Effects of Various Lipid Sources and L-Carnitine Supplementation on the Growth Performance, Body Composition, and Antioxidants Enzyme Ability of Dog Conch Larvae, Laevistrombus canarium

A feeding experiment was conducted to study the effects of dietary lipid sources and L-carnitine on growth performance, body component, muscle fatty acid composition, antioxidant enzyme ability average weight 0.28 g dog conch larvae, Laevistrombus canarium. Three lipid: fish oil, soybean beef tallow were tested in combination with two levels (0 0.5%) L-carnitine. The larvae fed diets containing oil supplementation exhibited highest gain. After air exposure challenge, liver tissue without supplemented had lower superoxide dismutase (SOD, U min−1), phenoloxidase (PO, glutathione peroxidase (GPx, mU/mL) activity. activity SOD, PO, GPx increased increasing In particular, diet significantly ( P < 0.05 ) enhanced responses. thiobarbituric reactive substances (TBARS) showed id="M2"> higher It concluded that administration can enhance resistance against beta-oxidation, best strategy promote due high nutritional availability.
