Definition of conformation in English:



  • 1The shape or structure of something, especially an animal.

    ‘the judges run their hands over the dog's body and legs, checking its conformation’
    mass noun ‘we've been looking for stock with good overall conformation’
    • ‘Following this event it takes some time for the channel conformation to relax back to the original structure or conformation.’
    • ‘The animal's conformation can be a factor in how well your pack load or horse saddlebags ride.’
    • ‘The judges then walked down the row checking the conformation of the horses and getting a closer look at each one.’
    • ‘It also improves the carcase conformation and composition, while he also finds the lambs are much cleaner due to the lower worm burden.’
    • ‘At an all-breed dog show, the focus lies in the dog's conformation, or overall appearance and structure.’
    • ‘The best approach for correcting a gait fault is to examine the animal's conformation and foot-flight pattern.’
    • ‘This is because we want to start with the x-ray structure conformation.’
