EXPERIMENTAL FARMS 



4 GEORGE V., A. 19T4 



middlings contain the larger amount. In order to compare at a glance the composi- 

 tion of these by-products, we append the following averages from analyses made in 

 the Farm laboratories. 



Average Composition of Bran, Shorts, Middlings and Feed Flour. 



Individual samples of all these by-products will naturally vary somewhat from 

 these averages, but the above data show the main differences in composition between 

 these feeding stuffs, and allow the farmer, with a knowledge of their market prices, 

 to select those best suited to the requirements of his stock. Bran, for instance, by 

 reason of its bulk, its protein and fat and good supply of ash constituents needed 

 for milk production, has shown itself unexcelled for dairy cows, in feeds, for which 

 the comparatively high fibre-content is not an undesirable feature. On the other 

 hand, middlings are more suitable for young pigs, since these animals cannot 

 digest the larger percentage of fibre in the coarser bran. In briefly referring to 

 the nutritive value of feed flours, this by-product, though rich in protein and low 

 in fibre, does not furnish bone-forming material (ash constituents) in the same 

 proportion as bran and shorts and, as a consequence, cannot be used with success as 

 largely as these feeds, for growing animals. 



r 



Shorts, Laboratory No. 13116 — These were forwarded by the Western Canada Flour 

 Mills, Brandon, Man. The analysis shews them to be of distinctly inferior quality, 

 being low in protein and too high in fibre. The legal requirements for shorts are 

 protein not less than 15 per cent, fat not less than 4 per cent, and fibre not more 

 than 8 per cent. 



Wheat by-product from the manufacture of a "breakfast food, Laboratory No. 

 11077. — This feed is comparable with the best class of shorts, but is somewhat lower 

 in moisture, fat and fibre. It should prove a nutritious feeding stuff of merit and of 

 especial value in the meal mixture where it is desirable to keep down the fibre-content, 

 as in pig feeding. 



Rice Meal, Laboratory No. 1135k- — A finely-ground meal, sound and free from 

 rancidity. Evidently a palatable, nutritious feed. The data indicate that in protein 

 and fat it is somewhat above the average of rice meals imported into the United 

 States. 



Rice Meal, No. 13715. — This meal was purchased in Vancouver, B.C., and used 

 on the Experimental Fawn, Agassiz, B.C., in a pig-feeding trial. Though of satis- 

 factory quality it is not quite equal in protein and fat to the better brands of rice 

 meal on the market. 



Rice meal, when of good quality and free from rancidity, is considered an 

 excellent feed for dairy stock and in pig feeding. It is somewhat variable in com- 

 position, but the protein in samples of average quality is about 12 per cent, fat 13-0 

 per cent, and fibre not more than 6-0 per cent.
