Non-bovine semen for breeding

1. Scope and Applicability

This PCR covers usable breeding semen from animals other than bovines, including sheep and goats, at collection/processing-centre release. Fresh, chilled and frozen states require separate lot records. Bovine semen (CPC 02411), embryos, live donors, insemination services and downstream distribution are excluded. Species-specific veterinary and trade measures apply only where relevant; they are not universal LCA factors.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
accepted_count	reference output	accepted count	dose	Count only released doses passing the documented species-specific acceptance specification.
liquid_balance	collected semen and diluent	calibrated volume and concentration	mL; sperm/mL	Reconcile raw volume, preparation medium, rejected material and filled dose count; volume alone does not establish dose equivalence.
state_partition	final product	accepted count by state	dose	Fresh, chilled and frozen denominators remain separate unless a documented comparison conversion is supplied.
period_link	donor and shared services	duration and accepted output	donor-day; dose	Link dated inputs, events and asset use to the donor and batch periods without duplicate annualization.
accepted_item_count	reference product and its output card	Number of items 01846770-4cfe-4a25-8ad9-919d8d378345	item	The machine unit item is the local representation of the confirmed unit-group reference unit Item(s), with multiplier 1. One item means one quality-accepted breeding dose of the declared species, state, grade and release specification. Preserve native dose counts in collection records. This count representation does not equate containers, volume, sperm count, oocytes or treatment attempts to accepted goods, and does not establish equivalence across species, states or dose specifications.
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.

Released breeding dose (released_dose)

The sole reference product is quality-accepted non-bovine breeding semen at centre handover.

Raw reference-output records: Count accepted units by species, grade and final state and link volume and sperm count. Preserve the measured accepted lot quantity and every required qualifier. The amount below is the normalized reference exchange, not an assertion that a physical lot contains only one unit.

The machine unit item is the local representation of the confirmed unit-group reference unit Item(s), with multiplier 1. One item means one quality-accepted breeding dose of the declared species, state, grade and release specification. Preserve native dose counts in collection records. This count representation does not equate containers, volume, sperm count, oocytes or treatment attempts to accepted goods, and does not establish equivalence across species, states or dose specifications.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
period_attribution	donor	Link feed, water, health, manure, collection and accepted lots to dated donor phases; record replacement and cull events. Never charge a donor-period twice.	review-fao-pig-lca-2018
shared_service	housing, collection apparatus, lab and cooling	Enumerate consumers and service periods, then assign each burden once by measured occupancy, usage time or another justified causal service basis.	review-fao-pig-lca-2018
quality_outputs	grading and filling	Downgraded material is a co-product only with independent legal handover; otherwise treat rejects as waste. Disclose any causal or physical/economic allocation decision and sensitivity.	review-fao-pig-lca-2018
mixed_state	fresh, chilled and frozen	Assign common donor/collection burden to actual accepted lots using documented causal service or counts; preserve state-specific energy, cryogen and loss for applicable lots only.	review-fao-pig-lca-2018
allocation_method_basis	Residual joint burdens and shared service	Apply the general LCA hierarchy: examine subdivision or an appropriately justified system expansion before residual allocation; then prefer a supported physical causal relationship, and justify an economic basis when physical attribution is not established. The donor-day, occupancy or throughput driver is a PCR modelling choice requiring case-specific evidence and sensitivity, not a requirement of sanitary guidance. Include failed attempts and losses in the service period; do not select only successful outputs or introduce hypothetical substitution credits.	review-fao-pig-lca-2018

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
feed_specific_input	cp_donor	Operation donor: Record feed supply, measured intake and losses for eligible donor maintenance over the recorded period; intake is not the upstream feed inventory. Denominator and scope requirements：per linked accepted dose Raw quantity and calculation requirements: Use separate feed-supply, intake and loss ledgers under calc_feed_supply_and_intake. The quantity carrying feed-production burden includes in-boundary refusals, spoilage and uneaten feed; it is not reduced to animal intake. Retain source, species/cohort, phase and original mass/moisture basis. Calculate the final contribution with inventory_reference_normalization and stage_throughput_linkage exactly once. Original collection denominator kind: reference_flow. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using reconciled feed-supply records that retain in-boundary losses and their production burden.
packaging_specific_input	cp_release	Operation release: Only centre-issued protective packaging is included; reusable containers are apportioned over actual reuse cycles. Denominator and scope requirements：per released dose Raw quantity and calculation requirements: Weigh issued packaging and attribute reusable service once. 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.

Material and service identification requirements

Identify each actual material or independently supplied service from supplier and activity records; record composition/specification, quantity, unit, node and period separately. Add one concrete exchange per identity before dataset completion; these requirements are not a single exchange. Reconcile with existing cards and inclusive services to avoid duplication. Allocate reusable assets over evidenced use and preserve physical quantities; normalize once to the matched final reference output. Missing identity or use evidence is a completeness gap, not zero use. Conditional examples below are not an exhaustive bill of materials and do not prescribe use or amounts.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
dose_yield	collection through release	Reconcile raw volume and concentration with graded states, prepared bulk, fill and release counts; accepted released doses divided by linked donor period.	donor, lot, liquid, quality and dose records	accepted yield and loss ledger	woah-semen-hygiene-2024
service_share	donor and shared assets	Period burden times evidenced service share divided by accepted linked dose count; disclose unproductive periods and reject zero denominators.	dated inputs, service duration, linked doses	burden per dose	woah-semen-hygiene-2024
state_burden	preservation	State-specific metered power, cryogen and rejects divided only by accepted doses in that state.	lot state, meter, supply and acceptance	fresh, chilled or frozen inventory	fao-cryoconservation-2012
calc_pathway_emissions	donor	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	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	review-fao-pig-lca-2018
calc_manure_n2o_coverage	review_donor_direct_n2o; review_donor_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

balance	graded-to-release chain	Reconcile liquid and discrete units across accepted, downgraded, rejected and lost states within documented measurement tolerances.	woah-semen-hygiene-2024
branch	final state	Require one fresh/chilled/frozen final state per lot; chilled/frozen lots need observed intervention and duration, never bovine default factors.	fao-cryoconservation-2012
no_double_count	donor and assets	Dated donor phases and housing, laboratory, collection and refrigeration shares must charge each service once per period.	woah-semen-hygiene-2024
gate_quality	release	Require donor species, count, volume, sperm specification and quality release; reject insemination/distribution activity.	woah-semen-hygiene-2024
v_pathway_emission_coverage	donor	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.	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.	review-ipcc-livestock-2019; review-ipcc-soils-2019
