Resumo
This study evaluated the effect of the parenteral administration of etilenodinitrile tetracetate of calcium
and copper on the weight gain, eritrograma and the hepatic and renal parenchymas in confined bovines,
using 200 animals, distributed in four groups (G) of 50 (I, II, III and IV). The groups I and II were
constituted by bovines with the age of 24 months and the groups III and IV by animals of 12 months,
which GI was given 100mg of active copper and GIII 75mg, both by subcutaneous way by the beginning
of the study. The other groups were used as the control. The weight measure of the animals of all groups
was done from 28 to 28 days during the 112 days of confinement. It was done the eritrograma in ten
bovines of each group and the dosage of the hepatic and renal concentration of copper and the
hystological evaluation, in the animals of the groups I and II. The values found on the eritrograma
showed normality and the hepatic and renal concentrations of copper in bovines with the age of 24
months showed depletion levels. It was not verified differences about the hystological evaluation between
the groups I and II. There was significant difference on the weight gain media between the groups I and
II. On the groups III and IV, it was not observed difference over the weight gain media.
