The present work summarizes different livestock activities in the Empresa Láctea S.A. in which the author had participation as an employee in charge of the reproductive part of the cattle barn and that has served to gain experience and skills as a graduate in Veterinary Medicine and Zootechnics from the Antenor Orrego Private University. In the period, May 14, 2013 to September 23, 2017, the records of 12,234 cows that went into labor were analyzed and some reproductive indices were established that will help us design some improvement actions. It was observed that the delivery presentation is very similar during the day and at night. Although the percentage of dystocia deliveries in the period studied was 18%, considered relatively high, this is due to the fact that deliveries with minimal assistance were included as dystocia for precautionary reasons. The absence of dystocia is associated with the productive age and number of lactations and on the productive average. A percentage of abortions of 5% per year is considered acceptable in all livestock operations. The number of abortions is associated with the productive age and number of lactations and on the productive average. We consider placenta retention to be within the usual presentation ranges, despite the fact that in our study retention is considered after 12 hours. The percentages of 75% cures of metritis at 30 days postpartum, although not statistically proven, indicate that the treatment protocols are giving expected results. A better overall index of artificial insemination than the 3.8 inseminations per pregnancy obtained would be desirable, however, the 1.9 in inseminations from the first to the fourth is widely satisfactory, because it allowed to obtain an index of a pregnancy rate of 67%. As expected in a large dairy farm, it is difficult to provide personalized attention to cows and global care protocols have to be established, prioritizing prevention over cure
