EXPERIMENTAL FARMS. 



In other words, presuming the digestibility of these products to be equal, one ton 

 of the buckwheat middlings is equal in food value to 1 ton 120 pounds of the "heavy 

 feed." To assign comparative money values, if buckwheat middlings were worth $16 

 per ton, the heavy feed would be worth $14.11 per ton. 



It must not be supposed from the foregoing that the exclusive use of buckwheat 

 bran is recommended ; a mixed grain diet will always be found not only more palatable 

 to the animals, but as resulting in more profitable returns. This investigation, however, 

 shows that weight for weight the buckwheat product is the more nutritious of the 

 two. 



" GROUND PEED " USED FOR CATTLE IN TRANSPORTATION. 



The comparative value of two samples of " ground feed " used for cattle on board 

 ship, examined at the request of the Department of Marine and Fisheries, is reported 

 upon as follows : 



General Appearance — Both samples consisted largely of crushed or coarsely ground 

 oats and Indian corn (maize). No. 1 contained a large quantity of the thin chaffy 

 membrane of the maize kernel. No. 2 possessed a very considerable proportion of oat 

 chaff — consisting of the palets and glumes of the seed. Judging from a general, as well 

 as a microscopical examination, sample No. 1 would be considered, on the grounds of 

 apparent richness in composition and mechanical condition, the better of the two feeds. 



Chemical Composition. — The samples were submitted to the usual analysis of feed 

 stuffs, with the following results : — 



ANALYSIS OF GROUND CATTLE FEEDS. 



As already stated, the most valuable constituents of a fodder are the albuminoids 

 (or flesh formers) and the fat ; the least valuable, the fibre. Hence, by reason of the 

 greater percentage of the albuminoids, fat and carbo-hydrates in sample No. 1, and the 

 larger amount of fibrous material in sample No. 2, the former must be considered the 

 more nutritious of the two. 



In order to make a comparison between these feed stuffs, or in other words to assign 

 the relative values, it may be assumed as in the preceding chapter, that the feeding 

 values of albuminoids, fat and carbo-hydrates are in the following proportion: — 2-5: 2-5 : 1.
