After being assembled, they were either grazed or fed 

 alike for as much as thirty days, to eliminate as far as pos- 

 sible the influence of any differences in previous treatment. 

 This length of time was also employed in becoming familiar 

 with the different animals, with a view to properly dividing 

 them into lots that would represent the same quality, 

 thrift, condition, etc. 



Live Weight. The animals were weighed five days in 

 succession at the beginning of the experiment, and the 'same 

 number of days at the close of the experiment, at the same 

 hour each day, and before being watered. The average of 

 these weighings represents the initial and the final weights, 

 and the difference in these figures is assumed to represent 

 the gain or loss due to the feed or treatment involved. In 

 addition to these initial and final weighings, the animals 

 were weighed at the end of every ten day period through- 

 out the experiment. 



Method of Feeding. As a rule, the animals were fed 

 twice daily at 7 a. m., and at 5 p. m., and were given what- 

 ever amounts of roughage they would consume without un- 

 due waste. ' 



A ton or more of loose hay or stover* was hauled in at 

 a time from the field or stack, stored in a dry place in the 

 feeding shed, and charged up to the lot of animals to which 

 it was to be/ fed. 



The animals were fed in a suitable manger under a dry 

 shed, and were allowed the run of an open lot something 

 like a tenth of an acre in area. 



.The mangers were cleaned each day, and the refuse 

 material was stored in a dry bin provided for that purpose 

 until it was weighed and sampled for water determinations 

 and analysis. 



When the fresh feed was weighed in, a 3000 gram 

 sample was carefully drawn, enclosed in a tight pail and 

 sent immediately to the chemical laboratory for the 

 determination of moisture and subsequent analysis.
