayı yağı ekleniş gruplarda benzerken, diğer gruplarda önemli derecede düşmüştür (P<0,05). EPA/DHA oranı % 1,5 kekik yağı ve tüm adaçayı yağı içeren gruplarda kayda değer düşüktür. Kontrol, % 0,5 ve % 1 kekik ve adaçayı yağı içeren gruplarda karaciğer ya da böbrek histolojilerinde bir farklılık gözlenmemiştir. Bu çalışma sonuçları kekik ve adaçayı ile desteklenmiş yemlerin büyüme performansı ve yağ asidi kullanımı üzerindeki olumlu etki gösterdiğini ortaya koymuştur ve bu yağlar alabalık üretiminde yem katkısı olarak kullanışlı olabileceği belirlenmiştir
