1. Scope and Applicability

This PCR covers live domestic swine managed for breeding or market production and transferred alive at the producing farm gate. It covers managed reproduction when present, farrowing, nursing, nursery and grow-finish phases, feeding, animal health, housing and environmental control, manure handling, live-weight measurement, and the farm-gate transfer attributable to the declared cohort and reporting period.

Exclude wild boar, pork and carcasses, hides, bristles, semen, embryos, separately sold veterinary or husbandry services, slaughter, dressing, post-farm transport, and all activity after slaughterhouse receipt. Backyard, intermediate, and industrial systems may coexist as declared route variants, but their feed sourcing, housing and energy, manure pathway, infrastructure, and data shall remain separately identifiable.

2. Product Category Identity

Field	Value
canonical_pcr_id	`pcr.agriculture-forestry-and-fishery-products.live-animals-and-animal-products-excluding-meat.swine-pigs`
classification_refs	`CPC 3.0: 02140`, accepted exact classification edge documented by `docs/adr/cpc-02140.md`
covered_products	Live domestic swine/pigs for breeding or market production, transferred alive at the producing farm gate
excluded_products	Wild boar; pork, carcasses, skins and bristles; semen and embryos; separately sold husbandry or veterinary services; animals after slaughterhouse receipt
representative_product	Live market pig measured by live-weight mass immediately before farm-gate transfer
production_route	Managed swine production through the actual declared class-specific farm gate; breeding/farrowing and nursery/grow-finish are included only when operated, with manure responsibility for every represented animal phase and one common final handover
market_state	Live animal at the producing farm gate, before post-farm transport or slaughter

The managed-production parent is swine husbandry through live-animal transfer. Backyard, intermediate, and industrial variants are alternative implementations: they may coexist within a reporting organization only when inventories and allocation drivers remain route-specific; otherwise select one route. Route deltas shall identify changes in feed origin, housing/environmental control, energy, manure pathway, shared assets, phase topology, and data quality, supported by current foreground evidence and the FAO LEAP pig guidance.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
`measure_live_weight`	reference animal and all live-animal transfers	Mass	kg live weight	Use calibrated scale records immediately before the declared handover. Head count is a parallel activity datum and shall not replace mass.
`convert_group_weight`	group weighing	Mass; count	kg; head	Divide the measured net group mass only for per-head checks; preserve total cohort mass and tare records.
`measure_feed`	feed inputs	Mass; dry matter where reported	kg as-fed; kg dry matter	Record each feed/formulation as supplied, moisture or dry-matter basis, and supplier/source; do not combine unlike feeds without composition records.
`measure_water_energy`	water and energy inputs	Volume or mass; carrier-specific energy	m3 or kg; kWh or MJ	Preserve measured water volume and each energy carrier; document conversions and meter allocation.
`measure_manure`	manure routes	Mass or volume; dry matter; N and volatile solids when used	kg or m3; kg DM; kg N; kg VS	Record manure state, storage/treatment route, destination, and the analytical or calculated basis used for emissions and exported nutrients.
`inventory_reference_normalization`	all inventory rows	Actual flow property	exchange unit per reference flow	The inventory and collection aggregation fields below express final amounts per declared reference flow. Keep all raw collection records, original denominator qualifiers, route/period strata, unit conversions and allocation requirements. For each flow, first obtain its attributable amount in its own numerator unit using the existing rules; then divide by the measured accepted reference-output quantity of the same scope and multiply by the declared reference quantity. Do not mix species, states, gates or incompatible routes; count transfers and shared burdens once. A missing, zero or untraceable accepted-output denominator is a blocking data-quality issue. Keep provisional QA ranges on their explicitly stated bases; they are not conversion factors or production defaults. These are final foreground-package contributions, not replacements for stage quantitative references or stage-native unit-process datasets. Retain stage records separately. Compute normalized amount = attributable raw amount * declared reference quantity / measured accepted final reference-output quantity. Apply normalization exactly once.
`stage_throughput_linkage`	stage records and final package contributions	Actual flow property and its stated raw basis	retain native numerator and stage denominator units	Keep the original lot, event, cohort, period and stage denominators with their units. Reconstruct the attributable numerator A with measured stage quantity Q_stage and documented attribution before final normalization. If a quoted amount a_B corresponds to an explicit stage basis B_stage (for example, 1000 kg), use A = a_B * Q_stage / B_stage. If r_stage is already an intensity in exchange-unit per stage-unit, instead use A = r_stage * Q_stage, with no second division by B_stage. A raw attributable total is used directly. Final contribution = A * declared reference quantity / measured accepted final output. Convert compatible units explicitly and apply each attribution/allocation share exactly once; never treat a quoted amount or intensity as a raw total. Link stage transfers, losses, rejects, stocks, shared services and allocation to the same actual route, period and final-output stratum. For a 1000 kg basis retain 1000 kg explicitly. Do not assume unit yield, equal fresh/dried mass, equal head mass, equal dose quality or interchangeable gates. Missing links, unsupported unit conversion, zero denominators and untraceable allocation block dataset production. Stage-native datasets retain their own stage reference; package contributions are a separate projection.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Breeding/replacement animals and admitted piglets enter in their measured live state; feed, water, energy, veterinary products, and other managed inputs enter at the farm boundary
starting_condition_role	Managed biological production from admitted animals and inputs through live-pig farm-gate transfer
product_classification_scope	Live domestic swine before slaughter; meat, carcass, service, germplasm, and post-farm transport systems are outside scope
recursive_input_rule	Purchased or transferred live swine of the same category are recorded as upstream Product inputs with their actual class, live weight, origin, and gate; they shall not be represented by the reference output of the receiving process without a distinct upstream dataset.
upstream_dataset_requirement	Match animal class, live-weight basis, production system, origin, geography, period, and handover gate; feed datasets shall match formulation or ingredient identity and delivery state.
disclosure	Declare route variant, cohort phases, reporting period, animal movements, mortality, intended outputs, manure destinations, shared infrastructure, attribution choices, and unresolved identities.

