Abstract
ABSTRACT The experiment was conducted for investigating the effect of Non-Starch Polysaccharide (NSP) feed containing wheat and barley on relative bioavailability values (RBVs) of minerals and supplementation in the broilers’ diet. A total of 72 male broiler chickens (Ross 308) were arranged with 4 repetitions (6 birds per each replicated in the metabolic cages) on the 3 treatment diets. The experimental diets contain one control diet and 2 diets with formulation of 25% wheat and 20% barley. Estimated relative mineral bioavailability values (RMBVs) were based on daily dietary mineral intake. The RBVs of Ca, P, Cu, Mn, Fe, and Zn were 44, 120, 17, 0.37, 125, and 15.38, respectively for dietary-containing wheat. Data showed that NSP contain a diet effect on bone characteristics and seed or index tibiae bone (P < 0.05). RMBVs of Ca, P, Mn, Fe, and Zn for a diet including wheat were 65.20, 84.96, 21.05, 8.50, and 2.56, respectively based on the tibia bone. Also, RMBVs of tibia bone minerals, such as Ca, P, Mn, Fe, and Zn from a diet containing barley, were 53.60, 43.33, 40.60, 44.16, and 44.69, respectively. The results of experiments indicated that Ca, P, and Fe have highly RMBVs concerning the amount of NSP contained in barley.
