Make the record useful in daily work.
A single weight is a snapshot. Repeated measurements, taken with a consistent method and connected to age, litter and health context, are far more useful for operational decisions.
- Use a consistent weighing routine
- Keep date, age and animal identity together
- Review trends instead of one reading
- Investigate unexpected changes with husbandry context
Start with the date and keep the outcome.
Use a consistent process, then record what actually happened. Over time, those connected records make planning more reliable than memory or disconnected spreadsheets.
