52 MAINE AGRICULTURAL EXPERIMENT STATION. I916. 



From the data given in the preceding tables and the weight 

 of the animals as given on page 50, the digestible protein and 

 the total digestible nutrients per 1000 pounds live weight are 

 readily computed. In the table that follows these are com- 

 pared with the modified Wolf-Lehman standards for milch 

 cows producing the amount and quality of milk these heifers 

 gave. 



Protein and total digestible nutrients per 1000 pounds live 

 weight in the daily ration used by each animal in the test* 

 compared with the modified Wolf-Lehman standards for 

 cows giving the weight of milk and per cent of butter fait 

 these heifers gave per day.
