The goal of this study was to quantify, by morphometric method, the collagen of maternal and fetal portions of dairy cows placentomes with normal delivery and with placental retention. Twelve cows were used and a placentome was obtained from each one soon after fetal expulsion. Eight cows showed normal placental delivery (Group 1) and four cows showed placental retention (Group 2). From each placentome a fragment was obtained, histologically processed and stained by Masson’s Trichromic. Volumetric proportions of maternal and fetal collagen were determined with a 25 point ocular (Zeiss K PL ocular 10xwith 25 points). There was no significant difference between groups (p>0.05) in volumetric proportion of maternal collagen (34.57 ± 5.47 and 32.04 ± 5.82, respectively) and in volumetric proportion of fetal collagen (9.85 ± 2,04 and 10.73 ± 2.47, respectively).
