SELECTION AND IMPROVEMENT OF DAIRY CATTLE 41 



difference between breeds. The advantages may be enu- 

 me -ated as follows : 



J . May save expense in buykig males for breeding, and 

 maKe it possible to make more use of a bull that is found to 

 sin especially valuable animals. 



L'. It is a great advantage in selling stock, since buyers are 

 atl racted by large numbers of the same breed in one locality. 



:;. May save expense in official testing of registered cows 

 for advanced registration. 



':. Makes possible a local breed organization and creates 

 grc ater interest in good stock and proper management. 



if the pastures are steep and rocky, the more active breeds 

 arc likely to be most successful. Where pastures are luxu- 

 riant and where large quantities or roughage are used, the 

 larger breeds are more at home. 



Between similar breeds the preference of the breeder 

 mtiy decide the choice. For example, if location and market 

 would suggest the Jersey or the Guernsey as the most 

 suitable, the choice between the two might be easily deter- 

 mined by preference. If the dairy farmer expects to sell 

 milk for market, wholesale or retail, his choice would hardly 

 fall on the Channel Island breeds, unless the market is the 

 exceptional one that will pay enough more for rich milk to 

 justify its production. For milk production the Holstein, 

 Ayrshire, or Brown Swiss would be the natural choice. On 

 the other hand, if the location is such that cream is to be 

 sold, then the Jersey and Guernsey breeds would come in 

 for strong consideration on account of their well-known 

 economical use of feed for the production of butter-fat. 

 Under these conditions the probable value of skim-milk 

 for pigs and for calf feeding is still another consideration 

 and in some cases is sufficient to cause the choice to fall
