“…The building analyzed in the present work is one of the commercial broiler buildings studied in [3], in which the authors carried out an experimental work measuring the NH3, N2O, CO2 and CH4 concentration. The commercial broiler farm is located in Figueira da Foz, a small coastal town in center Portugal.…”

“…The experimental values used in the present study were those measure by [3]. These values will be used to assess the numerical method, by comparing the NH3 concentration values measured at four different locations, and for 6 different situations (2 summer period, 2 winter period and 2 for mid-season period).…”

In the present study, a numerical model was developed to predict the flow pattern inside a broiler building. The model intends to predict the velocities fields inside the domain and ammonia (NH3) emitted or released by litter from poultry housing. The numerical model developed in Computational Fluid Dynamics (CFD) commercial code, intends to represent a commercial broiler building, and intends to simulate the 3D and heat transfer, in steady state flow. The evaporative cooling pads were also included in the model. The validation of the model was based in experimental measurements obtained in previous studies. The simulations were focused on Summer, Winter and also Mid-Season situation. The numerical results of NH3 concentration were compared with the experimental measurements, and a quite good agreement was verified. The numerical results allowed the characterization of: the inside flow pattern developed for the summer and winter situation; the inside NH3 distribution, and the velocity field distribution inside the broiler building. It was found that NH3 concentration increases along the tunnel, especially in low flow rate imposed from the exhaust fan. Also, it was verified that the low velocities inside domain are no sufficient to remove the gaseous pollutants.

“…During the short-term breeding experiment under different light colors, the breeding chamber was well-ventilated and there was almost no anaerobic environment on the manure surface, resulting in almost no generation and emission of N 2 O. According to existing studies [37] , there was a certain difference in the N 2 O emission results during broiler production.…”

Refined management is an inevitable trend in the development of livestock husbandry. Accurate acquisition of breeding environment parameters is beneficial to improve breeding efficiency while reducing environmental pollution. Light is an important breeding environmental factor during broiler breeding. In this study, a short-term broiler breeding experiment was conducted with different light color illumination environments in a digital breeding chamber under lab conditions. According to experimental results, the Red Light (RL) group was conducive to the growth of broilers at 30 d of age with low NH 3 emission concentration; the Green Light (GL) group inhibited the broiler growth; the Yellow Light (YL) group showed the highest average emission concentration of NH 3 and lowest daily average emission concentration of CO 2 . According to the analysis of moisture content, pH value, and C/N in the broiler manure, it can be concluded that the physical and chemical properties of broiler defecation quantities were different under various light color illuminations, resulting in the difference in broiler growth conditions and harmful gas emissions. The study results could provide a research basis and ideas of reference to establish a relationship between LED illumination information, broiler growth performance, and harmful gas emission.
