Conteúdo: 	This study aimed to measure the physiological changes in the combined utero-placental thickness (CUPT) during the course of normal pregnancy in Mangalarga Marchador mares. Transrectal B-mode ultrasonography was used to measure CUPT in 42 pregnant mares with a mean age, 8.7 (±3.5 years). CUPT was measured every month from 150 days of gestation until delivery. CUPT was expressed as an average of three measurements of the distance (mm) between the middle part of the uterine artery and the allantoic fluid. A General Linear Model was used to evaluate the major effects of the chronological age and stage of gestation on CUPT in mares. The coefficient of determination (R2) was 0.571 (P < 0.001). There was no correlation between CUPT and the chronological age of the mares, however, there was a positive correlation between CUPT and the stage of gestation, which an accounted for 29.6% of the observed variation. CUPT significantly increased during the gestational period from 210 to 240 days and 270?300 days. These results showed CUPT increased as pregnancy advanced in the Mangalarga Marchador mares. In conclusion these effects of the stage of pregnancy on the increase in CUPT showed a physiological parameters of ultrasonography evaluation of the placenta in Mangalarga Marchador mares.
