Mangold-Pulp (the Refuse of Beet-root Distilleries). 11 



The linseed-cake used in the experiment was good American 

 barrel-cake, and was found to contain, in 100 parts, : 



Moisture 11*56 



Oil .. 11-56 



Gum, sugar, mucilage, and digestible fibre .. .. 28*47 



* Albuminous compounds (flesh-forming matters) .. 26*37 



Woody fibre (cellulose) 13*92 



Mineral matters (ash) 8*12 



100-00 

 * Containing nitrogen 4*22 



The clover-hay chaff continued 20*12 per cent, of water, 6 '89 

 per cent, of ash, and 1*25 per cent, of nitrogen. Mangolds and 

 pulp had the composition which has been given already in the 

 preceding pages. 



Although my analyses and feeding experiments have proved 

 the pulp to be inferior in feeding properties to mangold-wurzel, 

 I am of opinion that the pulp is a very useful feeding material, 

 which, at 10s. a ton, the price at which it was sold, is certainly 

 not dear. 



I would observe, in conclusion, that more favourable results 

 than mine have been obtained with pulp in numerous experi- 

 ments carried out in France. It should be borne in mind, how- 

 ever, that in France, Champonnois' method of distillation has 

 almost entirely superseded Leplay's, and that French writers 

 expressly state that the pulp produced by Leplay's process is 

 much inferior to the pulp of distilleries where Champonnois' 

 system is adopted. The differences in the composition of the 

 pulp used in my experiments and that generally produced in 

 France may thus explain discrepancies in the results, and pro- 

 bably justify the opinion of several French authorities, who con- 

 sider the pulp, weight for weight, to be, if not superior, at least 

 equal in nutritive properties to mangolds.
