MANAGEMENT OF THE STALLION 
15 
over six years of age, the Stallion Registration Board of Oregon 18 is 
authorized to reject the issuance of license certificates to stallions suffer¬ 
ing from cataract, amaurosis, periodic ophthalmia, laryngeal hemiplegia, 
chorea, bone spavin, bog spavin, ringbone, sidebone, and curb (when ac¬ 
companied by curby formation of the hock). The Board is further em¬ 
powered to disqualify stallions that are unfit for breeding purposes to dis¬ 
qualify stallions that are unfit for breeding purposes arising from diseases 
or deformities. In order that stallions be licensed to stand for public 
service in the state of Colorado, 19 the law provides that the stallion be 
free from such diseases or unsoundnesses as roaring, ringbone, chorea, 
bone spavin, bog spavin, specific ophthalmia, curb (when accompanied 
with curby conformation), or any venereal or other contagious diseases. 
Ridglings and deformed stallions are also barred. In the state of Okla¬ 
homa 20 the stallioners are given the option to apply for license if they 
are to take advantage of the lien, and certificate of soundness is issued 
only when it is desired to advertise the stallion as being sound. The 
stallion is certified to be sound when found free from moon blindness, 
cataract, roaring or whistling, heaves or broken wind, St. Vitus' dance, 
stringhalt, bone spavin, curb (with curby formation of hocks), glanders, 
farcy, urethral gleet, mange, and retention of one or both testicles. The 
law of Minnesota 21 provides for the rejection of stallions applying for 
license when affected with such transmissible diseases or unsoundnesses 
as bone spavin, sidebone, ringbone, curb (when accompanied by curby 
formation of the hock), glanders, farcy, maladie du coit, urethral gleet, 
and mange. But in case that a stallion which has been previously regis¬ 
tered is found diseased the Stallion Registration Board is authorized to 
issue license stating the nature of unsoundness. Under the same law is 
provided the examination of stallions every four years until said individ¬ 
uals have reached the age of ten years when the same will be exempted 
from further inspection. Montana 28 rejects the enrollment of stallions 
possessing diseases or unsoundnesses as cataract, amaurosis, laryngeal 
heiniplegia, chorea, bone spavin, ringbone, sidebone, gladners, farcy, ma¬ 
ladie de coit, urethral gleet, mange, melanosis, and curb (when accom¬ 
panied by curby hock). In South Dakota 22 such diseases or unsound¬ 
nesses as specific ophthalmia, including moon blindness, laryngeal hemi¬ 
plegia, bone spavin, ringbone, glanders, farcy, dourine, urethral gleet, 
mange, bog spavin, or curb (when accompanied by faulty conformation) 
are sufficient to disqualify a stallion so affected for breeding services. 
The Indiana Stallion Enrollment Board 28 provides for the rejection of 
stallions affected with any incurable, infectious, or contagious diseases, 
but transmissible unsoundnesses are passed which, however, should be indi¬ 
cated in the certificate of enrollment. Condition of soundness is required 
in the first certificate and every two years until the stallion is ten years 
old, at which time and afterwards further application for soundness is no 
longer necessary. The following diseases and unsoundnesses are recog¬ 
nized as contagious, infectious, or transmissible: Recurrent ophthalmia, 
cataract, glaucoma, amaurosis, laryngeal hemiplegia, pulmonary emphy¬ 
sema, chorea, stringhalt, glanders, maladie du coit, urethral gleet, mange, 
bog spavin, bone spavin, curb, when associated with curby conformation 
of the hocks, ringbone, sidebone, and navicular disease. One or more of 
the following diseases and defects are deemed sufficient to bar a stallion 
from registration in the state of Idaho: 24 “Hemiplegia, roaring or whist¬ 
ling, chorea, stringhalt, bone spavin, bog spavin, ringbone, thoroughpin, 
enlarged sidebones, urethral gleet, ophthalmia, cribbing and curb (when 
accompanied by curby hock), or any marked, faulty or weak conformation, 
which he is liable to transmit.” The state of Illinois 26 issues license to 
unsound stallions that may be affected with amaurosis, bog spavin, side¬ 
bone, navicular disease, curb, chorea, stringhalt or roaring, provided that 
the unsoundness is indicated on the certificate. However, the stallion
