Fresh in-shell hatching eggs from birds other than hens

1. Scope and Applicability

This PCR covers fresh intact shell-on eggs of birds other than hens, selected and handed over for hatching. Include managed breeder production, separate collection, selection by hatching suitability and producer-side protective holding/presentation when actually performed. Record species, strain, count, measured shell-on mass, quality evidence and actual gate. A hatching-purpose label does not prove fertility or hatchability. Exclude hens' eggs, non-hatching eggs as the reference, broken or processed eggs, downstream incubation and hatchlings. A vertically integrated hatchery must separate egg and bird product boundaries.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.agriculture-forestry-and-fishery-products.live-animals-and-animal-products-excluding-meat.eggs-from-other-birds-in-shell-fresh-for-hatching
classification_refs	cpc:3.0:02321
covered_products	Fresh shell-on non-hen bird eggs selected for hatching at actual producer handover
excluded_products	Hen eggs; non-hatching eggs as reference; processed or broken eggs; incubated eggs after the egg gate; hatchlings
representative_product	Species- and lot-qualified fresh hatching-egg lot at the producer gate
production_route	Managed breeder laying is the parent activity. Species/housing alternatives are separate routes only when they change feed, water, nesting, manure, collection, holding or acceptance inventory/validation; separate measured cohorts may coexist, but cannot be averaged silently.
market_state	Fresh, shell-on, hatching-selected, with producer-controlled holding and package disclosed

3. Reference Flow

Field	Value
What	Intact fresh shell eggs of birds other than hens accepted for hatching at declared producer handover
How much	1 kg measured shell-on egg mass, with egg count and measured lot mean mass retained
How well	Disclose species/strain, shell integrity, grade, collection/holding time and conditions, and any actual fertility or viability tests; do not infer hatchability
How long or cycle	Declared breeder-flock productive and egg collection/holding periods, including replacement cohort
reference_flow_link	reference_product_handover

Field	Value
Reference amount	1
Reference product flow	Fresh in-shell hatching eggs of birds other than hens
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	species/strain; flock/cohort; actual producer gate; egg count and kg; shell grade; hatching acceptance/test evidence; collection/holding period and conditions; rejected and downgraded destinations; package reuse

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.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
egg_count_mass	final and internal egg lots	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg and count	Measure shell-on mass and count by lot; convert count through measured lot mean mass, never universal cross-species weight.
egg_balance_unit	egg state transfers	Mass	kg shell-on	Reconcile collected, selected, downgraded, rejected, stored and dispatched mass with measured stock change.
service_period	breeders and shared inputs	Carrier-specific property	kg, L, MJ, kWh	Link each input, asset and output to the flock or egg period before reference normalization.
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	Purchased breeder birds, feed, water, energy and package materials enter at documented farm receipt; home-produced inputs require separate traced foreground.
starting_condition_role	Incoming breeder stock before the measured productive flock period.
product_classification_scope	CPC 02321 identifies the accepted fresh shell-on non-hen hatching eggs, not unsorted internal eggs or a separately sold non-hatching grade.
recursive_input_rule	Purchased same-category hatching eggs used to establish breeders are upstream inputs at receipt; do not credit them against resulting eggs.
upstream_dataset_requirement	Trace breeders, feed, energy, water and packaging upstream; farm-only records are not cradle-to-gate.
disclosure	Species/route, flock and egg periods, gate, count/mass, quality tests, collection and holding conditions, losses, co-product handovers and shared-asset attribution.

Boundary Rules

rule_id	Applies to	Rule	source_ids
producer_gate	all routes	Include breeder laying, independent collection, grading and producer-side protection up to egg handover; exclude incubation, hatchling production and post-gate distribution.	fao-goose-production
species_delta	alternative breeder routes	Record parent managed production plus evidenced changes in inventory, collection, holding or acceptance; chicken storage or hatchability assumptions are not transferable to other birds.	fao-goose-production; fao-animal-genetic-resources
grade_state	selected eggs	Hatching use requires documented lot selection; intended use is not proof of fertility or realized hatchability.	fao-goose-production
handoff_once	egg states	Laid, collected, graded and presented states of one lot reconcile as transfers, not repeated independent products.	fao-goose-production
shared_boundary	house, collection room, grader and reusable trays	Identify consuming nodes and service periods; count each shared burden once with a causal driver.	fao-animal-genetic-resources
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.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference

Manure biogenic methane to air (review_breeder_laying_manure_ch4)

Calculate actual atmospheric release by manure system, climate, residence time and volatile-solids activity. Reconcile captured, destroyed or oxidised methane; produced methane is not automatically emitted methane. Applies only to the operated breeder_laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete. Missing evidence is not zero or not_applicable. A verified substance/origin/compartment UUID is still required for a final bound exchange.

Direct manure nitrous oxide to air (review_breeder_laying_direct_n2o)

Use the actual manure-management nitrogen pathway. Keep storage/treatment distinct from field application and grazing deposition, which require a managed-soil method and an explicitly assigned inventory responsibility. Applies only to the operated breeder_laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete.

Calculate attributable indirect N2O from documented manure N volatilisation/deposition and leaching/runoff pathways where applicable. Keep separate from direct N2O and reconcile any nitrogen-fate calculation already included downstream or in the chosen background/impact model. Applies only to the operated breeder_laying node; preserve its existing route and period conditions. A dataset must resolve actual activity, method applicability and an evidence-based range or physical bound for this pathway before treating the inventory as complete.

Manure ammonia to air (review_breeder_laying_nh3)

Use actual species, housing/storage conditions and a justified nitrogen-flow method. Track total N and ammoniacal N by stage; a generic volatilised-N estimate is not automatically NH3 because it may include other nitrogen species. Applies only to the operated breeder_laying node; preserve its existing route and period conditions.

Selected hatching-grade eggs (selected_eggs)

Accepted fresh shell eggs pass to protection or direct handover, not another sale.

Denominator and scope requirements：per kg accepted fresh shell-on hatching eggs

Raw quantity and calculation requirements: Record accepted count and measured mass by species and grade. Original collection denominator kind: reference_flow.

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.

Fresh shell-on hatching eggs at matching farm gate (farm_gate_hatching_eggs)

Fixed identity only for matching other-bird hatching eggs at farm gate; other gates remain unresolved.

Denominator and scope requirements：per kg accepted fresh shell-on hatching eggs

Raw quantity and calculation requirements: Record measured accepted shell-on mass and count at matching gate. Original collection denominator kind: reference_flow.

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.

Inputs

Product flows

Fresh in-shell hatching eggs of birds other than hens for actual producer-handover linkage (reference_handover_input)

This input matches the accepted goods represented by selected_eggs, farm_gate_hatching_eggs 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: selected_eggs, farm_gate_hatching_eggs

Required product-instance qualifiers: species/strain; flock/cohort; actual producer gate; egg count and kg; shell grade; hatching acceptance/test evidence; collection/holding period and conditions; rejected and downgraded destinations; package reuse

Fresh in-shell hatching eggs of birds other than hens (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
output_partition	breeder flock and grading	Enumerate separately handed-over hatching eggs, safely marketed non-hatching eggs, spent breeders and sold manure. Internal states and waste are not co-products. Record each actual gate, mass and period.	fao-goose-production
causal_attribution	joint breeder burden	Attribute separable grading and presentation to the causing output. For inseparable flock burden, document a consistent measured driver and sensitivity to an alternative; no universal mass/economic ratio is imposed.	fao-animal-genetic-resources
period_attribution	flock years and egg lots	Link replacement, laying, collection, assets and losses to actual service/production periods; no assumed universal flock life or double attribution at replacement/exit.	fao-animal-genetic-resources
shared_asset_attribution	house, collection room, grader and trays	List breeder, collection, grading and presentation consumers and service periods; use observed service, throughput or reuse trips to charge each asset only once.	fao-animal-genetic-resources

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=Ba_i. If no defensible causal physical driver exists for that common operation, use gate- and period-matched economic shares a_i=(q_ip_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

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
egg_packaging_specific_input	cp_handover	Operation egg_presentation: Record new/reused materials and trips; post-gate distribution package is outside. Denominator and scope requirements：per kg accepted fresh shell-on hatching eggs Raw quantity and calculation requirements: Record new inputs, losses and reuse-cycle share. Original collection denominator kind: reference_flow. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.
hold_energy_specific_input	cp_handover	Operation egg_presentation: Only pre-gate protection energy, never downstream incubator heat. Denominator and scope requirements：per kg accepted fresh shell-on hatching eggs Raw quantity and calculation requirements: Meter carrier and period before handover. Original collection denominator kind: reference_flow. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
count_to_mass	egg lots	If individual mass is unavailable, sampled shell-on kg divided by sample count gives lot mean mass; multiply by full lot count. Keep species, grade and sample size.	sample kg, sample count, full count	shell-on kg of actual lot	fao-goose-production
egg_balance	collection through handover	Opening stock + laid/collected input = accepted output + independently downgraded + waste + closing stock, with internal transfers counted once.	mass/count by lot and state	mass-balance residual	fao-goose-production
reference_normalization	all cards	Divide attributed foreground amount by measured accepted kg at declared gate; retain independent output handovers.	attributed amount, accepted kg	amount per kg reference	fao-goose-production
calc_pathway_emissions	breeder_laying	Use species- and management-compatible methods and retain disaggregated pathway totals. Convert N2O-N to N2O by 44/28 and NH3-N to NH3 by 17/14 exactly once; already molecular masses are not reconverted. Check methane against the documented available-carbon/methane-potential balance and nitrogen losses against each stage's available N. Indirect formation from previously volatilised N is a downstream transformation, not a second source-stage N loss. Attribute and normalize once; do not duplicate linked treatment or fate-model emissions. Use matched raw-period quantities before allocation for physical screens: CH4 mass × 12/16 must not exceed the carbon available to the represented pathway; source-stage NH3 mass × 14/17 plus direct N2O mass × 28/44 and other source N losses must not exceed that stage's available N, after accounting for stocks and transfers. Bound each indirect N2O-N calculation by its documented volatilised or leached N precursor, not by subtracting that downstream transformation again from the source ledger. These are conservation checks, not emission factors or an empirical per-product range.	cp_pathway_emissions	kg named compound per final reference flow	review-ipcc-livestock-2019; review-eea-manure-2023; review-ipcc-soils-2019
calc_feed_supply_and_intake	breeder_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	review_breeder_laying_direct_n2o; review_breeder_laying_indirect_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	review-ipcc-livestock-2019; review-ipcc-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_pathway_emissions; 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
species_identity	all lots	Trace species/strain, flock and hatching-use acceptance; do not combine species in an undisclosed reference.	flock and grade records

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_identity	final product	Reject hen, non-hatching, shell-less, post-incubation or hatchling flow as this reference; require species, fresh shell state, hatching use and actual gate.	fao-goose-production
validate_balance	all egg nodes	Reconcile count and mass through laid, collected, selected, downgraded, rejected and handed-over states with stock/loss; reject unexplained duplicate outputs.	fao-goose-production
validate_route	alternatives	Require managed parent, real inventory/measurement/validation delta and separately measured cohort; a route label alone is insufficient.	fao-animal-genetic-resources
validate_attribution	outputs, periods and assets	Require handovers, causal allocation driver, consumers and service periods; reject duplicate shared or multi-period burden.	fao-animal-genetic-resources
validate_binding	exchange projection	Resolve each unresolved/unresolved card to a single verified state, gate, property and destination UUID before exchange publication.	fao-goose-production
v_pathway_emission_coverage	breeder_laying	Require a pathway coverage ledger for enteric CH4 where biologically applicable, manure CH4, direct/indirect N2O, NH3 and relevant field emissions. Every pathway needs a measured/calculated value, a named linked process with matching coverage, or supported inapplicability; absent data cannot become zero. Keep wild life before capture outside managed husbandry, assess actual managed holding separately, and retain species-specific evidence.	review-ipcc-livestock-2019; review-ipcc-soils-2019; review-eea-manure-2023
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.	review-ipcc-livestock-2019; review-ipcc-soils-2019

10. Published Dataset Profile

Field	Value
dataset_role	Foreground production package for fresh non-hen shell-on hatching eggs at declared producer gate.
downstream_use	May inform secondary_dataset or background_dataset process and lifecycle-model projections only after concrete identity review.
allowed_use	Species-, lot-, gate- and period-qualified shell-on kg results with hatching-selection evidence.
excluded_use	Inferring hatchlings or hatchability from kg; substituting hen/table eggs; counting hatchery incubation or distribution as farm production.
