Area of Science:

  • * Agricultural Science
  • * Biomedical Engineering
  • * Veterinary Medicine

Background:

  • * Fertilized eggs are crucial for producing egg-based vaccines.
  • * Accurate and efficient detection of unfertilized or dead-in-shell eggs is vital for vaccine yield and safety.
  • * Existing methods may be time-consuming or destructive, impacting production efficiency.

Discussion:

  • * Image processing and spectral analysis identified significant changes in fertilized eggs around the 580-nm band.
  • * A detection device utilizing a 590-nm LED and RGB color space analysis was developed.
  • * Receiver operating characteristic (ROC) curve analysis optimized classification parameters.

Key Insights:

  • * The developed device accurately classifies unfertilized and dead-in-shell eggs.
  • * By the ninth day, detection accuracy and sensitivity reached 100% with a Youden's index of 1.
  • * The system demonstrated high performance, achieving 98% accuracy on day seven.

Outlook:

  • * The technology shows commercial applicability for industrial-scale vaccine production.
  • * High-throughput detection (five eggs per second) supports efficient quality control.
  • * Further refinement could enhance early-stage detection and broaden applications in poultry industries.
