PERCENTAGE OF FOOD VOIDED IN THE SOLID AND LIQUID 

 EXCREMENTS. 



According to Wolff, the following table shows the per- 

 centage of the dry substance of the food which is voided 

 in the solid and liquid excrements of the cow, ox, sheep, 

 and horse : 



Cow. Ox. Sheep. Horse. Average. 



Solid excreta . 38.0 44.0 42.6 46.7 42.8 

 Urine . . 5.8 6.3 6.8 5.7 6.2 



Total . 43.8 50.3 49.4 52.4 49.0

 PIG EXCREMENTS. 



The excrements voided by pigs are poor in manurial 

 constituents, because the food on which they are fed is 

 generally of a very poor nature. In their case the urine 

 is always very much richer in manurial ingredients than 

 the solid excreta. The relative composition of the solid ex- 

 creta and the urine will be best illustrated by quoting some 

 experiments carried out by Wolff on this subject. The ex- 

 periments were carried out with two pigs nine and a half 

 months old, and each 121.9 kilogrammes (a kilogramme is 

 equal to about 2^ Ib.) in weight. The first consumed daily 

 1000 grammes of barley, 5000 grammes of potatoes, and 

 2572 grammes of sour milk. The second one consumed 

 the same quantities of potatoes and sour milk as the first, 

 and 1000 grammes of peas. The following table 1 gives the 

 results of excreta and urine daily voided, in grammes :
