Reproductive management in dairy cattle involves hormonal manipulation, artificial insemination, and pregnancy diagnosis that each carry welfare implications requiring careful management to minimize harm.
Reproductive management of dairy cows involves repeated physical interventions throughout the production cycle. Hormonal synchronization protocols require multiple injections over days to weeks, each causing handling stress and sometimes local discomfort. Dystocia during calving causes severe pain and can result in injury or death for both cow and calf without veterinary intervention. Retained placentas cause painful uterine infection. Metritis treatment often requires intrauterine infusions that cause additional discomfort. Improving the overall health and body condition of cows reduces the frequency and severity of reproductive disorders, simultaneously improving welfare and production outcomes. Fewer unsuccessful breeding attempts mean fewer handling events and less hormonal manipulation per cow.
