Relating flock activity levels to odour variations in tunnel ventilated broiler sheds - preliminary results

摘要: Malodorous emissions are an inevitable part of intensive livestock production. Emissions fluctuate and their impacts subject to the surrounding topography vagaries weather. When handling odour complaints, regulatory authorities often faced with dilemma assessing situations after fact without any supporting data. Recent developments in electronic nose technology have enabled continuous in-shed measurement broiler sheds which can help identify periods elevated concentration (odour spikes). The issue then is determine what causes these spikes. Increased flock activity one possible cause. This paper examines concept using machine vision-derived indices characterise spikes delineate between normal emission levels directly attributable increased activity. implication findings that control should include monitoring taking action minimise or prevent hyperactivity flock, especially at those critical times day when most likely impact on neighbours result complaints.
