Corn and Clover Ensilages, 1901-2. 



141 



Compai'ing these ensilages, we notice first that in percentage of dry matter three of 

 them, 'A', 'B', and 'D', are almost identical. Ensilage 'C contains about 1-5 per 

 cent more moisture than the others. 



In ci'ude protein, as well as albuminoids, ensilage ' B ', consisting of two-thirds 

 clover, is the richest, as might be expected.* 



The relation of protein to proportion of clover does not, however, hold good in ensil- 

 age ' C ', consisting of two-thirds corn, probably due to imperfect mixing of the material 

 when being put into the silo, which would naturally result in the sample for analysis not 

 being strictly representative of such a mixture. The general effect of the clover in 

 increasing the protein-content is, however, well illustrated, especially on comparing these 

 results with those for corn ensilage, as already given in the series. It seems quite possi- 

 ble by this means to obtain an ensilage containing from one-half to three-fourths more of 

 the flesh-forming constituents than is obtainable from corn only. This is, of course, a 

 very important matter, for it points to the fact that the use of such ensilages would 

 allow of a reduction in the grain part of the ration. 



The addition of the small proportion of sunflower heads, in ensilage ' A ', does not 

 appear to have afTected in any marked degree the composition of the ensilage. They 

 were expected to increase the percentage of fat. 



The table of data gives the composition of the fresh material and of the dry matter, 

 the latter results allowing a closer comparison to be made as to the changes brought 

 about by varying the proportions of corn and clover.** 



BROME GRASS. 



The excellent feeding qualities of the Awnless Brome Grass {Bromus inermis) have 

 been set forth in previous reports of this division (see reports. Experimental Farms 

 1897, p. 146; 1898, p. 14G), the data obtained in the Farm 



laboratories having shown 



*The 'crude protein' includes the albuminoids or true flesh-formers and the non-albuminoids, the 

 latter consisting of amides and other comixiunds of much less feeding value than the albuminoids. 



**The various constituents of fodders have been discussed and their functions in the animal economy 

 explained in several of the past reports of the chemical division (see, for instance, report for 1900, p. 166-7).
