72 THE STOCKFEEDER'S COMPANION 



fed to all classes of stock up to 6 or 8 Ibs. per head per 

 day as part of the concentrated diet, and supply a bulky 

 food which opens up very rich foods such as decorticated 

 cotton cakes, etc. Sometimes they are made into a 

 mash for dairy cows. Their composition is as follows : 

 Albuminoids, 19 per cent. ; oil, 5 J per cent. ; carbo- 

 hydrates, 45 per cent. ; fibre, 19 per cent. 



Distillery Grains. These are very similar to brewers' 

 grains, except that other cereal grains besides barley 

 may be used, such as wheat, maize, oats, rice, etc., in 

 order to supply the starch. The process of fermentation 

 is not carried on quite so far, hence distillers' grains 

 have a somewhat higher feeding value than brewers' 

 grains. According to Dr Voelcker the oil and albumin- 

 oids may each be as much as 4 per cent, richer, and the 

 carbohydrates and fibre respectively 4 per cent, poorer, 

 than in brewers' grains. 



(/) Oat By-products. 



In the manufacture of oatmeal, the oats are kiln- 

 dried before they are ground. This enables the meal 

 to separate better from the hulls, which are subse- 

 quently screened off. The short silky hairs found on 

 the thin end of the kernel are also separated and 

 collected, giving what is called "oat dust." In this 

 way about 60 to 65 per cent, of the weight of the 

 oats taken appears as oatmeal, and 20 to 25 per cent, 

 as offal. This shrinkage is largely a result of kiln- 

 drying whereby a certain amount of moisture is lost. 

 Probably three-quarters of the offal consists of oat 

 hulls. 



Oatmeal contains 7 to 8 per cent, oil, n to 15 per 

 cent, albuminoids, 60 per cent, carbohydrates, and 3 per
