“…Details of the study design, study buildings, and methodology used for analysis have been published (Banhazi et al, 2008b;Banhazi et al, 2008c) as part of this series, and therefore only the specific methods used for temperature, humidity, and ventilation measurements are given here. In brief, 160 piggery buildings from 40 farms were included in the study, and the buildings were selected to represent a range of typical construction methods used in Australia (Banhazi et al, 2008b).…”

Between autumn 1997 and autumn 1999, we measured ventilation rates (using a CO 2 balance method), air temperatures, and relative humidity (using self-contained dataloggers with built-in sensors) in 160 pig housing facilities in Queensland, South Australia, Victoria, and Western Australia, in each case over a 60 h period. In some buildings, the internal air velocities above the animals were also recorded. While the monitoring instruments were being set up, a detailed questionnaire was used to collect data on major housing features and management factors. This information was statistically analyzed to quantify the effects of housing and management factors on the resulting environment conditions using a multifactorial analysis. The overall mean air temperature, relative humidity, internal air velocity, and ventilation rate were 20.3°C, 58.9%, 0.12 m s -1 , and 663.9Ăm 3 h -1 500 kg -1 live weight, respectively, across all buildings. Internal building temperature and humidity were affected statistically by the type of insulation material used, the classification of buildings, and external climatic conditions. Ventilation rates were primarily affected by the type of ventilation system used, height (size) of ventilation openings, stocking density (kg m -3 ), and length, width, and height of buildings. These findings should aid the development of strategies for the industry to improve environmental control in piggery buildings.

“…Ammonia accelerates the formation of fine particulate in the atmosphere and plays a crucial role in the acidification and eutrophication of ecosystems (Krupa, 2003). In livestock buildings, NH3 causes adverse effects on production, health and welfare (Banhazi et al, 2008). Ammonia emissions have significantly increased in many developed countries, as well as in some developing countries over the last 50 years (Aneja et al, 2008).…”

A total of 48 crossbred (Landrace Yorkshire Duroc) pigs (2 months old; 28.38±2.62 kg body weight) were randomly assigned to either a control (basal diet) or 0.5% artificial zeolite (AZ) [basal diet + 0.5% AZ, dry matter (DM) basis] dietary treatment group in a completely randomized block design. Growth performance, immunity, muscle composition, carcass quality, faecal microflora concentration and noxious gas emissions were then investigated. No significant variation was observed in average daily gain (ADG), average daily feed intake (ADFI) or gain:feed [kg gain/kg dry matter intake (DMI)] ratio between treatments. The IgM and IgA levels remained unchanged, whereas the IgG level increased in the AZ dietary group relative to the control (P<0.05). Carcass quality, muscle composition and cholesterol level were also unaffected by AZ supplementation (P>0.05). Although AZ had no significant effect on fecal yeast and Lactobacillus spp. concentrations, a significant reduction was observed for Bacillus spp. in growing and E. coli both in growing and finishing pigs (P<0.05). Additionally, AZ supplementation led to a reduction in faecal ammonia (NH3), sulphur dioxide (SO2) and hydrogen sulphide (H2S) gases relative to the control (P<0.05). Based on these results, AZ had positive effects on faecal E. coli concentration and noxious gas emissions; however, further study with different levels of AZ to better understand its effects on growth performance of grower to finisher pigs is warranted.

“…These pollutants negatively affect the health and welfare of both animals and humans and can potentially reduce the production efficiency of livestock and compromise the health of farm workers. Airborne emissions from piggery buildings also contribute to global warming, odor, and environmental pollution (Banhazi et al, 2008b). Occupational Health and Safety (OH&S) issues are increasingly important to both employers and employees within the pig industry.…”

“…Occupational Health and Safety (OH&S) issues are increasingly important to both employers and employees within the pig industry. The ability of large operations to maintain the health of staff is related to working conditions and acceptable air quality (AQ) in livestock buildings (Banhazi et al, 2008b). Therefore, it was realized that the development of an accurate, low-cost, and user-friendly kit for monitoring airborne pollutants was essential if appropriate AQ improvement strategies were to be implemented on farms.…”

“…Subsequently, a study was designed to select, develop, and consolidate low-cost techniques for measurement of airborne pollutants. Essentially, our aim was to develop an extension package (or education tools for farmers) that can be used to promote the results of a major AQ study undertaken in Australia (Banhazi et al, 2008a;2008b;2008c;2008d). In addition, it was essential to establish an organizational structure and data management system that would enable these measurements to be performed on a routine basis with minimal labor use.…”
