NUTRIENTS DIGESTED DURING THE METABOLISM TEvST 



The apparent coefficients of digestibility of the nutrients and the 

 amounts of nutrients apparently digested during the metabolism test 

 were calculated from the weights and the analyses of the feeds, orts, and 

 feces. The weights and composition of the feces are given in Tables IV 

 and V, respectively. The apparent coefficients of digestibility of the 

 nutrients are given in Table VI. The quantity of dry matter, protein, 

 nonprotein, ether extract, carbohydrates, ash, phosphorus, and nitrogen 

 apparently digested daily by each lamb during the 1 2 days of the metab- 

 olism test, together with the calculated values for the metabolizable 

 energy, or fuel values expressed in Calories, are given in Table VII.
