Algae, humates and chitin — new additive directions
Alongside classic additives, newer groups are appearing that are only winning their place in poultry nutrition. These are algae and seaweed, humic acids and humates, and chitin and chitosan. Each works differently and each is at a different stage of research. We explain what is known today, what to expect from them and where evidence is still missing to make strong promises.

The world of feed additives doesn’t end with probiotics, organic acids or herbs. Increasingly there’s talk of three newer groups: algae and seaweed, humic acids and humates, and chitin and chitosan obtained from insects among others. What they share is that they promise support for gut health and immunity, but they’re at a fresher stage of research than classic additives. They’re worth knowing — treated cautiously, with curiosity but without excessive expectations.
Why reach for new additives?
The motivation is similar to other natural additives: a healthier gut, better immunity and cutting antibiotics. Algae bring polysaccharides, iodine and compounds supporting immunity. Humates are meant to support the gut, bind some toxins and improve litter quality. Chitin and chitosan act antibacterially and prebiotically. These are fresh, promising directions, but results vary — they’re best treated as a supplement to proven nutrition and hygiene fundamentals, not as their substitute.
Algae, humates and chitin in brief
These are different additives with different action and different levels of documentation — all they share is being newer and less recognised.
Algae and seaweed
Marine algae and seaweed bring polysaccharides, iodine, minerals and compounds supporting immunity. They’re sometimes used as an additive meant to improve gut condition and overall flock immunity. It’s a broad group, so the action depends heavily on the algae species and the way it’s processed.
Algal polysaccharides
Part of the algae effect is attributed to their specific polysaccharides, which can act as a prebiotic and influence the immune system. It’s one of the most studied aspects of this group. The results are promising but still need confirming under production conditions.
Humic acids and humates
Humic acids and their salts, the humates, are substances derived from natural organic matter. In poultry nutrition they’re linked with gut support, the ability to bind some toxins and improved manure quality. Some studies indicate they may favour drier litter, which indirectly supports foot condition.
Toxin binding and drier litter
Humates are credited with the ability to bind some harmful compounds in the digestive tract and a favourable effect on manure consistency. Drier manure and litter mean less ammonia and better conditions for the feet. It’s one of the more practical arguments for this group, though effects depend on dose and preparation.
Chitin and chitosan
Chitin is the building block of insect shells, and chitosan is its derivative. As insect protein in feed develops, interest in these compounds grows. They’re credited with antibacterial and prebiotic action — support for beneficial gut microflora. It’s a fresh, interesting direction, still intensively researched.
Status and caution
Many of these additives are at an early stage of introduction, and their status as registered feed additives varies — it’s worth checking a given preparation in the EU register. The scientific evidence is promising but often incomplete. So treat these groups as a supplement, follow the research and don’t make strong promises based on them.
New additives step by step
- 1
Get the basics right first
Before reaching for algae, humates or chitosan, make sure the basics are in order: good feed, clean water, dry litter and hygiene. New additives work best where the foundations are already there. Without them, no additive, however trendy, will make a difference.
- 2
Check what the studies actually show
With newer groups it’s easy to find overblown promises. Before you invest, look for reliable scientific reviews for the specific group — algae, humates or chitin. Note whether the effects were confirmed under production conditions or only in single trials. Caution pays off here.
- 3
Choose a preparation with a clear composition
Reach for products with a legible composition, the algae species or humate source and a content declaration. Check whether the preparation is registered as a feed additive — you can verify this in the EU register. Avoid products promising everything at once with no specifics.
- 4
Test on part of the flock
It’s worth checking a new additive on a limited scale first, for example in one house or flock, before rolling it out everywhere. That makes it easier to see whether it really helps in your conditions. Note the dose, timing and observations so you have something to return to later.
- 5
Watch the gut, litter and immunity
Watch what a given additive is meant to support: gut and manure condition with humates, litter and feet, overall immunity and results with algae or chitin. Real, repeatable improvement is a good sign. No difference means the additive brings no value in your case — and you can drop it.
- 6
Treat them as a supplement, not a miracle
Algae, humates and chitin are interesting, fresh directions, but still a supplement to proven fundamentals, not their substitute. They won’t replace good feed, hygiene or a health programme agreed with the vet. Use them with an open mind but also with distance from marketing promises.
Frequently asked questions about new additives
Do algae in feed really help poultry?add
Algae and seaweed bring polysaccharides, iodine and compounds supporting immunity, and some studies point to a favourable effect on the gut and flock immunity. But it’s a very broad group, and the effect depends on the algae species and the way it’s processed. The results are promising but still need confirming under production conditions, so it’s worth approaching them with curiosity and caution.
What do humic acids and humates give?add
Humates are credited with gut support, the ability to bind some toxins and improved manure quality, which can favour drier litter and better foot condition. It’s one of the more practical arguments for this group. The effects, however, depend on dose and preparation, and the evidence, while promising, can be incomplete — so it’s worth treating them as a supplement to the basics.
What are chitin and chitosan in poultry nutrition?add
Chitin is the building block of insect shells, and chitosan is its derivative. As insect protein in feed develops, interest grows in these compounds, credited with antibacterial and prebiotic action — support for beneficial gut microflora. It’s a fresh, interesting direction, still intensively researched, so for now it’s better treated as an area to watch than a ready solution.
Will these additives replace classic nutrition?add
No. Algae, humates and chitin are newer directions that can supplement nutrition but won’t replace good feed, clean water, hygiene and a health programme. They’re at a fresher stage of research than classic additives, so it’s worth using them sensibly, testing on part of the flock and not making strong promises based on them until they prove out in your conditions.
