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 off. Be careful not to pull the cord down out of place.
