ABSTRACT The aim of this study was to evaluate a new source of injectable organic zinc (zinc edetate) on the energy and oxidative profile in sheep during the immediate postpartum period. Twenty-six Texel breed animals were previously identified and divided into two experimental groups: the treated group (TG; n= 13) that comprised the animals that received a subcutaneous (SC) injection of 100 mg of zinc edetate (2 mL) fifteen days before the parturition expected date and the control group (CG; n=13) that comprised the animals that received 2mL of physiological solution at the same date of TG. Blood samples were collected on the parturition day for the assessment of serum fructosamine, cholesterol and triglycerides, insulin-like growth factor type 1 (IGF-1), the oxidative stress index (OSi) and blood zinc concentration. In addition to these parameters, the measurement of zinc was made in food given to the animals. There was no difference in metabolic parameters and OSi between the experimental groups (P>0.05), as well as in blood zinc concentrations (P>0.05). The parenteral zinc edentate does not change the energy and oxidative profile of sheep in immediate postpartum.
