What are the effective methods for deodorizing farms?
As the scale of livestock production expands and intensification increases, producing large numbers of poultry and livestock also releases a large amount of foul-smelling matter. These odors not only harm the health of the poultry and livestock, lowering their resistance and hindering production performance, but also affect the health of the keepers and pollute the environment around the pig farm. So how should farms remove this foul odor? Let's take a look.
1. Deodorizing through clever feeding
The foul odor of farms mainly comes from a variety of smells with relatively complex components, mainly caused by the excrement of poultry and livestock, so deodorizing through clever feeding is adopted. In pig farming, adding enzyme inhibitors to the pig's diet can reduce the ammonia content by 50% and the hydrogen sulfide content by 18%. Adjusting the crude protein content in pig feed to 10% and adding appropriate amounts of lysine, tryptophan, etc., can reduce the nitrogen and ammonia emissions of pigs and reduce the foul odor. In chicken farming, adding 1%-2% charcoal residue to the chicken's diet can make the manure dry and reduce the odor. Adding 2%-5% zeolite powder can also reduce the moisture content and odor of the manure, and also helps improve feed utilization.
2. Physical deodorizing
Charcoal, activated carbon, coal cinder, quicklime and other substances have excellent adsorption effects. These substances can be put into a mesh bag and hung inside the pen, or scattered on the ground. This can both adsorb the foul odor in the air, achieving an excellent deodorizing effect, and also play a role in disinfection and sterilization.
3. Chinese herbal medicine deodorizing
Mugwort leaves, Atractylodes lancea, Isatis indigotica leaves or garlic stalks can be burned inside the pen in a certain proportion. This can both achieve a deodorizing effect and play a sterilizing role, especially with better results when used in empty houses. Chinese herbal medicines for clearing heat and detoxifying can also be fed to reduce bacteria in the digestive tract, and can also lower the ammonia content in the air and reduce the odor.
4. Chemical deodorizing
The excrement of poultry and livestock should be cleaned up promptly every day and piled together, with ferrous sulfate sprinkled into it, which can inhibit manure fermentation and decomposition and reduce the odor. Other substances such as hydrogen peroxide, potassium permanganate, copper sulfate and acetic acid also have excellent odor-suppressing effects. Alternatively, low-concentration benzoic acid or acetic acid can be sprayed on the bedding, or copper sulfate and an appropriate amount of slaked lime can be sprayed on the ground, which can also reduce the odor of the chicken house.
