The objective was to analyze the results of fertility and relate morphology and number of sperm of bulls used in artificial insemination in grazing systems. 12780 backdate services were evaluated with 43 bulls to heifers and cows made from three dairy farms located in the province of Entre Rios - Argentina during the period 2011-2014. The variables evaluated were: sperm morphology, motile spermatozoa per dose, conception rate and number of services per pregnancy. The differences with statistical significance (P ≤ 0.05) were observed in the number of services that were needed to achieve pregnancy and conception rate. The variables taking into account the time of year when services are performed emerged that at the time from the beginning of autumn until spring, the amount of services required by cows and heifers was significantly lower (p ≤ 0.05) and conception rate also increased significantly (p≤0,5) if these variables with the results obtained during the summer are compared. It is concluded that conception rate is not related to the morphology and sperm motility in Holstein dairy cows in systems grazing, however if the time of year in which the services were performed, being less beneficial to service in the months where the ambient temperature he begins to rise.
