find by calculation that 100 pounds of flax seed has a feeding value equal to that of 120 

 pounds of oil cake. In other words, if the flax seed, for feeding purposes, is worth $3 

 per 100 pounds, the value of 100 pounds of oil cake would be approximately $2.50. 



COCOA-NUT CAKE. 



This feeding stuff, the residue left from the expression of the cocoa-nut oil, has found 

 much favour among the dairymen of British Columbia. Messrs. Lindsay & Fletcher, 

 Abottsford, B.C., in forwarding a sample furnish tlie following information : — ' This feed 

 is procured by a wholesale dealer in Vancouver from a San Francisco house, and presume 

 that it originally comes from the Hawaiian Islands and islands further south. It is sold 

 F.O.B. at Vancouver for $25 per ton.' They further say : — ' It is now extensively used 

 by dairymen along the Fraser, who value it highly, thinking it imparts a peculiar nutty 

 flavour to the milk and cream. It would be of great service to us here to know how it 

 compares in feeding value with oil cake selling at Vancouver for $30 per ton.' 



The cake as received was of a light red colour, possessing in a certain degree the 

 pleasant odour and sweet taste of cocoa-nut. I should judge it to be a very palatable 

 food. 



Analysis. 



Moisture 5-57 



Protein 22 37

Carbo-hydrates (starch, sugar, <fec.) 29-18

Its high protein content and richness in fat make it a feeding stuff of considerable 

 value. 



To obtain the approximate feeding values of cocoa-nut cake and oil cake, we may 

 compare their ' food units, calculated by multiplying the sum of the protein and fat by 

 2^ and adding the total to the amount of carbo-hydrates. Thus : — 



Protein ,

78-675 

 Carbo-hydrates 29-18 



Food units 107-85 



According to these figures, the oil cake has a feeding value about 25 per cent 

 higher than the cocoa-nut cake. The larger percentage of fat in the cocoa-nut cake, 

 however, would make it specially valuable for furnishing this important element of the 

 ration, and in some measure reduce this difference.
