A YEAR IN AGRICULTURE 



Compare the reports of each pupil. Account for differences 

 in selling value and milk yield. 



2. Table of stock foods with percentage of digestible 

 nutrients. 



By using the above table, figure out the nutritive ratio for 

 the rations given for dairy and beef cattle in the above para- 

 graphs. 



Note By referring to tables for all stock foods the nutri- 

 tive ratio for other feeding rations is determined. 



3. Reports on home feeding. Let the pupils report upon 

 the kinds of stock feeds used at home. Give the amounts of 

 grain and roughage fed each cow, and determine whether it 

 is a balanced ration. 



4. Observational study of external parts of the dairy 

 cow. With a cow or a large chart before the class, drill 

 in the naming of the external parts of the cow until they 

 are familiar to every member of the class. 



5. Use of the score-card for dairy cattle. Bring from 

 one to three dairy cows to the schoolyard or let the class go 

 to a dairy herd. Use the score-card recommended by the 

 State Experiment Station in judging each cow, after sev- 

 eral lessons in placing the animals in order of their rank
