CanESS > Food Production > Animal Fat Available
Animal Fat Available is a calculator that simulates animal slaughter rates and how portions of slaughtered livestock are distributed among various edible, offal, bone meal, and animal fat products. It comprises 6 procedures:
| Inputs | Outputs |
|---|---|
| animal stock fed (animals/year) from Food Biomass Requirements | animal slaughter (animal/year) |
| average animal life (years) | mass of animal slaughter (tonnes/year) |
| animal mass at slaughter (kg/animal) |
Yearly Animal Slaughter takes animal stock fed (animals/year) from Food Biomass Requirements, average animal life (years), and animal mass at slaughter (kg/animal) to calculate animal slaughter (animal/year) and mass of animal slaughter (tonnes/year).
| Inputs | Outputs |
|---|---|
| slaughter output share (animal type, animal slaughter product class) | edible production from slaughter (tonnes/year) |
| mass of animal slaughter (tonnes/year) from (1) Yearly Animal Slaughter | offal production from slaughter (tonnes/year) |
The Slaughter procedure uses slaughter output share (animal type, animal slaughter product class) and mass of animal slaughter (tonnes/year) from (1) Yearly Animal Slaughter to compute the edible production from slaughter (tonnes/year) and offal production from slaughter (tonnes/year).
| Inputs | Outputs |
|---|---|
| animal stock fed (years) from Food Biomass Requirements | dead animals (animals/year) |
| animal mortality fraction | mass of dead animals (tonnes/year) |
| animal mass at death (kg/animal) |
Dead Animals uses animal stock fed (years) from Food Biomass Requirements, animal mortality fraction, and animal mass at death (kg/animal) to compute the number of dead animals (animals/year) and the mass of dead animals (tonnes/year).
| Inputs | Outputs |
|---|---|
| dead render output share (animal type, animal slaughter product class) | dead animal product production (tonnes/year) |
| mass of dead animals (tonnes/year) |
Dead Animal Render takes dead render output share (animal type, animal slaughter product class) and mass of dead animals (tonnes/year) from the (3) Dead Animals to compute dead animal product production (tonnes/year).
| Inputs | Outputs |
|---|---|
| product share from offal rendering (animal type, animal slaughter product class) | offal render product production (tonnes/year) |
| offal production from slaughter (tonnes/year) |
Render Production from Offal uses product share from offal rendering (animal type, animal slaughter product class) and offal production from slaughter (tonnes/year) from (2) Slaughter to calculate offal render product production (tonnes/year), which is passed to the following procedure.
| Inputs | Outputs |
|---|---|
| offal render product production (tonnes/year) | bone meal production (tonnes/year) |
| animal fat production (tonnes/year) | |
| water production (tonnes/year) |
Consolidate Production takes offal render product production (tonnes/year) from (5) Render Production from Offal to determine the fraction of which is used for bone meal production (tonnes/year), animal fat production (tonnes/year), and water production (tonnes/year).
Animal Fat Available does not pass any of the produced information to other calculators; it is simply there for calibration and informational purposes.
