Step 2. Amount of Manure Produced
This worksheet
estimates the weight of solid manure produced per year.
Example Information * :
| 1. |
45 lbs x 11.6% = 5.22 lbs dry
matter |
| 2. |
5.22 lbs x 150 days = 783 lbs dry
manure/head/year |
| 3. |
783 lbs x 3000 head = 2,349,000
lbs/year |
| 4. |
2,349,00 lbs/yr ÷ 2000 lb/ton
= 1174.5 Ton dry manure/year |
* NOTE: These example calculations are assuming this
operation is feeding the animals for 150 days. The animals
enter the lot at an average weight of 600 pounds and
after 150 days leave at an average weight of 900 pounds.
Therefore for purposes of this example an average weight
of 750 pounds is used so people can follow on the referenced
tables.
