THE STOCKFEEDER'S COMPANION 



In order to understand the practical side of feeding, 

 it will be instructive and helpful to know something of 

 the chemical composition of the animal body. Here one 

 cannot do better than refer to the valuable work done 

 by Lawes and Gilbert at Rothamsted Research Station 

 (Hertfordshire, England), where the bodies of cattle, 

 sheep, and pigs at different ages and varying stages of 

 fatness were carefully analysed, and the following im- 

 portant data obtained. 



The figures for the entire body of these farm 

 animals are based on the fasted live weight, after the 

 contents found in the stomach and intestines (varying 

 from 3 to 9 per cent, of the weight of the animal) have 

 been deducted. The latter precaution is very necessary 

 before any comparisons can be made between the entire 

 body and the carcass.
