72 AGRICULTURAL EXPERIMENT STATION. [Jan. 



Division I. consisted of lambs Nos. 1-3 ; its aggregate 

 live weight was 215.75 pounds at the beginning of the 

 experiment. 



Division II. consisted of lambs Nos. 4-6 ; its aggregate 

 live weight at the beginning of the experiment was 212.50 

 pounds. 



2. Cost of Lambs. 



The entire lot was bought at six cents per pound of live 

 weight, and the sum paid for 450.5 pounds of the original 

 weight amounted to $27.03. 



The wool secured before the beginning of the feeding 

 trial, which amounted to 22.25 pounds, was returned at 23 

 cents per pound. The sum realized by that transaction was 

 $5.12. Allowing the deduction of $5.12 on the first cost of 

 the lambs, which was $27.03, it will be found that their 

 actual cost at the beginning of the experiment was but 

 $21.91, or 5.12 cents per pound of live weight. The live 

 weight without the removed wool was 428.25 pounds.

3. Character and Cost of the Feed consumed. 



To secure a normal and uniform condition of the animals 

 selected for a comparative test of different fodder rations, 

 with reference to their influence on the financial results of 

 the operation, nothing but rowen was fed to the entire lot 

 for ten days preceding the experiment (September 4 to 

 September 16). Subsequently a division of animals was 

 made. Three lambs, 1-3, were fed with daily rations 

 richer in digestible nitrogenous food constituents than those 

 fed to the remaining number, 4-6. 



The daily feed of the first division (1-3) contained on an 

 average from 4.5 to 5.5 parts of digestible non-nitrogenous
