190 THE CHEMISTRY OF CATTLE FEEDING 



that the weights of any animals in a similar condition may 

 be applied to them. 



It will be seen that the bodies of adult fat animals contain 

 a larger percentage of fat and a smaller percentage of all other 

 constituents than those of similar animals in the lean or store 

 condition. In fact, it appears as if the process of fattening 

 consisted mainly in the replacement of water by fat. In their 

 memoirs, Lawes and Gilbert express the opinion that, under 

 certain conditions, this may actually occur. When the com- 

 position of the increase is considered, however, it will be seen 

 that the amounts of these constituents are increased, not 

 diminished ; but as the fat is increased by two or three times 

 as much as all the other ingredients together, the relative 

 proportions of the latter are necessarily smaller. 



In order to show what actually happens, the amounts of 

 the contents of the stomachs and intestines were deducted 

 from total percentages given in the tables, and the remainders 

 being the actual constituents of the bodies were calculated 

 to the original live weights of the animals minus these 

 amounts. The results obtained are given in the table, and, 

 for sheep and pigs, also in diagrammatic form (Fig. 13).
