“…The animal CO 2 production under normal farm conditions has normally a diurnal variation of ±20% (Pedersen et al, 2008). Carbon dioxide (CO 2 ) concentrations and emissions were assessed over six fattening periods in the study of Knížatová et al (2010d). The major part of CO 2 seemed to have its origin from bird respiration with assumed production of approx.…”

Brouček J., Čermák B.: Emission of harmful gases from poultry farms and possibilities of their reduction. Ekológia (Bratislava), Vol. 34, No. 1, p. 89-100, 2015. This review is devoted to methodology that can help to assess emission of gases from poultry housings and could be used to expand the knowledge base of researchers, policymakers and farmers to maintain sustainable environment conditions for farming systems. Concentration and emission of ammonia, methane, nitrous oxide and carbon dioxide in poultry barns are discussed in this paper. Surveys of ammonia and greenhouse gases mean concentrations and emission factors in different poultry systems are showed. This paper is also gives the findings in emission mitigation, especially to different manure handling practices, management schemes, housing and facility designs for broilers and laying hens. Finally this paper focused on investigating practical means to reduce air emissions from animal production facilities.

“…Air concentrations of microorganisms and noxious gases depend, among others, on bird age, type of housing system and stocking density, manure management, efficiency of ventilation, and microclimate that is primarily determined by air temperature, relative humidity and airflow rate. The concentrations of these pollutants have been increasingly investigated in intensive poultry production (12)(13)(14)(15).…”

Good air quality in poultry houses is crucial for animal health and productivity. In these houses, air is generally contaminated with noxious gases and microorganisms, the concentrations of which depend on numerous factors including microclimate. In this case study, the relation between microclimate and air concentrations of noxious gases and microorganisms was investigated in extensively reared turkey house. The study was carried out at a family household in Dalmatia hinterland, Croatia, with 50.3±3.1 turkeys kept in the house during the study period. Air temperature, relative humidity, airflow rate, concentrations of ammonia, carbon dioxide, bacteria and fungi in indoor air were measured three times per month from September to December, in the morning, prior to releasing turkeys out for grazing. Air temperature ranged from 9.73 to 26.98 °C, relative humidity from 63.29% to 75.08%, and airflow rate from 0.11 to 0.17 m/s. Lowest ammonia and carbon dioxide concentrations were measured in September (2.17 ppm and 550 ppm, respectively) and highest in December (4.50 ppm and 900 ppm, respectively). Bacterial and fungal counts were lowest in December (2.51x10 5 CFU/m 3 and 3.27x10 3 CFU/m 3 air, respectively) and highest in September (6.85x10 5 CFU/m 3 and 1.06x10 5 CFU/m 3 air, respectively). Air temperature and relative humidity showed negative correlation with concentrations of noxious gases and positive correlation with air microorganisms (P<0.05 all).

“…As visible in Figure 7.3c, 𝐶 ̅ i_NH 3 exceeded the threshold mainly in the central part of the monitored period. Although this tendency is described in literature [322], the evolution of NH 3 concentration is, to some extent, hard to predict, being influenced by litter management, environmental conditions, ventilation rates and broiler health status [329]. In Figure 7.3c, it stands out that during the first days, 𝐶 ̅ i_NH 3 was considerably below the 𝐶 ̅ lim_NH 3 .…”

“…It has been reported that most commercial farms across Europe rear broilers at densities higher than 33 kg m −2 [321]. However, gas concentrations exceeding the limits established by the 2007/43/EC Directive have also been reported in commercial poultry houses for both NH 3 [88] and CO 2 [322].…”

“…Despite it is known that NH 3 emissions are affected by airflow rates and patterns [336], the effect of changing ventilation rate on gas emissions is unclear in research. On the one hand, Knížatová et al [322] suggested that higher ventilation is the reason of increased emissions in summer. However, higher ventilation rates at certain θ air_i and 𝑅𝐻 i also contribute to litter drying, thus reducing the emission of NH 3 [329].…”

Improving Climate Control and Energy Performance in Greenhouses and Livestock Houses: Modelling Advances and Experimental Results

Improving Climate Control and Energy Performance in Greenhouses and Livestock Houses: Modeling Advances and Experimental Results" Socio-demographic trends, such as population growth and urbanization, are leading to a significant increase of the world food demand. At the same time, there is a shift of the human diet toward livestock products, vegetables, and fruit rather than cereals. In this context, greenhouses and livestock houses can play a primary role since they can supply the necessary agricultural products with higher yields than on-field crop production and extensive animal farming. One way in which productivity is enhanced in these agricultural buildings is by a fine-tuned control of the indoor climate conditions. For this purpose, mechanical climate control systems are often adopted, but they entail a considerable energy consumption whose estimated increase may jeopardize the transition toward a sustainable agriculture. The overall objective of this thesis, hence, is to contribute to the transition toward a sustainable agriculture by improving the energy performance for climate control of greenhouses and livestock houses.To achieve this objective, a three-pronged approach was taken involving a literature review, experimental monitoring campaigns, and energy modelling activities. The literature review was performed to unpick the tangle of mutual relations between climate control and other domains of agricultural production. The nexus between energy performance and climate control was investigated analyzing real datasets acquired through monitoring campaigns performed in a greenhouse and two pig houses. This nexus was further studied adopting a numerical approach which led to the development and validation of three energy simulation models for greenhouses, broiler houses and pig houses. Each simulation model integrates the main features typical of greenhouses and livestock houses to accurately estimate the time profiles of lumped indoor climate conditions and thermal and electrical energy consumption. The opportunities in improving the energy performance and the indoor climate conditions provided by the developed energy models were explored by analyzing specific energy-related problems. The broiler house energy model, in fact, was adopted to evaluate the potentialities of a new primary energy approach for the energy-efficient envelope design of broiler houses. The same model was applied to evaluate the variation of energy consumption achieved by an improved ventilation strategy aimed at enhancing broiler welfare by reducing indoor noxious gas concentrations.This thesis contributes to the transition toward a more sustainable agriculture providing new knowledge and tools necessary for improving the energy performance for climate control of greenhouses and livestock houses. The performed analyses, in fact, quantify potential decrease of energy consumption achievable through the implementation of energy-efficient measures at both Crop production in greenhousesGreenhouses are among the most widespread and effi...
