Sampling included all breeds
and breed groups of sheep in the Nordic countries, except for recently
imported commercial breeds that are bred in greater numbers in other countries.
Organisation of the populations is connected to already existing projects
that are underways in Norway and Finland. Analysis of data from the Nordic
project included data from those projects as well.
Blood samples were collected from 30 animals pr. group, 20 ewes and 10
rams where possible (rams were sampled in Norway and Finland). The samples
were drawn at random under the restriction of no common grandparents.
Blood was collected into four 10 ml vacutainers from each animal. DNA
was extracted from 20 ml of blood and 20 ml was kept as reserve. DNA from
each animal was deposited at NGH
for future references.
Further use of DNA samples and
genotyping data obtained within the project is administrated by NGH.
Information on the background of breeds and animals was collected according
to the FAO guidelines
on genetic diversity studies. (Questionarie)
The organisation of sampling and the collection of information on background
and individual animals was the responsibility of the country where the
breed is located. This was carried out in co-operation with the relevant
organisations and institutions such as GR committees, sheep breeding association
and others depending on the situation in each country.
