Boar Testicular Ultrasound and Semen Production Correlation Data

110 boars were assessed via testicular ultrasonography at 22, 24, and 26 weeks of age to obtain echotexture traits DKL and Tubular Density. 2,498 ejaculates were analyzed for sperm count, motility, and morphology. Carolina L. A. Da Silva published this research dataset on figshare in 2026 under a CC-BY-4.0 license.

Use Cases

• Predicting total sperm cell count based on ultrasound-derived Tubular Density.
• Analyzing correlations between testicular echotexture traits and sperm motility percentages.
• Investigating the relationship between grey pixel count (DKL) and sperm morphology.
• Developing early selection models for boar productivity using ultrasound data from 22 weeks.
• Studying changes in testicular echogenicity during sexual development in boars.

Strengths

• Dataset includes longitudinal ultrasound measurements from 110 boars across three time points.
• Correlations are calculated between ultrasound traits and semen analysis results from 2,498 ejaculates.
• Statistical analysis includes Least Square means corrected for multiple factors like weight, age, and season.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and methodological bias inherent to the specific study design.
