Most of the questions associated with controlling odours in poultry or pig farms are:
- Where are the odours coming from?
- What is the level of difficulty in managing the odours?
- How much will it cost me to control these odours?
Weel, this article will discuss the seven (7) practical steps that can be adopted to reduce odour in a piggery or pig farm.
1. Good farm location: The location of your livestock farm matters a lot. The production facilities also depend on the farm location. This is why you must take into account the distance of the piggery from residential places, the scale of production, and waste disposal channels available. A hog farmer must also study the past prevailing winds for their direction, and regularity in different times of the year before siting a farm. The farm terrain also influences the intensity of the odour because as winds subside, it flows downward via valleys. Therefore, choosing an appropriate site for raising your chickens or pigs is the cheapest means of controlling odours in the farm.
2. Proper handling of manure: When you inject manure (dung of chickens or pigs), you’ll reduce odour to about 52-76% in comparison to spreading the same manure. The injection of manure here is just like evacuating sewage from a sewage tank through the help of suction machines.
3. Manipulating the pigs’ diet: This may include reducing the levels of crude protein and bounding crystalline amino acids in the diet of the pigs. This is another cheap method and it can reduce odour by 20%.
4. Ventilation of the pit: The majority of the odours generated in a poultry or pig farm comes from the dung pit. This adds more than half to the whole odour. When the dung pit is ventilated, volatilization is increased, and that provides limited advantages to the air quality inside.
5. Use of Biofilters: You can reduce odours and ammonia up to 65-80% by drawing exhaust air through a biofilter bed. A biofilter is an odour-curbing technology that is very effective, but its moisture content must be managed appropriately. You must ensure that the biofilter design is very compatible with your farm ventilation system.
6. Plant trees and shrubs: This is the point where planting trees, shrubs and other vegetative plants are very important. So if you want to reduce odour in a pig or poultry farm, then plant trees and shrubs around the farm. This won’t cost you much; just plant them.
7. Good General Management: If you manage your farm in terms of waste management, sewage disposal, and proper cleaning of the chicken or pig’s pens, then you will be faced with a little or no odour-related problem.
