The active part of lactobacilli, from mill to feeder.

Indifferent to pelleting
Already inactivated: its value does not depend on cells surviving the press.
Supports gut balance
Cell walls and metabolites interact with the gut mucosa and help microbiota balance.
Consistent to the feeder
Same composition from mixer to feeder, batch after batch.

Linkabiome: a postbiotic for feed, from heat-inactivated lactobacilli

Name: Linkabiome
Uploaded: 2026-11-04
Duration: 1 min 7 s
Description: What a postbiotic is, how it differs from a live probiotic, and why the absence of live cells makes pelleting and storage simpler.

A postbiotic is a preparation of inactivated microorganisms, with their components and the metabolites of their fermentation. Linkabiome is not a probiotic: its lactobacilli are no longer alive. That is what makes this postbiotic feed additive indifferent to pelleting and storage.

Species: Poultry, pigs, ruminants, aquaculture
Use: At the feed mill, before pelleting

The problem

Live cells do not like the feed mill

A probiotic has to reach the intestine alive. Between the mixer, conditioner steam, the press and weeks of warm storage, part of the cells do not make it, and the effect varies with them. A postbiotic gets around the problem: its cells are inactivated at manufacture, and what it supplies, cell walls and metabolites, does not depend on their survival.

In poultry as in pigs, this is what the market looks for under the name gut health: an intestine that digests well and a balanced flora. The starter phase, the piglet weaning transition and feed changes put both to the test, and postbiotic solutions for poultry gut health are judged on exactly those moments.

For live lactobacilli in piglets: Linkaflore.

Postbiotic or probiotic

Postbiotic or probiotic: what is the difference?

A probiotic supplies live microorganisms, which must survive to act. A prebiotic supplies substrates, usually fibres, that the animal’s own flora ferments. A postbiotic supplies inactivated microorganisms and what they produced during fermentation: it does not need to survive. Prebiotic, probiotic, postbiotic: three different jobs.

Postbiotic vs probiotic: which is better? The question is badly put, because they do not do the same thing. The postbiotic has stability on its side: it withstands pelleting and storage, and its composition does not vary with cell survival. A live probiotic can settle and ferment in the gut; in return, it needs stricter manufacturing and storage conditions.

In animal feed, both have their place, and Linker offers both routes: the postbiotic Linkabiome for all species, and the live probiotic Linkaflore for piglets.

Heat-inactivated lactobacilli

What are heat-inactivated lactobacilli?

Lactobacilli are lactic acid bacteria, found naturally in the intestine and in fermented foods. To make a postbiotic, they are grown, then inactivated by heat: often called heat-killed lactobacilli, they no longer multiply, but their cell walls and the metabolites produced during fermentation remain.

In Linkabiome, two Lactobacillus strains are grown together, then inactivated along with their fermentation metabolites. This is how a postbiotic based on lactobacillus is made for animal feed.

How do postbiotics work? These components interact with the intestinal mucosa and contribute to the balance of the microbiota: that is the mode of action described for postbiotics. And because nothing in them is alive any more, there is no live cell count to guarantee all the way to the feeder.

The grade

One grade, for all species

Frequently asked questions

What is a postbiotic?

A preparation of inactivated microorganisms and their components, with the metabolites produced during their fermentation. Unlike a probiotic, it contains no live cells: its effect does not depend on their survival. Examples in feed include heat-inactivated lactic acid bacteria such as those in Linkabiome.

Is Linkabiome a probiotic?

No. Its lactobacilli are heat-inactivated: it supplies no live bacteria. For a live probiotic in piglets, see Linkaflore.

Does a postbiotic withstand pelleting?

Its cells are already inactivated, so what it supplies does not depend on their survival through steam, the press or storage.
