Crude fat, digestible protein and DL-carnitine levels in plant-based diets to Nile tilapia Oreochromis niloticus fingerlings

ABSTRACT The chemical composition of diets is appointed as one responsible by different results of L-carnitine supplementation in fish. This study determined the effects of digestible dietary protein (DP; 250 and 290 g kg-1) and crude fat (CF; 100 and 150 g kg-1) at levels of DL-carnitine supplement...
