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…

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 perches or in nesting boxes).…

Introduction While CF house allows hens to perform more natural behaviors (e.g., dust bathing, perching and foraging on the litter floor), a particular challenge is floor eggs (i.e., mislaid eggs on litter floor). Floor eggs have high chances of contamination. The manual collection of eggs is laborious and time-consuming. Delayed floor egg collection may lead…

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 concentrations in the poultry house…

US Egg production is transitioning from conventional cage to cage-free system. While cage-free system allows birds to perform natural behaviors such as dustbathing, foraging, and perching, an inherent challenge is feather pecking (FP, Figure 1). Pecking is one of the primary welfare issues in commercial cage-free hen houses as that can seriously reduce the well-being…

Broiler production and issues: The world’s population is expected to reach 9.5 billion by 2050 and the requirement for animal products (e.g., meat, eggs, and milk) will be increased by 70% as compared to 2005 levels. As indicated, it is challenging to improve animal production efficiency and product quality under limited natural resources (e.g., fresh…

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 in a larger space and…

Introduction Heat stress is the primary concern for laying hen production in the summer as heat waves may significantly increase flock mortality and reduce egg production in laying hen houses. Mechanical ventilation and cooling cell are popular cooling methods used in the US South such as Georgia. However, most of layer farms in the US…
