Swedish Pig Farms: Welfare and Environmental Data for Automatic Sorting Systems

Seven Swedish farms housing 155–460 finishing pigs provided data on environmental conditions and animal welfare indicators collected at two time points. The study includes CO₂ levels from 597 to 2806 ppm, ammonia from 0.38 to 18 ppm, and tail lesion prevalence ranging from 0% to 82%. Author E. Karlsson published the dataset on figshare under a CC-BY-4.0 license.

Use Cases

• Analyzing correlations between pen design and environmental gas levels based on CO₂ and NH₃ concentration data.
• Modeling changes in animal welfare indicators over time based on skin lesion and manure soiling data collected at early and late production stages.
• Comparing farm management practices and their outcomes based on thematic interview data regarding 'Levers' and 'Barriers'.
• Assessing the impact of automatic sorting systems on pig behavior and health based on tail posture and lesion prevalence metrics.

Strengths

• Includes quantitative environmental measurements (CO₂, NH₃, temperature) from seven farms.
• Contains animal-based welfare indicators (skin lesions, manure soiling, tail lesions) with reported prevalence ranges.
• Combines quantitative sensor data with qualitative thematic analysis from farmer interviews.
• Data collected at two distinct time points (early and late in a production batch) allows for longitudinal analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (291.2 KB), indicating limited scope and sample size.
