Table 53. 

 Summarized results with herd U. Tests Nos. 60 and 62. 



[First test Dec. 26, igoo-Jan. 5, 1901. Second test Jan. 21-Feb. 2, 1901.] 



Table 53 gives the results obtained in the separate tests with 

 the different groups of cows. The average cost of the ration 

 used in the second test was 1.3 cents more than in the first 

 test. The average yield of milk was .6 pound more and of 

 butter .12 pound more in the second test than in the first. 

 The cost of producing 100 pounds of milk was 3.0 cents more, 

 while the cost of one pound of butter was nearly one cent less 

 in the second than in the first test. When the average food 

 cost of one pound of butter in the second test is compared with 

 the average food cost of the same amount of butter in the first 

 test, it will be noticed that the rations providing over 2.56 

 pounds of protein were less economical than the average ration 

 in the first test, which provided only 1.77 pounds of protein. 

 Although the average milk yield was slightly more in the 

 second test than in the first, the cost of milk was not reduced; 

 while in the case of the butter the yield was greater in the
