Reproductive management in dairy and beef cattle involves interventions including oestrus synchronisation, artificial insemination, embryo transfer, and pregnancy diagnosis - each with welfare implications. Synchronisation protocols using GnRH and prostaglandin injections enable fixed-time AI without heat detection but require repeated handling and injection stress. Rectal pregnancy diagnosis by experienced practitioners is low-risk, but by novices can cause rectal tears and peritonitis. Superovulation programmes for embryo donors impose hormonal stress and require repeated blood sampling. Bull welfare in natural service systems includes risk of musculoskeletal injury during mounting and social competition. Heifer breeding age decisions balance welfare (avoiding dystocia from breeding too young) against productivity. Research demonstrates that reproductive stress accumulates with management intensity; simplified protocols with fewer interventions improve both welfare and compliance. Precision reproductive monitoring using activity and progesterone sensors reduces unnecessary interventions.
