132 AGRICULTURAL EXPERIMENT STATION. [Jan. 



in connection with one pound of rowen or one-third of one 

 iwund of rowen, ivith all the corn ensilage they would con- 

 sume (2| to 3 pounds). The daily diet of botli lots diftered 

 essentially in regard to the relative proportion of digestible 

 nitrogenous and non-nitrogenous food constituents they con- 

 tained. 



The fodder rations fed to lanil)s 1, 2, 3 were less rich in 

 nitrogenous constituents (1 : 6.50 to 1 : 7.40) than those fed 

 to lambs 4, 5, 6 (1:4.50 to 1:5.00). The subsequent 

 statement contains the average composition of the daily 

 fodder ration (per head) during the succeeding periods. 

 Twenty per cent, of the phosphoric acid, potassium oxide 

 and nitrogen contained in the feed consumed has been 

 allowed as stored up in the increased live weight of the 

 animal, and otherwise lost to the manurial refuse.
