Hd grad i England

[Willa]

Hei,

Jeg blir ikke heltklok på HD tallene i England, noen som kan hjelpe? Hva vil det f.eks si at en hund har 8/4 på hoftene mot 3/5 på en annen hund?

Takker for alle svar

Hadde en gang en fin tabell med sammenligning med det norske systemet, men kan ikke finne den. Tallene du kommer med er på de ulike hoftene. F.eks. har den ene 8 på én hofte og 4 på den andre.

Her er litt informasjon om de ulike gradene:

"Total scores

While it is impossible to correlate a hip score exactly with grades of hip dysplasia given under other schemes, an approximate interpretation for total hip scores is as follows (assuming that the two hips are similar):

0 to 4 total score: perfect or near perfect hips

5 to 10 total score: borderline changes that are unlikely to worsen with age

11 to 20 total score: mild changes that may worsen with age, sometimes developing into osteoarthritis

21 to 50 total score: moderate to marked hip dysplasia in which osteoarthritis is already a prominent feature, or severe hip dysplasia before arthritic change.

Above 50: severe to very severe osteoarthritis secondary to hip dysplasia."

If the scores of the two hips are markedly different, the worse of the two hips should be considered to be more representative of the dog’s hip status, and doubling that single hip score will give a more realistic overall score for the purposes of selection for breeding. For example, a dog with a score of 12:3 should be considered to have a hip status similar to other dogs with a total score in the mid-20s.

Mot slutten av artikkelen finner man snittet for de ulike hunderasene i Storbritannia.

Nederest på siden til OFA for HD står det en sammenligningstabell
