“…When the wind speed surrounding the coop increases, the distribution of scents in a horizontal direction decreases. Wind directions (north, east, south, and west) had average dispersion distances of 369.0, 197.8, 470.5, and 235.1 m, respectively [51].…”

This study aimed to calculate a sustainability index of duck farming. Data was collected through a questionnaire by a scientific judgment of expert researchers in duck farming. Data were grouped using the multidimensional scaling (MDS and MICMAC and analyzed using) comprising social, economic, ecological, technological, and human resources dimensions with a total of 38 attributes in Rapfish software. The sustainability index was calculated as 44.13%, which indicates that farming has a less sustainable category with consideration of some leverage factors. These findings indicate that the high feed price, fluctuations in the price of duck products, diseases, and an extensive maintenance system warrant further attention to improve sustainability. MICMAC's analysis showed that the intensity of counseling, knowledge of livestock health, and livestock waste management are the main driving variables and prerequisites in determining the sustainability of a duck business. The prospective analysis identified several strategies to improve sustainability that can be carried out, including increasing the capacity of human resources through training/counseling/comparative studies, increasing the capacity of existing institutions, and advocating and socializing intensive duck business cultivation.

“…Kyeong et al [80] evaluated the identification of key factors of dust reduction and the effect of dust reduction in nursery pig houses based on CFD technology. Yeo et al [77,81] used CFD to evaluate the key factors of odor dispersion (wind speed, wind direction, atmospheric stability, terrain condition, ventilation type, and so on). Kim et al [82] simulated the temperature and ammonia concentration distribution inside a nursery pig house by CFD, which was able to systematically quantify and analyze the distribution and change in environmental factors.…”

Environmental Factor Detection and Analysis Technologies in Livestock and Poultry Houses: A Review

et al. 2023

The environment in livestock and poultry houses plays an important role in the growth and reproduction of livestock and poultry. In order to obtain the environmental conditions of livestock and poultry houses in a timely and reliable manner, and eliminate adverse environmental factors, scholars have been exploring various methods to obtain and predict environmental factors. This paper reviewed the literature from the last 10 years, specifically focusing on technologies for detecting environmental factors in livestock and poultry houses, which can be mainly divided into three categories: research on the environmental monitoring and control of livestock and poultry houses based on detection equipment and wireless sensor technology; research on the distribution and regularity of environmental factors in livestock and poultry houses based on a mathematical model; research on the environmental simulation and detection of livestock and poultry houses based on computer technology. The current testing methods have their advantages and disadvantages. When studying environmental factors, researchers should choose the most appropriate method for data acquisition according to the actual situation. The proposed recommendations for achieving this goal are as follows: (1) The control of environmental factors should be combined with the physiological response of livestock and poultry. The needs of animals should be considered; (2) Novel approaches need to be developed to integrate energy requirements into the environmental regulation of livestock and poultry houses; (3) It is necessary to research and develop control models and strategies that can predict the environment in the houses, and the transient simulation method should be further explored; (4) Improve environmental detection and control accuracy through the coupling of different technologies.

“…An indication of the dispersion of atmospheric pollutants is the smell of polluting emissions. Using a CFD model developed by themselves, Yeo et al (2020) demonstrated that the odor dispersal distance of odor unit (OU) m −3 ranged from 129.7 to 1488.1 m depending on factor changes, being wind speed the most influential. However, this work does not indicate the height that this dispersion reaches.…”

The dispersion of atmospheric NH3 constitutes the most common passive polluting system in cattle stables. Although the studies carried out through computational fluid dynamics (CFD) are focused on improving the environmental conditions in situ to increase the productivity of stables, they do not refer to determining the environmental impact of NH3 emissions into the atmosphere. This work evaluated the distribution of the NH3 flux inside a barn using CFD and its relationship with environmental conditions through probabilistic analysis by the K2 algorithm. The initial data on environmental conditions were wind speed and direction, maximum temperature, and humidity from the nearest weather station in a region characterized by hot weather conditions during summer. The vertical trajectory was used to analyze the impact of long-range transport on the spatial distribution, where 75% is between 0 and 5 m in height, and 25% is between 10 and 20 m outside the eaves. The work concluded that temperature is the main parameter of influence.
