Figure may vary with animal, ration, and season.
Note: Pounds of feed at least 11% to 13% moisture x 0.20 = pounds of manure (dry weight basis).  Fresh manure is 75% - 80% moisture.  Manure can be air dried in the poultry house to 15% - 25% moisture.

a.
22.5 tons
c.
38.5 tons
b.
45 tons
d.
90 tons
 

22.

aerobic
c.
hypothermic
b.
anaerobic
d.
