  • Deep Learning Systems for Automatic Egg Grading

    Lilong Chai

    April 27, 2025

    Defective eggs (eggs with abnormal exterior quality and size, Figure 1) can reduce the egg quality/food safety and market value of laying hen production, especially in cage-free houses where floor eggs are more common. To improve egg quality, automated grading and defect detection systems have been developed using machine vision and image processing. Automated egg…

  • A Robotic Machine Vision System for Tracking Dead Chickens

    Lilong Chai

    February 28, 2025

    It’s estimated that approximately 20 million chickens in the U.S. die in commercial poultry houses before reaching market age or arriving at slaughterhouses for various reasons. In commercial broiler or cage-free laying hen houses, thousands of chickens are housed within the same facility in high density. Animal wellbeing monitoring, including daily mortality checks, is typically…

  • Monitoring Perching Behavior of Cage-free Hens with Machine Vision

    Lilong Chai

    January 31, 2025

    Domestic fowl shows the tendon-locking phenomenon, which lets them to express perching behavior (PB) with minimum muscular effort. The domestic hens look for an elevated structure for resting during night as that the jungle fowl, in order to prevent themselves from ground predators. Providing perches in cage-free (CF) housing (Figure 1) offers significant benefits for…

  • Monitoring Poultry Activity Index with Deep Learning

    Lilong Chai

    August 12, 2024

    Animal activities and behaviors provide significant insights into the mental and physical well-being of poultry, serving as a key indicator of their health and subjective states. For instance, predicting indoor particulate matter concentration in poultry houses can be informed by broiler activity and ventilation rates. Additionally, locomotor activity acts as a proxy for the gait…
