I06 FEEDING FARM ANIMALS 



The second trial corresponds very nearly to the 

 standard. The protein does this with exactness, 

 while the energy value is just slightly under what 

 the standard calls for. This is of small importance 

 since, as explained heretofore, it is not expected that 

 the rations shall be made to meet the standards with 

 mathematical accuracy. The aim should be to ap- 

 proximate them. From this we learn that, accord- 

 ing to the Armsby standard, a satisfactory ration for 

 milk cows weighing 1,000 pounds and yielding 25 

 pounds of milk daily may consist of 5 pounds of corn 

 stover, 10 pounds of clover hay, 30 pounds of silage, 

 i pound of cottonseed meal, i pound of gluten meal, 

 and 3 pounds of dried beet pulp.
