The experiment was conducted from August 2011 to May 2012 in the Sheep Sector, Federal University of Sergipe. Aimed to study the effects of the transition period on dry matter intake, milk production, body condition score, body weight and metabolic profile, characterizing the transition period in Santa Ines sheep. We used 10 ewes, nullíparas, pregnant. The animals were confined to 30 days before expected farrowing until 60 days after delivery. To study the variables CMS, CMS (% BW), weight, BCS and metabolic profile were analyzed in three periods: Period 1: animals of 21 days pre-partum until delivery; Period 2: animals calving until 21 days postchildbirth; Period 3: animals over 21 days postpartum. Variables related to milk production (kg milk / day, kg corrected milk at 3.5% fat / day, fat percentage and fat yield in kg) were divided into two periods: PL30 (birth to 30 days); PL60 days (30-60 days postpartum). There were significant differences (P <0.05) in CMS and CMS (% PV) between the periods studied, with higher consumption in period 3, with a mean of 1.58 ± 0.07 kg and 2.83 ± 0.16% , respectively. Body weight and BCS showed significant differences (P <0.05) in period 1, with average 55.28 ± 1.12 and 3.34 ± 0.06 respectively. The results of the production and milk composition (PL, PLC, Gkg, G%) were similar between periods of lactation (P <0.05), with maximum efficiency in PL30. There was no significant difference (P> 0.05) variables of the metabolic profile (glucose, total protein, urea, albumin, triglycerides and AGNE). The transition period in Santa Inês ewes was featured 21 days pre partum and 21 days postpartum.
