Poultry ProBiotic XL is a concentrated Bacillus poultry probiotic, a direct-fed microbial (DFM) feed additive for commercial flocks. The non-toxigenic, spore-forming strains come as a dry powder at 50 billion CFU/g, dosed in feed at the mill or in drinking water, and used across broilers, layers, breeders, turkeys, and specialty poultry.
In the gut the Bacillus strains produce protease, amylase, cellulase, phytase, and chitinase, enzymes that act on the protein, starch, fiber, and phytate in corn, soy, and wheat rations. Published research on Bacillus DFMs in poultry is summarized in the Details tab. We cite it to describe the category, not as a performance claim for this product.
Poultry ProBiotic XL is a feed additive, not a medication. It is not intended to diagnose, treat, cure, or prevent any disease in poultry, and it contains no antibiotics, so it fits antibiotic-free (NAE and RWA) program specifications.
At a glance
A poultry probiotic is a feed additive that delivers live, beneficial microbes to the bird's digestive tract. In commercial feed the category is called a direct-fed microbial, or DFM. Poultry ProBiotic XL is a concentrated, non-toxigenic, spore-forming Bacillus DFM supplied as a dry powder at 50 billion CFU/g.
Bacillus spores are dormant and heat-tolerant, so they hold their count through feed manufacturing and storage, then germinate in the gut. The strains grow there, compete with other microbes for space and nutrients, and produce enzymes that act on the feed itself.
Most of what comes up in a search for probiotics for chickens is retail: small bags and scoops for backyard coops. Poultry ProBiotic XL sits in the other lane. It is a commercial poultry probiotic sold in bulk pails and drums to integrators, feed mills, and distributors, and dosed by the gram per metric ton of feed or per 100 gallons of water.
If you keep a backyard flock, a retail product is the practical choice. If you formulate feed or run houses at scale, this page is for you.
The working mechanism is enzymatic. In the gut, the Bacillus strains produce five enzymes, each aimed at a component of a standard corn, soy, or wheat ration:
What Bacillus DFMs have done in controlled trials is covered in the research section below. We make no performance claims for Poultry ProBiotic XL itself.
Concentration decides what a DFM costs to run. At 50 billion CFU/g and a broiler inclusion rate of 25 g per metric ton of feed, one 10 kg (22 lb) pail treats 400 metric tons. Custom concentrations are available for formulators who want different dosing math.
The powder holds stable CFU counts for 2 years at room temperature and 3 years refrigerated.
Both routes work, and many operations use each at different phases.
It is also compatible with hatchery spray and gel application. Full dosing tables are in the Specifications tab.
A direct-fed microbial is the feed-industry term for a product that delivers live, naturally occurring microbes through feed or water. In practice a commercial DFM differs from a retail poultry probiotic in three ways: it states its CFU per gram, it is dosed by weight per ton rather than by scoop, and it ships with an SDS and tech sheet for mill use. Poultry ProBiotic XL is built to that standard, and both documents are on this page.
Poultry ProBiotic XL is used across bird types and production phases:
Poultry ProBiotic XL contains no antibiotics and no medicated ingredients, so it fits antibiotic-free, No Antibiotics Ever (NAE), and Raised Without Antibiotics (RWA) program specifications. Many antibiotic-free programs include a Bacillus DFM in the ration; the published reviews cited below cover that practice in detail.
For integrators and feed mills the practical questions are stability and logistics. The spore form survives standard feed manufacturing and storage. The powder blends with standard mill equipment, and packaging runs from 22 lb (10 kg) pails to 340 lb (155 kg) drums. Poultry ProBiotic XL is produced in the U.S. with domestic and international supply.
There is a substantial peer-reviewed literature on Bacillus direct-fed microbials in poultry. Grant, Gay, and Lillehoj (2018), in Avian Pathology, review controlled trials of Bacillus species as antibiotic alternatives in poultry, including reported effects on growth and feed conversion. Mingmongkolchai and Panbangred (2018), in the Journal of Applied Microbiology, review Bacillus probiotics across livestock and the spore properties that suit them to feed use.
Results in that literature vary by strain, dose, diet, and management, and the findings belong to the studies, not to any one commercial product. We cite the research to describe the DFM category, not as a performance claim for Poultry ProBiotic XL.
Poultry ProBiotic XL is a feed additive. It is not a medication, an antibiotic, or a veterinary drug, and it is not intended to diagnose, treat, cure, or prevent any disease in poultry. If birds are sick, involve your veterinarian. Some searches ask for probiotics as a poultry medicine; a probiotic is not a medicine and should not be bought as one.

The published literature on Bacillus DFMs in poultry, including Grant, Gay, and Lillehoj (2018), reports effects on growth and feed conversion that vary by strain, dose, diet, and management. Those findings belong to the cited studies. Poultry ProBiotic XL is a feed additive, and we make no FCR or performance claim for it. If you have a broiler trial you would like us to reference, send it over.
No. Poultry ProBiotic XL is a feed additive, not a medication, antibiotic, or veterinary drug. It is not intended to diagnose, treat, cure, or prevent any disease in poultry. If birds are sick, involve your veterinarian. A probiotic is not a poultry medicine and should not be bought as one.
Yes. It is used across broilers, layers, breeders, turkeys, and specialty poultry, through starter, grower, and finisher phases or as continuous inclusion over a full production cycle. Dosing scales by feed tonnage or water volume, so the same powder covers different bird types and flock sizes.
Both routes work. In feed, blend at the mill: the broiler guideline is 25 g per metric ton for weeks 1 to 6, then 15 g per metric ton. In water, mix a stock solution and meter it through the line: 1 g per 100 gallons (378 L) daily for weeks 1 to 6, then 0.5 g per 100 gallons. It is also compatible with hatchery spray and gel.
Yes. It contains no antibiotics and no medicated ingredients, so it fits antibiotic-free, No Antibiotics Ever (NAE), and Raised Without Antibiotics (RWA) program specifications. Many antibiotic-free programs include a Bacillus DFM in the ration.
Poultry ProBiotic XL is a dry powder at 50 billion CFU/g. The spore form holds stable CFU counts in storage and blends easily into feed or water. Custom concentrations are available on request.
Blend the powder into feed at the mill, or mix it into a stock solution for water dosing. It works with standard mill and water-line equipment and needs no specialized gear. See the Specifications tab for dosing tables.
Yes. It is available in bulk pails and drums and in wholesale supply for integrators, feed mills, and commercial poultry operations. Send us your volumes and we will size the order.
