| The salaries are modest. Most are top professors are Arigculture Universities. One is at Auburn. The cost to get a OFA certified OFA opion is very modest and most of the cost goes to documentation. They do work for all animals cattle, sheep and whatever to help breeders. It would be best for a breeder to get both a Penn hip and an OFA reading. However, finding Vets that are certified to do a Penn Hip is not that easy.
Some hips can be on the verge of a rating and the quality of the xray itself can make the difference. I do feel confident that OFA can tell if the socket and ball are excellent in shape and fit. What they can't detect is if in the range of motion that fit remains constant. This Penn Hip can detect.
Nancy,
The difference between OFA excellent and good is the same minor changes. I have never understood why some Americans claimed that Germans bred bad hips until now. I will get some more infromation that will show what OFA rates as good hips, ADRK rates as minor changes, HD+/-. And that an OFA rating of Fair would be the same as slightly positive HD+. The hips are the same only the adjectives are misleading, OFA's. In some European Countrys it is a board of twelve that reads the x-rays. These ratings are established by the FCI.  |
