PERFORMANCE RECORDING OF GOTLAND SHEEP
Here is an overview of all data collected in our Gotland sheep flock for performance recording.
No of lambs born
Ear tag / Id no registration (individual, trace back to flock no)
Recording of litter data for each ewe + ear tag no of each lamb
Registration of lamb ear tag no links each lamb to pedigree /background data for sire/dam
Weight @ 60 days
Weight @110 days
a) Quantitative Colour i.e the (mainly) visible colour.
b) Qualitative Colour: Uniformity of the colour over whole body and full wool length
2. Curl a) Size - Quantitative b) Shape - Qualitative
3. Wool Quality (qualitative)
4. Wool Distribution (quantitative)
5. Overall / Total Score

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).
Cross breed sheep get their own EBV´s compared to a specific reference population.
