TABLE 3. 

 Average for both lots with and without roots. 



In Table 3 the results were averaged from the sixteen cows, while on 

 the ^'root ration," against the same sixteen when fed without roots. Here 

 it may be seen that both the milk and butter fat were increased by the 

 addition of roots, but the added cost was great enough to render it un- 

 profitable feeding, the average cost of production being 5 cents greater 

 per 100 lbs. of milk and 1.12 cents greater per pound of butter fat. 



FEEDING TRIAI 



-NUMBER TWO. 



In the spring of 1906 fourteen cows from the Grade Herd No. 1 were 

 selected in the same manner as in the previous trial and divided into two 

 lots of seven each. The feeding, care and treatment previous to this ex- 

 periment had been the same. The experiment covered two periods of 

 four weeks each. Four days were taken at the start to get Lot 1 on the 

 root ration, and four days to get Lot 2 on the root ration at the beginning 

 of the second period. During the first period Lot 1 received in addition 

 to the regular herd ration of silage, clover hay, and grain, 20 lbs. per 

 head daily of sliced roots. During the second period the roots were 

 placed in the ration of Lot 2, and Lot 1 received none. The roots were 

 fed twice daily, 10 lbs. at the morning and 10 lbs. at the evening feed. 

 Grain Mixture No. 5 was replaced by Grain Mixture No. 4 during the 

 latter part of the test. About the middle of the last period the silage 

 supply became exhausted, and beet pulp, thoroughly moistened, was sub- 

 stituted in its place. The dried beet pulp used for this purpose was 

 soaked several hours. Feeding the moistened pulp increased the milk 

 flow very markedly, but as it was fed in equal amounts to both lots the 

 accuracy of the results need not be affected. 



Lot 1 consisted of cows Nos. 12, 18, 23, 24, 25, 28, 32. Lot 2, cows Nos. 

 11, 13, 19, 20, 26, 27 and 31.
