DISEASES AND TREATMENT OF THE HORSE 203 
thus has the effect of closing the end of the artery and pre- 
venting the flow of blood. Some operators take off both 
testicles at the same time. There is, however, more danger 
from bleeding in this way, and we recommend that each be 
taken off separately. The colt may be allowed to regain his 
feet as soon as the testicles are severed. We desire to add 
again that it is absolutely necessary to see that the hands 
and instruments are thoroughly cleansed both before and 
after the operation. 
5. Castration by Searing. 
This method is followed in some places, and is performed 
by letting the testicles out and attaching an iron clamp in 
the same manner as a wooden one. Cut the cord off close to 
the clamp. With a hot iron dipped in oil, burn the end of the 
cord and artery ; this sears it and prevents bleeding. Remove 
the iron clamp and operate on the other testicle in the same 
way. The oiling of the hot iron prevents it from sticking to 
the cord and pulling off the scab. 
6. Castration with Ligatures. 
This method is not generally followed in the castration 
of horses, although it is a very good method for that of bulls 
and boars. Operate on the scrotum in the same manner as 
before. Tie a strong piece of twine around the cords to 
prevent bleeding when the cord is cut. Cut just below the 
twine. 
We have operated by all these methods and our experi- 
ence has proven to our satisfaction that the ecraseur method 
is the safest and best. Should the colt be ruptured, the case 
requires special care, fully dealt with under the heading 
"Scrotal Hernia." 
IV. — Treatment After Castration. 
The colt should not be allowed to remain out at night in 
chilly, damp weather or east winds. Keep him in a box stall, 
clean and well bedded. He may be allowed to run in the 
open air in the daytime when the weather is favorable. His 
diet should be entirely of grass. The clamps when used 
should be removed on the second day after the operation. 
This should be done by cutting the string on the front end, 
spreading the clamp well apart in the front and allowing it 
to fall oflF. Be careful not to pull the cord down out of place.
