%X twenty-four colombian mares from 4 to 14 years of age were inseminated artificially. progesterone (p4) plasma levels were quantified by the technique of solid phase radioimmunoassay (ria); corpus luteum (cl), the uterus and uterine edema were evaluated by ultrasonography from ovulation until day 40 post-ovulation. pregnancy was diagnosed upon detecting a conceptus; it was evaluated daily from that moment until day 40. data were analyzed using descriptive statistics with mean values and standard deviation (sd). pregnancy diagnosis was made on day 10.4 ¡À 0.8 (mean ¡À sd). the conceptus growth rate was 1.65 ¡À 0.1 mm / day; attachment to the uterus occurred on day 16.8 ¡À 1.5. the embryo was visualized within the gallbladder on day 20.8 ¡À 1.7; its growth rate was 0.8 ¡À 0.3 mm/day. heartbeat was detected from day 23.9 ¡À 1.3. 100 % of the embryos had normal development until day 40 of gestation. 62.5 % of the cl was located in the right ovary and 33.3 % in the left; one animal had double ovulation. 66.6 % of the conceptus was located in the right utero corneal junction and 33.3 % in the left;79.1 % ipsilateral to the cl. pregnancy in the mare shows physiological characteristics similar to those described in literature. the data presented here are important for clinical evaluations and provide a starting point for future studies.
