Contagious Equine Metritis (CEM)

All mares are required to have a clear swab in the current breeding season. A copy of the result is to be sent to the stud prior to the mare's arrival.

Equine Viral Arteritis (EVA)

All mares are required to be blood tested for EVA within the 28 days before arrival at Stud. A copy of the blood test result is to be sent to the stud prior the mare's arrival.

Strangles (Streptococcus Equi)

All mares are required to be blood tested for Strangles within the 28 days before arrival at Stud. (Blood test should be sent to the Animal Health Trust in Newmarket). A copy of the blood test result is to be sent to the stud prior to the mare's arrival.

EHV1-4 (Equine Herpes Virus)

Whilst it is not compulsory, vaccinations for foaling mares are recommended and should be carried out at 5, 7 and 9 months from insemination. Please advise us if your mare requires vaccinating whilst at the stud and we will arrange for this to be carried out. For mares that have been vaccinated against EHV, a written confirmation of a negative pre-vaccine blood test should be sent to the stud prior to arrival.

Equine Influenza/Tetanus

Highly recommended but not compulsory.

The stud will refuse entry to mares that have not had the results of the swabs/blood tests sent in advance.

Artificial Insemination

Mares are taken at livery for AI with fresh or chilled semen. Mares should ideally arrive just before they are due to come into season. They will then be regularly scanned to obtain the optimum timing for insemination. It is stud's policy to scan all mares.

The stud cannot accept responsibility for semen that does not arrive on time, is incorrectly labelled, in poor condition or does not have the correct paperwork.

Veterinary / Emergency Fees

All visits, treatments, medicines, vaccinations and veterinary stud work will be carried out by the Stud Vet (John Brook Equine Clinic) and the owner charged accordingly. In the event of an emergency, all reasonable effort will be made to contact the owner prior to treatment. However, in the event of the owner being unavailable, John Brook Equine Clinic will administer the appropriate treatment deemed necessary for the mare/foal and the owner charged accordingly. If the Emergency Services (e.g. Fire Brigade) are called out, all associated costs will be met by the owner. All veterinary / emergency fees will be invoiced directly to the owner.


All hind shoes are to be removed unless for remedial reasons. In these instances the mare will be turned out in an individual paddock and an additional charge will be incurred.

Feet will be trimmed regularly whilst the mare / foal is at livery and the owner charged accordingly. Any specific shoeing/trimming requirements should be notified to the stud on arrival.


All mares are to be wormed or to have a clear egg count in the 14 days prior to arrival. If an egg count has been carried out, the stud requires sight of the result on arrival. It is the stud's policy to carry out worm egg counts (carried out by the Stud Vet) and wormed accordingly at the owner's expense. Mares that are not wormed prior to arrival will have a worm egg count on arrival, be wormed according to the result and be stabled until all necessary treatment has been administered at the owner's expense.


It is a legal requirement for all horses to have their own passports. Therefore ALL mares must arrive with their own passport, otherwise the stud reserves the right to refuse entry. All passports issued after 1 July 2009 require the horse to be micro-chipped. Foals may travel on their dam's passport up to the age of 6 months.


All fees must be paid in full prior to the mare and/or foal departing. These may include livery (including additional feed if deemed required), farriery, in-foal fee, AI (not veterinary e.g. swabs, drugs) associated costs. Invoices will be raised every 28 days and is to be paid within 14 days of receipt. Payment can be made by cash, cleared cheque or e-banking. In the event of non-payment, the stud reserves the right to charge a daily interest at the rate of 2.5% accrued until the account is settled.

Any insemination resulting in an embryo/foal shall remain the property of Mill Farm Ashorne until all fees have been paid in full and cleared into the nominated bank account.


It is highly recommended that all mares/foals are insured by their owners. Whilst every care and attention is taken, Mill Farm Ashorne can accept no responsibility for visiting mares and foals in relation to theft, accidents, disease. All mares that have any AI work, veterinary treatment/attention, are foaled, prepared for covering, do so at the owners risk. Horses staying at livery, do so at the owner's risk. Mill Farm Ashorne does not guarantee successful pregnancy. Owners should advise their insurance companies that the mare is at livery at Mill Farm.

The stud reserves the right to refuse entry to any horse for any reason and also to request that a horse leaves if the stud considers that horse to be putting the health and safety of personnel and other horses at risk.

Other Notes

All prices are per horse unless otherwise stated. Week prices are calculated at 7 days or part thereof. Discretion will be used for less than 3 days.

The Stud reserves the right to charge an additional hay/feed levy in the event of extreme weather or where additional feed is considered to be in the horse's best interest.

All Stabled, full livery horses, are allocated 3 bags of bedding per week. Any additional bedding used with be charged at the current rate.

It is the stud policy to scan mares at 15 and 28/30 days post insemination to confirm pregnancy and heart beat. However if the mare leaves before the 28/30 day scan it is the owner's responsibility to ensure this is carried out.

All foals will receive regular handling and feet trimming.

An additional charge may be applied for handling difficult mares due to the number of people involved.

Charges are subject to review on 1 April and 1 October each year and may also change within that time due to the global cost of feed/bedding.
