632 ANNUAL REPORT OF THE Off. Doc. 



IV. Wheat ofial of various sorts, H. O. Dairy Feed and Sucrene 

 Dairy Feed, 14 to 20 per cent, of protein; expenditure per unit of 

 protein, $1.U2 to §1.90. 



V. Corn meal, corn bran and similar corn by-products, rye chop, 

 oats chop and certain mixed cereal feeds, about 9 to 13 per cent, pro- 

 tein; expenditure per unit of protein, $1.10 to |2.53. 



VI. Corn-and-cob chop, sugar feed, oat hulls and feeding-stuffs 

 largely composed thereof, 4 to 9 per cent, of protein; expenditures 

 per unit of protein, |2.01 to $3.94. 



It is dilficult to see how a farmer already well supplied with starchy 

 foods and abundance of good roughage can afford to buy the foods of 

 class VI, which are not only poorer in protein than the grain foods 

 he already has and are less digestible as a class than corn meal; nor 

 if he needs roughage, how he can afford to pay for line ground mill 

 foods when corn stover of fair quality can be bought for a lower price. 



Class V contains, in addition to good foods diluted with oat hulls, 

 many standard grain foods; they are chiefly valuable as sources of 

 starch, and, where protein is the chief thing sought, are too expensive 

 to buy for general feeding purposes. 



It is believed that while this classification does not take into 

 account all the items which must be considered in estimating the 

 real cost of a single food constituent, it may prove helpful in reaching 

 safe conclusions in many cases. 



COMMERCIAL FEEDING STUFFS IN PENNSYLVANI.V A»< 

 COMPARED WITH THOSE IN NEIGHBORING STATES. 



For several years past, a number of the New England and Middle 

 States have made systematic surveys of the feeding-stuffs markets 

 of their respective territories and published the results; in some 

 States, laws regulating the trade in such commodities, requiring some 

 guaranty of composition and establishing a chemical control, have 

 been enacted. Under such conditions, it would be expected that 

 dealers would more uniformly handle articles of prime quality and 

 fully up to their guaranteed value, than in States where such regula- 

 tions and control are not in force. 



The following comparative table showing the composition of some 

 of the principal commercial feeds as sold in this State and in the New 

 England States where various forms of control are maintained, gives 

 ground for serious reflection on the part of the average buyer 

 of these goods in Peunsylvania. The New England figures are ob- 

 tained from a compilation of the analyses from May, 1898, to January 

 I, 1900. (Conn. Sta., Bulletin 130, p. 8.)
