PURE BRED DRAFT HORSES 
may be disqualified if afflicted with any contagious or infectious diseases, 
or suffering from periodic opthalmia, bone spavin, ringbone, curb (when 
accompanied by curby conformation). Certificate of soundness is no 
longer necessary in case of stallions 6 years old or over which have suc¬ 
cessfully passed examination for two successive years. 28 Said stallion 
is entitled to a permanent certificate of soundness. However, should this 
stallion constract infectious, contagious, or communicable disease the De¬ 
partment of Agriculture shall have the right to cancel the permanent 
certificate at any time. The North Dakota Stallion Registration Board 27 
rules that no stallion should stand for public service if affected by such 
diseases and unsoundnesses as cataract, amaurosis, laryngeal hemiplegia, 
stringhalt, glander, sidebone, farcy, maladie cu coit, urethral gleet, mange, 
bone spavin, ringbone and curb (when accompanied by curby hock), and 
in like manner the laws of Montana 28 includes the same disqualifying 
factors. Besides, in another clause, Montana statutes provide that “No 
stallion shall stand for public service . . . which is deformed or so 
badly diseased as to be . . . wholly unfit for breeding purposes 
. . . ” The Pennsylvania 20 laws provide for the licensing of stallions 
as are qualified and approved by the veterinarian, said examiner to 
certify on the soundness and conformation of the stallions, and to 
specify such unsoundness and inferior conformation that may be found, 
if any. In another section of the same law, it is stated that “Any stal¬ 
lion . . . the patronage of which, in the opinion of those charged 
with the enforcement of this act, on account of unsoundness, inferior 
type or conformation, may prove a detriment to the horse breeding in¬ 
terests of the state, shall be refused a license, and when license is so re¬ 
fused the said stallion . . . shall not stand for public service in this 
state.” 
The laws of the State of Michigan 30 do not account for any unsound¬ 
nesses or diseases that may bar a stallion of the state for public service, 
but in Sec. 7, the provisions read: “Every stallion brought into this 
state from another state or from a foreign country to be offered for sale 
or for public service shall, before any such sale or use is made, be ex¬ 
amined by the state veterinary board or its regularly appointed repre¬ 
sentative, and certified fby said board or its representative that said 
stallion is free from hereditary, contagious or transmissible unsoundness 
or disease and is of good conformation and breed type and suitable to 
improve the horse stock of the state.” 
Touching on the subject of unsoundness, Section 12 of the Kansas 
stallion law 31 reads: “It shall be optional with owners, keepers, or persons 
in charge of stallions standing for public service whether or not said 
stallions shall be examined for soundness, but no stallion shall be ad¬ 
vertised in any manner either directly or indirectly as a sound stallion 
until a certificate of soundness has been issued for said stallion by the 
Kansas State Live Stock Registry Board, and then said stallion may be 
advertised as sound only during the life of the certificate of soundness. 
This certificate of soundness shall become null and void and not in force 
on December 31 of the year during which it is issued.” The state of 
Missouri 32 make similar provisions on unsoundness. 
The Stud License Law of the state of Kentucky 33 makes no provision 
for any unsoundness or diseases that may disqualify the stallion for 
public service. 
Alexander 34 holds that certain diseases are “heredity or transmissible 
as a predisposition.” These include the following: “eye disease, such as 
periodic ophthalmia or ‘moon blindness’, cataract, amaurosis or ‘glass 
eye’, chorea or ‘St. Vitus’ dance’, constituting ‘crampiness’, or ‘shivering’, 
‘stringhalt’, ‘heaves’ or ‘broken wind’, spavin, ringbone, sidebone, navicular 
disease or ‘grogginess’, melanotic or pigment tumors, and peculiarities of 
conformation rendering animals liable to disease or lameness such as
