232 EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



In the report of this Division for 1908, we give the analysis of a sample of ' frozen 

 oats/ the feeding value of which was distinctly inferior to those now reported on. No 

 doubt the stage of development of the grain when caught by the frost would determine 

 very largely its quality. 



Distillery Grains, Laboratory No. 11161^. — Dried distillery grains are a concen- 

 trate of high feeding value and have been used to advantage, more especially in milk 

 production. The composition of the ' grains ' will depend somewhat on the nature of 

 the cereals used in the manufacture of the ' spirit,' the protein in the kiln-dried pro- 

 duct varying from 24 to 32 per cent, and the fat between 9 per cent and 12 per cent. 

 This large variation renders it desirable to purchase only on guaranteed analysis. As 

 a class dried distillery grains are richer both in protein and fat than dried brewers' 

 grains and, being both palatable and digestible, constitute one of the best feeds on 

 the market. 



Dried Brewers' Grains, Laboratory No. 13827. — Forwarded by a correspondent at 

 Ste. Anne de Bellevue, Que., and stated to be from Molson's Brewery, Montreal. 



Dried Brewers' Grains, No. 13903. — Sent in by a correspondent at Sherbrooke, 



Que., and stated to be a product of a local brewery. 



Both are of good quality, though No, 13827 is somewhat superior by reason of its 



higher protein-content. 



The average cornjposition of this feed, as given by American authorities, is as 



follows: —

Dried brewers' grains rank high as a concentrated feed, being rich in protein and 

 moderately rich in fat, palatable and fairly digestible. Its use has been chiefly for 

 dairy cows, for which it is considered an excellent and desirable feeding stuff. 



Bean Meal, Laboratory No. 11251. — This is a coarse brown meal with an odour 

 of locust bean. It was obtained through H. M. Fowlds & Son, Toronto, and is stated 

 to be ground from a bean imported from Palestine, and sold at $25.00 per ton. 



This is not a feeding stuff with which there has been much experience in Canada. 

 In European countries bean meals have long occupied an important place among the 

 more nitrogenous concentrates. The present sample would appear to be of fair 

 quality as regards protein and fat, but the very high percentage of ash seems to point 

 to the presence of dirt from sweepings or other source. Bean meal, free from foreign 

 matter, and sound, is a feeding stuff of considerable merit, by reason of its high pro- 

 tein-content. Some bean meals possess a bitter taste that renders them unpalatable 

 to stock; on the other hand, many have a sweet and nutty flavour, and are highly 

 relished. , 



Ground Flax, Laboratory No. 1281^9. — The percentage of protein and oil found 

 are considerably lower than those stated to be present. From the analysis of the seed 

 of a number of varieties in 1910, we obtained an average protein-content of 24-77 

 per cent, oil 37-10 per cent, but 'ground flax' as found on the market would be con- 

 sidered of good quality if it contained 21 to 22 per cent protein and 30 to 33 per cent
