PROGRESSIVE BEEF CATTLE RAISING 



Three or four decades after this the foundations of the 

 Aberdeen-Angus were securely laid by Hugh Watson in 

 the north of Scotland, while numerous breeders were 

 busily evolving the Galloway. During the eighties of 

 the last century the problem of horn bruises in shipping 

 cattle became so important in America that the Polled 

 Shorthorn and Polled Hereford arose. Each of these 

 breeds was developed to meet a special economic need, 

 and the animals chosen as founders of the breed were 

 arbitrarily selected on the basis of their transmitting the 

 desired characters to their descendants. 



The success of pure breeds of cattle 

 The Value of in meeting the needs for which they 

 the Purebred have been developed is evident by a 

 comparison of the average sale values 

 of purebred breeding stock with market stock of approx- 

 imately equal quality. This latter class may be found in 

 the native steers marketed at Chicago each year and the 

 difference in value between them and purebred cattle may 

 be interpreted as the value of the reproductive function 

 plus the pure breeding. The data are as follows :
