# **Number Cards**

Use Number Cards to check your flock summaries at a glance. They normally use your default Company and the current month through today. Optional Company, Item, Batch, House, and date filters narrow their scope where configured. Dashboard eligibility uses livestock-marked Batches; verify the field before troubleshooting a zero.

## **Survival Percentage**

Shows the operational period survival percentage, combining animal counts rather than averaging Batch percentages. It excludes separately classified culling from deaths. Read the [dedicated survival guide](https://file+.vscode-resource.vscode-cdn.net/home/muchemi/homeland_onja_bench/apps/livestock_management/docs/reporting-and-monitoring/survival-percentage.md) for denominator and unavailable cases.

## **Feed Consumed**

Sums stock quantities from submitted **Feeding / Material Issue** entries linked to eligible livestock Batches, converted to **Kg**. It does not count draft entries or purchases sitting in the feed store. A zero means no matching recorded consumption; an unavailable value can indicate invalid units, inaccessible details, or missing house allocation.



Read this value as kilograms of feed, not currency.

## **Internal Feed Conversion Ratio**

**Feed Conversion Ratio** is kg feed divided by kg live-weight gain between valid measurements. It is a ratio, not a percentage or currency. The shared interval rules are also used by the batch performance report.



For every active Batch/House in scope, the calculation uses the latest two measurements within the selected period. Those measurements must have different timestamps, explicit Company/House/Kg UOM, valid samples and positive average weights. The interval needs positive population, positive biomass gain, and no unsupported population-changing movements. Relevant feed must be posted in the interval. Several eligible house/batch intervals are aggregated as total feed divided by total biomass gain, not an average of ratios.



Example: 100 animals growing from 1.0 to 1.2 kg with 40 kg feed give FCR 2. One Weight Record cannot establish that gain. Missing or invalid intervals return unavailable/N/A with a reason; do not create an invented opening weight to obtain a number.
