Brief Remarks on the Above Eesults. 



The Buffalo gluten feed proves to be quite digestible. The 

 fat has approximately the same degree of digestibility as in 

 corn meal, while the protein appears even more digestible. 

 The cellulose and extract matter, however, fall somewhat 

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



The new and old process linseed meals compare very favor- 

 ably with each other, only slight differences being observed. 



Corn cobs appear fully as digestible as a good quality of 

 English hay, with the exception of the protein, of which they 

 contain but a small amount. 



Dried brewers' grains and wheat bran approach each other 

 very closely in the amount of dry matter digested. The 

 digestibility of the protein in both cases appears practically 

 identical. The fat in the brewers' grains appears rather more 

 digestible than that in the bran, while in case of the extract 

 matter the opposite is the result. 



Winter w^heat bran generally costs about two dollars per 

 ton more in the retail markets than does the spring bran, 

 and it was our object to see if analysis and digestibility war- 

 ranted this extra price. So far as composition is concerned, 

 the two brans are practically alike. We regret that at pres- 

 ent positive conclusions cannot be drawn from the digestion 

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

 unfortunate circumstance only the results obtained with one 

 sheep can be presented. From the results offered it will be 

 noticed that the protein and extract matter have almost iden- 

 tical coefficients, but the fat appears rather more digestible 

 in the spring bran, and the cellulose more digestible in the 

 winter bran. As these two latter ino-redients are of minor 

 importance, however, because of their comparative small 

 absolute percentage when compared with the protein and 

 extract matter, the comparative value of the two brans 

 would not be seriously affected. Therefore the results thus 

 far would indicate no material difference between the two 

 brans. The experiment Avill be repeated, however, at an 

 early date, and as soon as more decisive results are obtained 

 they will be published. 



The finer grade of wheat middlings coincides very closely 

 in digestibility with Buffalo gluten feed. The chief difference 

 between the two feeds is that the Buffalo gluten feed contains 

 about four per cent, more protein than the wheat middlings.
