Notes: * DM = dry matter
-
Average weight rounded to 3 significant digits
- Manure production numbers rounded to 4 decimal places
- Blank manure production and dry matter entries indicate a non-typical housing process.
- Livestock housing capacity is rounded to 2 decimal places if above 0.2 m2/animal and 3 decimal places if below 0.2 m2/animal
- Blank livestock housing capacity values indicate that information is not available
- Livestock density is based on barn area only for a housing system(outdoor yard is not included)
- Livestock housing capacity numbers are used to develop an estimated barn size
If the farm unit has more than one type of farm animal present on it then this calculation would have to be completed for each type of animal separately, then all the results totaled to give the total NU generated by farm animals on the farm.�
