Factors Affecting Manganese Homeostasis in the Chick

Plant and animal sources of manganese (Mn) are, for the most part, unavailable to the chick. Corn (C), soybean meal (SBM), fish meal (FM) and wheat bran (WB) reduced tissue Mn concentrations when added to a purified phytate- and fiber-free diet. Although these feed ingredients contain significant quantities of Mn, as little as 1.0% WB, 2.5% FM, and 5.0% of a C-SBM mixture markedly depressed Mn deposition in tissues. Moreover, the addition of these feed ingredients to the purified diet, containing the minimal requirement level of Mn (14 mg/kg as MnSO(,4)), depressed chick performance over the course of a 7-week feeding period. FM also increased the severity of perosis.
