# Turkeys

## 1. Scope and Applicability

This PCR governs live turkeys at the producing hatchery or rearing/breeder farm gate. It covers day-old poults and older birds as two mutually exclusive final-output routes. Declare head count, sampled live mass, age/class, sex where relevant, cohort and transfer state. Exclude turkey meat, slaughter, post-gate freight and independently marketed hatching eggs as the reference product.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | `pcr.agriculture-forestry-and-fishery-products.live-animals-and-animal-products-excluding-meat.turkeys` |
| classification_refs | CPC 3.0 `02152`, Turkeys |
| covered_products | live day-old turkey poults at producer hatchery gate; older live turkeys at producing farm gate |
| excluded_products | chicken, turkey eggs sold independently, slaughtered birds and turkey meat |
| representative_product | live turkey at a declared producer gate and age class |
| production_route | integrated or purchased hatching eggs → hatchery poult; or purchased/internally transferred poult → rearing → catching |
| market_state | live and unprocessed; age, gate, count and live mass declared |

The managed-biological-production parent has two route deltas: incubation and hatch selection begin with eggs, whereas growth and catching begin with poults. Their process topology, inputs, yield equations and validation differ. A vertically integrated producer can operate both stages, but must record an internal poult transfer once rather than two final sales for the same bird.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | live turkey at declared producer hatchery or farm gate |
| How much | 1 kg net live weight |
| How well | saleable live bird; species, age/class, count and sampled mass declared |
| How long or cycle | hatch batch or rearing cohort, with linked breeder and shared-asset periods |
| reference_flow_link | `reference_product_handover` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Live turkeys at hatchery or farm gate, age class declared |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | turkey species; day-old or older route; hatchery/farm gate; head count; sampled live mass; age/class; cohort; origin; sex if relevant; mortality; transfer state |

Instantiate one foreground reference from the actual handed-over lot, with all required qualifiers. The category may cover alternative states and producer gates, but each package has one declared species/state/gate/grade stratum and one measured accepted reference-output denominator. Do not pool incompatible states or claim equal service from equal mass. Route-specific source rows and reference_handover describe the same physical boundary event; their linked internal transfer is not another sale or another physical operation.

The two verified route UUIDs do not identify this combined broad reference.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `m_live_mass` | final birds | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Multiply saleable head count by sampled live mass within age/class strata and reconcile weigh slips. |
| `m_eggs` | hatching eggs | count and mass | eggs, kg | Keep received, hatched, rejected and unhatched counts distinct; convert with sampled egg mass. |
| `m_feed` | feed | as-fed mass and dry matter | kg | Convert using observed moisture and retain feed source. |
| `m_emissions` | air releases | pollutant mass | kg | Keep substance, receiving medium, manure pathway and factor tier distinct. |
| `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

The hatchery route starts with hatching eggs bearing their upstream burden and includes incubation, hatch-pull, selection and hatchery-gate handover. An integrated breeder flock supplies eggs as an upstream node only when not also taking purchased-egg burden. The older-bird route starts with poults bearing their prior hatchery burden and includes feed, water, housing, litter/manure, health, growth and separate catching to farm gate. Catching is an independent capture node because the standing flock becomes counted, weighed saleable live birds at a handover; it is not growth or slaughter. Rejects, mortality and unmarketed litter are losses or waste. Record independently marketed manure, hatching eggs and spent breeders as intended co-products only on actual transfer. Shared incubators, buildings, utilities and equipment are attributed once over their consuming nodes and periods.

