Detecting Broiler Chickens with an Innovated Deep Learning Model

Introduction For commercial broiler production, about 20,000 – 30,000 birds are raised in each confined house, which has caused growing public concerns on animal welfare. Currently, daily evaluation of broiler wellbeing and growth is conducted manually, which is labor intensive and subjective to human errors. Therefore, there is a need for an automatic tool to […]

Cage-Free Hens’ Mislaying Behavior Detection with Deep Learning

Introduction The laying hen industry is shifting from conventional caged to cage-free (CF) housing due to various welfare concerns and public demand to improve poultry behavior and welfare. The CF housing can improve welfare by providing more space and chances to perform natural behaviors, but there are some serious downsides to bird welfare and problematic […]

Monitoring Spatial Distribution of Laying Hens with Deep Learning

Introduction The spatial distribution of laying hens in cage-free houses is an indicator of flock’s health and welfare. While larger space allows chickens to perform more natural behaviors such as dustbathing, foraging, and perching in cage-free houses, an inherent challenge is evaluating chickens’ spatial distribution (e.g., real-time birds’ number on…

Dust Generations, Impacts, and Control Strategies in Poultry Houses

Introduction Animal feeding operations are important sources of air pollutant emissions into the environment. The primary air emissions include particulate matter (PM) and other gases like greenhouse gases and ammonia (NH3), as these gases pose a high potential risk to air quality, public and animal health, and climate change. Among…

Controlling Ammonia Emissions in Poultry Houses

Ammonia Issues in Poultry Houses Confined animal feeding operations are the main sources of air pollutants such as ammonia (NH3) and greenhouse gases. Among air pollutants, NH3 is one of the most concerned gasses in terms of air quality, environmental impacts, and manure nutrient losses. It is recommended that NH3…

A Precision Method for Tracking Cage-free Hens on the Floor

Daily routine evaluation of chickens (e.g., broilers and layers) are critical for maintaining animals’ health and welfare in commercial poultry houses. For laying hen production, it is becoming more challenging under cage–free production systems (Figure 1) as compare to conventional caged hens (Figure 2) because birds have freedoms to move…

Robots for Precision Poultry and Egg Production

Broiler production management with robots

Currently, the United States is the world’s largest broiler producer with the annual sales of $40 billion. Modern broiler production is facing emerging challenges of animal health, food safety, environmental impact, and increasing concern from the general public on animal welfare. Fast growth rate and…
