RICE PRODUCTS. 



The by-products from the milling of rice consists of hulls, bran 

 and polish. 



Bice Hulls. — Rice hulls are the outer coating of the rice grain. 

 Thej are composed principally of fibrous material, with a large 

 amount of mineral matter, and are worthless as a feed. The hulls 

 are found to some extent in rice meal and bran, and when present 

 in any considerable amount are considered as an adulterant. For 

 analyses, see adulterants. 



Bice Bran. — Rice bran is the thin coating of the grain lying next 

 to the hull. 



Average analysis: Protein, 12.10 per cent; fat, 8.80 per cent; 

 fiber, 9.50 per cent; nitrogen-free extract, 49.90 per cent; water, 9.70 

 per cent ; ash, 10.00 per cent.f 



Bice Polish. — After the hulls and bran have been removed the rice 

 grains are polished before being put on the market. This process re- 

 moves the thin coating lying next to the rice grain. It is sold for 

 feed under the name of rice polish. 



Average analysis : Protein, 11.70 per cent ; fat, 7.30 per cent ; fiber, 

 6.30 per cent ; nitrogen-free extract, 58.00 per cent ; water, 10.00 per 

 cent; ash, 6.70 per cent.f 



Bice Meal. — Rice meal usually consists of a mixture of rice bran 

 and polish, frequently with the addition of varying amounts of hulls. 



Average analysis (11 'samples) : Protein, 11.54 per cent ; fat, 11.49 

 per cent; fiber, 9.96 per cent; nitrogen-free extract, 47.77 per cent; 

 water, 9.42 per cent ; ash, 9.82 per cent. 



DRIED BEET PULP. 



Dried Beet Pulp is the by-product from the manufacture of sugar 

 from sugar beets. After the sugar has been extracted from the 

 ground beets the pulp remaining is dried and put on the market as a 

 feed. 



Average analysis (6 samples): Protein, 9.18 per cent; fat, 0.96 

 per cent; fiber, 17.71 per cent; nitrogen-free extract, 60.24 per cent; 

 water, 8.29 per cent; ash, 3.62 per cent. 



MOLASSES FEEDS. 



Molasses feeds consist principally of mill by-products mixed with 

 molasses. These feeds vary a great deal in the ingredients of which 

 they are composed, many of them being composed of nutritious in- 

 gredients and of good quality, while others contain only low-grade 

 materials the identity of which is covered up by molasses. The in- 

 gredients found in the feeds examined are as follows : Mill screenings 

 (frequently containing considerable amount of weed seed), wheat 

 middlings, malt sprouts, corn meal, oat hulls, cotton-seed meal, dried 

 brewers' grains, barley, barley hulls, cracked corn, dried distillers'