Boundary Rules

rule_id	Applies to	Rule	source_ids
`boundary_farm_gate`	all datasets	Include managed production through live-weight measurement and transfer at the producing farm gate; exclude post-transfer transport, slaughter, dressing, and processing.	`fao-leap-pig-2018`

Purchased piglets retain their upstream burden when admitted to an operated receiving phase.	`fao-leap-pig-2018`; `ipcc-2019-livestock-manure`
`boundary_route_variant`	backyard, intermediate, or industrial route	Identify route-specific topology and inventory deltas for feed origin, housing and environmental control, energy, manure pathway, infrastructure, and data collection; do not average mutually exclusive routes without transparent weighting.	`fao-leap-pig-2018`
`boundary_periods`	breeding herd, pig cohort, and shared assets	Index breeding cycle, nursing, nursery, grow-finish, manure service period, and infrastructure service period; assign each input, output, loss, and event once.	`fao-leap-pig-2018`
`boundary_shared_assets`	housing, ventilation, feeding, water, storage, and manure assets	Identify all consuming nodes and service periods and allocate by measured occupancy, live-weight-days, throughput, metered use, or another documented causal driver without duplicate burdens.

Process: Actual class-specific farm-gate handover (`reference_handover`)

Select one actual terminal source for each accepted lot: live_piglet_output for a piglet-producing route without a later operated growth phase, live_grow_finish_output for an operated nursery/growth/finishing route, or breeding_animal_output for a separately transferred breeding/culled-animal reference lot. Keep class, lot, period and gate separate. The source-to-handover link describes the same physical event; it creates no extra husbandry, handling, transport or external sale. At package aggregation cancel the matched internal source and input; live_pig_output is the sole external reference for that lot. A missing source, missing producing phase or unsupported route blocks production.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
`allocation_output_set`	all intended outputs	Enumerate live market pigs, independently transferred piglets, breeding animals, culled animals, and exported manure. Mortalities and unusable manure remain losses/waste unless an evidenced intended handover changes their role.	`fao-leap-pig-2018`
`allocation_physical_first`	multi-output process	First subdivide measured phase-specific inputs and emissions. For remaining inseparable burdens, use a documented causal physical driver such as live-weight gain, live-weight-days, nutrient content, or measured service; economic allocation requires justification and sensitivity disclosure.	`fao-leap-pig-2018`
`allocation_period`	breeding herd and cohort phases	Link breeding, nursing, nursery, grow-finish, replacement, culling, and termination events to declared periods and outputs; record carryover and prevent double attribution between cohorts.	`fao-leap-pig-2018`
`allocation_shared_infrastructure`	shared buildings and equipment	Enumerate consuming nodes and service periods; allocate each asset once by measured occupancy, live-weight-days, throughput, run time, or metered use and retain the selected driver's evidence.
`allocation_manure`	exported manure	Record the selected attribution or substitution treatment, destination, mass, dry matter and nutrient content. Do not apply both allocated burdens and an avoided-product credit to the same output unless the study method explicitly requires and discloses both.	`fao-leap-nutrient-flows-2018`

Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

8. Foreground Data Collection, Calculation, and Quality Rules

Specific input identification before dataset completion

Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output. The former aggregate range is not a component limit or consumption default.

requirement_id	collection_protocol_id	Preserved collection scope
`health_product_input_specific_input`	`cp_health_mortality_records`	Operation nursery_grow_finish: Record actual vaccine, medicine, disinfectant, and other health-product formulations separately; UUID unresolved.

Original collection denominator kind: process_output. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.

Include actual waste treatment and manure contributions once, not as a second feed-production burden.	`cp_feed_supply_and_intake`	separate feed supply, intake and loss quantities, in matched as-fed/DM units	`review-fao-pig-lca-2018`
`calc_manure_n2o_coverage`	`manure_nitrous_oxide_output`	For each actual manure stage, calculate direct N2O, volatilisation/deposition-derived indirect N2O, and applicable leaching/runoff-derived indirect N2O separately with documented species/system activity and factor basis. Convert N2O-N to molecular N2O by 44/28 once; do not reconvert molecular masses. Retain component worksheets. Where an existing N2O card covers both direct and indirect emissions, report their non-overlapping sum; where separate direct/indirect cards exist, assign each component once to its matching card and never also report the sum. Pasture deposition and land application use the managed-soil method, not a manure-storage factor. Assign foreground versus linked treatment/pasture coverage explicitly; a manure export does not erase earlier emissions, and already covered downstream emissions are not repeated. Account for stock, transfers and previous N losses in the nitrogen cascade; indirect N2O is a downstream transformation of its precursor, not a second source-stage N loss. Normalize attributed molecular masses once to the accepted reference output. Document inapplicability; absent pathway data are not zero.	`cp_manure_n2o_coverage`	kg molecular N2O by pathway and assigned existing card	`ipcc-2019-livestock-manure`; `ipcc-managed-soils-2019`
`chemical_species_mass_accounting`	`elementary_nutrient_emissions`	Final elementary exchanges use the mass of the identified substance and one actual receiving compartment. Keep nutrient/activity ledgers separate: species-specific N2O-N × 44/28 gives N2O, NH3-N × 17/14 gives NH3, nitrate-N × 62/14 gives nitrate, and phosphate-P × 95/31 gives phosphate. If the selected flow is elemental phosphorus instead, report kg P and convert phosphate mass by 31/95 only when that species basis is evidenced. Apply a conversion exactly once only when the method output is on the elemental basis; measured compound mass is not reconverted. Total nutrient losses cannot be assigned to a single species without a supported split, and residual/retained soil nutrient is not an emission. Keep direct/indirect pathway ledgers and avoid repeating a pathway already included in the chosen method or upstream inventory. Factor uncertainty ranges screen factors on their stated basis, not final compound amounts or admissible site emissions. Normalize the attributable compound mass once using the accepted reference quantity and the matched measured output. Unknown activity, identity or compartment remains an evidence gap and blocks a completeness claim.	`cp_manure_records`; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
`dq_identity_gate`	reference output	Retain animal class, route, live-weight basis, producing-farm gate, timestamp, origin/destination, and signed transfer; no feed-grade, count-only, at-plant, meat, or carcass substitute.	scale and transfer records; unresolved UUID review note
`dq_route_phase`	route variants and periods	Identify backyard/intermediate/industrial route, all represented phases and sites, and phase dates; justify any aggregation and preserve weights.	route declaration; herd and facility records
`dq_completeness`	inventory	Reconcile animals, feed, water/energy meters, mortalities, manure, intended outputs, and stock/storage changes over the same period.	signed reconciliation and exception log
`dq_method_parameters`	calculated emissions and allocation	Retain method version, every factor and parameter, source, units, conversions, allocation driver, and sensitivity case.	calculation workbook and source references
`dq_shared_assets`	infrastructure	List each shared asset, consuming nodes, service period, and selected causal driver; demonstrate the burden is assigned once.	asset register; meter/run-time/occupancy evidence

