[EN] Livestock housing is one of the main sources of ammonia (NH3) emissions from agriculture.
Different management and environmental factors are known to affect NH3 emissions from
housing systems. The aim of this study ...
[EN] Ammonia, methane, nitrous oxide and carbon dioxide emissions were measured during a
complete production cycle in an enriched cage laying hen facility under Oceanic climate
conditions. Continuous monitoring of gas ...

[EN] Ammonia, methane, nitrous oxide and carbon dioxide were measured during a complete productive
cycle in a laying hen facility under typical Atlantic conditions. Continuous monitoring of gas
concentration, ventilation ...
[EN] Standardized measurement protocols are required to reduce ammonia (NH3) emissions. In vitro measurement of NH3 emissions consists in trapping the emission from an emitting source in an acidic solution under controlled ...

The design of structures for animal husbandry has energy and environmental implications. Particularly,
the design of broiler houses should consider the comfort of animals in different situations, which is
crucial for ...
[EN] Gas emissions from broiler production have been the subject of intensive research. However, little experimental information exists for farms under the particular management and environmental conditions of the European ...
[EN] There is a need to characterize gas concentrations and emissions from rabbit production. A study was conducted in order to determine ammonia, nitrous oxide and carbon dioxide concentrations and emissions in three ...
[EN] The objective of this work is to characterize two contrasting systems of fattening pigs in Uruguay. A total of 96 pigs (average 41.7 kg) were divided into eight groups of 12 animals, representing two production systems: ...
[EN] Pig slurry is a valuable fertilizer for crop
production but at the same time its management may
