Electrostatic particle ionization technology for air quality management in poultry houses

In the USA, cage-free (CF) housing systems have gained popularity as an ethical and humane poultry farming method. However, the concentration of air pollutants inside CF housing, particularly regarding dust or particulate matter (PM), poses a major concern on animals and their caretakers. These air pollutants can threaten bird health and worker safety. Various studies […]

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…
