Quantities of Roughage and Grain To Feed. 



In this connection the general principles brought out earlier 

 in the discussion should always be kept in mind, namely, that 

 economical feeding demands that the cows be fed to full ca- 

 pacity. To do this and to have the best effect on the individual 

 cow requires a thorough knowledge of feeds and of cows. To 

 give a few practical rules to guide the beginner in obtaining 

 this knowledge is all that has been attempted in this publication. 

 Rules of this nature in reference to the quantities to feed will not 

 be out of place. 



I. — Under most circumstances the cozv should he fed all the 

 roughage that she will eat up clean, adjusting the grain ration to 

 the milk production. Only when the cow tends to become over- 

 fat shoidd the quantity of roughing he restricted. 



2. — A grain mixture should he fed in the proportion of 1 

 pound to each 3 fk'^ts or pounds of milk produced danly by the* 

 cow, except in the case of a cozu producing a floiv of 40 pounds 

 or more, when the ration can he 1 pound to each 3^ or 4 pounds 

 of milk. An even better rule is i pound of grain each day for 

 every pound of butter fat produced during the zmek by the cozv. 



3. — Feed all the cow will respond to in milk production. 

 When she begins to put on flesh, cut dozvn the grain.
