Studying this table we learn that in a hundred pounds! of corn stover 

 (shock corn with the ears removed) there is 1.7 pounds of portein avail- 

 able for the animal, i. e., digesti/ble, while the carbohydrates equal 82.4 

 pounds, and the ether extract or fatty matter 0.7 pounds. 



Red clover hay is four times as rich in protein as corn stover. We find 

 still more protein in the concentr ates, especially in wheat bran, and oil 

 meal. While corn stover contains a considerable amount of carbohy- 

 rates, corn is much richer in that nutrient; oats are less rich than corn in. 

 carbohydrates, and wheat bran still poorer. In fatty matter or ether ex- 

 tract corn is a great deal richer than corn stover, and oil meaL is still 

 richer than corn. 



REQUIREMENTS CF FARM ANIMALS. 



We readily understand that each farm animal requires a certain 

 amount of food for the support of the body. This subject has' been care- 

 fully studied by investigators, and here i& what they report: 



Table showing the digestible materials required daily by farm 

 animals' per 1000 pounds live weight. 



Digestible Nutrients 



Oarbohy- Ether 

 Protein drates Ext. 



Ox at complete rest in stall 0.7 8.0 0.1 



Fattening cattle (1st period) 2.5 15.0 0.5 



Milch cow (yielding 22 lbs. daily) 2.5 13.01 0.5 



Horse (medium work) 2.0 11.0 0.6 



Remembering that in each case the figures are for 1000 pounds' of 



animal, we learn that an ox of that weight standing quietly in his stall, 



neither gaining nor losing in weight, requires 0.7 pounds, of protein, 8.0 



pounds of carbohydrates, and 0.1 pound of fat or ether extract each 24 



hours to support the body. In other words, this is the amount of food 



material necessary to run the animal machine without acomplishing any
