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, worn 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.
研究了两种不同来源的膳食锰对雏鸡（未感染和感染鸡蛔虫）的影响。雏鸡日粮中以硫酸锰（MnSO4·H2O）或二甘氨酸氯化锰（2Gly.MnCl2·2H2O）的形式添加0.9 g Mn2+ /kg食物，持续20天。雏鸡分为六组：第0组为对照组；第1组为对照组 + 硫酸锰；第2组为对照组 + 二甘氨酸氯化锰；第3组为感染鸡蛔虫组；第4组为感染鸡蛔虫 + 硫酸锰组；第5组为感染鸡蛔虫 + 二甘氨酸氯化锰组。对体重、死亡率、虫体负担和肝脏锰含量进行了研究。过量的膳食锰增加了体重和锰水平，但死亡率和虫体负担未受影响。确定了二甘氨酸氯化锰中锰的生物利用度更高。