9. Validation Rules

rule_id	Applies to	Rule	severity
`validate_reference_identity`	reference flow	Fail if the output is not live domestic swine weighed by mass at the producing farm gate, or if either rejected candidate UUID is used.	error
`validate_terminal_route`	phase topology and reference handover	Require one actual terminal source matched to live_pig_output by class, lot, period, gate and accepted mass. A piglet-only route without nursery/growth omits nursery_grow_finish; a growth route retains only operated phases and linked upstream piglet burdens. Reject missing producing phases, imputed later finishing, combined incompatible classes, double-counted internal transfers or more than one reference sale for the same lot.	error
`validate_reference_uuid`	reference binding	Keep the reference Product-flow UUID empty until one compatible product identity is detail-confirmed. Independently confirmed Mass property and unit-group UUIDs are support references only; unresolved product identity blocks active/publication readiness.	error
`validate_route_delta`	route variants	Fail if backyard, intermediate, or industrial routes are combined without route-specific topology, inventory categories, calculation/validation deltas, current evidence, and transparent weights.	error
`validate_phase_period`	phases and reporting periods	Fail when breeding, nursing, nursery, grow-finish, manure, replacement, culling, or asset service periods are relevant but unindexed, overlap without explanation, or are attributed twice.	error
`validate_output_roles`	intended outputs, residues, and waste	Fail unless every live output and exported manure handover is recorded and mortalities/unusable manure are distinguished from intended products.	error
`validate_shared_assets`	shared infrastructure	Fail unless each shared asset names at least two consuming nodes or periods, its service boundary and driver, and a no-double-counting check.	error
`validate_flow_identity`	unresolved Product inputs	Determine the actual energy carrier, water supply and any foreground-controlled inbound transport from records; final generated exchanges require compatible verified concrete UUIDs.	error
`validate_emission_identity`	elementary outputs	Fail fixed binding unless substance, receiving compartment, flow property, unit group, and support references are detail-confirmed; broad pollutant labels remain unresolved.	error
`validate_ranges`	all important flows	For every supplied quantitative screen, verify the concrete exchange, bounds, compatible unit and denominator, basis, applicability, evidence kind and external sources; keep EN/ZH/projection equivalent. Provisional reasoned estimates are non-enforcing review prompts, not default quantities, allowed losses or proof of completeness. Where no compatible quantitative bound is supported, explicitly report screening unavailable and review measurements, matched component balances and uncertainty; do not invent a range to satisfy this check. Final reference normalization remains exact and is not an empirical yield. Actual exchange quantities, protocols and compatible unit/conversion evidence are required independently of screening.	error
`validate_mass_n_balance`	animals and manure	Investigate unexplained animal mass, manure mass, or nitrogen imbalance; record storage change and transformations rather than forcing closure.	error
`v_feed_loss_burden`	Feed balances	Reject a feed-input inventory that subtracts in-boundary wastage without retaining its upstream burden. Match intake, losses, stocks and unused returns, and document the loss treatment; no automatic co-product credit.	`review-fao-pig-lca-2018`
`v_foreground_emission_responsibility`	Actual operated nodes and linked services	Record responsibility for on-site fuel combustion and refrigerant leakage when applicable: either quantified foreground emissions or a named linked process explicitly covering them, never merely a fuel-supply or electricity-production input. Assess special-taxon biological and residue emissions using species/route evidence, without a generic livestock factor. Identify any unresolved pathway and withhold a completeness claim; document supported absence and prevent duplicate upstream/downstream accounting.
`v_feed_supply_intake_separation`	All feed inputs	Reject an upstream feed inventory reduced by in-boundary refusal, spoilage or discarded leftovers without retaining their production burden. Reconcile supply, intake, stock, transfers and loss destinations under calc_feed_supply_and_intake. Do not reuse intake as supplied feed, assume zero-burden on-site feed or grant automatic avoided-product credits.	`review-fao-pig-lca-2018`
`v_manure_n2o_coverage`	Applicable manure and managed-soil N pathways	Require explicit direct and indirect pathway coverage, stage N balances and molecular-mass conversion. Map each component to an existing N2O card or an explicitly covering linked process once under calc_manure_n2o_coverage. Missing indirect-pathway evidence prevents a completeness claim; no default zero or duplicate aggregate-plus-components.	`ipcc-2019-livestock-manure`; `ipcc-managed-soils-2019`

