Dividing by 21.95 =: 1 : 5 , the nutritive 



ratio. 



Note. — The nutritive ratio of the above ration, based on the equal 

 weight", of grain mixture and mash is 1 : 4.3. As in actual practice 

 the hen consumes only half as much mash as grain mixture, we must 

 divide the protein and carbohydrate of the mash by two and add the 

 quotients to the corresponding weights in the grain mixture. The re- 

 sulting weights will enable us to obtain the nutritive ratio of the actual 

 nutrients consumed by the hen. 



Ground oats can be used instead of oat meal, but add 9 per cent to 

 allow for crude fiber.
