The intravaginal progesterone device is the most expensive of the estrus synchronization protocol, which may make it impossible for the producer to access this biotechnology. The aim of the present study was to compare the pregnancy rate between implants with new devices and fourth use in two farms in Amazonas. Data were acquired through the MultBovinos® program. The results show a pregnancy rate of 56.06% for new devices and 67.14% for fourth use on Farm 01 and 67.09% for new devices and 70.97% for fourth use on Farm 02. Therefore, the reuse of 1.9 g progesterone intravaginal implants obtained better pregnancy rate results when compared to the first use.
