fed. Our object is to feed a ration that will not pro¬ 
duce too much fat but will cause the cow to produce 
a large amount of milk. 
The amount of concentrates fed may be governed 
to some extent by the amount of milk given by the 
cow. It has been estimated that a cow should be fed 
one pound of grain mixture for every four pints of milk 
produced. Thus, if a cow gives four gallons of milk 
each day, she needs the equivalent of eight pounds of 
grain. Some feeders have taken the butter production

of a cow as the method of determining how much to feed. 
If the cow furnishes one pound of butterfat each day, 
she should have six pounds of concentrated feed. An 
important factor in feeding a dairy cow is that she re¬ 
quires a certain amount of nutrition to support her 
body. Additional feed is needed for the production of 
milk. 
Water and Salt are too often overlooked in caring 
for the cow. If a good supply of running water is not 
available, fresh water should be supplied in a tank or 
trough so that the cows may drink whenever they will.
