Artificial insemination is nearly universal in dairy cattle and widespread in pigs and other livestock, with welfare implications for both donor and recipient animals that require attention.
Artificial insemination welfare encompasses several distinct procedures. Semen collection from donor males varies in aversiveness by method and species. Reproductive management of females through hormone synchronisation involves multiple handling and injection events causing handling stress. Pregnancy diagnosis by rectal palpation, long standard practice in cattle, involves significant discomfort and occasional injury risk to the rectum. The shift to ultrasound-based pregnancy diagnosis is a meaningful welfare improvement. The concentration of genetics through AI also creates population-level welfare risks: when elite sires carrying heritable conditions are used millions of times, the welfare consequences propagate throughout the entire production sector. Responsible genetic selection requires active monitoring for heritable welfare conditions.
