'Climatization and environmental control in animal housing' is the rem
it of Working Group 13 of the Commission Internationale du Genie Rural
(CIGR, the International Commission of Agricultural Engineering). The
current members of the Working Group are drawn from eleven European c
ountries; the UK is represented by Jamie Robertson of the Centre for R
ural Building, Aberdeen. The Working Group has now published its third
Report, entitled 'Aerial environment in animal housing. Concentration
s in and emission from farm buildings'. This latest Report, which was
presented at the 12th CIGR World Congress in Milan in August this year
, condenses in one volume the current state of knowledge regarding air
borne contaminants (gases, dusts, pathogens, odours) associated with l
ivestock housing. Here, by kind permission of Dr Krister Sallvik, Chai
rman of CIGR Working Group 13, we reproduce a summary extracted from t
he Report.
