Pig breeding and record keeping
Being organised is essential for timing insemination accurately. Use this information to develop your own records for effective service routines.
Why are records so important?
Setting up and following an effective heat detection and service plan for your farm helps you:
- detect the signs of heat accurately
- schedule insemination at the optimum times
This is essential for optimising breeding performance and achieving the best results.
Review and adjust the routine periodically and develop an effective routine that is based on current best practice and information recorded on your farm. It is also important to make allowances for variations.
What should be recorded
Make sure you record this information for each female:
- Tag number (weaning to oestrus interval)
- Date and time of proestrus
- Date, time and duration of oestrus
- Date and time of first standing heat
- Date and time of all inseminations
- Projected and actual return dates
- Any other observations
Include details such as:
- Number of days between weaning and oestrus
- Oestrus duration
- Variations in the number of days between weaning and oestrus, and oestrus duration
- Seasonal changes (such as increased returns or longer days to service)
- Weaning day
- Weaning to service interval for your breeding herd (day of the week your sows exhibit first standing heat)
- Duration of heat

Making records easy to follow and review
Clear records and coloured marks make it easy to know what is happening with each female and what the next step needs to be.
Use different coloured spray markers and/or the position, shape or number of marks, to clearly show the status of each female.
Keep everyone informed
- Provide training for relevant staff
- A step-by-step manual can help everyone follow the routine on the farm
- Use record books to help ensure key information follows the routine on the farm
Use the information
- Review recorded information regularly to determine any trends for your farm or for individual females
- Determine if your herd is generally a 2- or 3-day standing heat herd
- Tailor the insemination routine accordingly
