SELECTION AND IMPROVEMENT OF DAIRY CATTLE 53 



An animal lacking in barrel cannot use sufficient feed to 

 ma ke her a large producer. The age of the animal has some 

 influence upon the size of the barrel. The apparent capacity 

 is also influenced to some extent by the ration fed. Bulky 

 feeds, such as hay and silage, when fed in large quantities 

 gh e this effect. In considering the barrel development of a 

 cow the depth as viewed from the side should be observed, 

 th<>n the width as viewed from behind. Some animals show

 capacity. In short a dairy cow should show great vigor, 

 great capacity to use food, and should have a strong de- 

 velopment of the milk-secreting organs, indicating that she 

 is likely to use the food for milk production. 



44. The Score Card. The score cards adopted by the vari- 

 ous breed associations are shown on pages 290 to 296. These 

 are designed to set forth the desirable characteristics of the 

 breed and may be studied as a means of becoming familiar 

 with breed types. The preceding discussion of the dairy 

 type is general and applies to all breeds. It is based wholly 

 upon the indications of milk production and does not take
