This comparison of the rations fed to the steers shows that the 

 growth varied with the amount of total digestible material consumed. 

 In comparing one ration with another it is evident, however, that the 

 same quantity of nutritive substances was not equalh' effective in 

 all cases. Rations C and E contained no larger amount of nutritive 

 substances than ration B, and yet the former rations uniformh' pro- 

 duced more growth than the latter. Here again we find, as in the 

 experiment with cows, that the most effective rations were the most 

 nitrogenous. 



The results of the Station's two winters' experimental feeding of 

 cows and steers all point to one conclusion, viz : Economy in feed- 

 ing requires that cattle foods should be purchased parth* with refer- 

 ence to the most effective combinations of nutrients, and not wholl}' 

 with reference to the prices.
