Abstract

The effect of dietary manganese from two different sources on chicks (uninfected and infected with Ascaridia galli) was studied. Chick diet was supplemented with 0.9 g Mn2+ kg-1 food either in the form of MnSO4.H2O or 2Gly. MnCl2.2H2O for 20 days. Chicks were divided into six groups: group 0, control; group 1, control + MnSO4.H2O; group 2, control + 2Gly.MnCl2.2H2O; group 3, infected with A. galli; group 4, infected with A. galli + MnSO4.H2O; and group 5, infected with A. galli + 2Gly.MnCl2.2H2O. Body weight, mortality, worm burden, and liver manganese content were investigated. Excess dietary manganese increased weights and manganese level, but mortality and worm burden were unaffected. A greater bioavailability of manganese from 2Gly. MnCl2.2H2O was established.
