Five experimental diets were obtained by supplementing a basal diet with 6% of P (P6), 6% of SA (SA6), 4% of P + 2% SA (P4- SA2), 2% of P + 4% of SA (P2-SA4) and 6% of S (S6). A total of 480 one-d-old female broiler chickens (Ross 308) were housed in metabolic cages (6 cages/treatment, with 16 birds/cage). Replacing P with SA improved fat absorption at 11 and 35 d (p < 0.05), but not feed AME values and saturated FA (SFA) digestibility at 11 d. As age increased, the absorption of SFA and free fatty acids (FFA) improved, and the contribution of the upper ileum to FA absorption increased (p < 0.05). At 35 d, SA6 (56% FFA) and P2-SA4 (40% FFA, 2.6 unsaturated-to-saturated FA ratio) could replace S6 without impairing fat utilization. The replacement of P with SA represents a suitable strategy to use this by-product.application/pdfenopen accessPollos - Alimentación.Chickens - Feeding and feeds.Aves de corral - Alimentación.Poultry - Feeding and feeds.Ácidos grasos.Fatty acids.Chickens - Breeding.Lipids in nutrition.Alimentos para animales.Animal feeds.Pollos - Aparato digestivo.Chickens - Digestive organs.Pollos - Cría y explotación.Aceites y grasas en nutrición.Replacement of palm oil with soybean acid oil in broiler chicken diet : fat digestibility and lipid class content along the intestinal tractArtículohttps://doi.org/10.3390/ani11041035https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
