The Effect of Cell Wall Content of Wheat and Rice Brans on Biological Relative Bioavailability Value of Minerals Binding from the Broilers Diet

Abstract

An experiment was conducted to study the effect of dietary fiber (DF) consist of NSP and lignin content of wheat bran and rice bran the relative biological availability of minerals supplementation in the broilers diet. A total of 120 broiler chicks (Ross 308) arranged with 4 repetitions (6 birds per each replicated) on the 5 treatments diet in metabolic cages. The experimental diets contain one control diet and 4 diets were formulated, basal diet containing 25% wheat bran and rice bran that those supplemented with multi-enzyme. Data shown that enzyme supplementation had effect on increase biological apparent Ileal digestibility values minerals of diets content wheat bran and rice bran were relatively high P digestibility. Thus, those cell wall were effected on bon quality characteristics and seedor index tibiae respectively (P<0.05). The present study shown that relative bioavailability values (biological availability), of minerals concentrations of wheat bran and rice bran as cell wall consist of nonstarch polysaccharide and lignin source sources based on slope of regression response to control diet was set equal to 100%, on them on daily dietary minerals intake were estimated. Relative bioavailability values, based on daily dietary minerals intake, when response to control diet was set at 100%, were 30.78, 71.43, 0.64, 91.67, 96.15 and 138.46 for rice bran, as well; values of wheat bran are 50.00, 28.57, 1.82, 42.50, 46.15, and 30.77, respectively. The result of experiment indicated that Zn, Fe, Mn and P from rice bran, as well as, Ca, Mn, and Fe for wheat bran were have highly relative bioavailability values, with respect to amount of cell wall consist of non-starch polysaccharide and lignin sources.
