Pig production is becoming increasingly data-driven. Producers need reliable information about pig growth, feed efficiency and overall performance in order to react quickly when something changes in the barn.
However, manual weighing is still common in many pig farms. This approach is time-consuming, stressful for animals and provides only limited data points.
A modern pig weighing system based on camera technology makes it possible to monitor pig growth automatically and continuously – without handling the animals.
Growth performance is one of the most important indicators in pig production. Even small deviations in growth rate can significantly affect feed conversion, slaughter timing and overall profitability.
When pig weight is monitored continuously, producers can:
• Detect deviations in growth early
• Evaluate the effect of feed changes
• Identify health or management issues sooner
• Compare batches and optimize production strategies
Automated weighing systems make this possible by collecting weight data continuously rather than relying on occasional manual measurements.
Many producers search for tools such as a pig weight calculator to estimate pig weight based on measurements or formulas.
While these tools can provide rough estimates, they require manual input and only deliver occasional snapshots of the pigs’ weight.
Modern technology now allows pig weight to be estimated automatically using camera-based systems. Instead of calculating weight from measurements, a camera can capture images of pigs and estimate their weight using advanced algorithms.
This approach provides continuous insight into pig growth with much more accuracy than manual weighing.
A pig weighing system using a 3D camera works by installing a camera above the pen, typically near the feeder where pigs pass regularly.
The camera captures images of the pigs and analyzes them to calculate the average weight in the pen automatically.
The iDOL 65 Pig Weighing Camera is an example of such a system.
The camera captures images frequently and calculates the average pig weight in the pen every hour, based on thousands of measurements collected throughout the day.
This enables continuous monitoring of growth and production performance.
With a pig camera weighing system, the average weight is calculated using images captured every few seconds. These images are analyzed to estimate the pigs’ weight and determine growth trends over time.
For example, a system like the iDOL 65 captures images every 10 seconds and calculates the average weight in the pen using thousands of weighings collected over a 24-hour period.
The system can deliver data such as:
• Average pig weight in the pen
• Standard deviation of pig weights
• Minimum and maximum estimated weight
• Number of weighings per hour or day
This information provides a continuous overview of growth performance.
Traditional pig weighers measure individual animals occasionally. A camera-based pig weigher instead provides a continuous stream of data that can be used to monitor the entire pen.
This makes it possible to:
• Track weight gain over time
• Compare growth curves with expected standards
• Evaluate the effect of feed changes
• Detect potential health problems earlier
Weight data is often combined with other barn data such as feed consumption, water consumption and climate conditions to better understand overall production performance.
Technologies such as the iDOL 65 pig weighing camera represent a new generation of pig weighing systems.
Mounted above the pen, the camera continuously captures images of pigs and estimates their weight using advanced algorithms. The system provides hourly updates on the average weight in the pen and other key growth indicators.
By combining automated weight monitoring with other production data, producers and technology providers can gain a deeper understanding of how pigs grow and how production can be optimized.
