96 ANBIAL CASTRATION 



One to one-half ounces of chloral hydrate dissolved in 

 a quart of water given as a drench twenty minutes be- 

 fore the operation is begun will serve to diminish sensi- 

 bility very materially. 



Technic. — The tail should be tied to one side and 

 the external perineum thoroughly cleansed with soap 

 and water and the vaginal canal irrigated with a one- 

 half of one per cent solution of lysol in warm water. 

 In cows it is necessary to employ a vaginal speculum 

 or to use other means for tensing the wall, as it does 

 not balloon as in mares. The wall having been tensed, 

 which may be done as described in the chapter on spay- 

 ing mares, the operation is conducted exactly the same 

 as this operation on a mare, the operator remembeiing, 

 however, the difference in the disposition of the uterine 

 cornua, and that the ovaries are suspended in a some- 

 what different manner than in the mare ; yet, by trac- 

 ing out the horns from the body of the uterus, no diffi- 

 culty should be encountered in locating the ovaries. 



After-Care and Results. — No after-care is necessary 

 ordinarily. The animal should be allowed a moderate 

 degree of exercise and given a laxative diet. In ani- 

 mals that are chronic "Bullers, " where there is a sink- 

 ing of the saero-sciatic ligament, a flaccid condition of 

 the vulva and the existence of almost perpetual estrum, 

 it is not reasonable to expect that the removal of a 

 diseased ovary will effect a complete correction of the 

 ailment.
