The redox potential of goat kid serum was evaluated, applying spectrophotometric assays intended for both clinical and research studies that can be automated on clinical auto-analysers, thus allowing rapid and inexpensive data collections. Although several correlations were shown, the results obtained with different assays can be strongly different depending on the method and technology of each assay. The present results can be useful to verify whether animals are experiencing oxidant status.

Since changes in metabolic requirements during pregnancy might produce a nutritional imbalance predisposing the mare to pathological conditions, we examined changes in serum macromineral profile and the statistical correlations between electrolytes in mares during the last 3 months of pregnancy and the first 3 weeks after foaling. The changes found in mares' macromineral profiles over the peripartum provide enhanced knowledge about mineral interrelations and their modifications in mares.
