Twenty Santa Inês ewes used to evaluate effects of oral administration of Brazilian red propolis extract on blood metabolites, milk production, and lamb performance were randomly grouped (n = 10 ewes/group) to control without propolis administration and propolis treated (3 g red propolis extract/ewe/day) 21 days before expected lambing date. Blood samples were collected weekly, and daily milk yield was recorded twice weekly until 7 weeks postpartum. Propolis administration increased (P < 0.05) total leukocyte counts, protein, and globulin and glucose concentrations, decreased (P < 0.05) somatic cell counts, and enhanced (P < 0.05) yields of milk, fat, protein, and lactose. Propolis supplementation increased (P < 0.05) average daily gain and milk conversion ratio but had no effect on lamb birth and weaning weights. The prepartum administration of propolis extract supported positively the transition of ewes from pregnancy to lactation with health benefits achieved for both of ewes and lambs performances.
