The explosive growth of swine production at high stocking densities in confinement
farming worldwide, has raised concerns the environmental impact, health and livestock
productivity and the production of associated gases in this type of large-scale farms. The aim of
this paper was to study the methane gas concentration and emissions of ten different typologies
of swine production installations. The facilities were in the department of Antioquia - Colombia,
they were located between 800–2,300 meters above sea level (m.a.s.l.) of heights, they mainly
employed natural ventilation as refrigeration strategy and they were used for pigs in fattening
stage. Methane measurements were taken at animal height. Sensors were located at intermediate
points of the ventilation inlet and outlet areas. The behaviour of methane concentration and
emission of the facilities were analysed along with the correlation and temporal evolution of
climatic variables, comfort indices and construction typologies. The information was analysed
using descriptive statistics, analysis of variance (ANOVA) and principal component analysis
(PCA). Were found an average of CH4 Emission Rate (ER) per facility (kg year-1
) of 607.9,
Global Warming Potential (GWP) per facility (kg year-1
) of 15,197.42 and significant correlations
between ER and cleaning frequency (CF), animal unit (AU), air flow (Q), animal density(AD)
and relative humidity (RH) were evidenced. This is the first research reported in Colombia, that
will be important to create some governmental policies.
