Animal Fat Available
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:
(1) Yearly Animal Slaughter
| Inputs | |
|---|---|
| animal stock fed (animals/year) from Food Biomass Requirements | |
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).
(2) Slaughter
Inputs:
- slaughter output share (animal type, animal slaughter product class)
- mass of animal slaughter (tonnes/year) from (1) Yearly Animal Slaughter
Outputs:
- edible production from slaughter (tonnes/year)
- 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 the preceding procedure to compute the edible production from slaughter (tonnes/year) and offal production from slaughter (tonnes/year).
(3) Dead Animals
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).
(4) Dead Animal Render
Dead Animal Render takes dead render output share (animal type, animal slaughter product class) and mass of dead animals (tonnes/year) from the previous procedure to compute dead animal product production (tonnes/year).
(5) Render Production From Offal
Render Production from Offal uses product share from offal rendering (animal type, animal slaughter product class) and offal production from slaughter (tonnes/year) from the Slaughter Procedure (2) to calculate offal render product production (tonnes/year), which is passed to the following procedure.
(6) Consolidate Production
Consolidate Production takes offal render product production (tonnes/year) 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.
