SPAYING HEIFERS 107 



the corral; if they have to be moved it must be 

 by good cowmen and very carefully. Confinement 

 in a lot, or corral, I have never tried and should 

 not care to. 



Failures. — In about one percent I fail to get 

 the deep ovary in a reasonable time and let 

 them up. 



I never spay pregnant heifers, stopping at 

 once even if I have removed the left ovary before 

 being aware of the condition. 



Mortality. — When the last bunch I spayed 

 was nearly finished the boys broke the leg of one 

 in throwing her, but I think they were getting 

 tired of bacon. In each of two lots that I spayed, 

 one heifer was found dead about six weeks later, 

 tion. This has been the total loss among up- 

 wards of 1100 heifers spayed during 1910 and 

 1911. I am not a quick operator, about 125 

 heifers a day being my limit, and the antiseptics, 

 peritoneal fluid and sun are very hard on my skin. 

 If my results have been good I attribute it to two 

 things: first, reasonable cleanliness, and second, 

 mever using an instrument except on structures in 

 plain view.
