Nutrient digestibility in broiler chickens fed diets containing high levels of soybean oil is affected by the source of fiber

This study evaluated the effects of including soluble and insoluble dietary fiber sources in soybean oil-containing diet for broiler chickens on coefficient apparent ileal digestibility (AID) amino acids, retention (AR) nutrients, nitrogen-corrected metabolizable energy (AMEn). A total 180 broilers were divided into 30 groups fed 3 diets from day 14 to 21 age. The corn–soybean meal containing 6.8% oil without or with hulls (SBH) sugar beet pulp (SBP) at 8.0% as fiber, respectively. SBH SBP contained 6.0% 14.7% 60.5% 37.0% AID indispensable acids was decreased ( P < 0.05) due inclusion SBH, but not SBP. Dietary reduced AR gross (by 14% 8%, respectively) AMEn 20% 14%, respectively). Overall, a meal-based that contains high level might improve nutrient digestibility. However, has less detrimental than SBH.
