Development of a control system for gas concentration and temperature in an animal preference chamber
An enhancement of the environmental control capabilities was planned and executed for an Environmental Preference Chamber (EPC) used for animal behavior testing. A fuzzy logic controller (FLC) was designed and built to control distinct ammonia concentration levels independently in each of the EPC’s …

An investigation of laying hen interactions with ammoniated environments by means of preference testing
… many different housing systems, with potential environmental challenges to efficient production performance and, in extreme cases, animal survival. Thus, controlling the environment in commercial livestock and poultry facilities is important for improving animal welfare and optimal production, …

Systematic evaluation of laying hen exposure to atmospheric ammonia
… short-term high-concentration exposure, and preference/aversion behavior testing. The two exposure studies used a combination of measures, including pathology, immunology, and production. The preference testing was conducted in an environmental preference chamber that allowed the hens to move …
