FEEDING TRIAL NUMBER ONE. ' 



In the spring of 1905, sixteen cows of Grade Herd No. 1 were selected 

 as described above and divided into two lots of eight cows each. During 

 the first period of four weeks. Lot 1 received, in addition to the regular 

 herd ration of silage, hay and grain, 15 pounds of roots per head daily. 

 During the second period, Lot 2 received the same amount of roots in- 

 stead of Lot 1. The last period, however, covered only two weeks, as the 

 supply of roots at that time was exhausted and the results given herein 

 are reported in weekly averages in order to furnish a fair basis for com- 

 parison. Lot 1 consisted of Nos. 11, 12, 14, 19, 21, 23, 24, 31. Lot 2, of 

 Nos. 13, 17, 20, 22, 25, 27, 28, 32.
