Trace minerals are important for broiler growth and are used in various physiological, digestive and biosynthetic process of the body. Trace minerals act as cofactors in many enzymes and are associated with proteins involved in intermediary metabolism, hormone secretion path ways and the immune system (Dieck et al., 2003). In broilers, organic trace minerals are better absorbed and utilized and have a greater bioavailability than inorganic trace minerals (Bao et al., 2007). This experiment was conducted to examine the effect of trace mineral sources on broiler performance and carcass composition.
