Dj the two kinds of roots replaced each other in the same 

 proportion, 6 Ibs. Eckendorf to 4 Ibs. of F. S. B. 



This led to the planning of more extended feeding ex- 

 periments for the purpose of ascertaining whether, as a general 

 rule, different kinds of roots in the food of pigs can replace each 

 other in a proportion corresponding to their contents of nourish- 

 ment (sugar and total solids or dry matter) as determined by 

 chemical analyses. The seed required for growing the roots 

 to be used for these experiments was also supplied by the 

 above-named Society, and was sown in the spring of 1890 on the 

 various farms where the experiments were to be carried out. 

 The same was done in the spring of the next year. In the 

 autumn of each year the roots were analysed, and from the 

 analyses were calculated the quantity of each kind of roots to 

 be given in place of 1 Ib. of corn. The three kinds of roots 

 tested were Eckendorf, Elvetham and Fodder Sugar Beet, and 

 the analyses showed the following percentages of sugar and 

 total solids (dry matter) for each of the two years ; 



The first year it was decided to give 8 Ibs. of Eckendorf, 

 6J Ibs. of Elvetham and 5 Ibs. of F. S. B. in place of 1 Ib. of 

 corn, as the contents of

In the second year the Eckendorf mangels were richer in 

 sugar and total solids. Therefore only 7J Ibs. were used that 

 year, containing 0*58 Ib. of sugar and 0-90 Ib. of total solids. 

 Of the two other kinds the same quantity was used each year, 

 the analyses being about the same each year.
