THE RAISING OF HEIFERS HAS MANY ADVANTAGES 



The dairyman who keeps individual records, who breeds the 

 cows that show profitable production, to bulls of desirable ancestry, 

 and raises the heifer calves from these cows, is following a system 

 of maintaining his herd that promises the greatest and surest pos- 

 sibilities for herd improvement and increased production. Dairy- 

 men, who are using grade cows exclusively, may apply this method 

 of herd improvement with practically the same assurance of suc- 

 cess as the breeder of pure-bred stock. 



The influence of a sire of known breeding, when mated with 

 cows of profitable production, insures offspring of like character- 

 istics. The practice of raising his own heifers assists the dairy- 

 man in protecting his herd against animals harboring germs of 

 communicable diseases and in guarding the consumer against the 

 dangers of unsafe milk. Aside from yielding a product that may 

 jeopardize the health of the consuming public, unsound cows are 

 also undesirable because they are not in a condition to do justice 

 to their milk-producing ability, causing decreased production. 



SCARCITY AND MARKET VALUE OF SKIM MILK AS A 

 HUMAN FOOD 



The advantages to the dairyman of producing his own cows as 

 above set forth are counteracted, to no small extent, by the difficul- 

 ties of producing them economically under existing conditions. The 

 demand for whole milk is increasing from year to year, both as a 

 product for direct consumption in cities and towns and for the 

 manufacture of condensed milk and cheese. Skim milk is, there- 

 fore, not available on a large number of farms as a feed for raising 

 calves and, although it is considered as- ranking next to whole milk 

 for this purpose, it is impractical to recommend its universal use. 



There are several milk substitutes for calf feeding on the mar- 

 ket, some of which are used very extensively. Doubtless, in many 

 instances, their value is exceedingly high for this purpose. As the 

 demand for whole milk increases, the extensive use of these ma- 

 terials must necessarily follow. A calf meal that will successfully 

 take the place of skim milk as a feed for calves will do much to- 

 ward increasing the cow population of our country and to encour- 

 age the dairymen to develop their herds in accordance with the best 

 principles of breeding, which is a more desirable practice than that 

 of depending upon buying cows from unknown sources.
