ANIMALS 



Nine different steers have been used, varying in age from 1 1 months 

 to approximately 60 months at the beginning of the several experiments.' 

 They were either full bloods or high grades of recognized beef breeds, 

 with one exception, steer B, which was distinctly of the dairy type and 

 of mixed breeding (scrub), Jersey blood apparently predominating. All 

 were docile animals and were thoroughly accustomed to the necessary 

 handling, to wearing the apparatus for the collection of excreta, and to 

 their surroundings in the digestion stall and the calorimeter. Further 

 particulars concerning them are contained in Table II.

 ing periods.
