Reproductive technologies in cattle including artificial insemination, embryo transfer, and sexed semen have welfare implications that require careful assessment alongside their productivity benefits.
Reproductive technology welfare assessment requires examining the experience of animals at each procedure step: AI causes brief handling stress; CIDR insertion and removal causes brief discomfort; synchronisation protocols involve repeated interventions. Embryo transfer donor welfare is most significant - repeated superovulation cycles cause physiological and handling stress. Limiting cycle frequency and using appropriate analgesia for intrauterine procedures protects donor welfare.
