BOARD OF AGRICULTURE. [Pub. Doc. 



various by-products contain from 10 to 45 per cent of pro- 

 tein, as well as from 3 to 20 per cent of fat. Now an 

 excess of fat in a concentrated feed is objectionable, be- 

 cause of its lial^ility to produce inflammation of the udder 

 {ffarget). A feed stuli' containing from 7 to 9 per cent can 

 be fed with a greater degree of safety. An excess of by- 

 products high in fat and protein, t«d to animals, is sure to 

 cause trouble. It is, therefore, very important that the 

 former should have the privilege of knowing the amount of 

 the important constituents contained in the feed he is pur- 

 chasing, and it is only fair play for the manufacturer to 

 state the quality of the goods he offers for sale. 



Again it is a fact that the larger number of these individual 

 brands of feed stuffs vary, from time to time, very seriously in 

 composition. This I desire to prove from actual analyses 

 made at the Massachusetts Experiment Station within the 

 last two years. 



Cottonseed Meal. 



These poor quality meals were quite dark in color and 

 contained the hulls ground with the meat. They were 

 usually offered at from one to two dollars less per ton than 

 prime meal, on the ground that they were a little " ofl' 

 color." The larger part of them were really not worth 

 much over one-half as much as prime meal. 



Gluten Meals. 



The better class of gluten meals has ])een fairly even in 



composition of late. At least one manufacturer prints the 



ojuaranteed composition on the bags. Such an article is of 



extra quality, and the manufacturer is desirous of stating
