Manure is precious – smell equals losses

Farm animal‘s excretement is full of nutrients, as in general the feed is only partially degraded. In most cases, undigested fibre components are directly excreted in the manure and may result in floating layers and a bad viscosity.

jbs güllezusatz: manure is precious – smell equals losses

Odour formation cannot be avoided. Each development of odour indicates a loss in nutrients, as it means that nutrients are evaporating – which is perceived as odour. This includes the formation of volatile ammonia from the transformation of urea as well as the appearance of smelly volatile fatty acids such as butyric and acetic acid.

Our manure additive – jbs güllezusatz – helps control the degradation processes in manure in such a way that both fibrous material and nutrient losses are reduced.

Manure is a precious asset – it pays to enhance it!

Nutrient losses in manure increase the more the manure is moved and the longer it is stored. The bacteria contained in jbs güllezusatz use the manure‘s nutrients to produce and nurture fibre-degrading enzymes. Thus, solids in the manure are reduced, time and effort required for stirring and pumping can be reduced and it is easier to distribute the manure onto the fields.

jbs güllezusatz is a freeze-dried powder containing live microorganisms. It is added to the manure in small amounts. The manner in which the manure is stored (lagoon, concrete silo ...) is irrelevant.
Apply on a fortnightly basis – according to number of animals and volume of manure. Ideally, dissolve the product in water and apply it during stirring – either directly through the slits or via the extraction shaft.
jbs güllezusatz works in all climates and stays active even under ice.


Packed in aluminium pouches containing 500 g each


Store in a cool, dry place – ideally in a fridge. Seal pouch as tightly as possible after opening and sampling (use clips, rubber bands or tape).

jbs güllezusatz does not contain chemical or water-polluting ingredients. jbs güllezusatz may be used to enrich the manure of all types of animals.

Effects on manure

Effect no. 1 – fluidity

The bacteria contained in jbs güllezusatz feed on the nutrients available in manure and produce fibre-degrading enzymes, thus breaking down solids in the manure. This reduces the time and effort required for stirring and pumping. Containers are easier to empty and there is less slurry at the bottom. The manure can be distributed more evenly on the fields.

Effect no. 2 – odour reduction

jbs güllezusatz: effects of jbs güllezusatz on volatile fatty acids

The unpleasant odour of manure which may be noticed by you, your neighbours, or your animals, is significantly reduced. Ammonia is not the only reason for the bad smell of manure – volatile fatty acids (VFA) also create an unpleasant odour.

jbs güllezusatz binds volatile fatty acids, which will later be converted into methane if the manure is used in a biogas plant.

Effect no. 3 – biogas

jbs güllezusatz: trial results on methane yield
Landwirtschaftszentrum Eichhof, agricultural laboratory for Hesse

Effects of jbs güllezusatz on biogas production were determined in a batch trial. Positive effects on gas production could be observed in a fermenter containing manure treated with jbs güllezusatz. An increase in methane yield by 5 % could be measured both with just manure as well as with manure plus maize.

This trial proves that the treated manure provided a higher level of nutrients for the bacteria to transform into biogas in the fermenter.

An increased methane yield saves substrate.
Example: In a 500 kW fermenter, an increase in methane by 5 % means that approx. 1 tonne of maize can be saved per day.

Impressions from farm trials

jbs güllezusatz: uncomplicated application
Impressions at a glance
  • uncomplicated application
  • reduces fibre content (NDF), especially content of undigested fibres (ADF)
  • reduces content of ammonia-N
  • makes stirring a lot easier
  • significantly reduces smell during stirring

jbs güllezusatz was used at a bull fattening farm with the manure being analyzed during the trial period. The manure additive was applied over a period of two and a half months in two virtually identical stables (200 animals in each during the final fattening phase). jbs güllezusatz was dissolved in water on a fortnightly basis and applied in various places of the manure pit. Samples were taken in advance and their ingredients were analyzed by LUFA.

As the animals in the control group were slightly younger than those in the stable with treated manure, the initial values were different – especially regarding dry matter contents. However, the significant differences in the development of certain parameters over the trial period were quite interesting. Feed rations were similar in both stables and remained unchanged during the trial period.

After the fourth application – meaning after approx. 6 weeks – the manure appeared to be more liquid during stirring, and the smell was better in comparison to the control group. Subjectively, these observations grew continuously stronger right up to the last sampling and were also confirmed objectively by analysis.

Dry matter

jbs güllezusatz: dry matter content during trial period

As for the older animals, the initial analysis showed a value of 9.3 %. In the control group, this value was significantly lower: 7.7 % . While this value hardly changed in the control group, the dry matter content decreased continuously in the stable with treated manure. In the end, it was significantly lower than that of the control group: 6.7 % instead of 7.3 %.

Reduces fibre content

jbs güllezusatz: fibre content NDF

Analysis of fibre content (NDF/ADF) confirmed the impression of increased fluidity and viscosity.

jbs güllezusatz: undigested fibres ADF

The content of undigested fibres (ADF) was especially reduced.

jbs güllezusatz: odour formation means nutrient losses !!!

Odour formation means nutrient losses !!!

Odour develops when volatile fatty acids such as acetic or butyric acid, as well as aeriform ammonia, are released.

jbs güllezusatz: content of ammonia-N

The observation of a reduced smell in farm trials fits to the reduced content of ammonia-N. On stirring, less ammonia is released into the environment as the bacteria convert it into a nutrient as which it stays in the manure.
