Thirty-six pregnant Santa Inês ewes, with an average age of 24 months and initial weight of 46.54±7.87 kg, were used. A completely randomized experimental design was used, with three treatments: CS, concentrated supplement; G5, concentrated supplement with 5.5% protected fat (PF); and G10, concentrated supplement with 13.5% PF. The productive performance parameters were evaluated every two weeks. At 60 days after parturition, the chemical composition of milk and the reproductive parameters were determined. The inclusion of PF in the concentrate did not affect the following variables: body weight, body condition score, service period, lambing to first estrus interval, and chemical composition of milk. The supplementation with or without PF allowed ewes to keep body weight until 60 days after parturition, which improved their body condition score. The inclusion of PF in the concentrate does not change the productive performance of confined Santa Inês ewes; however, it affects reproduction by resulting in lower probability rates of pregnancy  aSuíno  aÁcido graxs poli-insaturado  aPeso corporal  aSuplementação1 aGODOY, M.
