"The loss sustained when corn is cured in the fields and in the silo is about 

 equal. There is a decrease in the digestibility of corn fodder in curing it. 

 There is little difference in the digestibility of field-cured corn and ensilage. 



"The foregoing conclusions lead to the belief that silage is the host form in 

 which the farmer can save his fodder corn; because, first, it is succulent and 

 palatable, and the animals cat it much more readily than field-cured corn; 

 second, the cost of putting corn into the silo is hut slightly greater than that 

 of curing it in the tield ; third, silage is always in a convenient form to feed; 

 and. finally, the loss in the silo is not likely to he as great as the loss in the 

 field, where the wind blows a certain amount of it away. A further loss is 

 sustained in that paid of the fodder fro/en to the ground and any bundles that 

 fall are almost, if not entirely, rendered useless as food.*' 



Brief statements are made regarding the work at the college. 



Investigations on the nutritive value and digestibility of cotton-seed 

 meal containing an abundance of hull and dried yeast residue, F. HONCAMP, 

 If. Popp, and J. Voi. hard {Landw. Vers, slat., C.l {1905), No. 8-4, />/>. 263- 

 214). — In experiments with shoe]) the average coefficients of digestibility for 

 undecorticated cotton-seed meal were: Protein, 73.2 per cent; ether extract, 

 loo per cent; nitrogen-free extract 54.6 per cent, and crude fiber, 23J per 

 cent; and for dried yeast residue: Protein, 86.6 per cent, ether extract. 38.2 

 per cent, and nitrogen-free extract, 81.5 per cent. 



Experiments on the comparative digestibility of meadow hay and oat 

 straw by cattle and sheep, O. Kellnee kt ai.. {Landw. Vers. Stat., 63 (/.''"•"»), 

 No. 3-). pi>. 818-819). — Meadow hay was more thoroughly digested by steers 

 than by sheep, as were also the oat straw constituents, with the exception of 



ether extract. 



The digestibility of different materials used to absorb molasses, with spe- 

 cial reference to the metabolism of mineral matters, T. PFEIFFEB and A. 

 Etnecke {Mitt. Landw. Inst. Brcslau, ■'> il'.xi'n. No. '/. ///<. 547-565). — Since 

 wood meal and peat meal are both used as carriers of molasses in commercial 

 feeding stuffs, the Influence of these materials on the digestibility of rations 

 was tested with sheep. 



It was found that w 1 meal lowered the coefficients of digestibility of the 



ration, no marked difference being observed between raw wood meal and that 

 which had been cooked under pressure. As in earlier work (B. S. K.. 16, 

 p. L'".!!), it was found that peat meal contains only small amounts of digestible 

 nutrients. In connection with the work the balance of income and outgo of 

 sodium and potassium was determined.
