Lingfield Equine Vets provide a complete stud medicine service to ensure you find as much support as you need. We provide care right the way from assessing suitability for breeding, through pregnancy to foaling. Our team are experienced in managing foals and young stock, so you can be confident that we are here for you every step of the way. 
  

Artificial Insemination (AI)

AI creating a pregnancy without using a stallion to cover the mare naturally.  There are several reasons owners decide to go down this route rather than natural cover:
  • you may prefer not to send your mare away to stud
  • you may be concerned how your mare will react to being mounted by a stallion
  • the chosen stallion may only offer breeding by AI for temperament, fertility or competition reasons or
  • you would rather use semen from a stallion located in another country or even continent!

Whatever the reason, should you chose to pursue breeding by AI, we can help provide you the information you need to ensure the process is as smooth and exciting as possible.

We are a registered British Equine Veterinary Association (BEVA) approved centre for AI using fresh, chilled and frozen semen. To make life easy for you, we offer a number of packages for all our reproduction work.  We will also take care of all semen handling at no extra cost, including storing your chosen stallion's frozen semen during the breeding season for you FREE OF CHARGE. 

Sometimes nature doesn't play along and more than one AI cycle might be necessary to get your mare in foal. We offer discounted fees for repeat AI cycles, along with a further 5% discount to people who settle their fees when the mare is collected/following insemination.


Protecting your horse's health

Health testing every mare and stallion prior to breeding is imperative to ensure we do not spread disease.  These diseases can result in fertility problems and abortion, so we take health screening very seriously.  We have clear guidance on these requirements given to us by the RCVS and BEVA, and it is in place to protect your horse. As such, is it our practice policy to ensure every mare we AI has a CEM certificate valid for the current breeding season. Semen received for use by our vets must be accompanied by the appropriate paperwork including negative results for CEM. If this is not present the semen will not be inseminated into the mare.  
 

Embyro Transfer (ET)

Our vets are experienced embryo flushing for transfer.  ET is a technique by where the embryo is flushed out of a donor mare and then transferred very carefully into a recipient mare. This all sounds pretty straightforward but it's not quite as easy as it sounds.

The donor mare first has to be carefully prepared with pre-breeding assessments and an AI or natural cover.  At the same time 3-4 recipient mares are also being prepared and synchronised with the donor mares.  Because most owners do not have a plethora of mares hanging around waiting to be a surrogate mummy, we often recommend teaming up with a larger specialist facility such as Twemlows Stud Farm Embryo Transfer Centre, who can offer recipient mares to you as part of an ET package.

Historically, mares have been required to travel huge distances for ET; however we can now offer embryo flushing on site, shipping the embryo to the recipient mares, taking the travelling factor out of the equation for you and your mare.  We offer competitive embryo transfer packages, please contact us to discuss ET further.
 

Pregnancy Diagnosis and Twin Management

Pregnancy diagnosis is most commonly and reliably performed using an ultrasound scanner.  This allows for the detection of a pregnancy as early as 12 days.  It is advisable to have two examinations performed – the first scan at 14-16 days after covering/insemination; and the second at 28-30 days. Scanning not only diagnoses pregnancy, but also allows us to detect and treat twins.  Should twins be present one of the embryos should be reduced leaving only one embryo.  If a twin pregnancy continues, it is most likely the mare will either resorb the pregnancy completely, or one foetus with die during pregnancy resulting in abortion.  It is easier and safer to address twinning before 17 days of pregnancy, hence the need for early scans.

Additional scans at other dates may be recommended.  For example, high risk pregnancies, may be scanned more often (every week or so) until 30 days and then again at 40-50 days.  Scanning at autumn is sensible to confirm your mare is still in foal prior to the stud fee being paid.

We also offer a late gestation scan within 4 weeks of the expected foaling date.  This actually includes two scans: per rectum and externally through the mare's belly.  At this stage we assesses the foal's heart beat and health by monitoring the movement.  The position of the foal within the uterus does not change between now and foaling, so hopefully we can reassure you that a head first/feet first presentation is likely.  If the foal is seen to be in a breach position precautionary arrangements are strongly recommended as it is highly likely a caesarean procedure will be required.
