Make the record useful in daily work.
Litter records turn an individual kindling event into useful breeding evidence. Keep the litter connected to both parents and update the facts as they happen rather than reconstructing them later.
- Actual kindling date
- Born alive and losses recorded separately
- Parentage and litter identity
- Weights, observations and survival to weaning
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.
