Animal Castration 



accompanying fallopian tubes are drawn through the incision. In 

 young sows the left tube is now withdrawn from abdominal cavity 

 and followed back to the biflication where the right tube is encoun- 

 tered. The right tube is withdrawn from abdominal cavity and 

 followed until right ovary is located, after which draw the ovary 

 out of abdomen through incision and place both ovaries (P) in 

 emasculator and sever their attachments by closing handles of in- 

 strument. The tubes (Q) are now washed and replaced in the 

 abdominal cavity (see Fig. 171), after which the incision is 

 closed by two interrupted sutures. These sutures should be made 

 with a No. 3 half circle Hageclorn needle and No. 12 braided silk. 

 They should extend through all layers of the abdominal wall, in- 

 cluding skin and peritoneum, or in other words, should be what is 

 known as the "through and through" sutures. (See Fig. 172.) 

 Sponge off wound with antiseptic solution and release the animal.

In sows which have given birth to one or more litters of pigs 

 the fallopian tubes are oftentimes so large that the left one must 

 be replaced in the abdomen before the right one can be withdrawn. 

 In such vent, of course, only one ovary can be removed at a time. 

 However, both ovaries can always be removed through the same 

 flank incision.
