EM a coined to the words effective
micro organisms
EM is a NATURAL PRODUCT prepared with efficient
microorganisms that accelerate the natural decomposition
of organic matter. The microorganisms in EM are beneficial
and highly efficient. These microorganisms are not
harmful, not pathogenic, not genetically modified, not
chemically synthesized.
 They are well known natural microorganisms such as
yeasts and the lactic acid bacteria (Lactobacillus) that
promote the process of beneficial antioxidative
fermentation, accelerate the decomposition of organic
matter and promote the balance of the microbial flora.
• EM is:
• Non-poisonous.
• Non radio-active.
• Non-corrosive.
• Non volatile
• Non inflammable.
• Does not have a quarantine period.
• Biodegradable
• Safe for human, animal and plant
health and for the environment
What Em consist from
The microorganisms found in EM belong to 3 well-known groups:
lactic acid bacteria (used in the making of yogurt, cheeses, etc.),
yeasts (used to make breads, beers, wines, etc.) and phototrophic or
photosynthetic bacteria (present in green seaweed and in any soil
The idea of using effective micro-organisms (EM) in agriculture
was developed by Professor . Teruo Higa of the Ryukyus University
in Okinawa, Japan.
EM works in two main ways:
a)by competitive exclusion from other harmful
b) through the production of beneficial byproducts such as enzymes, organic acids,
amino acids, hormones and antioxidants
Applications of EM in livestock
 Beneficial micro-organisms, other than contributing to the
production of good wine and cheese, are also invaluable help
in livestock production activities.
 EM has a wide range of applications in livestock production
such as pasture recuperation, livestock health and installation
sanitation. The use of EM Technology is simple and very much
adaptable to actual conditions of livestock production
Use EM in Feed and Water:
 The use of activated EM in the feed and water given to
livestock has as objective to increase the digestibility and the
assimilation of nutrients as the micro-organisms such as
lactobacillus and saccharomyces found in EM have been used
successfully as probiotics in animal feed. In addition to
making the digestive process more efficient in ruminants, EM
also reduces the production of methane gas from the
intestines of the animals.
 EM can be used in two ways in animal feed:
1. by direct fermentation of a feed source (Bokashi).
2. by direct aspersion over the concentrate or ration of the
What is Bokashi?
The word “Bokashi” is of Japanese origin and means
fermented organic matter
THE Benefits
1- Eliminate the bad odor within the
installations of the livestock.
2- Reduce the incidence of flies,
ticks and other undesirable insect
3- Significantly better the health of
the animals (e.g. reduction of
mastitis and diarrhea ).
4- Reduce the requirements of
regular medication, antibiotics and
5- Reduce the stress factors of the
animals thereby strengthening the
immunological system against
6- Better the fertility period of the animal.
7- Animals expose to EM are noted to have
better skin and healthier hoofs.
8- When used with feed it improves the
digestibility of the animals and
consequently better the feed conversion
rate and hence an improve growth rate and
weight of the animals.
9- Reduce the production of methane gas
in the intestine of the animals and hence
improve the feeding habit of the animals.
10- Improve microbiologically the quality
of the water by its enrichment with
beneficial substances such as amino acids,
vitamins and enzymes that better the
digestibility and nutrient assimilation of the
Applications of Em in poultry
EM is transforming into a great tool for animal production due to
its various effects as probiotics, antigens and a natural
cleaner. In this same manner it can be applied in drinking
water for animals and in animal feed.
Use in Feed and Water
One of the simplest means of using the EM is by mixing EM in
the water that is given to the birds.
EM can be used in two ways in birds feed:
1. by direct fermentation of a feed source (Bokashi)
2. by direct aspersion over the concentrate or ration of the
Benefits:1- Eliminate undesirable odor from
2- Equilibrate the micro-flora
within the intestines of the birds
and consequently improve the
feed conversion and weight gain
due to increase in nutrient
3- Reduce the incidence of diarrhea
4- Increase the weight gain with the
same feed consumption .
5- Reduce the mortality rate.
6- Improve bird health and quality
of meat through the reduction of
cholesterol .
7- Produce heavier eggs ( +3.7%)
with a much darker-colored yolk
due to better carotene synthesis;
a more consistent egg white due
to improved synthesis of albumin
and a harder shell due to better
assimilation of calcium.
8- 6.5% increase in size of eggs.
The following informs of the benefits of EM Technology.
1-Pasture Recuperation
2-Pest Control
3-Management of Organic residues
4-Installation Cleaning and Odor Control
1-Pasture Recuperation
EM can be used to better the physio-chemical and microbiological conditions of soil; it also helps in accelerating
natural decomposition of organic residues in the field.
EM will have little effect in soils poor in organic matter (less than
1.5%) since Organic Matter is necessary for the organisms to
work more efficiently. It will be required to incorporate soil
organic matter within such soils.
1- Accelerate natural decomposition of residues left in the field
after harvest.
2- Increase the viability and availability of nutrients in the soil
3- Maximize the conversion of organic matter into humus
4- Increase the natural production of humus and favors the
production of beneficial organic substance that promotes
growth and improves nutrition of the plants due to soluble
phosphorus and potassium availability.
5- Increase the population of beneficial micro-organisms
that helps in suppressing micro-organisms that cause diseases
consequently reducing the use of pesticides.
2-Pest Control
EM can be used to maintain the health of the herd. To do so
it’s necessary to realize a different activation process that
consists of the addition of natural products such as molasses,
fruit vinegar.
Reduce ticks and fly infestation on animals.
Reduce stress on animals.
Reduce the use of agrochemicals on the animals.
Reduction in overall cost of the farm.
It’s a natural product that is 100% safe to human,
animal and environmental health
3-Management of Organic Residues
EM can be used in the management and treatment of animal
manure within the corral thereby transforming the residues in
compost of excellent quality, enriched with microorganisms
and beneficial substances.
1- Increase the fermentation process of organic residues between
2 to 3 weeks.
2- Increase the availability of nutrients present in the organic
residues (principally, nitrogen and phosphorus).
3- Accelerate the conversion of organic matter into humus.
4- Enrich organic material with beneficial micro-organisms.
5- Reduce cost of transportation of residues destined for the field
due to decrease in its volume after composting.
6- This decomposition process is odorless hence eliminating the
presence of insects (e.g. house flies).
7- Eliminate bad odor and flies from the installations.
8- This method is a cheap source of manure and other organic
residue management.
4-Installation Cleaning and Odor Control
EM can be diluted in water storage tanks to clean the
installations or simply spray manually for improve hygiene and
control of odor.
Benefits :1- Significantly reduce undesirable odor within the
2- Reduce the presence of flies and other insects.
3- Help to obtain quality organic residues that can be used as
4- Use of activated EM reduces the overall cost of operations.
5- Reduction in the use of agro-chemicals and antibiotics.
The EM technology when it developed was
intend to contribute effectively to the
agriculture and it has already applied ,but in
animal production this efficiency is not
effectively reached , so it’s a fertile material
for more research.
