Derivation of coefficients of digestibility. 



The digestive work of the two cows was wonderfully uniform, not 

 differing essentially in the digestibility of any constituent of the ration 

 in either period. We are safe, therefore, in taking the average per cent 

 of digestibility in each case. The following table gives the average per 

 cents of digestibility for the various factors in each period:
