Abstract
Cultured male tilapia was fed diets supplemented with various levels of L-camitine
for 252 days and its growth and reproductive performance were evaluated. Carnitine
administration produced growth enhancement, increasing with dosage. Carnitine
stimulated feed conversion efficiency, better digestibility and high enzyme activity. The
RNA-DNA and protein contents in the muscle and liver also increased concomitant with
high growth rate. Carnitine induced lipid catabolism leading to reduction in lipid content
of cultured fish, using lipid as energy source while sparing protein for anabolic processes.
Significantly high GSI, sperm cell concentration, motility and percentage viability of the
spermatozoa in carnitine treated tilapia were observed.
