Genomisk kartläggning som redskap för hållbart avelsarbete i inhemska nordiska hästraser

The aim of the project is to characterize genomic diversity and inbreeding, within and between Nordic native horse breeds, with special focus on the Norwegian and Swedish breeds. For this we will use whole genome sequencing of individual and pooled DNA samples. Genomic characterization is an essential first step in describing standing genetic variation within breeds to be preserved, and unique variation between breeds. It can further provide knowledge about genomic regions with unique characteristics and diversity, as well as genomic regions where breeds lack variation and are completely inbred. Therefore, this information can be utilized by breed associations to make well informed conservation and breeding plans. Our research also lays the foundation for further research leading to increased positive synergy in the horse sector.

Målet med prosjektet er å karakterisere genomisk mangfold og innavl innenfor og mellom nordiske hesteraser, med spesielt fokus på de norske og svenske rasene. For dette vil vi bruke hel-genom sekvensering av individuelle og grupperte DNA-prøver. Genomisk karakterisering er et viktig første skritt i å dokumentere nåværende genetisk variasjon innen raser som skal bevares, og unik variasjon mellom raser. Det kan videre gi kunnskap om genomiske regioner med unike egenskaper og mangfold, samt genomiske regioner der raser mangler variasjon og er innavlet. Derfor kan denne informasjonen brukes av raseforeninger til å lage godt informerte bevarings- og avlsplaner. Vår forskning legger også grunnlaget for videre forskning som fører til økt positiv synergi i hestesektoren.

Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of …

Every year, about 500,000 claw trimmings are recorded in Swedish dairy cattle. The aim of claw trimming is to detect, treat and prevent painful claw lesions. However, the claw trimming in itself can be harmful and cause claw lesions if it is not done correctly. The aim of the project is to develop …
