5. Rumenotomy. 



This operation is fully described in Chapter III., Sec- 

 tion 10. 



6. Castration of Bulls. 



Secure him, either by standing him in a firm stall or 

 throwing him down. This can be easily done by taking a 

 rope about thirty feet long, make a loop in the centre large 

 enough to slip over his head and neck and then tie a knot in 

 it. After the rope is put over his head and fitted on the neck, 

 pass it back between the front legs and bring the ends of it 

 back one on each side and around the outside of the hind 

 legs, and back around the inside just above the hock, then 

 bring them forward on the outside of the front legs through 

 the loops. Have a man on each side to pull on the ropes, 

 which soon throws him down, then tie him up solid. This 

 is the best method known for throwing cattle. 



As soon as you have secured him, take a sharp knife and 

 make a cut along the side of the bag large enough to let the 

 testicle out. Be sure the cut extends to the bottom of the 

 o*ig so that it will form a pocket. As soon as you have let 

 the testicle out, draw it well up and you will notice a white 

 covering attached to the back part. Cut this off close to the 

 testicle with your knife, then you can pull up the testicle and 

 cord free. Pull the testicle and cord well up, and if the bull 

 is over a year old, tie the cord with a strong, fine piece of 

 string about four inches above the testicle, leaving the ends 

 of the string six or eight inches long so that they hang out 

 of the bag and will not heal up in it. Leave this string on 

 until it drops off itself. Cut the testicles off below the string, 

 fill the holes full of salty butter and let him go. 



The reason the string is tied on the cord when the animal 

 is one year old and upwards is because there is danger of 

 him bleeding to death. The operation of castrating a bull 

 standing up is done by securing him in a solid, narrow stall 

 and operating in the same manner as you would if he were 

 lying down. 



7. Castration of Calves. 



Tie him or have some person hold him ; make the cuts 

 in the bag the same as for castrating bulls. When the testicle 

 is out, separate the covering attached to the back part of the 

 testicle with your knife, draw the cord and testicle well up.
