6. Olfaction and malodours in pig farming areas

Odours play a crucial role in livestock production. This chapter describes the fundamentals of olfaction and details various studies. The concepts of malodour index gas and iso-osmic (equal odour) and isodysosmic (equal malodour) lines are introduced along with malodour management principles in an intensive PFA. The question and answer section presents opinions that should be helpful when making judgements on the matter of dysosmia (malodour) management in a PFA.
