As the breeding season begins, we at Stringer Equine have one goal and that is to have a healthy foal from every mare under our reproductive care. If any of the below points apply to your mare, or if you are considering breeding for the first time, please contact us to discuss what would be best for your mare.
IF YOUR MARE DIDN'T GET IN FOAL LAST YEAR:
As the breeding season begins, if your mare didn't have a successful pregnancy last year it is worth considering several factors before trying again.
There are many many reasons why a mare would fail to conceive / hold a pregnancy and we advise taking a pro-active - and early! - approach to addressing some of these:
- Pre-breeding examination: What condition was your mare in last year β mares in poor body condition, or too fat, can have significantly lower conception rates (in our experience the latter is far more common). A thorough examination by an experienced stud vet prior to making any decisions re: breeding can be invaluable. An assessment of perineal conformation, an internal examination of va**na and cervix, and ultrasound examination of uterus and ovaries as well as a look at the overall health and condition of the mare is a good place to start. In older mares blood testing for PPID (Cushings) is advisable before starting on a breeding programme.
- Cytology & culture: Swabs and smears from the uterus to check that the mare is clear from infections prior to starting breeding can save wasted time and money. This is usually performed at the start of any assisted breeding cycle and would be especially useful if the mare had failed to conceive the prior season.
- Biopsy: A uterine biopsy may be done as part of an infertility work-up and can reveal infections, damage, and/or age related changes.
- Does your mare need more intervention? Those mares sent for natural cover who fail to conceive may have an increased chance of a successful pregnancy with supplemental progesterone, antibiotics during pregnancy, caslicks procedure or uterine lavage post-cover / AI.
- Laser ablation of uterine cysts: This procedure has been proven to increase fertility in mares and is definitely worth considering if your vet mentioned finding cysts last year, or if they are discovered at a pre-breeding exam. Donβt panic! Cysts do not equate to infertility and many mares with cysts carry successful pregnancies but, if your mare is having problems AND has cysts then studies have shown that addressing these can improve fertility.
- Method of breeding: Mares who don't hold to a natural cover may benefit from the increased supervision of an AI package. Chilled semen has a higher conception rate per cycle than frozen.
- Stallion factors: Semen quality is always checked at the time of insemination. Sometimes there is a mare/stallion incompatibility.
- Embryo transfer: We offer embryo transfer which can be useful for those mares who repeatedly become pregnant but fail to reach a confirmed heartbeat stage. In these instances a pregnancy can be removed early and (hopefully) implanted into a recipient mare to carry it to full term.
We are a BEVA approved practice for AI, and with our experienced stud vets we would be delighted to work with you this breeding season.
