Live sheep at farm gate

1. Scope and Applicability

This PCR covers live domestic sheep managed for meat, wool, milk, breeding, replacement, or mixed purposes and transferred alive at the producing farm gate. The managed biological-production boundary includes admitted breeding or replacement stock, mating and gestation where present, lambing, lamb rearing, grazing or housed feeding, animal health, shearing as flock management, water and energy use, manure routing, selection or finishing, live-weight measurement, and transfer of control.

The reference product excludes goats and other ruminants, sheep meat and carcasses, raw milk, greasy wool or fleece as a separately sold reference product, skins, animal-husbandry or veterinary services sold separately, post-farm transport, and animals after slaughterhouse receipt. Extensive grazing or transhumant, mixed, and housed or intensive routes may coexist in one reporting system only when records preserve their separate feed, movement, infrastructure, manure, and emission requirements; otherwise choose one declared route.

The reference product-flow UUID remains blank because no compatible mass-based live-sheep Product flow at the producing farm gate has been confirmed. Independently confirmed Mass property and Mass unit-group support identities are recorded above; they do not establish a product-flow binding. Head count may be retained as an activity datum, but it cannot replace measured live-weight mass.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_live_weight_mass	reference live sheep	Mass	kg	Use live weight measured immediately before ownership or control transfer at the producing farm gate. Record the scale point, fasting or gut-fill convention if applied, and whether mass is individual or lot total.
headcount_to_mass	animal counts, entries, births, deaths, and transfers	Mass	kg	Count records require animal class and measured or sampled mean live weight before conversion to kg; retain count and conversion evidence.
feed_mass_basis	grazed forage, conserved forage, concentrates, by-products, supplements, and milk replacer	Mass	kg dry matter and kg as-fed	Preserve as-fed quantity and measured or supplier dry-matter fraction; do not combine wet and dry feed records without conversion evidence.
water_measurement_basis	supplied drinking and service water	Mass or volume	kg or m3	Record metered or estimated supplied water separately from rainfall and unmanaged surface water; disclose the estimation method when no meter is used.
gas_species_basis	methane and nitrous oxide outputs	Mass of named compound in final exchanges	kg CH4; kg N2O	Retain raw N-basis records; before final normalization convert kg N2O-N to kg N2O by 44/28. Values already expressed as compound mass are not converted again. The final fixed-UUID exchange uses the mass of its named compound, never the N-basis amount. Keep raw species and elemental bases explicit; carbon-equivalent quantities do not replace CH4 mass.
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. Compute normalized amount = attributable amount * declared reference quantity / measured accepted reference-output quantity. Apply normalization once only; never divide an already normalized value again.
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 or replacement sheep admitted to the represented flock, together with purchased feed, forage, water, energy, health products, and other managed inputs crossing the farm boundary.
starting_condition_role	The admitted flock and managed inputs start the foreground managed biological-production responsibility; births, growth, health management, grazing or housing, shearing, manure handling, and selection or finishing remain inside it.
product_classification_scope	Live sheep corresponding to CPC 3.0 02122; milk, wool, manure, meat, skins, and services remain separately classified outputs or activities.
recursive_input_rule	Live sheep admitted from another producer are recorded as upstream live-sheep Product inputs with their own supplier dataset; do not recursively recreate their pre-transfer production inside the receiving farm process.
upstream_dataset_requirement	Require supplier datasets for purchased or transferred live sheep, feed and forage, health products, energy carriers, supplied water, and inbound transport where material; unresolved flow identities remain semantic until a verified concrete UUID is selected.
disclosure	Declare animal classes and purpose, route variant, grazing and housing regime, feed boundary, breeding/replacement treatment, manure pathways, shearing and milk treatment, shared assets and service periods, reporting/cohort period, geography, weighing point, and farm-gate transfer.

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 managed_sheep_production 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.

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.

