Background: Coffee pulp has a high content of antioxidants capable modifying the oxidative status in small ruminants. However, amounts for prolonged time can reduce fertility. Objective: To determine effect two inclusion levels coffee during estrous synchronization on reproductive variables and primiparous ewes. Methods: Sixty Suffolk x Dorset ewes were distributed into three treatments completely randomized design; T0: (n=20) 1.5 kg balanced diet, Tl: diet 5% pulp, T2: 10% pulp. Supplementation was given 16 days before estrus until beginning breeding season. A progestogen (CIDR®) inserted ll dose PGF2a applied prior to its withdrawal. Estrus detection started 12 hours after CIDR Blood samples obtained supplementation period measure status, antioxidant capacity, glucose insulin, up 9 progesterone concentration. Pregnancy diagnosis performed at 30 60 post-breeding. An analysis repeated measures mixed effects frequency carried out. Results: Inclusion short did not affect parameters, nor progesterone, or insulin concentrations (p>0.05); however, capacity increased, while lipid oxidation showed an opposite trend (p<0.05). Conclusion: ewe lambs improves without causing adverse pregnancy, prolificacy.
