SECTION XVII. 



CLASSES OF COMMERCIAL FEEDS. 



In the previous three sections descriptions of the natural and 

 commercial feeds were discussed; feeds are not always found 

 on our markets unmixed, but in various mixed combinations. 

 There are many manufacturers who use the natural and by- 

 product feeds and mix them in varying proportions, often selling 

 them under elaborate trade names. These manufacturers sell 

 enormous quantities of stock feeds to our feeders. 



We will now take up some of these mixtures. On page 91 

 are the principal feeds that the manufacturers offer to the trade 

 with standards of protein, fat and fiber. A feed to be of stand- 

 ard quality should not exceed the fiber content and it should 

 reach the protein and fat contents. The feed should also be 

 clean, free from fermentation, mold, rancidity and be in good 

 mechanical condition. Some of the data in this table is adapted 

 from Bui. 120, Mass. Exp. Station, and represent averages. 



A Discussion of the Table. — It must be remembered that many 

 of these feeds are not sold under the names given in the above 

 table. The manufacturers of mixed feeds usually employ at- 

 tractive names which do not always reveal the nature of the 

 products which make up the mixtures. Eor example, we may 

 find a cotton-seed feed, or a corn and oat feed, or a wheat 

 admixture, or a molasses feed, or a feed mixture "being offered 

 to the trade as Star Feed, Cracker Feed, Balanced Feed, Patchen 

 Feed, Best Feed, Union Feed, Dixie Feed, etc. The straight 

 feeds as wheat bran, wheat middlings (shorts), corn chops, 

 dried brewers' grains, etc., usually carry names that distinguish 

 their nature. 



So this classification is not used on feeds by the manufacturer, 

 but by the chemist who arranges them according to what they 

 contain in the way of natural and by-products feeds. Some of 

 the feeds in the table will not be taken up because we have al- 

 ready spoken sufficiently of them. 



Cotton-Seed Meal. — In the past few years the manufacturers 

 have not always put out this product in its pure state, but often
