What are the effective methods for controlling odors on farms?

Method one: Choose high-quality feed ingredients. This improves the animals' utilization of them and reduces the amount of manure excreted.

Method two: Improve feed processing techniques. Proper processing helps improve the utilization rate of nutrients in feed by livestock and poultry, reducing feed waste and environmental pollution.

Method three: Lower the dietary protein level and add synthetic amino acids. By lowering the protein level in the diet and adding amino acids to regulate the amino acid balance, the utilization rate of nitrogen can be improved and nitrogen excretion reduced.

Method four: Increasing the amount of non-starch polysaccharides in the diet helps reduce the production and emission of ammonia.

Method five: Application of effective feed additives. The use of effective feed additives such as probiotics, enzyme preparations, acidifiers and zeolite can promote the digestion and absorption of nutrients by livestock and poultry, effectively improve the utilization rate of nitrogen-containing and sulfur-containing nutrients, reduce the excessive production of ammonia and putrefactive substances, and reduce the amount of manure excreted and the generation of malodorous gases, thereby alleviating environmental pollution from odors.
