Bed Spacing Density Checker

Audit actual bed inventories against stage-specific caller density limits; signed excess preserves spare capacity and is distinct from DFL forecast bed sizing.

Description

Measured bed density uses actual larvae and usable area.

Measured bed density uses actual larvae and usable area. Signed excess shows spare capacity as well as overage.

Audit actual bed inventories against stage-specific caller density limits; signed excess preserves spare capacity and is distinct from DFL forecast bed sizing.

When to use Bed Spacing Density Checker

Use this tool to audit actual bed inventories against stage-specific caller density limits; signed excess preserves spare capacity and is distinct from DFL forecast bed sizing.

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.

How to use Bed Spacing Density Checker and understand its results

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
Enter bedLarvaCounts, usableBedAreasM2, callerMaximumDensitiesPerM2 using the field table and calculation rules, then run the tool.
Read measuredDensitiesPerM2, densityExcessLarvae, aboveCallerDensityFlags. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
bedLarvaCounts	Bed larva counts	list of number	Required
usableBedAreasM2	Usable bed areas m2	list of number	Required
callerMaximumDensitiesPerM2	Caller maximum densities per m2	list of number	Required

Align nonnegative integer larvae with positive areas and positive density limits. Return local densities, signed excess and flags only for strict overage; equality does not flag.^[1]

Paired lists must be nonempty and have equal lengths.

density = larvae/area; excess larvae = larvae − area × caller maximum density

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
measuredDensitiesPerM2	Measured densities per m2	list of number
densityExcessLarvae	Density excess larvae	list of number
aboveCallerDensityFlags	Above caller density flags	list of number

Limitations and assumptions

Caller limits do not establish optimal welfare, health or production outcomes.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Rearing Bed Area Per 1000 DFLs: Plan stage-specific bed areas and whole trays per observed DFL/egg/hatch/survival scenario; DFL is an inventory label, not a disease-free certification or universal density. For a complementary task, use Tray Stack Gap Height: Calculate equal clear intertray gap after tray thickness and room edge clearances and compare caller minimum; airflow, rack strength and ergonomics are not certified.
