Flour Middlings. — Average analysis: Protein 17.54 per cent; fat 

 6.14 per cent; fiber 4.10 per cent; nitrogen-free extract 59.30 per cent; 

 water 8.82 per cent; ash 4.10 per cent. 



Red Dog Middlings. — Average analysis (13 samples) : Protein 17.15 

 per cent ; fat 5.41 per cent ; fiber 2.34 per cent ; nitrogen-free extract 

 61.82 per cent; water 9.68 per cent; ash 3.60 per cent. 



Sliipsiitjj'. — TLf term shipstuff should be applied only to mixtures of 

 wheat products. It is generally applied to mixtures of bran and mid- 

 dlings and reground bran. It is frequently misused and applied to mix- 

 tures of wheat products and corn chops or corn bran, and sometimes to a 

 mixture of wheat, corn and oat products. Such products should be 

 branded Feed or Mixed Feed, and not Shipstuff. 



The following analysis is the average of forty-three samples of pure 

 wheat shipstuff: Protein 15.98 per cent; fat 4.87 per cent; fiber 5.67 

 per cent; nitrogen-free extract 60.03 per cent; water 8.98 per cent; ash 

 4.47 per cent. 



RYE PRODUCTS. 



The by-products from the milling of rye are very similar to those 

 from wheat. 



Bran. — Average analysis: Protein 14.70 per cent; fat 2.80 per cent; 

 fiber 3.50 per cent; nitrogen-free extract 63.80 per cent; water 11.60 per 

 cent; ash 3.60 per cent.f 



Middlings. — Average analysis (7 samples): Protein 16.07 per cent; 

 fat 3.79 per cent; fiber 4.41 per cent; nitrogen-free extract 60.95 per 

 cent; water 10.50 per cent; ash 4.28 per cent. 



CORN PRODUCTS. 



Bran. — This is the outer coating of the corn grain. It has a low 

 feeding value and is used to some extent as an adulterant for wheat 

 products. Its chief use is in mixed feeds and corn chops. Average 

 analysis (2 samples): Protein 7.00 per cent; fat 2.82 per cent; fiber 

 11.89 per cent; nitrogen-free extract 65.44 per cent; water 11.08 per 

 cent; ash 1.77 per cent. 



Corn Chops. — This product is quite variable in the ingredients of 

 which it is composed, sometimes being composed of the entire grain and 

 ground rather coarse, while in other cases it is composed of parts of the 

 grain with the addition of reground bran, and cob meal. The following 

 analysis is the average of seven samples of corn products : Protein 8.78 

 per cent; fat 5.04 per cent; fiber 5.22 per cent; nitrogen-free extract 

 71.50 per cent; water 7.68 per cent; ash 1.78 per cent. Other names 

 used for this class of products are Hominy Feed and Hominy Chops. 



Corn and Coh Meal. — Corn, together with the cob which bears it, are 

 frequently ground together to form what is known as corn and cob meal. 

 In such cases the cobs are not considered an adulterant, provided the 

 amount of cob does not exceed that which would normally be present 

 with the grain, i. e., 14 pounds of cobs to 56 pounds of grain. Average 

 analysis: Protein 8.50 per cent; fat 3.50 per cent; fiber 6.60 per cent; 

 nitrogen-free extract 64.80 per cent; water 15.10 per cent; ash 1.50 per 

 cent.f
