ANUrAL CASTRATION 



Wariinig — Before l)egimiiiig' to operate alwa.ys carefully examine the 

 animal for inguinal and scrotal hernia (rupture), abnormalities in devel- 

 opment, and diseases of tlie scrotum, testicle and cord. It is also well to 

 look out f()r constitutional diseases which would have a tendency to en- 

 danger the life of the animal or interfere with convalescence. Never cas- 

 trate an animal if it is affected with strangles, influenza, pleurisy, pneumo- 

 nia, bronchitis, catarrhal fever, or pnrjDura hemorrhagica. Be careful in 

 casting and tying and aliove all satisfy yourself tliat the testicles are ac- 

 tually in the scrotum. 



Sterilization of Instritmeiits — If good results are to be attained all in- 

 struments should be sterilized by boiling for fifteen to twenty minutes; 

 after boiling, immerse them in a porcelain bowl or granite pan containing 

 one tablespoonful of either Lysol or Liquor Cresolis Compositus (U. S. P.)

to each quart of water. In the absence of the above, carbolic acid in two 

 per cent solution is permissible. Where there are several animals to be 

 o])erated upon it is not practicable nor is it necessary or desirable to boil 

 tlie in.struments between operations. However, they should be washed and 

 placed back in the antiseptic solution.
