Composition and Nutritive Value of Cotton-cake. 



In the following Table I have incorporated the results obtained 

 in the analysis of seven samples of decorticated cotton-cake : 



COMPOSITION OF DECOKTICATED COTTON-CAKE (THIN CAKE). 



These analytical results suggest the following observations : 



1. The proportion of oil in all the samples analysed is higher 

 than in the best linseed-cake. In the best linseed-cake the per- 

 centage of oil rarely amounts to 12 per cent., and 10 per cent, 

 may be taken as a fair average. As a direct supplier of fat, 

 cotton-cake therefore is superior to linseed-cake. 



2. The amount of oil in samples sold under the same name 

 is subject to considerable variations. In the oiliest cake, No. 2, 

 there is 19'19 per cent., and in No. 7 only 13'50 per cent, of oil. 

 The greatest difference in these cakes in this respect thus amounts 

 to about 5J per cent. 



3. Decorticated cotton-cake contains a very high and much 

 larger percentage of flesh-forming matters "than linseed-cake. 

 This circumstance suggests that cotton-cake may probably be 

 given with great advantage to young stock and to dairy cows. 

 As by far the largest proportion of nitrogen of food is not 

 assimilated in the system, but passes away with the excrements 

 of animals, the dung produced by stock fed upon cotton-cake 

 will be found particularly valuable. 



4. In comparison with linseed-cake there is much less mucilage 

 and other respiratory matter in cotton-cake. This deficiency,