feed_forage_supply_specific_input	cp_feed_and_grazing	Operation managed_sheep_production: Record each feed source actually entering the flock diet, including grazed forage where its managed production is in scope, conserved forage, concentrates, by-products, supplements, and milk replacer. No generic feed UUID is assigned. Denominator and scope requirements：per kg live sheep at farm gate 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.
flock_health_products_specific_input	cp_health_products	Operation managed_sheep_production: Record actual vaccines, medicines, disinfectants, mineral treatments, and other purchased health products by formulation and use. Veterinary services sold separately are not the reference product. Denominator and scope requirements：per kg live sheep at farm gate Original quantity method: Record product, active ingredient or formulation, dose, treated animal class, date, and discarded quantity; report zero when unused.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_to_reference_live_weight	all inventory rows	normalized amount = period amount / farm-gate transferred live-weight mass. Preserve raw period and animal-class records.	period amount; transferred live-weight mass	amount per kg reference live weight	fao-leap-small-ruminants-2016
reconcile_flock_balance	flock events	opening head + entries + births = closing head + live transfers + live sales + mortalities, with class changes linked rather than treated as new animals.	flock-event records	head-count reconciliation and exceptions	fao-leap-small-ruminants-2016
calculate_feed_dry_matter	feed and forage	dry-matter amount = as-fed amount multiplied by measured or supplier dry-matter fraction; pasture intake uses the declared reviewed estimation method.	as-fed mass; dry-matter fraction; pasture records	kg feed dry matter	fao-leap-small-ruminants-2016
calculate_enteric_methane	enteric methane	Apply the declared IPCC tier or reviewed method by sheep category and period; preserve activity data and factor provenance.	animal category; population or animal-days; feed or gross energy; factors	kg CH4	ipcc-2019-livestock-manure
calculate_manure_emissions	manure methane and direct nitrous oxide	Apply the declared reviewed equations by animal category, excretion and manure pathway. Retain raw N-basis records; before final normalization convert kg N2O-N to kg N2O by 44/28. Values already expressed as compound mass are not converted again. The final fixed-UUID exchange uses the mass of its named compound, never the N-basis amount.	animal records; feed nitrogen or excretion; manure pathway; climate; factors	kg CH4 and kg N2O	ipcc-2019-livestock-manure; fao-leap-nutrient-flows-2018
calculate_transport_service	included inbound road transport	transport service = transported mass in tonnes multiplied by one-way included distance in kilometres.	cargo mass; distance	t*km	fao-leap-small-ruminants-2016
calc_pathway_emissions	managed_sheep_production	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	ipcc-2019-livestock-manure; review-eea-manure-2023; review-ipcc-soils-2019
calc_feed_supply_and_intake	feed_forage_supply	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	manure_direct_n2o_air; review_managed_sheep_production_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	ipcc-2019-livestock-manure; 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_manure_and_emissions; 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

route_specificity	all inputs and outputs	Keep extensive or transhumant, mixed, and housed or intensive route records separate where their feed, movement, infrastructure, manure, or emission requirements differ.	route description, grazing and housing records, aggregation worksheet
temporal_completeness	flock and asset records	Cover all material biological phases and events contributing to the declared output; disclose partial-cycle data and upstream datasets.	flock calendar, event register, replacement and culling records
output_and_loss_completeness	all output categories	Reconcile live sheep, wool, milk, exported manure, mortalities, closing stock, and internal uses; explain every omitted conditional output.	output, transfer, inventory, mortality, and waste records

shared_burden_traceability	shared infrastructure and services	Retain consuming groups, service periods, measurements, allocation driver, and evidence that the burden was counted once.	meters, operating logs, animal-day or live-weight-time worksheet

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_identity	reference output	Reject a dataset that substitutes sheep meat, wool, milk, skin, goat, or a service identity for live sheep, or that omits the farm-gate live-weight basis. A concrete dataset must resolve one compatible platform UUID before publication.	fao-leap-small-ruminants-2016
validate_route_resolution	alternative route variants	Require one declared route or a transparent aggregation of separately recorded routes. Confirm that feed, movement, housing, infrastructure, manure, energy, and emission records match the declared route delta.	fao-leap-small-ruminants-2016
validate_period_linkage	multi-period flock production	Require opening and closing stock, entries, births, transfers, sales, culls, mortalities, and output events to reconcile by class and period; prevent replacement, breeding, asset, or output burdens from being attributed in two periods.	fao-leap-small-ruminants-2016
validate_output_attribution	live sheep and conditional co-products	Require complete intended-output and loss sets, each hand-off, direct partitioning evidence, and one disclosed residual allocation method. Prevent wool, milk, manure, cull stock, or breeding stock from being counted at two hand-offs.	fao-leap-small-ruminants-2016; fao-leap-nutrient-flows-2018
validate_shared_infrastructure	shared housing, fencing, water, handling, shearing, vehicles, and manure systems	Require at least two consuming groups, activities, or periods, a service boundary, a documented attribution driver, and evidence that the same shared burden is not duplicated.	fao-leap-small-ruminants-2016
validate_manure_and_emissions	enteric and manure emission rows	Require animal category, activity data, manure pathway, method tier, factor provenance, gas species and basis, and pathway reconciliation. Reject use of IPCC factors as measured farm inventory amounts.	ipcc-2019-livestock-manure; fao-leap-nutrient-flows-2018
validate_flow_identity_resolution	unresolved water, energy, and transport cards	Require foreground generation to select one verified concrete UUID consistent with the actual product or carrier, property, unit, geography, and use; unresolved cards may not carry a fixed UUID.
v_pathway_emission_coverage	managed_sheep_production	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.	ipcc-2019-livestock-manure; 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.	ipcc-2019-livestock-manure; review-ipcc-soils-2019
