What unsoundnesses in horses may be regeirded as sufficient cause 

 for disqualification of animals by judges in the show ring? 



Some judges disqualify horses which show lameness from any 

 cause whatsoever. But it would seem more logical to disqualify 

 only those in which the lameness is due to structural changes in the 

 limbs, such as ring-bone, navicular bursitis, spavin, curb, splints, 

 quittor, laminitis, tendonitis, shoulder, hip and stifle lameness, etc., 

 and to ignore temporary lameness due to nail- wounds, corns, thrush, 

 etc. 



Other recognized imsoundnesses are: roaring, heaves, periodic 

 ophthalmia, blindness, infectious diseases (glanders, influenza, 

 dourine, etc.), osteoporosis, congenital malformations (cryptorchid- 

 ism, monorchidism, hernis, etc.), chronic hydrocephalus and vicious 

 habits. 



What diseases are hereditary in horses? Mention faulty conforma- 

 tions that predispose to unsoundness in horses. 

 The consensus of opinion would indicate that there are few, if 

 any, hereditary diseases. But there is no doubt about the transmis- 

 sion of defects in conformation. Among the latter should be 

 mentioned : 



Ourby hocks. Base narrow. 



Narrow hocks. Toe wide. 



Knee- sprung. Toe narrow. 



Calf-knees. Narrow, long-coupled back. 



Short, upright pasterns. Small, deep-set eyes. 



Base wide. Narrow forehead. 



These defects predispose to unsoundness.
