27, VAGINAL OVARIOTOMY IN THE COW. 



Objects. Increasing the fat or milk-producing qnalities 

 and the cnre of nymphomania. 



Instruments. Colin's .scalpel, vaginal dilator, Mile.s' 

 spaying shears. 



Technic. Confine the cow in tlie standing position in 

 the stocks, secnring the head firmly and passing two boards 

 beneath the abdomen and .sternnm to prevent lying down, 

 and a rope over the middle of the back to prevent arching 

 of the spinal colnmn and straining. 



Wash and disinfect the tail and tlie perinaenm and flush out 

 the vagina with a .5 per cent, solution of carbolic acid or 

 lysol at a temperature of about 100° F. Insert the vaginal 

 dilator with one hand and push the prolongation at the an- 

 terior end into the os uteri. With the other hand elevate 

 the handle of the dilator and depress and push forward the 

 uterus, thus rendering the roof of the vagina tense and push- 

 ing it downward away from the rectum. Carry the scalpel 

 into the vagina with the right hand and resting it in the 

 oval of the dilator make an incision through the roof of the 

 vagina, beginning at a point 8 to 10 cm. posterior to the 

 OS uteri and extending backward on the median line for a 

 distance of 2 or 3 cm. Be careful to make the incision en- 

 tirely through the mucosa, muscle and peritoneum at the 

 first cut, .since any failure to complete the incision tends to 

 cause the peritoneum to separate from the muscular coat 

 and form a pocket between tiiem, while the peritoneum be- 

 ing very elastic renders it difficult to complete the incision. 

 Introduce two fingers through the incision, and reaching 

 over the side of the vagina to the right or the left, the right 

 or left ovary respectively is recognized lying immediately 

 against the vagina .somewhat below it, just at the anterior 

 border of the pubis, in a mass con.sisting of the cord-like 

 Fallopian tube and the fimbrise of its pavilion. The ovary
