Horse Pregnancy and Foaling Welfare

Mare pregnancy and foaling involves specific welfare considerations around nutrition, monitoring, and emergency intervention to protect the welfare of both mare and foal.

Key Facts

Mare gestation averages 340 days with normal range from 320 to 360 days
Mares showing signs of foaling readiness should be monitored frequently - foaling can progress rapidly
Dystocia occurs in approximately 4% of equine births and rapidly becomes life-threatening without intervention
Normal foaling from first signs to birth typically occurs within 30-60 minutes
The foal should be standing within 1-2 hours and suckling within 3 hours - failure to do so requires intervention
Retained placenta beyond 3 hours is a veterinary emergency requiring prompt treatment
Premature foals born before 320 days require intensive veterinary support for survival

Welfare Considerations

Foaling is a high-risk welfare event for both mare and foal. Dystocia causes extreme pain in the mare and can cause death of both mare and foal within hours without assistance. Foals that fail to stand and suckle in the expected timeframe rapidly develop hypoglycemia and septicemia. Retained placenta causes severe uterine infection and can progress to laminitis and septicemia in the mare. The high stakes of the foaling period justify intensive monitoring and access to emergency veterinary support. Well-prepared foaling management that detects problems early and enables prompt intervention prevents the most serious welfare harms.

What You Can Do

Monitor mares closely in the final weeks of pregnancy for signs of udder development and waxing
Check mares every 1-2 hours during the active foaling period once stage 1 labor is confirmed
Call your veterinarian immediately if stage 2 labor (red bag or visible membranes) lasts more than 20 minutes without delivery
Check that the foal is standing, nursing, and has passed meconium within expected timeframes
Seek veterinary attention immediately for retained placenta beyond 3 hours
Have veterinary contact numbers readily available throughout the foaling period
