corn, corn stover or corn ensilage in a corresponding state 

 of dryness, — corn stover leading. 



3. The net cost of feed in the case of the same ration of 

 grain feed is from one-third to one-half less per quart of 

 milk, when fodder corn, corn stover or corn ensilage serve 

 as substitutes for English hay in the daily diet of milch 

 cows ; corn fodder, as a rule, leading, while corn stover leads 

 the corn ensilage in four out of six cases. 



4. Sugar beets, as well as carrots, when fed pound for 

 pound of dry matter in place of part of the hay ration, with 

 the same kind and quantity of grain feed, have raised almost 

 without an exception the temporary yield of milk ; exceed- 

 ing, as a rule, the corn ensilage in that direction. 



5. Corn ensilage, as well as roots, proved best when fed 

 in place of one-fourth to one-half of the full hay ration. 

 From twenty-five to twenty-seven pounds of roots, or from 

 thirty-five to forty pounds of corn ensilage, per day, with all 

 the hay called for to satisfy the animal in either case, seems 

 for various reasons a good proportion, allowing the stated 

 kind and quantity of grain feed. 



6. The influence of the various diets used on the quality 

 of the milk seems to depend in a controlling degree on the 

 constitutional characteristics of the animal on trial. The 

 effect is not unfrequently in our case the revei^se in different 

 animals depending on the same diet. The increase in the 

 quantity of milk is frequently accompanied by a decrease in 

 solids.