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | accepted hatching eggs at hatchery receipt or live poults at rearing receipt; integrated opening breeder flock if used |
| starting_condition_role | upstream biological stock or purchased intermediate with prior burden, not another final turkey sale |
| product_classification_scope | CPC 3.0 `02152`, live turkeys |
| recursive_input_rule | same-category incoming live poults retain prior stage burden; internal transfers are not independent final outputs |
| upstream_dataset_requirement | supplier evidence for eggs/poults, feed, energy, water, bedding and treatment services or disclosed gaps |
| disclosure | route, gate, age/class, batch/cohort, stock changes, mortality, rejects, manure fate, shared asset allocation and unresolved identity |

### Boundary Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `b_routes` | all birds | Select hatchery day-old or farm older-bird final gate; predecessor stages transfer once. | `unsd-cpc-2025`; `fao-leap-poultry-2016` |
| `b_hatchery` | poults | Include accepted hatching eggs, incubation, hatch-pull, losses and hatchery dispatch. | `fao-leap-poultry-2016` |
| `b_rearing` | older birds | Include received poults, feed, water, housing, manure, mortality and live catching. | `fao-leap-poultry-2016`; `ipcc-livestock-2019` |
| `b_exclusion` | producer gate | Exclude slaughter, meat processing and post-gate freight; include inbound service only when actually bought within boundary. | `fao-leap-poultry-2016` |
| `reference_handover_linkage` | actual reference-product boundary | Record reference_handover as the same physical producer handover already represented by its source rows. It must not extend the gate or insert new processing, capture, storage, transport, service or capital burdens. For a unit-process projection, keep the actually operated stage references; the handover record may be a boundary interface in the resulting foreground package, not an invented standalone operation. Select one actual qualified route/output stratum; trace matching source and input as internal transfers and expose the accepted reference product once. If the source already ended at this gate, partition its existing handover responsibility without counting it again. |  |

###### Electricity at the equipment supply point (`incubation_energy_electricity`)

**Collection scope and applicability for incubation_energy.** The following concrete identities have separate cards and apply only when use or generation is evidenced inside the original process scope. They are not mandatory inputs or a default recipe. Document non-use; missing records are not zero. Add a separate concrete card for any other actual material instead of substituting one of these names or UUIDs. Preserve attribution and boundaries and avoid double counting components included in outsourced services.

Record actual electricity and fuel carriers, including shared-meter attribution.
Denominator and scope requirements：per kg saleable poult
Raw quantity and calculation requirements: metered or allocated carrier consumption Original collection denominator kind: process_output.

Confirm identity, grade, state and unit from equipment, supplier and contemporaneous measurements; the product UUID does not establish actual use or upstream-provider compatibility. Retain the electricity supply point, fuel grade, density and heating-value basis. Distinguish purchased heat from on-site fuel conversion without counting its input fuel again.

- Selected flow: Alternating current `455f0ef5-6118-4f2b-a3f5-1f75e0afe3ca`

###### Saleable day-old poults (`day_old_poults`)

Count and weigh live selected poults at hatchery gate; integrated transfer to rearing is not a second final sale.

Denominator and scope requirements：per hatch batch, then 1 kg final route output

Raw quantity and calculation requirements: saleable count times sampled live mass Original collection denominator kind: process_output.

Producer-handover linkage: Only when selected as the actual terminal source for this route, this state/gate-specific row supplies the same accepted physical goods to reference_handover_input. In that case it is an internal handover record, not a second external reference sale; otherwise retain its original intermediate role. Retain its exact identity and original route condition. Choose the actual terminal source, not all successive transfers; match the same lot and compatible species/state/gate evidence. A narrower fixed gate or species is never broadened. The handover interface adds no processing, transport, yield assumption or repeated handling burden.

###### Alternating current (`rearing_energy_electricity`)

Only for documented alternating-current equipment within this operation. Record voltage and supply technology; convert metered kWh with 1 kWh = 3.6 MJ. Other power sources require their actual carrier. Apply `rearing_energy_specific_input`; this example is not mandatory. Do not double count inclusive machinery services or a purchased-electricity supply for electricity transferred internally from an on-site generator. Actual fuel combustion and generator emissions remain separately accountable.

###### Saleable older live turkeys (`farm_live_turkeys`)

Count and weigh live unprocessed birds at farm gate, before slaughter or outbound transport.

