Effects of dietary L-carnitine supplementation on growth, muscle fatty acid composition and economic profit of rainbow trout (Oncorhynchus mykiss)

Öz:

Bu çalışmada, L-carnitine’nin gökkuşağı alabalığının (Oncorhynchus mykiss) büyümesine ve kas yağ asidi kompozisyonuna etkisi incelenmiştir. Balıklar; hiç L-carnitine eklenmeyen kontrol grubu yemleri ve 300 mg $kg^ {-1}$ L-carnitine (LC300) ve 600 mg $kg^ {-1}$ L-carnitine (LC600) içeren yemlerle 63 gün boyunca beslenmişlerdir. LC600 grubu kontrol grubundan %7,73 daha fazla canlı ağırlık kazanmıştır. Yem değerlendirme oranı açısından LC600 (1,66) ve LC300 (1,60) gruplarının kontrol grubundan (2,00) daha iyi olduğu bulunmuştur. L-carnitine eklenen grupların kontrol grubuna oranla daha düşük üretim maliyeti sağladığı bulunmuştur. LC300 grubunun (2,71 US.$ $kg^ {-1}$) ekonomik dönüşüm oranı (EDO) kontrol grubuna göre 0,44 US.$ $kg^ {-1}$’lık tasarruf sağlamıştır. L-carnitine eklemenin protein oranı dışında, kaslardaki genel besin içeriğinde bir değişiklik yapmadığı saptanmıştır. L-carnitine eklenen grupların protein içerikleri kontrol grubundan daha yüksek çıkmıştır. Alabalıklarda L-carnitine eklenmesi kaslardaki total doymuş, tekli doymamış ve çoklu doymamış yağ asidi içeriklerini yükseltmiştir. Elde edilen sonuçlar, ticari kafes şartlarında, diyete 600 mg L-carnitine/kg eklenmesinin, 300 mg Lcarnitine/ kg eklenmesinden ve hiç eklenmemesinden daha etkili büyüme sağladığını göstermektedir.

Öz:

In this study, the effect of dietary L-carnitine on growth, proximate and muscle fatty acid compositions of rainbow trout (Oncorhynchus mykiss) were investigated. The fish were fed with diets containing 300 mg $kg^ {-1}$ L-carnitine (LC300), other group was fed with diets containing 600 mg $kg^ {-1}$ L-carnitine (LC600) and control group was not supplementary L-carnitine for 63 days. The weight gain of LC600 fed with L-carnitine supplemented was found to be 7.73% higher than in control group. Feed conversion ratio in LC600 (1.66) and LC300 (1.60) is better than in control group (2.00). L-carnitine supplemented groups would be lower cost of production than control. Economic conversion ratio (ECR) of LC300 (2.71 US.$ $kg^ {-1}$) would represent a saving of 0.44 US.$ $kg^ {-1}$ compared to the control. L-carnitine administration did not affect proximate composition of muscle except for protein percent. Protein content of L-carnitine supplemented groups was higher than control group. Total saturated monounsaturated and polyunsaturated muscle fatty acid content increased by L-carnitine supplementation in rainbow trout. The results indicate that supplementation of 600 mg L-carnitine/kg diet is more effective on growth than the other L-carnitine supplementation level 300 mg $kg^ {-1}$ and control diet in commercial cage conditions.
