MINOR SURGICAL OPERATIONS 293 



Young lambs are held by an assistant and may be docked 

 at the same time. 



Large rams may be "hog tied" like the boar on the ground, 

 except that the lower hind leg should be included in the tie. 

 The upper may be either held forward or included in the tie. 

 Older lambs and small rams may be held on the rump, belly up 

 somewhat as for shearing, the assistant holding both hind legs. 



Season. — Good weather is desirable especially for lambs—

usually spring or fall. Dust should be avoided; therefore a 

 quiet day is preferred. 



Operation. — The scrotum incisions should be parallel to and 

 reasonably near the median line or "seam." See Figure 94. 

 This should be done with a free sweeping cut and few move- 

 ments. Except in case of a ruptured animal, young boar, for 

 instance, the incision should go through the thin transparent 

 sac * around the testicle. The incision should be reasonably 

 long and extend to the lowest point where pus could otherwise 

 collect. 



The testicle is removed in various ways, the choice depending 

 principally on the danger of hemorrhage. For lambs under 

 about three weeks, the cord is simply pulled in two after free- 

 ing the testicle. For pigs, calves and older lambs, the blood 

 vessels may be divided by moderate pulling and slow scraping
