NPF uses indigenous micro-organisms to create a healthy environment

Natural Deep Bed Pig Farming uses indigenous micro-organisms (IMO's) to create and maintain a healthy deep bed litter flooring. It is these micro-organisms that will help break down fecal matter rapidly leaving you with a fertilizer rich material whilst ensure no smells or flies (an important factor in the tropics in particular where pigs and millions of flies can be synonymous). We apply a home made enzyme/microbe mixture fosters rapid anaerobic digestion of waste.

What are micro-organisms?

Micro-organisms are all around us. They are vital to humans and the environment, as they participate in the Earth's element cycles such as the carbon cycle and nitrogen cycle, as well as fulfilling other vital roles in virtually all ecosystems, such as recycling other organisms' dead remains and waste products through decomposition. They are a key component of natural pig farming deep bed system. 

Why are micro-organisms so important to natural pig farming?

Micro-organisms do most of the material circulation in nature. They decompose and convert complex organic materials such a dead plants and animals, secretion, excretion and organic fertilizers into simple compounds so that material circulation is possible.

They also create complex or organic compounds by synthesis. They produce various materials such as anti-biotic substances, enzymes and lactic acids which suppress various diseases and promote chemical reaction in the soil. Without the enzymes the chemical reactions cannot take place so rapidly.

The natural pig farming deep bed system harnesses these beneficial properties to successfully raise animals and grow crops in the most low cost environmentally friendly way. They are a key element of all inputs into the Natural deep bed pig farming system, promoting health and preventing disease. They are also a key input to ensuring a healthy pig pen floor.

What natural solutions do we use to encourage a healthy pen bed?


The natural pig farming deep bed system focuses on the use of indigenous micro-organisms (I.M.O). These are the natural organisms that can be found in the local area. Natural pig farming wishes to foster I.M.O’s because they are best adapted to the local environment making them stronger and more effective than micro-organisms found elsewhere or commercially artificially created micro-organisms. 

Natural pig farming harnesses these beneficial properties to successfully raise animals and grow crops in the most low cost environmentally friendly way. They are a key element of all inputs into the natural pig farming deep bed system, promoting health and preventing disease. They are also a key input to ensuring a healthy pig pen floor.

We tend to use two different enzyme/microbe rich mixtures (either of which can be used) that have foster high indigenous micro organism activity when used in the deep bed flooring. They are cheap, easy to make solutions and are produced by fermenting natural plant and fruit materials with sugar. These are diluted in water and poured via watering can onto the pen bedding once a week.

1) Fermented Plant Juice (FPJ)

This is one of the two very effective solutions we make to encourage high IMO activity in the deep pen flooring. Below is the process you need to follow to create your FPJ solution.

  • Pick plant material you wish to use early in morning before plant loses nutrient values to photosynthesis.
  • Any green plant / vegetation will be fine to use: We tend to use Chinese water vegetable which grows wild and is readily available but plants like banana sprout, young bamboo etc. can also be used.
  • Chop plant up into very small pieces
  • Add half plant material to a container and line with half the sugar
  • Add remaining half and add remaining sugar
  • Compress with weight on top (a bag filled with water is very effective)
  • Quantity: 7kg plant material to 3 kg sugar
  • Leave for 8-10 days
  • Drain and collect the juice – this is now your fermented plant juice solution (FPJ)
  • When ready to apply to bedding add approximately 2 spoons of FPJ to 10 liter of water
  • Pour via watering can onto the pig pen bedding (and then continue to add to the flooring on weekly basis)

Just this small addition of FPJ will stimulate high indigenous micro-organism development and activity sufficient to rapidly break down any excrement and keep the bed healthy and smell free.

2) Fermented Fruit Juice (FFJ)

This is the other solution you can use to foster high IMO activity. You can use any kind of fruit but those fruit types that are likely to generate lots of juice are best.

  • Pick the fruit
  • Chop into small pieces
  • Add 1kg fruit : 1kg sugar
  • Put half the fruit in a container and add half the sugar.
  • Add the remaining fruit and add the remaining sugar.
  • Seal container with paper lid (this allows for air to enter and leave container).
  • Leave for 8-10 days.
  • Squeeze fruit to extract all juice.
  • Pour juice into jar.
  • Use 2 spoons of juice to 10 liter of water. Mix.
  • With watering can pour water on the bedding surface of the pig’s pen.

Routine weekly use




Whilst you can use either the fermented plant juice or fermented fruit juice to stimulate rapid anaerobic digestion of waste, we tend to use a mix of both in the same water. Adding the solution to the bedding once a week ensures a high level of micro-organism activity which will keep your bedding healthy and free from smell.



Natural pig farming v factory farming

IMO solution to promote deep bed health

Natural pig farming

Factory farming

Uses power or nature to treat excrement



Produces manageable quantity of waste



Does not multiply waste through use of water to flush and channel waste away from pens



Converts waste to earth friendly matter rather than wet slurry



Does not need large slurry holding lagoons



Produces organic rich fertilizer that build lasting nutrition and health back in to the soil



Does not pose a threat to the environment

– no smell, no flies, no run-off
