MILK AS THE SOLE DIET OP RUMINANTS 515 



peristalsis. There is a possibility therefore that the fits to which 

 the experimental calves were subject may have heen due in 

 some w^ay to excessive salt consumption. 



SUIVOIARY. 



Milk, thoug'h capable of forming the sole diet of young rumi- 

 nants, can not be used, for such purposes with more mature in- 

 dividuals. This is due not to the fact that its nutrients are 

 present in improper quantities or poor in quality but probably 

 to the inability of the animals to properly digest and utilize it 

 unless they are provided with some roughage at the same time
