TYPHOID FEVER CASE CARD 355 



The result will be seen to correspond almost precisely with the standard 

 in energy value and dry, digestible protein. 



These results are arrived at by multiplying the number of pounds 

 of each of the food stuffs selected by the percentage of dry matter, 

 digestible protein and therms in one lb., as shown in the table. 



Thus, 20 lbs. of timothy : Timothy contains 86.8 lbs. of dry matter 

 in each 100 lbs. One pound, therefore, contains .868 X 20 = 17.36 of 

 dry matter, and so on with the protein and therms required. 



If this ration did not fulfil the standard requirements, as, for 

 instance, if the gluten were left out or if we wished to substitute one of. 

 the food stuffs by a cheaper one, we would only have to experiment by 

 adding more or less of the other food stuffs, or using another food 

 stuff richer or poorer in food requirements.
