Animal Castration

same time one of the best methods of restraint is to tie head to gate 

 post and have an assistant draw tail between slats of gate above 

 the animal. (See Fig. 144). The object in using crack above the 

 animal is to prevent lying down. A good strong assistant by trac- 

 tion on tail can hold animal against gate in such manner as to limit 

 movement from side to side and up and down. In this position the 

 flank region is readily available for operation.

Instruments — 1. Hairclippers. (Pig. 145.) 



2. Curved head spaying emasculator. (Pig. 146.) This is by 

 far the most satisfactory instrument yet devised for flank spaying. 

 It is easy to handle, takes up very little space in the incision and 

 abdominal cavity, besides controls hemorrhage perfectly. Two 

 other spaying emasculators (Pigs. 147 and 148) are fairly satis- 

 factory. Especially is Figure 147 a good one. 



3. "Parmer" Miles' hook castrating knife (Fia\ 25), or Jami- 

 son's spajdng knife (Fig. 149). The author prefers the Miles' 

 knife. 



4. Suturing fork. (Fig. 150.) The object of this fork is to 

 hold edges of skin wound while the needle is being thrust through.
