THE FEEDING VALUE OF EOOTS 



and that is the subject which concerns us in this connection. 

 A full description of the results of the Danish feeding experi- 

 ments must be sought elsewhere. 



We have yet to compare the groups C and C+R from the 

 feeding experiments in 1889. The particulars are given in the 

 tables on preceding pages. The question was whether an 

 addition of roots to an otherwise liberal ration of concentrates, 

 hay, and straw had any effect on the yield. In a later publica- 

 tion l a summary is given of all the experiments made to solve 

 this question, on six farms through three years (1888, 1889 and 

 1890), including the experiments in 1889 above referred to. 

 It would, therefore, seem better to give some extracts from that 

 summary, which is naturally more comprehensive. The follow- 

 ing figures are calculated from a very large number of analyses 

 and weighings in connection with the feeding of 540 cows :

 of experiment, but there is an indication that the addition of
