Animal Fat Available is a calculator that simulates animal slaughter rates and how portions of slaughtered livestock are distributed among various edible, [[wp>offal]], bone meal, and animal fat products. It comprises 6 procedures:
===(1) Yearly Animal Slaughter===
^ Inputs ^ Outputs ^
|//animal stock fed// (animals/year) from [[CanESS:foodProd:foodBMReq|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 [[CanESS:foodProd:foodBMReq|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 ^ 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).

===(3) Dead Animals===
^ Inputs ^ Outputs ^
|//animal stock fed// (years) from [[CanESS:foodProd:foodBMReq|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 [[CanESS:foodProd:foodBMReq|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===
^ 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).
===(5) Render Production From Offal===
^ 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.
===(6) Consolidate Production===
^ 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).
