"The lUifi'alo gluten feed proves to be quite digestible. The fat has approxi- 

 mately the same degree of digestibility as iu corn meal, while the protein apjiears 

 even more digestible. The cellulose and extract matter, however, fall somewhat 

 below those of the corn meal, as would be expected. . . . 



"Corncobs appear fully as digestible as a good quality of English hay, with the 

 exception of the proteiu, of which they contain but a small amount. . . . 



"Winter-wheat bran generally co.sts about $2 per ton m.ore in the retail markets 

 than the spring bran, and it was our object to see if analysis and digestibility 

 warranted this extra price. So far as composition is concerned, the 2 brans .are 

 practically alike. We regret tliat at present positive conclusions can not be drawn 

 from the digestion experiments. In case of the winter- wheat bran, through an 

 unfortunate circumstance, onlj' the results obtained with 1 sheej) can be presented. 

 From the results offered it will he noticed th;.it the protein and extract matter have 

 almo.st identical coeflicients, but the fat appears rather more digestible in the spring 

 bran and the cellulose more digestible in the winter bran. . . . 



"The liner grade of wheat middlings coincides very closely in digestibility with 

 Buflalo gluten feed. The chief difference between the 2 feeds is that the Buffalo 

 gluten feed contains about 4 per cent more protein than the wheat middlings." 



Fourth feeding experiment with steers, J. B. Lindsey (J/o.sm- 

 chuscitfi iStatc ^Sfa. Ept. 1893, pp. 57-76). 



Synopsis.— An experiment with 2 yearling steers to compare different course fodders 

 and soiling r.s. pasturage in summer, and to ascertain the cost of be(>f production. 

 Ilay was found too expensive (at $15) for this purpose. Corn-and-soja-bean 

 silage was satisfactory. The gains were much larger on soiling than on pas- 

 turage. The gains during the whole feeding did not repay the total cost of the 

 food, but allowing for value of manure they a little more than covered the net 

 cost. 



Previous experiments in steer feeding at this station have been 

 reported in UnHetins 40 and 44 of the station and Annual Ee])orts for 

 1891 and 181>2 (E. S. K., 3, p. 162; 4, pp. 67, 478; and 5, p. 198).
