Pregnant Mare/Post Parturition Care Services
- Removal of retained fetal membranes, treatment, and uterine flushing
AAEP Recommendations for Pregnant Mares:
- Vaccines should be current
- Booster vaccinations should be given 4-6 weeks before expected due date
(to increase antibodies in colostrum)
- Deworm 3-4 weeks before expected due date
(consult your veterinarian for pregnant mare safe dewormers and scheduling)
- Move pregnant mare to foaling location 3-4 weeks before expected due date
(to help mare settle in and to enhance immunity against environmental pathogens)
Information About Pregnant and Foaling Mares
Services to Prepare Mares for Breeding
- Artificial/supplemental lighting program (limited availability)
-- Box stalls with sufficiently bright lights (on timers) provide 16 hours of light per day to induce cycling in mares
- 60-90 days required to start cycling (Start under lights at home on December 1, in order to begin breeding by February/March)
- Reproductive soundness examinations
(Recommended for mares with unknown or questionable fertility, maiden mares, postpartum mares, and barren mares.)
-- Examination of external genitalia and mammary gland
-- Manual and visual vaginal examination
-- Palpation and ultrasonography of internal genitalia
-- Culture and cytology of endometrial swab/sample
- Problem mare diagnostics and therapy
-- Endometritis (uterine inflammation and retained fluid)
-- Endometrial changes (scar tissue, inflammatory cell accumulation, cysts, and destruction of uterine glands)
-- Poor perineal conformation (windsucking, urine pooling)
-- Failure to display estrus (in anestrus, granulosa-theca cell tumor on ovary, gonadal dysgenesis [congenital defective development of reproductive tissues, fibrous functionless tissue], pituitary adenoma)
-- Silent heat (maiden mares and mares with foals at side ovulate without showing behavioral estrus)
-- Failure to ovulate (anovulatory follicles, persistent follicles)
-- Failure to cycle (anestrus, inadequate nutrition, poor body condition, lactation, postpartum anestrus)
-- Persistent corpus luteum or CL (pseudopregnancy)
-- Luteal insufficiency (CL doesn't produce sufficient progesterone)
-- Parovarian cysts (mimic appearance of preovulatory follicle)
-- Equine metabolic syndrome or Cushing's Disease
-- Chromosomal abnormalities (XO & XY cause small inactive ovaries, autsomal translocations are known to cause repeated early embryonic loss)
-- Administration of certain hormones (anabolic steroids, GnRH vaccination)
Breeding Options
- Artificial insemination with cooled shipped semen
-- Able to receive shipments via FedEx, UPS, and MSP airport
- Artificial insemination with frozen semen
-- Frozen semen storage on site
-- Employment of specific protocol for breeding with frozen semen
- Use of ovulation-inducing agent
- Increased ultrasound monitoring (every 4-6 hours nearing ovulation)
- Deep horn insemination technique (within 4-6 hours of ovulation)
- Post-ovulation ultrasound monitoring to ensure fluid clearance
-- Recipient mare herd on site
All fees for breeding(s) are due when mare(s) are dropped off.
All other expenses, such as board, are due when mare(s) are picked up!
