Olive pomace and soybean-sunflower acid oils as alternative fat sources in "European Seabass" (Dicentrarchus labrax) diets: effects on performance, digestibility and flesh fatty acid composition and quality parameters.

Eight diets were fed for 100 days (101.37 0.33 g initial weight, mean SD), differing in the added fat source (25% fish oil, 75% experimental oil): S (crude soybean oil), SA (soybean-sunflower acid oil), O (crude olive pomace oil) or OA (olive pomace acid oil); 3 blends: S-O, S-OA, SA-OA at a 1:1 ratio; and a diet containing only fish oil (F) as a control. Animals fed OA showed the worst performance among dietary treatments, with the lowest weight, specific growth ratio, average daily gain and the highest feed conversion ratio (p < 0.01). In contrast, other diets including acid oils did not impair performance. Acid oil diets did not affect the apparent digestibility of dry matter, crude protein or total fatty acids (p > 0.05), but a lower digestibility of lipids and saturated fatty acids was observed (p < 0.001). Flesh composition and fatty acid profile were not affected by the high dietary free FA content (p > 0.05). Hence the results suggest that the studied acid oils may potentially be used in fish diets although further studies are needed.application/pdfenopen accessLubinas - Alimentación.Ácidos grasos.Fatty acids.Oils and fats, edible - Quality control.Peces - Alimentación.European seabass - Feeding and feeds.Aceites y grasas comestibles - Control de calidad.Fishes - Feeding and feeds.Piscicultura.Fish culture.Artículohttps://doi.org/10.3390/ani12091198https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
