should be examined to see if the " husks " or 

 " hulls " of any foreign seeds are visible, e.g., 

 polygonum, corncockle, or spurrey. 

 (d) When ground linseed cake is made into a gruel 

 with I gallon boiling water to 2 Ibs. meal, 

 it should swell up into a thick jelly. If oil 

 has been extracted with solvents, the meal may 

 not swell up into a jelly at all. 



Decorticated Cotton Cake is bright yellow in colour. 

 It is usually made from American cotton seed, and 

 has the hulls removed before the oil is extracted from 

 the kernel; hence the cake has only traces of "hulls" 

 present, and is called " decorticated " (dehusked) cotton 

 cake. The removal of the black hulls gives the cake 

 the nice yellow colour of the kernel. 



This cake is exceedingly rich in albuminoids (41 per 

 cent). The oil may vary from 7 to 14 per cent., but 

 8 per cent, is the most usual. It is moderately rich 

 in carbohydrates (26 per cent.) and low in fibre (8 

 per cent.). 



Occasionally hard lumps or " knots " are found in 

 the cakes, especially those low in oil, due to the meal 

 collecting into balls while it is being steamed in the 

 kettle ; the subsequent pressure makes them into small 

 hard balls or " knots." Such cakes should be avoided. 

 When the cake is ground into a meal, the so-called 

 " yellow meal " is obtained. 



This cake is far too rich in albuminoids to be fed 

 alone, and should generally be blended with other 

 concentrates which are poor in oil and albuminoids, but 

 exceptionally rich in carbohydrates such as maize, 

 barley meal, etc. It can be used for fattening bullocks 

 up to 4 Ibs. per head per day, as part of the concentrate
