Deep Litter Method(5 Steps To Make Animal Bedding)

Post by Pangoogroup on March 9, 2017

Deep Litter Method

The deep litter method- It can make a microbial environment.

This environment is formed through mixing microbial strains、sawdust、rice husk and certain nutrients in proportion then make fermentation.

It can decompose the waste excreted by livestock and poultry, Meanwhile, this environment can generate heat and eliminate odor.deep litter methodIn such an environment, livestock and poultry grow happily and healthily.

The feces are excreted directly on deep litter. Through animals’ rooting and artificial overturn, feces and urine and the bedding are intensively mixed.

Through beneficial microorganism fermentation, the organic matter in feces and urine are be resolved, making a strong ecological environment, while creating heat to keep the animal warm naturally.

Using the deep litter, the farm is with no bad smell, zero emission, no pollution and with low lost.

5.Differences and features for breeding different animals

Take large animals such as pigs, cattle, sheep,horses. For example,  A deep litter with an area of 10 Square meters.

1.Prepare materials:

  • Bedding: sawdust, rice husk, peanut shell, corn straw, corn cob. Choose two of the above materials, because the deep litter will become harden if there is only one material. Usually, the deep litter with straw and sawdust. The total weight of the two materials is 1.5 tons, laying thickness is 80cm. The weight proportion of the two materials can be 1: 2, 1: 1 or 2: 1.  It is all right as long as the total dry weight reach 1.5 tons.The deep litter can be used for about three years. It is highly efficient with low cost.
  • Deep litter dedicated Microbial Agents Pangoo Biobed:1KG
  • Some Water.

2.Production methods and steps

  • To mix PANGOO BIOBED with some of fermenting deep litters such as wheat bran or corn flour etc with the ratio of 1:5-10.
    Then to spread the mixture evenly 10 cm thickness on the deep litter.
  • Attention: To prevent dust, spray some water on the surface.

3.Final -period maintenance and management:

  • When the sawdust in the piggery become less, the lacking part and microbial strains should be supplemented properly. For pigs can easily root on the ground, the feed feeding amount should be controlled at 80%of the normal amount. Breeding density should be controlled strictly as follows:
  • Breeding density should be controlled strictly as follows:
    0.75 ~ 1 ㎡f or one piglet 1 ~ 1.5 ㎡ / for a growing pig
  • When the waste accumulates too much, it can be spread on the bedding, then stir the bedding down into 20 cm.
  • After the animals are slaughtered, the sterilization bedding must be stirred again. At the same time, it is necessary to regulate water and increase bacteria.Then Insecticide disease-free pigs are put into it for new breeding
  • Death precautions: The moisture of deep litter must be not higher than 50%. When the moisture is too high, dry bedding can be added then turn it. However, the moisture can not below 35%. While the moisture is too low, water should be supplemented in time in case of respiratory disease caused by dry bedding up dust Keep indoor good ventilation
  • Keep indoor good ventilation Permeability management: the bedding should be often turned, the depth of turn is about 25 cm.
  • Permeability management: the bedding should be often turned, the depth of turn is about 25 cm.Usually, Water and faces are needed in case of uniform overturnedDisinfection :Normal disinfection can be carried out with deep
  • Disinfection :Normal disinfection can be carried out with deep litter. Breeding pigs with deep litter, pigs themselves rarely get sick, even less chance to catch a cold. But when they suffered a local, regional, or national epidemic diseases, the whole pig farms must be disinfected thoroughly, at the same time, normal disinfection still can be processed. It has a little influence on deep litter.Disinfectant has a little influence on the microorganism just in the upper surface .it is not a big threat to hundreds of billions of microorganism in deep litter.
  • Epidemic prevention: During the application of biological deep litter in pig farming, the normal immune process cannot be reduced.Especially for large-scale pig farms, it is particularly important. However, a number of antibiotics and other drugs can be gradually reduced. The decrease can reach more than 50% than before. If this technology is used in large-scale pig farms under normal operation, drug usage will be drastically reduced in half a year


If the bedding is made of only one composition, it is easy to become harden into pieces. Therefore, it needs people to turn it, then virtually the amount of labor is increased. Therefore, resistance to rotting materials is the best choice as bedding to prolong the use of deep litter.

5.Differences and features of deep litter for all animals

Production methods and steps are the same ,different Reference data as follows:

animal speciesBedding Thicknessquantity/10㎡microbial agent
Pigs, cattle, sheep80CM1.5T1KG
Chicken, duck, goose40CM0.75T2KG

So, that was all for this deep litter method.
