Studies have already been completed in the Midwest of the USA to assess the THP, SHP, and LHP of modern pig and poultry buildings. Similar calorimetric studies will be needed to extend the knowledge to other livestock species (e.g., beef and dairy cattle), types of housing systems, and ...
To develop adequate regulations, a large-scale, government-financed monitoring programme was started in the mid-1990s to establish odour emission levels for both conventional and low ammonia emission housing systems for cattle, pigs and poultry. The results indicate that high- and low-odour emission...

Bacteria in the air of animal housing is assumed to have an impact on the health of the humans and the animals in them and on the environment. The bacterial count in poultry housing systems is particularly high in comparison to those of pigs and cattle. Little is known about the bacteria ...
Cattle and buffaloes AFOs cater for 3.3% of world heads but produce 12.2% of cattle and buffaloes meat (HLPE, 2016). By 2017, there were approximately 450,000 AFOs, of which 20,000 CAFOs, in USA. In 2010 in Argentina, there were 2278 feedlots with a total of 1.6 million cattle, ...
of the sector [40,79]. While pig production systems are associated with significantly lower negative environmental impacts than other meat production systems (e.g., beef cattle) (Fig.1), pork is the most popular meat product globally [14,41] and therefore not a negligible contributor to ...

Precision Livestock Farming (PLF) plays a key role in the advancement of animal housing, since it is associated with the improvement of animals’ health and welfare status, ensuring sustainability and efficiency of farms. The main objective of researchers is the development of systems for real-time...
The systems are subdivided into, communal (subsistence) and small-scale (subsistence-cum-commercial). In the communal sector, ruminant production is often restricted to small, marginalised areas (Scholtz et al., 2011). Individual households keep small herds of cattle, sheep and goats comprising...
The objective was to compare odour emissions, hedonic tones and NH3 emissions from three cage layer housing systems: a deep liquid manure pit and a manure belt with natural or forced air drying. The former system consists of “A” frame layer cages located over a closed pit containing the ...
