AN EXPERIMENT TO COMPARE GLUTEN MEAL WITH COTTON- 

 SEED MEAL FOR MILCH COWS. 



Results : The two foods proved to have equal efficiency when 

 fed in amounts to furnish equal quantities of digestible matter. 



AN EXPERIMENT TO COMPARE GROUND OATS WITH WHEAT 

 BRAN AS FOOD FOR MILCH COWS. 



Results: The ground oat ration produced slightly more milk, 

 solids and fat than the bran, and when they can be purchased 

 at about the same price make an excellent substitute for it. 



AN EXPERIMENT TO SUBSTITUTE SILAGE FOR A PART OF THE GRAIN 

 RATION" OF MILCH COWS. 



The silage used was the so-called Robertson mixture, consist- 

 ing of matured corn (ears glazed), sun flower heads and horse 

 beans. Six cows were used. The rations fed were : ( 1 ) Hay, 

 15 pounds; silage 20 pounds: grain, 8 pounds. (2) Hay, 15 

 pounds ; silage, 35 pounds : grain, 4 pounds. 



Results: Ration 2 in which silage was substituted for a part 

 of the grain ration was fully equal to ration 1, producing as 

 much milk and a greater gain in weight of cows. 



AN EXPERIMENT IN FEEDING NUTRIOTONE. 



This is a patent food or medicine, claimed by manufacturers 

 to stimulate growth and milk production. 



Five cows were fed three periods of twenty-one days each 

 liberal rations of hay and grain. The rations were weighed. In 

 the second feeding period, two spoonfuls of nutriotone (according 

 to directions in the package) were added to the grain ration. 



Results: The nutriotone had no visible effect. The cows in 

 twenty-one days without nutritone produced 2,281 pounds milk 

 and 101 pounds fat. The cows in twenty-one days with 

 nutriotone produced 2,264 pounds milk and 101 pounds fat. 



AN EXPERIMENT TO TEST THE EFFECT OF FOOD ON THE HARD- 

 NESS OF BUTTER AND COMPOSITION OF BUTTER FAT. 



The primary object of the experiment was to study the effect 

 of liberal rations of corn gluten meals containing large and