Denominator and scope requirements：per catching batch, then 1 kg final route output

Raw quantity and calculation requirements: saleable head count times sampled live mass Original collection denominator kind: process_output.

Producer-handover linkage: Only when selected as the actual terminal source for this route, this state/gate-specific row supplies the same accepted physical goods to reference_handover_input. In that case it is an internal handover record, not a second external reference sale; otherwise retain its original intermediate role. Retain its exact identity and original route condition. Choose the actual terminal source, not all successive transfers; match the same lot and compatible species/state/gate evidence. A narrower fixed gate or species is never broadened. The handover interface adds no processing, transport, yield assumption or repeated handling burden.

### Process: Actual producer reference-product handover (`reference_handover`)

Instantiate one foreground reference from the actual handed-over lot, with all required qualifiers. The category may cover alternative states and producer gates, but each package has one declared species/state/gate/grade stratum and one measured accepted reference-output denominator. Do not pool incompatible states or claim equal service from equal mass. Route-specific source rows and reference_handover describe the same physical boundary event; their linked internal transfer is not another sale or another physical operation.

###### Live turkeys at hatchery or farm gate, age class declared for actual producer-handover linkage (`reference_handover_input`)

This input matches the accepted goods represented by `day_old_poults`, `farm_live_turkeys` under their unchanged route conditions. It is an internal source-to-handover linkage, not a newly purchased same-category good and not extra production. The matching source and input cancel at the package boundary.

The actual route/state/gate is selected from foreground handover evidence; retain every required qualifier. Use the actual terminal source for the same accepted physical lot, not every successive stage transfer. Fixed source identities apply only to their exact species/state/gate; use an unbound compatible source role for other covered routes and resolve the actual foreground exchange before final dataset creation.

Selected source/interface rows: `day_old_poults`, `farm_live_turkeys`

Required product-instance qualifiers: turkey species; day-old or older route; hatchery/farm gate; head count; sampled live mass; age/class; cohort; origin; sex if relevant; mortality; transfer state

###### Live turkeys at hatchery or farm gate, age class declared (`reference_product_handover`)

This is the actual accepted reference product at the declared producer boundary, measured under cp_reference_handover. It is the sole external reference output; instantiate its real identity from the lot, not a broad fixed UUID.

The actual route/state/gate is selected from foreground handover evidence; retain every required qualifier.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `a_outputs` | breeder, hatchery, rearing | Enumerate marketed eggs, poults, older birds, spent breeders and exported manure with handover; reject eggs, shells, mortality and unsold litter are loss/waste. | `fao-leap-poultry-2016` |
| `a_allocation` | independent co-products | Prefer documented physical causality; otherwise declare one mass or economic allocation basis, matching period-specific output masses/prices and disclosing sensitivity. | `fao-leap-poultry-2016` |
| `a_period` | breeder years and cohorts | Link inputs, assets, stock changes, deaths and outputs to breeder year, hatch batch and grow-out cohort; allocate replacements and spent breeders once. | `fao-leap-poultry-2016` |
| `a_shared` | shared buildings, incubators and meters | Attribute by measured use or documented capacity-time across all consuming nodes/periods; sum shares to one original burden. | `fao-leap-poultry-2016` |

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.

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_residual_precedence` | remaining common burden with no specified primary branch | Resolve any study-specific joint-product instruction in this PCR that has no specified primary branch using this precedence; retain an already explicitly prescribed category-specific primary method. First directly assign separable output-specific activities. For the remaining common burden B, use a physical driver d_i only when measured operation or biological-service records demonstrate the causal consumption represented by that driver. A product being weighable, valuable or lower grade alone is insufficient; do not switch arbitrarily between area, time, mass and revenue. For comparable grades receiving the same common handling, measured processed mass is applicable only with the same service demand, state and moisture basis demonstrated. Share a_i=d_i/sum(d_j); B_i=B*a_i. If no defensible causal physical driver exists for that common operation, use gate- and period-matched economic shares a_i=(q_i*p_i)/sum(q_j*p_j), with the complete independently intended output set, compatible quantity/price units, currency, representative prices and values before output-specific downstream processing. Missing price or denominator evidence makes the allocated result incomplete, not a zero-priced product or a single-output system. Report shares summing to one and sensitivity to a material alternative; an alternative is not an interchangeable primary result. Waste, retained residues and internal transfers receive no co-product share, while their attributable production/handling burdens remain with the producing saleable route. Retain unallocated physical quantities and mass balances separately. This branch gives no automatic substitution credit; any separately scoped substitution analysis retains the gross inventory and its actual displaced-function evidence. | `ghg-protocol-product-standard-2011` |

### 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.

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `c_mass` | live birds | heads × representative sampled mass by age/class | count, sample weights, route | kg live output | `mass-balance-identity` |
| `c_hatch` | hatchery | accepted eggs = saleable + non-saleable + unhatched + documented other outcomes in counts | hatch ledger | reconciled hatch count | `mass-balance-identity` |
| `c_cohort` | rearing | opening + receipts − deaths − dispatch = closing heads, with internal transfers separately identified | cohort ledger | reconciled live stock | `mass-balance-identity` |
| `c_manure` | emissions | model CH4, N2O and NH3 by non-overlapping manure volatile-solids and nitrogen pathways and factor tier | VS, N, pathway shares, factors | kg CH4, N2O and NH3 | `ipcc-livestock-2019` |
| `calc_feed_supply_and_intake` | `breeder_feed`; `rearing_feed` | Feed supply used by the represented operation = opening feed stock + receipts + on-site feed entering the operation - closing feed stock - documented unused returns or transfers out. Retain in-boundary spoilage, refusals and discarded leftovers in that supply. Actual intake = that supply - measured uneaten/discarded losses, after matching moisture/DM and period; use intake only for nutrition/metabolism. Opening stock retains its prior burden and is not another purchase. Trace any unused return or transfer and its burden destination; no automatic substitution credit. Attribute production once, through either the purchased-feed dataset or the represented on-site crop/collection node, never both for the same feed. 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 | `fao-feed-loss-accounting-2018` |
| `calc_manure_n2o_coverage` | `breeder_n2o`; `manure_n2o` | 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-livestock-2019`; `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_breeder_manure`; `cp_manure`; 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 |
| --- | --- | --- | --- |
| `q_route` | reference and final output | identify exact day-old/hatchery or older/farm route and only one final gate | dispatch and receipt |
| `q_count_mass` | birds and eggs | retain count, age/class, sample size and sampled mass | scale and count log |
| `q_predecessor` | eggs/poults | trace purchased or integrated prior burden without duplicate transfer | supplier dataset or internal ledger |
| `q_period` | breeders and shared assets | reconcile opening/closing stock, deaths, service period and share | period ledger |
| `q_fate` | waste and co-products | record independently marketed outputs and each residue fate | transfer/treatment record |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `v_route` | all final birds | Reject unidentified age/gate mixtures; route UUID must match exact output, broad reference remains unresolved. | `unsd-cpc-2025` |
| `v_hatch` | hatchery | Reconcile egg input and all hatch outcomes; at most one saleable poult per accepted egg. | `mass-balance-identity` |
| `v_cohort` | rearing/catching | Reconcile poult receipts, mortality, internal standing transfer, final dispatch and live mass. | `mass-balance-identity` |
| `v_attribution` | co-products and shared periods | Require all intended output gates, allocation basis and breeder/cohort period; no double-burden of assets or internal birds. | `fao-leap-poultry-2016` |
| `v_manure` | air emissions | Check substance, air medium, non-overlapping manure pathway, factor tier and time period. | `ipcc-livestock-2019` |
| `v_flow_identity` | water and energy | unresolved Product inputs resolve to verified concrete UUID only from actual water function and energy carrier. |  |
| `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. | `fao-feed-loss-accounting-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-livestock-2019`; `ipcc-managed-soils-2019` |
