RICE PRODUCTS. 



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



polish. 



Eice Hulls.— nice hulls are the outer coating of the rice grain. They 

 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. 



Rice 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 



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

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

 removes 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- 



Rice Meal. — Rice meal consists of a mixture of rice bran and rice 

 polish with the addition of a small amount 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 

 9.92 per cent ; ash 9.82 per cent. 



Rice Bran, Rice Polish and Rice Meal are the only by-products from 

 the milling of rice which are recognized as feeds. When offered for 

 sale in this State they must correspond to the definitions which have 

 bcei: adopted for them and the guarantees made for them should cor- 

 respond approximately with the average analyses given above. 



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 may be divided into two classes: molasses feeds con- 

 taining grain screenings as the principal ingredient with varying 

 amounts of other materials, and molasses feeds containing alfalfa meal ' 

 as the principal ingredient with varying amounts of other materials. 

 ■ The ingredients which are usually used in these two classes of feeds are 

 as follows: wheat middlings, malt sprouts, corn meal, oat hulls, cotton- 

 seed meal, cotton-seed hulls, dried brewers' grains, barley, cracked corn, 

 dried distillers' grains, gluten feed, linseed meal, rice bran, rice straw. 

 Many brands contain a small amount of salt. 



Grain screenings are derived from the cleaning of grain preparatory 

 to milling and are produced in large quantities in the great milling
