Ability of European seabass (Dicentrarchus labrax) to digest rendered animal fats from fish, poultry and mammals

This study evaluates the in vivo apparent digestibility coefficients (ADC) of rendered animal by-product fats in European seabass (Dicentrarchus labrax) juveniles. Diets contained fish oil (FOd), poultry fat (PFd) or mammal fat (MFd), from rendering animal by-products, at 140 g/kg. Macronutrient and fatty acids ADCs were evaluated in quadruplicate tanks with fifteen 100 g fish. While total lipids ADCs (88%–90%) were unaffected, individual fatty...
