Animal Castration 



Restraint — If a suitable operating stock is available it should 

 be used. In lieu of the stocks a narrow box stall and slings are the 

 next best method of restraint for spaying operation. When nar- 

 row stall and sling are used it becomes necessaiy to confine the 

 hind feet in such a way that the operator is not subjected to the 

 danger of kicks. The simplest method which will answer the pur- 

 pose is illustrated in Figure 127. It consists of the nose twitch 

 applied and held by an assistant; also an 18-foot %-inch cottcm 

 rope and one hobble strap. Loop end of rope around off hind 

 pastern, then pass it through D of near hind, then upwards and 

 forwards between fore legs, over withers and under main rope 

 behind elbow. Another method is the Hippo Lasso. (See Figs. 

 135 and 136.)

 voluntarily lie down, which greatly interferes with the progress
