56 PROFITABLE DAIRYING 



American Exposition the five Ayrshire cows 

 ranked second in milk production, yielding 55 

 pounds per cow for each day of the test. 



Dual-purpose breeds. In addition to the above 

 leading dairy herds, there have been developed 

 milking strains of the so-called dual-purpose 

 breeds that give promise in the dairy world. 

 Chief among these are the Brown Swiss, the Eed 

 Polled, and the Milking Shorthorns. It is argued 

 in support of these breeds that their calves will 

 help to supply the market for "baby-beef" and 

 that their carcasses are much more valuable to 

 the butcher than those of the strictly dairy 

 breeds. It is quite probable, however, that, when 

 these breeds have developed striking dairy qual- 

 ities, their forms will also change so as to 

 render them less valuable for meat production.