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`boundary_farm_gate`	all datasets	Include managed production through live-weight measurement and transfer at the producing farm gate; exclude post-transfer transport, slaughter, dressing, and processing.	fao-leap-pig-2018
`boundary_managed_phases`	production cohort	Include breeding/gestation/farrowing, nursing, nursery and grow-finish only when actually operated within the represented boundary; retain health, housing and manure responsibility for those phases. A piglet-only route ends at the actual piglet-producing gate and does not acquire unoperated nursery/grow-finish burdens. Purchased piglets retain their upstream burden when admitted to an operated receiving phase.	fao-leap-pig-2018, ipcc-2019-livestock-manure
`boundary_route_variant`	backyard, intermediate, or industrial route	Identify route-specific topology and inventory deltas for feed origin, housing and environmental control, energy, manure pathway, infrastructure, and data collection; do not average mutually exclusive routes without transparent weighting.	fao-leap-pig-2018
`boundary_periods`	breeding herd, pig cohort, and shared assets	Index breeding cycle, nursing, nursery, grow-finish, manure service period, and infrastructure service period; assign each input, output, loss, and event once.	fao-leap-pig-2018
`boundary_shared_assets`	housing, ventilation, feeding, water, storage, and manure assets	Identify all consuming nodes and service periods and allocate by measured occupancy, live-weight-days, throughput, metered use, or another documented causal driver without duplicate burdens.

Allocation rules · 6

Rule ID	Applies to	Rule	Source IDs
`allocation_output_set`	all intended outputs	Enumerate live market pigs, independently transferred piglets, breeding animals, culled animals, and exported manure. Mortalities and unusable manure remain losses/waste unless an evidenced intended handover changes their role.	fao-leap-pig-2018
`allocation_physical_first`	multi-output process	First subdivide measured phase-specific inputs and emissions. For remaining inseparable burdens, use a documented causal physical driver such as live-weight gain, live-weight-days, nutrient content, or measured service; economic allocation requires justification and sensitivity disclosure.	fao-leap-pig-2018
`allocation_period`	breeding herd and cohort phases	Link breeding, nursing, nursery, grow-finish, replacement, culling, and termination events to declared periods and outputs; record carryover and prevent double attribution between cohorts.	fao-leap-pig-2018
`allocation_shared_infrastructure`	shared buildings and equipment	Enumerate consuming nodes and service periods; allocate each asset once by measured occupancy, live-weight-days, throughput, run time, or metered use and retain the selected driver's evidence.
`allocation_manure`	exported manure	Record the selected attribution or substitution treatment, destination, mass, dry matter and nutrient content. Do not apply both allocated burdens and an avoided-product credit to the same output unless the study method explicitly requires and discloses both.	fao-leap-nutrient-flows-2018
`allocation_rule_6`	foreground_burden_allocation	Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

`validate_reference_identity`	reference flow	Fail if the output is not live domestic swine weighed by mass at the producing farm gate, or if either rejected candidate UUID is used.
`validate_terminal_route`	phase topology and reference handover	Require one actual terminal source matched to live_pig_output by class, lot, period, gate and accepted mass.
