Pengaruh L-Karnitin terhadap Kadar Lemak Daging dan Komposisi Tubuh Ikan Patin (Pangasius hypopthalmus)
Abstract: This study was
conducted to investigate the effect of dietary L-carnitine level on muscular
lipid and body composition of asian catfish (Pangasius hypopthalmus). Four
isoprotein and isocaloric diets with different levels of L-carnitine, 0.00%
(diet K), 0.10% (diet A), 0.18% (diet B), and 0.29% (diet C) were applied in
this experiment. Ten fishes with initial body weight of 35.86 ± 1.54 g were
cultivated in each aquarium (water volume 60 l) for 50 days. Fishes were fed
three times daily at satiation. The results showed that L-carnitine in the
liver increased by increasing dietary L-carnitine level. While increasing
dietary L-carnitine until 0.18% decreased content of lipid in the liver, but
excessive dose of dietary L-carnitine increased content of lipid in the liver.
It was further observed that L-carnitine in the diets reduced the muscular lipid
content from 32.35 to 7.51% dry weight, but had no effect on body composition.
