AMOUNT OF MANURE MADE ON THE FARM 



The amount of manure that will be made during 

 a year by a given number of animals is capable of 

 fairly accurate calculation. A common estimate is : 



Horse, 12,000 Ibs. of solids, and 3,000 Ibs. of liquids. 



Cow, 20.000 " " " " 8,000 " " 



Sheep, 760 " " " " 380 * 



Swine, 1,800 " " " " 1,200 " " 



Another method, resulting from many careful 

 experiments, is to multiply the amount of "dry 

 matter" in the food for one year by 2.1 for the 

 horse, by 3.8 for the cow, by 1.8 for the sheep. 

 Add to these figures the weight of bedding used. 

 Thus if a cow eats thirty pounds of dry matter a 

 day she will produce about 30 x 3.8, or one hundred 

 and fourteen pounds of manure a day, besides the 

 bedding. The age of the animals, tneir condition 

 and their food influence the amount of manure 

 made. 



According to Heiden's rule for calculating man- 

 ure, the following quantities of cow manure may be 

 expected from feeding one ton of the feeds named:
