Quantities of valuable ingredients in one 

 ton of each cattle food. 



* German pounds equal 1.1 English pounds. 



f This seems to bo a smaller quantity than is being found by American analysis. 



Now if all of the ingredients contained in the various cattle foods 

 were to find their way into the solid and liquid excrements of the 

 animals fed, we could use the above figures for calculating the manu- 

 rial value obtained by feeding the materials mentioned. But there 

 is a loss incurred b}' feeding. A certain amount of the nitrogen, 

 phosphoric acid and potash contained in the food consumed goes in 

 other directions than into the manure heap,, and the quantities thus 

 turned into other channels depend upon the kind and use of the 

 animal fed. A large amount of scientific work has been done in 

 order to determine how much of the nitrogen, &c,, of an}- kind of 

 food is found in the manure it produces, and thanks to such investi- 

 gation, we can make statements that approximate very closely to the 

 truth. 



The average percentage of the nitrogen of the food that goes into 

 the solid and licpiid excrements of the cow, ox, sheep and horse is 

 approximately H'3 per cent., the lowest being that for the cow, 64 

 per cent., and the highest that for the sheep, 95.5 per cent. Of the 

 mineral substances, phosphoric acid and potash, nearly all is found 

 in the manure, with no animal falling lielow 97 per cent, of that in 

 the food. The following table* shows for itself:
