Poultry locomotion is an important indicator of animal health, welfare, and productivity. Traditional methodologies such as manual observation or the use of wearable devices, encounter significant challenges, including potential stress induction and behavioral alteration in animals. For instance, locomotion speed can be used to predict poultry gait score (an indicator of animal walking status) or…

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…

Broiler body weight monitoring is critical for evaluating the growth and performance of a flock. The obtained bodyweight and uniformity of the flock are indicators of daily growth rate, feed-to-meat conversion ratio, health conditions, and marketing day prediction. The traditional protocol is to manually sample and weigh a certain ratio of a flock one by…

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 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…

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…
