Signs Preceding Foaling in Mares

Foaling in mares, also known as parturition, is a critical moment that requires special attention. Recognizing the warning signs can make all the difference in ensuring the safety of the mare and foal. Here is a complete guide to the behaviors and physiological changes to monitor in the final days of gestation.

The weeks leading up to foaling

About 2 to 6 weeks before term, you may observe:

• - Significant development of the udder (mammary glands)
• - Relaxation of the muscles around the croup and tail
• - Slight sagging of the abdomen

The days leading up to foaling

In the 7 to 10 days before foaling:

• - The udder continues to develop and becomes firmer
• - Formation of wax at the ends of the teats (about 24-48 hours before)
• - Production of colostrum (first milk produced by mares), which may sometimes leak
• - Noticeable relaxation of the pelvic ligaments
• - The vulva lengthens and relaxes

The hours leading up to foaling

In the final 24 hours:

• - Increased restlessness and nervousness
• - The mare may frequently look at her flank
• - Sweating, particularly around the neck and flanks
• - Frequent urination
• - Loss of appetite
• - Pacing back and forth in the stall
• - Pawing the ground with the front hooves

Immediate signs

When foaling is imminent (less than an hour away):

• - The mare lies down and gets up frequently
• - Visible abdominal contractions
• - Rupture of the amniotic sac (clear fluid)
• - Characteristic position: lying on her side with legs extended

The importance of monitoring

Despite all these signs, some mares can be very discreet and show few clues before foaling. This is why careful monitoring is essential, especially at night when the majority of foalings occur.

Monitoring systems like FirstBreath can detect these subtle signs and alert the breeder at the right moment, providing peace of mind and significantly increasing the chances of a complication-free foaling.
