### Mappings and Rationale
- **Lifecycle Stages:** To provide a complete glossary mapping, all life stages (e.g., `beefCattleBull`, `dairyCattleCowLactating`, `pigSow`) were mapped to the species-level concentration data provided by SALCA for "Cattle", "Pigs", and "Poultry".
- **Species Proxies:** Sheep, goats, and horses were mapped to the cattle concentration values, as ruminants/large herbivores are assumed to have similar body concentrations of heavy metals in the SALCA model defaults.
