parenteral route, in buffalo calves raised on the Marajó Island (PA). Fourteen animals were divided into
two groups. Group 1 received three doses of 120 mg of copper glycinate (20mgCu/mL), intramuscularly,
on days 1, 45 and 90; in the group 2 (control) the animals were Not supplemented with copper. In both
groups liver biopsies were performed on days 1 and 135. The diagnosis of copper deficiency was
established through history, clinical signs, and by the analysis of hepatic copper content. In group 1, the
mean hepatic copper content increased from 17.4±5.84mg/kgDM (before administration) to
311.2±133.5mg/kgDM (after 135 days) (P<0.05). In the control group, the mean of hepatic copper
contents decreased from 17.1±3.4 to 9.11±1.1mg/kgDM at the end of the experiment (P<0.05). Based on
the results, it was demonstrated that the administration of copper, by parenteral route, was efficient in the
treatment of copper deficiency in buffalo calves and could become a very promising option for the reality
of buffalo producers on the Island of Marajó
