298 Concentrated Feeding-stuffs. [July, 



presence of mustard may be detected by the smell. Cakes 

 resulting from the chemical process of oil extraction will not 

 always form such a jelly. They are usually very poor in oil. 



Linseed cake, like the seed, is highly valued for young or 

 weakly animals, and is commonly regarded as unsurpassable 

 for fattening cattle. 



Although some other foods, or mixtures of foods, may 

 produce as large an increase in fattening cattle, none has the 

 same capacity for imparting "finish" and "touch." The 

 best feeders, therefore, generally finish their cattle on a liberal 

 allowance of linseed cake. Should the supply exceed about 

 4 lb. per head per day, however, the flesh and fat produced 

 are liable to be soft and lacking in agreeable flavour. 

 Similarly, if more than this amount be given to milch cows, 

 the butter-fat tends to become unduly soft and to acquire a 

 linseed-oil flavour. 



Circumstances may arise in which it becomes desirable to 

 use home-grown grain instead of purchasing linseed cake for 

 the fattening of cattle or sheep. The following substances J 

 may be mixed in the proportions indicated and ground in an | 

 ordinary steel grist-mill : — 



8 bushels oats 



4 barley (or maize) 



2 peas 



1 bushel linseed 



If this mixture be given to stock with an equal weight of 

 ground decorticated cotton cake, the whole will approximate 

 in composition to good linseed-cake. 



Cotton Cakes. — Cotton seed, as it is gathered from the 

 plant, is covered by a dense mass of long white cotton fibres. 

 Cotton is removed from the seed by the process of "ginning," 

 and when this is done the cotton seed has either a smooth, 

 dark-brown hull or husk as in Sea Island and Egyptian ) 

 cotton, or is covered by a dense greenish fuzz as in American 

 Uplands cotton, or by a close ashy fuzz or velvet as in most 

 kinds of Indian cotton. In the process of extracting the oil j 

 the kernels may first be removed from the hulls, or the hulls 

 may be ground in along with the kernels. If the hulls are 

 separated from the kernels we get decorticated cotton cake; 

 if the hulls have not been removed we get un decorticated 

 rough, or "English " cotton cake. The latter cake is usualh
