970 EXPERIMENT STATION EECORD. 



As shown by the data for frozen straw and chaff, " the frozen straw contains 

 0.63 per cent or about one-seventh more protein tlian the straw from the un- 

 frozen, fully ripened grain ; and, similarly, we lind in the frozen chaff a higher 

 protein content (about 0.39 per cent) than in that from the fully matured 

 wheat. Since the cattle prefer the frozen straw there can be no doubt about 

 its greater palatability. This is partly due to its being less hard and possibly 

 in part to the development of a certain amount of sugar by the frost — a point 

 unfortunately overlooked at the time of analysis, but upon which it is intended 

 to obtain data on some future occasion. It may further be supposed that the 

 digestibility of the immature straw will be somewhat higher than that from the 

 fully ripened grain. . . . 



"As to the comparative feeding value of the straw and chaff from the same 

 crop, the writer is of the opinion that while the former is slightly richer in 

 protein and fat, the latter, by reason of its lower fiber and the fact that it is 

 more readily eaten by stock, is practically, the more valuable fodder." 



Concentrated commercial feeding' stuffs, J. D. Turner (Kentucky 8ta, BuJ. 

 131, pp. ol-107). — The State feeding stuff law is quoted and the results of 

 a number of analyses made under its provisions are reported of the following 

 feeding stuffs : Wheat bran, wheat middlings, wheat shorts, ship stuff", wheat 

 bran and ship stuff", corn bran, corn chops, corn meal, hominy meal and other 

 corn products, cotton-seed meal, linseed meal, mill run, mill feed, mixed and 

 proprietary feeds, gluten feed, and poultry feeds. An undue proportion of 

 corn product was found in a number of samples of wheat products but in 

 general the concentrated feeds were of good quality. 



Commercial feeding stuffs, J. L. Hills, C. H. Jones, and C. Cutler (Ver- 

 moni Sta. Bui. 133, pp. 25-32). — The feeding stuffs examined under the State 

 law included cotton-seed meal, linseed meal, gluten feeds, dried distillers' 

 grains, dried brewers' grains, flax feed, molasses feed, oat feeds, alfalfa prod- 

 ucts, wheat brans, wheat middlings, mixed wheat feeds, red-dog flour, prov- 

 enders, and proprietary feeds. 



The cotton-seed meal, linseed meal, and oat feeds were in accord with the 

 guai-anty. Practically all the whe.-.t brans and other wheat products were 

 of good quality, as were also the provenders. The flax feeds, which are, 

 according to the authors, new in New England, are composed of " broken 

 flaxseed, straw, and many seeds and screenings, some samples be'ng very 

 clean and others quite the reverse." A number of samples of molasses feeds 

 and flax feeds contained large amounts of weed seeds capable of germination, 

 as was shown by special germination tests. 



The analytical data reported cover guarantied feeds only. 



Licensed commercial feeding stuffs, 1907, F. W. Woll and G. A. Olson 

 (Wisconsin Sta. Bui. 157, pp. o-'i, fig. 1). — Analyses are reported of feeding 

 stuffs licensed under the State law and also of flour-mill feeds, of materials 

 not subject to guaranty, and of a number of samples of unlicensed and miscel- 

 laneous feeds. 



The licensed feeds included oil meals, gluten feeds, corn feeds and similar 

 goods, mixed corn and oat feeds, commercial dairy feeds, and animal meal 

 and poultry feeds and similar goods. The feeding stuft"s not subject to license 

 included wheat bran, wheat middlings, and corn and oat mixtures. The un- 

 licensed and .miscellaneous commercial feeds included flax flakes, flax feed, 

 cotton-seed meal, hominy feed, rice bran, dairy feed, special poultry feeds, 

 granulated milk, distillers' grains, sugar feed, gluten cake, mustard cake, 

 mustard-seed bran or feed, flax screenings, wheat screenings, corn screenings, 

 corn meal, oat meal, oat shorts, rye flour, red-dog flour, rye middlings, barley 

 feed, pea hulls, and mixed and proprietary feeds.
