Description
Summary:Poultry litter is often highlighted to be a major source of odours associated with emissions from poultry production sheds and the post-treatment of used poultry shed litter. The addition of adsorbent to bedding material is often reported as a litter odour management strategy. Three commercial materials (activated carbon, silica gel and zeolite) that are often used as odour control products were tested in odorous litter under controlled environmental conditions. The effectiveness of the adsorbents was determined by chemical and olfactory analysis. In general, the addition of adsorbents did decrease the volatility of volatile organic compounds (VOCs) from the bedding material at dissimilar rates across the abatement trials. However, reduction in hedonic tone was not noticeable, mainly due to the emission of ammonia from the trial bedding material. The results showed that no single odour control product is capable of reducing or removing all the volatiles present in the odour emissions from poultry shed litter.
