Effect of l-carnitine usage on hepatic, visceral lipogenesis and growth performance of gilthead sea bream (Sparus aurata Linneaus, 1758) in net cage

Abstract

In this study, effects of dietary L-carnitine supplementation on hepatic, vısceral lipogenesis and growth performance of gilthead sea bream was investigated. Study was carried out 120 days. In this experimentation 3 groups (one of it is control) with 2 parallel was created and 6 net cages in 5x5x5m dimension was used. 5000 fishes with 198±1,5 g initial weight was put into each cages. Control group fishes was fed with normal commercial feeds. Other 2 experimentation group fishes was fed with feeds with L-carnitine supplemented respectively, 0,8 and 1,6 lt/100 kg feed. At the end of the experiment weight changes was examined and maximum final weight was determined in group G2 with 263,27±1,8 g. When weight gain examined, maximum weigth gain was determined in group G2 with 64,92±1,8 g. There was no differences between total weight of groups (p>0,05). Mortality was determined in group G0 with 416. Mimimum mortality was determined in group G2 with 372. There was variations on FCR values between groups (p<0,05). Minimum FCR was determined in group G2 with 1,79±0,05. Minimum HSI and VSI were determined in group G2 respectively, 2,5±0,29 and 8,3±0,4. This study showed that dietary L-carnitine supplementation enhances growth performance and decreases mortality. HSI and VSI was determined minimum values in group G2. It supports that dietary L-carnitine supplementation helps decreasing of hepatic and visceral lipogenesis. This idea was supported with liver examination.

Bu çalışmada, yeme L-karnitin ilave edilmesinin çipura balığının karaciğer, iç organ yağlanmaları ve gelişimi üzerine etkileri incelenmiştir. Çalışma 120 gün (Ekim 2007-Ocak 2008) sürdürülmüştür. Bir kontrol grubu kontrol olmak üzere 2 paralelli 3 grup oluşturulmuş ve 5x5x5m boyutlarına sahip 6 adet ağ kafes kullanılmıştır. Her bir kafese canlı ağırlığı ortalama 198±1,5 gr. olan 5000 adet çipura yerleştirilmiştir. Kontrol grubu (G0) balıklara karnitin içermeyn normal ticari yem verilirken, deneme grupları (G1 ve G2) balıklarına sırasıyla, 0,8 ve 1,6 L/100 kg oranında L-karnitin ilave edilmiş yem verilmiştir. Çalışma sonucunda ağırlık değişimleri incelendiğinde en yüksek canlı ağırlığın 263,27± 1,8 ile 64,92±1,8 canlı ağırlık artışı ile (G2) grubunda elde edildiği tespit edilmiştir. Total boy verileri incelendiğinde ise gruplar arasında önemli bir fark bulunamamıştır (p>0,05). Balıklarda oluşan mortalite incelendiğinde en yüksek mortalitenin 416 adet ile kontrol grubunda (G0), en düşük mortalitenin ise 372 ile (G2) deneme grubunda olduğu tespit edilmiştir. FCR değerlerinde gruplar arası farklılıklar oluşmuştur (p
