One of the primary challenges for poultry, livestock and hog farm owners is to control the smell on farms and in the neighbourhood. Odour complaints are not unheard of and range from the odour being a nuisance, to a health risk, to causing water contamination, to lowering values of homes in the neighbourhood.
Some of the sources of odour from a farm are:
- High numbers of animals in a small area
- Storage and spreading of bio-solids and sewage sludge
- Litter moisture content
- Manure that is collected
- Waste accumulated before disposal
Several odorous gases are generated in poultry farming. However, ammonia (NH3) is the biggest miscreant. Strong smelling and colourless, ammonia can be corrosive as well as irritate the skin and eyes. Being lighter than air, it circulates more easily.
While it may not always be possible to completely minimise the smell from spreading, here are a few ways to help effectively monitor odours generated on farms:
Feed and Diet
When a spillage occurs, clean it up quickly. Cut protein levels in food and use additives, instead. Avoid grinding the food too fine.
Put sufficient straw or litter where the animals are bedded. This will help prevent ammonia escaping. Remove and manage animal litter when the climate is good.
Work to control humidity and temperature, empty the manure belts once or twice a week, and cover the place or pit where the manure is stored to prevent gases from escaping.
Spreading of Manure
When carrying out land spreading of manure, take into account factors such as wind direction. Keep tabs on the weather and do not spread when it’s very warm as odours are stronger. Plan to carry out spreading of manure on weekdays rather than weekends, and avoid public holidays.
Ensure that the farm is well-ventilated. Sheds must have roof vents. Ventilation discharge points must be cleaned often.
These must be removed frequently, covered and kept away from sensitive receptors.
Monitoring and Planning
Stay updated on prevailing weather conditions and especially the wind direction. Conduct frequent checks for odours, diseases and pay attention to complaints.
Have a good system in place for the collection of dirty water and see to the maintenance of drains. When cleaning the building, ensure that dirty water is cleaned out.
