​

Our performance recording is based on the common Swedish system for performance recording of registered Gotlands..

Sweden has 4 different recording schemes: Pelt breeds

Pelt breeds, i.e Gotlands & Leicester  (Swedish developed variant of white L.longwool) are recorded, using all the parameters above.

Wool breeds, such as Finnsheep, Rya (not bred for pelts/furskins) have a similar scheme but separate wool evaluation parameters.

Registered Meat breeds  & Cross breeds record same data, except for the wool parameters.

Estimated Breeding Values in Sweden are breed specific and a registered individual is compared against a large reference population within the breed (normally all registered sheep of the same breed, born within the last 10 years).
