Abstract excerpt
Timed artificial insemination (TAI) protocols have revolutionized reproductive management in dairy cattle, but their interaction with genetic factors affecting fertility traits remains poorly understood. This study was performed to investigate whether TAI protocols influence the genetic architecture of fertility traits compared with traditional heat detection (HD) systems. The dataset included 3,842 reproductive...
