THE INFLUENCE OF FOOD UPON THE COMPOSITION OF COW’S 
. MILK. 
Practical dairymen have quite generally held to the belief 
that the ‘‘ quality’ of milk, meaning by quality the percent- 
age of fat, is largely influenced by the kind of food eaten by 
the cow. Many practical feeders hold that by feeding, for 
example, considerable quantities of cotton seed meal, or by 
turning the cows on to a field of clover, they can produce not 
only larger quantities of milk, but larger quantities of cream 
and butter. How the milk changes with change of food isa 
matter about which the opinions of such feeders are less clearly
