--- The aim of the present study was to evaluate to the effect of the administration of the Cloprostenol Sódico (synthetic Prostaglandin) in dairy cows with opened long days, of the María stable, located in the district of Santa Rita, Arequipa. For the accomplishment of the study there were selected the first group of 25 cows (control) and the second group of 30 cows become (treatment). Both group subdivided in animals with ≤72 opened days y >72 opened days, confirmed the presence of the body luteo in the animals of the group treatment, managed the affairs route IM 0.50mg/animal (2ml) of sodium Cloprostenol waiting for the presentation of zeal in the next 4 days post application, proving to the first dose 86.67 % (26/30) of luteolisis, the second dose was necessary in only 13.33 % (4/30) of the animals. The frequency of presentation of zeal in the treated animals happened in 3.84 % (1/26) in the first 24 hours, 69.22 % (18/26) in the following ones 48 at 72 hours, and 26.94 % (7/26) between the last 96 hours. The occurrence of zeal was of major presentation during the day, 57.69 % (5:00 a.m. - 4:59 p.m.) and 42.31 % (5:00 p.m. - 4:59 a.m.) during the night to be inseminated 12 hours later. In case of the group control respect the occurrence of postpartum zeal applying equal technology of insemination. The results to the diagnosis of gestation shows a significant association between the effect of the treatment and the pregnancy, since the group in treatment with Sodium Cloprostenol achieved 83.3 % (25/30) of pregnant cows, whereas the control group presented 36.0% (9/30) of pregnant cows. The evaluation of the results obtained of the diagnosis of gestation between, you become vacant with ≤ 72 opened days y >72 opened days, they do not present significant difference with regard to rate of conception, 80.0 % and 86.7 % respectively, which indicates that the efficiency of the sodium Cloprostenol would not be influenced by the number of opened days.
