“…In a study of 32 healthy one day old, mixed-sex Black Neck ostrich chicks fed a diet supplemented with 0-600 mg/kg feed of L-carnitine for 60 days, a suppressive effect of growth response was observed for the highest L-carnitine concentration. The birds which were fed the highest dose of L-carnitine had the lowest live weight and weight gain as well as the highest feed conversion ratio (kg feed/kg weight gain) after the end of the study period indicating a suppressive effect of the supplement (Hajibabaei and Casey, 2012).…”
