Bovine Reproductive Welfare: Oestrus Detection and Management

Key Welfare Facts

Reproductive failure causes cows to remain in negative energy balance longer, increasing metabolic disease risk.
Oestrus detection technology including pedometers and activity monitors improves detection rates without hormonal intervention.
Fixed-time AI synchronisation protocols require multiple hormonal interventions with associated handling stress.
Progesterone supplementation of sub-fertile cows requires repeated visits causing significant handling-related stress.
Fertility indicators including body condition, lameness prevalence, and calving ease reflect reproductive welfare status.
Voluntary waiting period management allowing natural recovery before breeding optimises welfare and fertility.

Welfare Assessment

Reproductive welfare management requires balancing fertility goals with welfare impacts of hormonal interventions and handling frequency. Optimising voluntary waiting periods and investing in technology-assisted detection reduces pharmacological intervention while maintaining acceptable fertility rates.

What You Can Do

Invest in activity-based oestrus detection to reduce dependence on hormonal synchronisation protocols
Implement appropriate voluntary waiting periods to allow cows to recover body condition before breeding
Monitor body condition score and lameness as key reproductive welfare indicators across the herd
Work with a herd health vet to develop reproductive programmes balancing welfare and fertility targets
