When can mares be Ultrasoundd after breeding?
Your veterinarian can perform transrectal ultrasound as soon as Day 26 of gestation to visualize a heartbeat and confirm fetal viability. Before ultrasound was so widely available, many people relied on the fact that most mares will come back into heat 17 to 20 days after breeding if they have not conceived.
How much oxytocin do you give a mare after breeding?
It should be noted that a post foaling mare has a high up-regulation of the oxytocin receptor. This effect means a smaller dose of oxytocin has a much greater effect. In post-foaling mares, I only use 5-10 IU of oxytocin at a maximum.
How many days after ovulation do we flush the uterus of the donor mare when performing embryo transfer?
between 6 to 8 days
Flushing and transferring the embryo Recovering the embryo from your mare is a simple, non-surgical, painless process that is carried out between 6 to 8 days after ovulation.
What is uterine lavage in mares?
A uterine lavage may be required after breeding or insemination in mares with persistentmating-induced endometritis. The goal is to remove dead sperm, inflammatory cells, debris, and other material and prevent or limit the sperm-induced inflammatory response.
How long does oxytocin last in mare?
The inflammatory response peaks approximately 12 to 24 hours after breeding and a majority of mares will usually reabsorb or expel all of the fluid, dead sperm and debris within 24 to 48 hours after mating.
How late can you ultrasound a mare?
28 day Equine Ultrasound This exam may be variable; it may be done as early as 25 days or late as 35 days.
How long after covering can a mare be scanned?
Rectal Ultrasound The first ultrasound examination should take place at 14-15 days after insemination (or the last date of covering).
How much oxytocin do you give a mare with retained placenta?
Oxytocin can be administered as a slow intravenous (IV) drip, bolus IV injection, and intramuscular (IM) injection (4). The recommended dose ranges from 2 to 120 IU.
How much does it cost to flush a mare?
This is $255 per flush and $360 per transfer. These costs include all reproductive drugs, ultrasound examinations, insemination, and pregnancy tests. Recipient mares will need to be on Regumate after the transfer to help maintain pregnancy.
What is flushing a mare?
Embryo transfer (ET) is the process of flushing an embryo from a mare (donor) and placing it into the uterus of a second mare (recipient) to be carried for the remainder of the pregnancy. The genetic makeup of the resulting foal will be that of the donor mare and stallion, the recipient is merely a “surrogate mother”.
How do you treat a mare uterine infection?
Mares with bacterial endometritis should be treated with i.u. antibiotics for 3–7 days. Treatment length depends on chronicity of the infection, bacteria isolated, the mare’s ability to clear uterine fluid and her history.
How does retained placenta cause laminitis?
Necrotic fetal membranes within the uterus provide an excellent environment for bacterial growth and endotoxin release. If not treated, retained placenta will progress to septicemia/endotoxemia which can lead to laminitis and death.
How often can you give oxytocin to a mare?
Often one or two doses of oxytocin may be administered beginning 2 to 3 hours after foaling to help promote passage of the placenta. If the placenta has still not passed after oxytocin therapy, it is recommended that your veterinarian be contacted for further medical intervention.
How much does it cost to ultrasound a horse?
Each ultrasound will usually cost between $45-$65 depending on your practice’s charges, plus your call fee. So, perhaps plan for $100-$125 for each ultrasound check visit, depending on if sedation is used or not.
How many times should a mare be covered?
To maximise the chance of getting her in foal, the traditional natural breeding strategy is to cover a mare every 48 hours during her heat, beginning on the second day of showing oestrus signs.
How long does it take for oxytocin to work in horses?
Under the appropriate circumstances, administration of low-dose(s) of oxytocin can safely stimulate the delivery of a foal within 30 to 45 minutes in the late-term mare. In summary, oxytocin is one of the most commonly used hormones in equine reproductive management.
What is uterine lavage?
What does it mean to flush a mare?
Can you breed a 30 year old mare?
In general, female horses can breed until they are 25 years old, and male horses can breed up to 30 years old. But some horses may stop breeding either much younger or older depending on their health, fertility, and history.
What is a uterine lavage for horses?
A uterine lavage may be required after breeding or insemination in mares with persistentmating‐induced endometritis. The goal is to remove dead sperm, inflammatory cells, debris, and other material and prevent or limit the sperm‐induced inflammatory response.
When is a uterine lavage indicated in the treatment of endometritis?
A uterine lavage may be required after breeding or insemination in mares with persistentmating‐induced endometritis. The goal is to remove dead sperm, inflammatory cells, debris, and other material and prevent or limit the sperm‐induced inflammatory response. In the postpartum mare, a uterine lavage may be performed in the event…
What is post-breeding endometritis in mares?
Mares that are susceptible to persistent post-breeding endometritis (PPBEM) have impaired uterine defence and clearance mechanisms, making them unable to resolve this inflammation within the normal time. This persists beyond 48 hours post-breeding and causes persistent fluid accumulation within the uterus.
Why do you lavage a mare in estrus?
Mares in estrus may be lavaged one or more days prior to breeding to remove accumulated fluid or as part of a therapeutic plan for mares with infectious endometritis. It is common to lavage a mare with 1–3 liters or more of sterile 0.9% saline or lactated Ringer’s solution (LRS).
