NUTRITION OF FARM ANIMALS 



Respiration experiments by Soxhlet 1 on three young calves 

 included determinations of the gain or loss of ash, while the 

 live weights of the animals are also recorded. The feed being 

 exclusively milk, the variations in the contents of the digestive 

 tract were probably slight and a computation of the composition 

 of the increase based upon the live weights seems justified. 



The results of both the slaughter and respiration experiments 

 are contained in the following table, the energy content being 

 computed from the fat and protein.
