Effect of Odour due to Poultry Waste in the Neighbour: The nearest neighbour was located at least
20 metres away from the poultry farm. The odour level of poultry waste in the neighbourhood was
assessed by interviewing neighbours at every direction nearest to the farm before and after the
establishment and operation of bio-digester with poultry waste. They all reported that the level of
odour is not perceived. On the other hand, farmhouse dwellers reported that they have been inhaling
offensive smell produced from putrefying poultry waste. The study also found that the odour level of
poultry waste is perceived more in wet condition than when it is in fresh and dry form. This is
attributed to the emission of ammonia gas, which has offensive odour. Furthermore, it is to be noted
that there is no protest as yet from the public against the poultry farm odour.
