They also give advice to members of the Society on their flocks, their breeding policy and any aspect of flock management. They are also responsible for ensuring that judges appointed by the society are undertaking their duties properly and professionally.The Field Officer also provides technical information to the Society on various aspects of breeding and keeping sheep and the current advice can be accessed using the links at the end of this page.

Tay-Sachs in Jacob Sheep 

The Society has had a watching brief on Tay-Sachs in UK Jacobs since it was brought to our attention in 2011. Tay-Sachs is a genetic disorder like cystic fibrosis or haemophilia that is carried in a very small proportion of the population. It is found in humans, dogs, cats, flamingos and Jacob sheep. Limited information has been available until scientific papers on Tay-Sachs in UK Jacobs were published in October 2013 and February 2014. Following the March 2014 JSS Council meeting, Council Members formed a strategy and communications plan based on protecting the welfare of Jacob sheep and also the interests of our members. Working with colleagues in the veterinary community, researchers at Cambridge University and DEFRA Animal Health, and with the guidance and determination of Chris Lewis (a noted sheep expert and retired vet), the JSS has funded the creation of a UK test to identify Tay-Sachs in Jacobs. The test is voluntary and is now available to members who wish to test their stock.  Members should click on the home page of this website then click on the 'search for members or sheep' button which will take members to their own log in page for registrations. After logging on, Click 'Manage my flock' and it will take you to the Tay-Sachs DNA test option. Carefully select the registered sheep from your flock list to sample, add them to your basket and pay through the check out. Grassroots will be able to help with any dispatch or returns queries through the normal contact routes. Results are anonymous and confidential between members and their vets and members will pay their vets for the service. We do not know how widespread Tay-Sachs is. Carriers of the genetic disorder show no symptoms but a small number of the progeny from two carriers may develop the disorder which is fatal. Any unexplained deaths in 6-8 month old lambs should be checked for Tay-Sachs. The JSS Council has a continuing strategy to monitor Tay-Sachs. At present, we would encourage members to at least get their rams tested as by doing so the potential spread of Tay-Sachs can be restricted. If you need help or advice, please contact Gordon Connor, our Field Officer, on 01506 834806, mob: 07831 492890 or The cost of the test is payable by members who will arrange the testing and submission via grassroots. All associated Veterinary costs are payable directly between the member and your flock vet. A further document for herd vets and members is avaialble here and here  and aan

  Pleaase do not contact the Lab direct. The Field Officer can provide help with interpretation of results and with breeding advice.

Breed Standard 

General Appearance

The Jacob sheep is an alert, active sheep being upstanding and deep bodied, white with well-defined black patches. The head and neck are generally black with a white blaze on the face extending down the chest. Both sexes are horned.


The head should be clear of wool forward of the horns. All sheep should have a clear white blaze. A symmetrical blaze with even black cheeks is preferred.In adult sheep, a pink nose in conjunction with a broad white face is undesirable. A dark nose is preferred. Ears preferably black. Dark bold eyes are preferred with no tendency to split eye-lid deformity. Ewes should have a fine feminine appearance, whilst rams should be thicker set and masculine.


Jacob sheep are always horned, with either two or four in number. Where there are four, the top pair should grow upward from the top of the head and have no forward growing tendencies. There should preferably be space between the top and lower horns. Where there are just two horns there should preferably be space between the roots of the horns at the crown of the head, and grow so as to leave space between horn and cheek. Black horns are preferred. Horns should at all times give the animal freedom from injury and comfort when feeding.

Body & Neck

The back should be straight, level from the base of the neck to the setting on the tail, which should be broad. The tail should be set well up on the chine with well-developed thighs and well-sprung ribs to form a good bottom line. The neck should be strong, of medium length and well set on the shoulders.


Legs are medium boned and of medium length, clear of wool below the knee and hock. Legs should preferably be white with little or no black.


The fleece is of a medium quality, white with well-defined black patches. It is preferred that the skin beneath the white wool be pink, and black beneath the dark wool. There should be little or no kemp. Mottled wool and skin is undesirable.
