1108 EXPERIMENT STATION RECORD. 



"Pure rice bran should contain not less than 10 per cent protein and 6 per cent fat, 

 or more than 20 per cent crude fiber. 



"Pure rice bran is slightly superior in composition to corn meal. 



"Any addition of rice hulls lowers the feeding value of the mixture. 



"Commercial rice bran may contain as low as 4 per cent protein, and as high as 50 

 per cent crude fiber. 



"The mixture of bran, polish, and hulls in the proportions in which they come from 

 the grain will contain about 7.5 percent protein and 28 per cent crude fiber, and has 

 a little over half the value of pure bran. 



" Mixtures of rice bran with rice hulls, or with hulls and polish, should be sold under 

 their true names, and on their own merits, and not under the name and on the 

 merits of a superior article." 



Inspection of feeding- stuffs in 1904, F. W. Morse {New Hampshire Sta. Bui. 

 116, pp. 8). — Under the provisions of the State feeding stuff law analyses were 

 reported of cotton-seed meal, linseed meal, gluten meal and feed, dairy feed, hominy 

 meal and feed, and wheat, oat, and corn and oat feeds. Of the 50 samples examined 

 5 showed marked deficits in protein or fat. 



"Two samples of cotton-seed meal were low in protein; but one of them was 

 exceptionally high in fat, which in a measure offset the deficit. A sample of linseed 

 meal showed a similar deficit in protein, partially made good by an excess of fat. 

 A sample of hominy feed was unreasonably low in both protein and fat, and a 

 sample of beef scraps was low in protein only. One sample of gluten feed unaccom- 

 panied by a guarantee was much lower than the average in protein, but was retailed 

 at as high a price as the others. 



"The prices of the different kinds of feeds should be carefully considered by the 

 purchaser. They are apparently based on the demand for certain classes of goods 

 and are made as high as the market will bear. They frequently are out of propor- 

 tion to the intrinsic value of the material and vary widely in different localities for 

 the same kind of feed." 



Condimental, tonic, and other stock foods, W. Frear {Pennsylvania Sta. Bui. 

 70, ]>}>. 7). — Chemical and microscopical analyses of a number of condimental and 

 tonic stock foods and proprietary feeds are reported. According to the author, 

 "whatever claims may be advanced for the tonic effects of the usually minute 

 quantities of tonic substances in the condimental foods, or for the shell-producing 

 qualities of the lime of the poultry powders, it is clear that well-known materials are 

 used in compounding these proprietary articles, that the farmer can easily make for 

 himself simple tonic mixtures, and that the prices asked for these proprietary 

 preparations are enormously beyond their commercial worth." 



A milk and butter purifier which it was claimed by the makers would remove the 

 taint of silage, garlic, etc., was found to contain saltpeter as the active agent, with 

 some charcoal and common salt. 



Poisoning from feeding- rape-seed cakes, V. Stein ( Ugeskr. Landm., 49 (1904), 

 No. 13, pp. 167-169). — Cases of diarrhea caused by feeding rape-seed meal of South 

 Russian origin to milch cows were traced to the presence of castor bean meal in the 

 shipment. — f. w. woll. 



Concerning the peanut, W. Mooser (Landw. Vers. Stat., 60 (1904), No. 5-6, pp. 

 321-346, Jigs. 2). — The author identified a poisonous alkaloid in peanut cake which, 

 so far as his investigations showed, was always present in this material. He was 

 unable to secure samples of fresh seeds for study, and so it is uncertain whether or 

 not they also contain the alkaloid. Further studies of the alkaloid and related 

 questions are promised. 



Colorado hays and fodders. Digestion experiments, W. P. Headden (Colo- 

 rado Sta. Bid. 93, pp. 44). — The digestibility of corn fodder, saitbush, and hay from 

 alfalfa, timothy, and native grasses was studied in experiments with sheep, an
