" The best gains were made with the groniid millet during the fattening 

 period, being 1.7G lbs. per head daily, while the lot fed on corn meal produced 

 2.8 lbs. per head daily during this period. ... 



" Speltz produces a hard fat, about the same as oats ; and as good a quality 

 of meat as corn. . . . 



** Fat made by Black Veronesh millet seed was much softer to the touch than 

 that made by either corn, oats, or speltz. When fed as a fattening ration, this 

 variety of millet seed seems to be more like oats than corn. This is shown 

 by the fact that the lot fed on oats required practically the same quantity 

 of hay per pound of gain as did the lot fed on millet. . . . 



" It required 0.37 of a pound more of ground millet seed than it did ground 

 corn to produce a pound of gain on calves fattened for baby beef. . . . 



" With the exception of the speltz lot, the spayed heifers brought the same 

 price as the steers. . . . 



" Ground oats proved to be a profitable feed for the production of baby beef. 

 I'rom a careful examination of the lots before shipping these steers were 

 nearly as fat as those fed on corn. . . . 



" When the calves were fed in lots on the same kind of grain from birth 

 to maturity those which received the most highly carbonaceous grain produced 

 the largest per cent of dressed meat. . . . 



" In feeding calves for the production of l)aby l)eef the following prices were 

 obtained per bushel for grains used: Corn 47 cts., oats 2G cts., millet 38 cts., 

 and speltz 33 cts."

" Wyoming alfalfa hay runs higher in crude fiber and crude protein than the 

 average. The digestion coefficients of the crude protein is also high. The 

 nutritive ratio of first-cutting alfalfa is 1 : 3.10 ; second cutting for both years, 

 1 : 3.68. Second-cutting alfalfa is apparently a better feed. . . . 



" The native hays of Wyoming are better and more nutritious than timothy 

 grown in the Eastern States." 



Analyses were made of the above-mentioned feeding stuffs, and in view of the 

 fact that alfalfa is more difficult to cure than some other hays in wet seasons 

 detailed studies were also made of the water extract of alfalfa and native hay 

 as it was thought that this material might bear some relation to the difficulty 

 experienced in curing alfalfa hay, particularly in damp weather. The total 

 water extract of alfalfa hay on an average amounted to 27.43 per cent, of which 

 5.93 per cent was ash and 21.50 per cent organic matter. In the case of native 

 hay (western wheat grass) the total water extract was 22.23 per cent, the ash 

 and organic matter being, respectively, 2.58 and 19.65 per cent. In the case of
