摘要

•Rebreeding is one of the major challenges to improve the productive efficiency of Brazilian Nellore cows.•Consecutive rebreeding ability is as a new multi-categorical trait associated to the female fertility.•Consecutive rebreeding ability is a feasible indicator of Nellore fertility for long-term selection.•Consecutive rebreeding ability has high genetic association with stayability.
