PROTEIN. REQUIREMENTS. 123 
Henry’s Feeds and Feeding, Article 182—and adding the 
product to the sum of carbohydrates and protein, showing 
total nutriment consumed daily per 1000 pounds live weight, 
also multiplying the butter fat by 2.5 and adding the prod- 
uct to the solids not fat for total product daily, and giving 
the net nutriment required to a pound of total product.

By this it is clearly shown that the three groups yielded 
dairy products in proportion to the nutriment available for 
product, and not according to protein supply, and that the 
amount of nutriment required to a pound of total product 
depended upon the ratio of butter fat to milk solids not fat. 
The following table gives the daily average ration fed 
during the three winters, reduced to a basis of 1000 pounds 
live weight; total nutrients and the Wolff standard:

Comparing the rations fed during the winters 1894-5, 
1895-6 and 1901—2 with the Wolff Standard we find little 
difference so far as total digestible matter is concerned; the 
rations exceeding it by about .4 of a pound. They contain 
about 50 per cent more ether extract. The carbohydrates 
also exceed those given in the standard, except for the win-
