Unit 12: Selection & Evaluation Flashcards
2 broad classifications of selection in horses
conformation & pedigree
the physical appearance of a horse due to the pattern of muscle, bone, & other body tissues
conformation
good conformation is the ___ of body parts to form an athletic horse
blending
the bloodlines or ancestors of the horse in question
pedigree
4 steps to approach selection
- soundness & structural deviations
- do a profile inspection from a distance
- view from front (chest width, muscling, structure of front legs/hooves)
- view from rear (muscling of hindquarter & structure of hind legs)
3 main points to check for
- balance
- structural correctness
- muscling
\_\_\_\_ well-set ears \_\_\_\_ bold eyes \_\_\_\_ distance from eye to muzzle \_\_\_\_ nostrils \_\_\_\_ muzzle \_\_\_\_ & \_\_\_\_ characteristics
short, well-set ears large, bold ears short distance from eye to muzzle large nostrils refined muzzle sex & breed characteristics
overshot muzzle
parrot mouthed
undershot muzzle
monkey mouthed
