The objective was to measure the levels of minerals in the liver and blood of sheep, fed with high levels of poultry manure. Two experimental groups were considered: a treated group (ovine bellies that consumed poultry manure for at least three years) and a control group (lambs in fattening that did not consume poultry manure). Six animals (n=6) from each group were randomly sacrificed, blood samples were collected prior to slaughter, and hepatic tissue samples were subsequently taken. The minerals analyzed were copper (Cu), iron (Fe) and zinc (Zn). In the treated group, concentrations of Cu, Fe and Zn were 176.23, 9.58, and 72.63 mg/L, respectively. While in the treated group they were 85.35, 13.41 and 112.0 mg/L, respectively. The Cu determinations of the treated group were higher in both liver and blood (p <0.05). However, in spite of the time of exposure to poultry manure consumption, the animals showed no signs of copper intoxication, which could be conditioned by the low concentration of the mineral in the poultry excreta.
