PROFITABLE DAIRYING 



Rule I. Feed as many pounds of grain daily 

 as the cow produces pounds of fat per week with 

 all the hay and silage she will eat. 



Rule II. Feed one pound of grain daily for 

 each three to four pounds of milk which the cow 

 gives daily and all the roughage the cow will 



must be understood that both of these 

 depend upon the kind of grain 

 and roughage to be fed, which 

 must in themselves constitute a 

 good dairy ration and must con- 

 tain the right amounts of protein, 

 carbohydrates, and fat in the right 

 proportions. With oat straw as 

 roughage and corn meal as grain 

 the rules would be valueless, since 

 neither is sufficiently rich in pro- 

 tein. On the other hand, alfalfa 

 hay and bran fed according to 

 the above rules would prove very 

 expensive feeds. To apply the 

 rules successfully the ration must 

 be first compounded and balanced 

 before being fed as directed in the 

 rules. 



A dairyman can easily compute the amount of 

 feed that each cow should receive per day; and 

 also compute the cost of this feed. By formu-
