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.

Highlights

The source of a dietary fiber consists of non-starch polysaccharide and lignin, has become of concern due to differences in chemical structure and variation in binding capacity [1,2,3]

Summary

Introduction

The source of a dietary fiber consists of non-starch polysaccharide and lignin, has become of concern due to differences in chemical structure and variation in binding capacity [1,2,3]. The Investigations of mechanisms in mineral binding by dietary fiber consist of non-starch polysaccharide and lignin is believed to involve physical retention, or chemical binding of the minerals to the free hydroxyl groups of cellulose polymers. Dietary fiber consist of nonstarch polysaccharide and lignin defines as cell walls of plant tissues, that are resistant to digestion, absorption in gastrointestinal tract, and are heterogeneous in terms of nutritional, chemical and physical nature [5,6]. Such activity has been attributed to groups such as uronic acid in hemicelluloses and pectin, and phenolic groups in lignin, giving mineral binding properties to fibers [7]. Dephytinized of the barns’ insoluble fiber fraction bound Cu2+, Ca2+ and Zn2+ ions, and increased the
