clover, cut early enough to preserve the leaves and heads in good condition. 

 The corn meal was from Kansas corn, thoroughly dried and ground fine. The 

 bran was Minneapolis new process. 



The hay and fodder were fed long, thus necessitating much waste with the 

 corn-stalks, which might have been avoided by running the stalks through a 

 cutter, but as this was a preliminary trial, it was deemed best to take each 

 fodder in its simplest form, leaving other tests to show us the loss by feeding in 

 this way. 



Four excellent butter cows were selected and divided into two lots of two 

 each, of equal capacity for producing milk and butter as near as we could 

 judge. During the trials they held their weights and maintained their appetites 

 so well that no further mention need be made of these points. 



In every trial a week's preliminary feeding preceded the two weeks of actual 

 test, this time being considered necessary for accustoming the animals to their 

 diet, and to get the full effect of the food on the milk. 



In the first trial the ration of Lot 1 was 5 pounds of corn meal and 7 pounds 

 of bran per cow, daily, in two feeds, fed dry, and as many corn-stalks as they 

 would strip of the softer, finer parts. The ration for Lot II was the same as 

 that of Lot I, except for the corn-stalks mixed hay was substituted, a full supply 

 being kept before them. After feeding carefully for a week the ration was 

 continued and the milk and butter product saved for fourteen days. At the end 

 of this period the hay and corn-stalks of the two rations were changed about 

 for the two lots and the trial repeated. The two cows of each lot, therefore, 

 were on both sides of the trial, thus eliminating largely the errors due to the 

 difference in individuals. 



Six weeks were required to complete the test with mixed hay and corn- 

 stalks, and, this done, the whole trial was repeated, except that clover hay was 

 substituted for the mixed hay, the corn-stalk ration being continued. 



The tables here given show in a condensed form the results. 



FIRST TRIAL— CORN-STALKS VERSUS MIXED HAY. 



Two cows in each lot ; each period 14 days.
