Cocoon FCR Leaf Conversion
Compute net consumed fresh/dry leaf per fresh cocoon harvest after separately assayed leftovers; unlike biomass-gain fish FCR, cocoon harvest is an explicitly different denominator.
Description
Leaf conversion uses net consumed feed rather than offered feed.
Leaf conversion uses net consumed feed rather than offered feed. Fresh and dry ratios must retain their own mass bases.
Compute net consumed fresh/dry leaf per fresh cocoon harvest after separately assayed leftovers; unlike biomass-gain fish FCR, cocoon harvest is an explicitly different denominator.
When to use Cocoon FCR Leaf Conversion
Use this tool to compute net consumed fresh/dry leaf per fresh cocoon harvest after separately assayed leftovers; unlike biomass-gain fish FCR, cocoon harvest is an explicitly different denominator.
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 Cocoon FCR Leaf Conversion 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 leafOfferedKg, uneatenLeafKg, offeredLeafDryMatterFraction, uneatenLeafDryMatterFraction, freshCocoonYieldKg using the field table and calculation rules, then run the tool.
- Read consumedFreshLeafKg, consumedDryLeafKg, freshLeafPerFreshCocoonKg, dryLeafPerFreshCocoonKg. 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 |
|---|---|---|---|
| leafOfferedKg | Leaf offered kg | number | Required |
| uneatenLeafKg | Uneaten leaf kg | number | Required |
| offeredLeafDryMatterFraction | Offered leaf dry matter fraction | number | Required |
| uneatenLeafDryMatterFraction | Uneaten leaf dry matter fraction | number | Required |
| freshCocoonYieldKg | Fresh cocoon yield kg | number | Required |
Use positive fresh cocoon yield, nonnegative feed masses and dry fractions in [0,1]. Require nonnegative fresh and dry consumption, then divide both by fresh cocoon harvest.1
consumed leaf = offered − uneaten; conversion = consumed leaf/fresh cocoon kg Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| consumedFreshLeafKg | Consumed fresh leaf kg | number |
| consumedDryLeafKg | Consumed dry leaf kg | number |
| freshLeafPerFreshCocoonKg | Fresh leaf per fresh cocoon kg | number |
| dryLeafPerFreshCocoonKg | Dry leaf per fresh cocoon kg | number |

}Limitations and assumptions
The denominator is harvest mass, not biomass gain; no universal FCR comparison is implied.
Numbers and computed results must be finite; overflow produces an error. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Mulberry Leaf Yield Per Hectare Year: Normalize repeated mulberry harvests on fresh/dry bases and explicitly annualize the observation span; constant productivity annualization is a scenario, not a seasonal yield forecast. For a complementary task, use Castor Eri Leaf Consumption Cycle: Plan eri castor-leaf demand from stage duration, expected survival and measured per-larva consumption plus leftovers; distinct from observed leaf/cocoon harvest FCR.
