The aim of this study was to evaluate the influence of the administration of propylene glycol and cobalt associated with vitamin B12 on the metabolic profile and enzymatic activity of Santa Inês ewes in the peripartum period. A total of 18 pregnant ewes, weighing around 40kg were used. Approximately 30 days before the expected date of delivery were randomly separated into three groups and administered supplements as follows: (G1/n = 6) group received propylene glycol (30mL orally daily); (G2/n = 6) group receiving cobalt (1mg cobalt chloride 1%, orally daily) associated with vitamin B12 (2mg intramuscular weekly) and (G3/n = 6) control group. Blood samples from ewes to evaluate the enzymatic and metabolic profile (glucose, β-hydroxybutyrate, BHB, NEFA, total protein, albumin, urea, creatinine, AST, GGT, ALP and CK) were taken 30 days before the date set for delivery, one week before (ante partum), delivery at 24h, 72h, 5 days, 15 days and 30 days after delivery. ketonuria was not observed in pre partum. The administration of supplements had no effect on the metabolic profile, protein and energy, and no liver disorders was observed in peripartum.
