Abstract

The use of FTAI in 2021 grew by 24.6% when compared to 2020, reaching 93.3% of inseminations that took place in Brazil. The technique represents a viable biotechnology for commercial livestock and allows the use of semen from superior bulls and optimization of herd pregnancy rates. This report aimed to describe the pregnancy rate of nulliparous and multiparous Nellore. Cows submitted to the fixed time artificial insemination (FTAI) protocol on a property located in the city of Goianira, Goiás. In general, on the property obtained the result of 29 pregnant females, representing 69.05% from 42 sows with the protocol of three managements of D0 (day zero), D8 (day eight), D10 (day ten). The FTAI proved to be an essential biotechnique to improve the productive and reproductive indices of the herd.
