DIGESTIBILITY OF COSSETTES.

constituents, which fact in itself explains the decrease in their 

 percentage. As for the albuminoids, they undergo no change 

 as regards their quantity, but their quality slightly diminishes, 

 as is the case with all other substances contained in fodders in 

 general. A cubic metre of the dried residuum weighs 300 kilos. 

 It occupies, consequently, one-half the volume of either the 

 fresh or the siloed cossettes. 



Morgen, in 1888, published a series of investigations on the 

 digestibility of the nitrogenous substances contained in fresh, 

 soured and dried cossettes, which demonstrated that the assimil- 

 ability of their constituents was about the same for each form of 

 cossette. From the data he then obtained he concluded that 

 the albuminoids of siloed cossettes could not be considered less 

 digestible than those of the fresh or dried residuum. They ap- 

 peared, on the contrary, to be possessed of considerable advan- 

 tages in this respect, which led to the conclusion that if there is 

 a loss of albuminoids in a silo, the value of soured cossettes as 

 a forage was not lessened; on the contrary, their digestibility 

 had increased. These experiments led to the following results:

The difference in the analysis, between the soured cossettes 

 and the other two products, appears to be caused by the excess 

 of nitrogenous substances that are not necessarily albuminoids 

 and which are indicated as raw protein. Morgen declares that 

 these data are entirely too favorable to the soured cossettes. He 

 finds that these results are in contradiction of what has as yet 

 been obtained in practice and asserts that this is due mainly to 

 the fact that the dried, fresh and soured cossettes, when exam-
