Livestock Solutions

In this section we are providing you with several of the most common application solutions with EM-1® Microbial Inoculant and EM-1® Waste Treatment for livestock operations including odors and problems associated with foul odors, manure management, and lagoon management.

A great benefit with EM-1® is that it is not specific to a type of animal. If you are raising hogs, the benefits you are looking for will be slightly different than someone that is growing chickens, however, the effect on ammonia is the same and the application rate is about the same as well. This means, if you are raising mink, sheep or goats, horses, or any number of animal, you can follow the guidelines we give you here in this section.

Please visit EMRO Japan's website, to find studies from over 100 countries using Dr. Higa's Original EM-1® products on virtually any animal that is commercially raised.

Activated EM-1® (AEM-1®) is loaded with antioxidants which help prevent rust and other corrosion on equipment, eliminate odors, and clean water. Using it regularly in animal exhibits will keep the equipment clean and odor and rust-free. Zoos can benefit from various application points with AEM-1®. Here are a few quick tips:

Animal Exhibits Odor Control

  • Cages: 2 ounces AEM-1® per gallon of water. Spray minimum of 3 times per week.
  • Water Clarity in Tanks/Aquariums: 1 part of AEM-1® per 10,000 parts water as a monthly maintenance. 
  • Manure: Gather manure and bring to area to compost (see landscaping section).

Eating Establishments

  • Food wastes: Ferment using EM-1® Bokashi and pickling in airtight containers for 2 weeks. The materials can then be added to worm bins, fed to animals, added to compost piles, or buried in the ground.
  • Kitchens: Mix a 50/50 solution of AEM-1® and non-antibacterial soap. This solution can be mixed in water for washing counters, floors, walls, windows, refrigeration units, stoves, and carpets. Dump solution down drain to add more microbes to the system.
  • Grease traps: Pour product down a common drain at a rate of 1 quart AEM-1® per 1,000 gallons holding capacity per week.
  • Septic systems: Pour product down a common drain at a rate of 1 quart AEM-1® per 1,000 gallons holding capacity per week.
  • Drains: Treat by pouring ¼ cup AEM-1® per main drain 2-3 times per week to eliminate back odors and keep drains flowing without backups.

Landscaping & Operations

  • Plantings: Inject AEM-1® into irrigation system at a rate of 5 gallons per acre. This can be done 4-8 times a year depending on climate.
  • Manures and Compost: As loading manure into compost pile, spray with a 4-ounce/gallon mixture of AEM-1® and water. Mound and cover with a tarp. Turn pile once per week for 4-6 weeks. There should be no ammonia or sulfur smells. As weeds sprout, turn them in.
  • Pile should be ready to use as mulch in 6 weeks. Or, the materials can be buried (be sure to cover with 8 or more inches of soil to keep weeds from sprouting) in trenches after 4 weeks.
  • Water Features: 32oz AEM-1® per 10,000 gallons of water per week to keep water clear and odor-free.

Veterinary Clinic

  • Clinic: Spray down floors and cages, wash counters and tables, windows, etc., with a solution of 1-3 ounces AEM-1® per gallon of water. Mop floors with ½ cup AEM-1® in mop water.
  • Litter: Use a 50/50 mix of EM-1® Bokashi and litter or 100% EM-1® Bokashi for litter. If 100%, the litter can be used as a mulch and fertilizer for ornamental plantings by landscaping department.

Building Maintenance

  • Restrooms: AEM-1® can be used to keep all bathrooms clean and odor-free. Mix ½ cup in mop bucket water for washing floors, stalls, tiled surfaces, windows and mirrors.
  • General Purpose Cleaning: Mix a 50/50 solution of AEM-1®and non-antibacterial soap. This solution can be mixed in water for washing counters, floors, walls, windows, and carpets.
  • Indoor Plants: Use ¼ oz of AEM-1® per gallon of water to wash plants. Use 1 teaspoon AEM-1® per gallon of water to water plants.

Effective Microorganisms® has a long history of use in livestock operations. It can be used for odor control, for lagoon and solid waste management (bokashi or compost), and for crops. Virtually every type of animal raised in a commercial farm has been treated with EM at one time or another. There are studies on cattle, hogs, chickens, ducks, turkeys, all sorts of aquatic animals, even turtles, elephants and hippos (see the information on zoos)!

For large commercial operations we sell ready-to-use products that are only available through salespeople or by calling us directly (866-369-3678). These formulations are available for specific operations by animal type: hogs, horses, poultry, dairy, etc. Suggested programs are broken down in the categories above.

Sizes available for these operations are 55-gallon barrel, 275-gallon tote, or via tanker delivery. Please call for rate quotes.

Some lagoons are in pretty good condition and just need a maintenance dose of Wt1000™. These would have a liquid surface and often reflect a purple color on the surface. These lagoons smell like very rich soil and do not emit foul odors. Other lagoons may need a more aggressive treatment plan (see bottom chart). These application rates can be used for manure pits, which are often found in hog barns, as well.

Aggressive plan for a lagoon: If the lagoon has a crust and/or a large volume of sludge, continue application until some level of clarity is seen. It would be wise to measure sludge levels to set a point of comfort level as to when to decrease application rates to a maintenance dose.
