Conteúdo: | An experiment was conducted to investigate tissue trace mineral accumulation and depletion in sheep fed high dietary Mn in the form of reagent grade MnO. During the pre-trial phase, 32 wethers, 56 kg initially, were group-fed the basal corn-soybean meal diet (36 mg/kg Mn) for 8 days at which time eight sheep were slaughtered and tissues were taken to represent controls. For the remaining sheep, the experiment was divided into two phases of 6 wk and 12 wk; during the first phase (accumulation), the diet contained 8000 mg/kg supplemental Mn and during the second phase (depletion) the diet was the unsupplemented basal. Sheep were slaughtered at various intervals during both phases and tissue samples were taken. Manganese increased in all tissues measured during accumulation but decreased rapidly during the depletion phase. In general, liver and kidney Zn and Cu increased during the accumulation phase but tissue Fe decreased during this phase. MnO appeared to be a relatively safe supplemental source of Mn for sheep.
