COMPUTATION OF RATIONS l/ 



Digestible Energy 

 protein value 

 pounds therms 



Maintenance for 1,250 pounds 0.60 7.00 



Fattening requirement for 2 pounds, gain 7.00 



Total requirement 0.60 14.00 



The digestible protein requirement is not given for i pound 

 gain live weight, so that in computing a ration of this nature it 

 will be necessary to balance the energy value. The digestible 

 protein will then be much higher than is included in the require- 

 ment, but if the energy value is balanced by the employment of 

 the proper amounts of roughage and concentrates the digestible 

 protein will be near enough for good results. 



Suggestion : Require the class to compute a ration for a flock 

 of sheep averaging 135 Ibs. live weight and 16 months of age, 

 from potatoes, gluten feed, corn, clover hay and oat straw, accord- 

 ing to energy values.
