CHAPTER III. 



CASTRATION OF THE MULE. 



Objects and Indications — Since the mule is a hybrid and value- 

 less for service as a breeding animal it falls to his lot to undergo 

 castration without exception. Without castration — before the 

 age of two years — the mule becomes exceedingly disagreeable and

Age — "Yearlings," never later unless unavoidable. 



Season — Preferably spring. 



Preparatiot — Same as stallion. (See page 14.) 



Restraint — Same as colt. (See pages 36-39.)

Warning — Same as stallion. (See page 23.) 



Sterilization of Instruments and Cleansing Operator's Hands — 

 Same as stallion. (See page 24.)

 Compound U. S! P. in the strength of one tablespoonful to the
