Some knowledge of the composition of the bodies of 

 hogs is of value to the feeder in aiding him to judge of 

 characteristic food requirements. The most extended 

 research on this line was made by Lawes and Gilbert at 

 the Rothamsted (England) experiment station. The re-

 the determinations as to the composition of animals 

 were included those of the collective carcass parts, col-

 (lean) pig- and a fat pig, which follow:
