8 The Bulletin. 



In executing the law the Department has endeavored to be of 

 service to manufacturers, dealers, and consumers, and wishes the 

 cooperation of all, in order that the efficiency of the work may be 

 increased and its scope extended. The Department will not stand in 

 the way of legitimate trade, but intends to enforce vigorously the law 

 and to drive from the State low-grade and adulterated feeds. 



How to Buy Feeds. 



It needs to be constantly borne in mind that concentrated feeds are 

 bought to supply a deficiency of protein in those raised on the farm. 



With all classes of feeds high percentages of protein and fat indi- 

 cate high feeding value. This is well illustrated in cotton-seed meal, 

 linseed meal, soja beans and similar feeds. High percentages of 

 fiber, on the other hand, go with materials having comparatively low 

 feeding value. The farmer, in buying concentrated feeds, should 

 have these facts clearly in mind. The analyses presented in this 

 Bulletin show that where the materials have 5 to 10 or even 12 per 

 cent of protein, there are, as a rule, also large quantities of fiber, 

 which means that the by-product is the coarse, chaffy part of the 

 grains, or else these materials have been grounel with the other prod- 

 ucts. Of two feeds having an equal amount of protein, the one which 

 has the smallest amount of fiber is the more valuable, and the farmer 

 will not go far astray if he values the concentrated feed which he 

 purchases in proportion to its content of protein and fat. Except 

 at extremely low figures it is doubtful if it will pay auy one to pur- 

 chase concentrated feeds containing less than 8 to 10 per cent of pro- 

 tein, and when they go below these figures they should be looked upon 

 with suspicion. 



At present the prevailing prices of .concentrated feeds bear very 

 little relation to their feeding value. 



The same price is frequently paiel for feeds whether they contain 

 42, 28, 20, 15 or 8 per cent, protein. 



Definitions and Descriptions of Products. 



The name commercial feeding stuff, or concentrated commercial 

 feeding stuff, is usually applied to a class of substances which, in a 

 majority of cases, are the by-products of other branches of industry. 

 Some of these articles, as brans, middlings and cotton-seed meal, have 

 been the daily diet of domestic animals for many years. These 

 products are mainly as follows : 



From Wheat. 



Bran. — -This consists of the outer portion of the wheat grain, and. 

 though somewhat ricli in indigestible fiber, is a valuable feed because 

 of its protein nn<l fat contont. Tt is also rifh in ])lio>])h:it('s and
