166 TYPES AND MARKET CLASSES OF LIVE STOCK 



Purchase Exposition, the best Jersey returned twenty-six times 

 the profit returned by the poorest Shorthorn. In both tests 

 it will be observed that in the majority of instances the best 

 cow of a breed returned twice as much profit as the poorest cow 

 of the same breed. 



At the Louisiana-Purchase Exposition, a Holstein cow was 

 the leader in total production of milk and butter-fat, and a Jersey 

 led in economy of production. The following facts from the 

 complete, detailed reports are of much value in showing the 

 possibilities for profit from well-bred dairy cows of real dairy 

 type. Although varying considerably in the quantity and 

 quality of milk produced, it will be observed that they were 

 nearly equal from the standpoint of net profits:

The highest records in milk and butter-fat production are 

 useful in showing the possibilities in the breeding, feeding, and 

 management of dairy cattle. Sometimes these records are made 

 regardless of economy in production, no expense being spared 

 to give the cow every opportunity to make a high record; some- 

 times they have been secured at the expense of the cow's future 

 usefulness, her constitution being undermined and her digestion 

 permanently deranged by the forcing methods that are prac- 

 ticed. Hence the value of such records is sometimes over- 

 estimated. 



Following are the leading records of the various dairy 

 breeds, the world's records over all breeds being indicated by 

 an asterisk (*).
