*Main lesions:
**Injury to growth cartilage -> [[Bones - Anatomy & Physiology|premature closure of growth plate]]
**[[Bones Degenerative - Pathology#Osteoporosis (Atrophy)|Osteoporosis]]
**'''Exostoses'''
**[[Musculoskeletal Terminology - Pathology|Osteophyte]] formation in prolonged exposure
*In cats fed bovine liver for prolonged periods
**Rich in vitamin A in grazing animals
**Vertebrae fuse with each other due to bone proliferation - '''cervical spondylosis''' ('''ankylosing exostosis''' of the vertebral column), especially in the neck
*Can also be teratogenic, especially in pigs ([[Cleft Palate|cleft plate]] and abortions)
