A preliminary series with 5 groups each of 5 pigs was carried 

 out by Fjord from 2nd March to 10th May, 1890, with two kinds 

 of roots, Eckendorf mangels and " Sucre blanc," a fodder 

 sugar beet with a high percentage of sugar. The seed was 

 supplied by the Society for Improving Cultivated Plants. 

 All the groups had skim-milk and butter-milk in the same 

 quantity. One group, A, had barley, the other groups had 

 half the barley replaced by roots, group B having 8 Ibs. of 

 Eckendorf mangels for each Ib. of barley, BX having only 

 6 Ibs. of Eckendorf mangels for each Ib. of barley, while groups 

 D and Dj had 6 Ibs. and 4 Ibs. respectively of Fodder Sugar 

 Beets for each Ib. of barley. These quantities were chosen 

 because of the analyses, which showed the roots to contain :

Total Solids. 



per cent. 



12-71 



19-86 



The total average food for the whole period per pig in 10 

 days, as well as the average increases in weight per pig 

 10 days, were as follows : 



The average increases show that 8 Ibs. of Eckendorf mangels 

 and 6 Ibs. of Fodder Sugar Beet had about the same feeding 

 value, and that these quantities were more than equivalent to 

 1 Ib. of barley ; and that 6 Ibs. of Eckendorf had about the same 

 feeding value as 4 Ibs. of Fodder Sugar Beet, but that these 

 quantities were hardly equal to 1 Ib. of barley. It is noteworthy 

 that the contents of sugar and of total solids in F. S. B. was 

 about 1| times that of Eckendorf, and that in groups B! and
