102 REPORT OF THE CHEMIST OF THE 
FEEDING STANDARDS. 
How much food per day does the different classes of animals 
require? This question is the first asked by the interested reader. 
According to the German standards as given in Armsby’s Manual 
of Cattle Feeding, the quantity of food and the relation between 
the nitrogenous and carbonaceous matter of the foods have been 
pretty well worked out by German investigators. In America 
there is a difference of opinion and the tendency is to lower the 
standards, but the principle involved will stand the test of investi- 
gation while the details will be modified to suit our climate, food 
and animals. Until sufficient data has been accumulated to enable 
American investigators to determine the amount of variation, we 
may safely use the German results as guides. 
In the table following are given the amount of organic matter 
and the digestible albuminoids, carbohydrates and fat required for 
an animal of 1,000 pounds weight.
