40 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
times deceptive, so that it will be a distinct gain when commercial 
cattle foods are branded with their real percentages of protein 
and fat, as presumably will be the case in New York under the 
operation of the new feeding stuff law. 
Moreover, buyers should understand something of the source 
and general nature of the waste products which make up a large 
proportion of our commercial feeding stuffs. The fact that any 
material is an offal from a manufacturing process may or may not 
mean that it is of inferior nutritive value. As an illustration, 
certain parts of the maize kernel which appear in the gluten meals 
and hominy wastes are from the parts of the grain in no way 
inferior, whereas oat hulls are the least valuable part of the seed. 
These facts establish an important distinction between the by- 
products from starch and glucose manufacture and those from the 
manufacture of breakfast foods from oats. For this and similar 
reasons, the ingredients of the various mixed feeding stuffs should 
be clearly stated for the buyer’s benefit, and the provision of our 
new feeding stuff law which, among other things, makes illegal 
the abominable practice of adulterating corn meal with oat hulls, 
without the knowledge of the purchaser, to be sold to him as 
mixed feed from corn and oats, is a step in the direction of en- 
forced honesty in the cattle food trade. 
CLASSIFICATION OF FEEDING STUFFS. 
Cattle foods are often classified in a popular way as “ carbohy- 
drate” and “nitrogenous.” Such a division into two classes, 
based upon the proportions of carbohydrates and protein, is not 
rational. The fact is, there is a quite uniform gradation in the 
percentage of protein in feeding stuffs from cotton-seed meal to 
wheat straw and there seems to be no natural point of separation 
into two groups. It is absurd to place wheat bran with 16 per 
et. of protein in the same group with cotton-seed meal with 45 
per ct. of protein.
