Spring is approaching and the days are starting to get longer, we know what that means around the barn—foaling season is almost here!
Many broodmares are entering their final months of pregnancy, and now is a great time to make sure everything is in place for a smooth and successful foaling season.
Pneumobort K (Equine Herpes Virus): Vaccinate at the 5th, 7th, and 9th months of pregnancy. Please call the stable at 406-727-9061 to schedule these vaccines.
Pre-Foaling Boosters (about 1 month before due date): 6-way vaccine and strangles.
Rabies: Recommended between foaling and breeding back.
Caslick: If you mare has a caslick, ensure you bring her in about 1 month prior to have it removed.
Time spring deworming about one month before foaling.
If your mare is due soon, now is the time to get your foaling plan ready.
Every mare is a little different, but common signs that foaling may be appraching include:
• Udder development and waxing of the teats
• Softening around the tailhead and relaxation of pelvic ligaments
• Increased restlessness, pacing, or lying down and getting up repeatedly
• Milk dripping or running (contact us if this happens before foaling as mares may be losing vital colostrum)
If your mare appears in distress, has been actively laboring for more than 30 minutes without a foal, or you notice anything abnormal (such as only one leg presenting or a red-bag delivery), contact us immediately.
Early intervention can make all the difference.
After the Foal Arrives: we like to remember the “1-2-3 rule” for newborn foals:
• Stand within 1 hour
• Nurse within 2 hours
• Pass the placenta within 3 hours
If any of these milestones aren’t met, please give us a call.
Our emergency line for after hours is: 406-868-5571
