A farmer's wife came with a gift. Because Helmut Schirmbrand—our father and the founder of KALKMEISTER—had helped her with a homemade paste. For a sick cow. And that, even though he only wanted to stop by briefly. That's our dad. And that's also the story of this article: how a simple volcanic mineral can change life on a cattle farm—from the calf box to the slurry pit.
I remember many conversations with my father where he said he would love to buy all weak calves. He was so sure that we could heal them and make them viable with zeolite. This absolute conviction—he didn't get it from books. It came from years of observation, from conversations with zeolite pioneers and farmers, and from a deep respect for what nature gives us.
And the beautiful thing is: he was right.
What farmers instinctively feel
When you pick up STALLKRAFT bedding for the first time, you immediately notice: this is different. Not dusty, not heavy. Fine, soft, with a delicate herbal scent—peppermint, fennel, lavender. And farmers always tell us: they pick up the bedding, rub it between their fingers and say—you can feel the quality immediately. This is something special.
Interestingly, only the animals truly smell the herbal scent. For us humans, it's delicate. But cows that stand on STALLKRAFT bedding for the first time often react immediately—they lick, they sniff, they relax. This is no coincidence. This is zoopharmacognosy (= the natural self-medication of animals, who instinctively recognize what is good for them). See also Prof. Dr. Karl Hecht on this.
The real challenges in cattle farming
Cattle farming is one of the most demanding tasks in agriculture. Costs are rising, price pressure is enormous, and animals need more attention than ever before. The most common problems we hear from farmers:
Mastitis (= udder inflammation) is still the most expensive disease in dairy farming worldwide. It costs money—through discarded milk, veterinary costs, antibiotics, working time, and in the worst case, the loss of the animal. Many farms struggle with it for years.
High cell counts (= SCC, Somatic Cell Count—a measure of udder health; the higher, the more inflammatory processes in the udder, the worse the milk quality) are often the result of poor barn climate and wet cubicles. Those with high cell counts cannot deliver milk, or cannot deliver it completely—which hits them hard economically. No one wants a "millionaire" in this context.
Ketosis (= dangerous metabolic disease after calving, where the cow has too little energy and breaks down its own fat reserves—can lead to liver failure) and parturient paresis (= milk fever, life-threatening calcium deficiency shortly after birth) are among the most common diseases around calving.
Mortellaro (= digital dermatitis, a contagious claw disease caused by bacteria, which often becomes chronic and is difficult to treat) costs time, money and stresses the animals.
Calf diarrhea is still one of the most common causes of death in young animals—especially in the first weeks of life.
And then there are the things that are less talked about: mold in feed, mycotoxins (= mold toxins), aggressive bulls with open sores, skin diseases during housing changes. All this costs nerves, time, and money.
Zeolite helps with all of this—from the inside and the outside.
What zeolite does in the bovine body—recent studies from veterinary journals
Metabolomics study, University of Zagreb 2021
This is one of the most scientifically sophisticated studies on zeolite in dairy cows ever published. Maity et al., published in the journal Metabolites (MDPI), investigated 16 high-yielding Holstein cows—8 with zeolite supplementation, 8 as a control group—using state-of-the-art methods: metabolomics (= the analysis of all metabolic products in the blood) and proteomics (= the analysis of all proteins in the blood). 64 differentially expressed proteins and 21 different metabolites were identified.
The result: Clinoptilolite zeolite restores the energy balance (= the balance between energy intake and consumption) in high-yielding dairy cows after calving. It reduces the negative energy balance (= NEB, the critical phase where the cow consumes more energy than it takes in) and thus simultaneously lowers the risk of ketosis, mastitis, and fatty liver.
„Dietary zeolite clinoptilolite supplementation restores energy balance in high yielding dairy cows." — Maity et al. (2021), Metabolites, DOI: 10.3390/metabo11120842
New study on reproduction and colostrum 2023
A 2023 Journal of Advanced Veterinary and Animal Research paper examined Holstein cows that received zeolite in the pre-calving period. The result: improved reproductive parameters after calving, better colostrum quality (= first milk after birth, crucial for calf immunity), and better body condition score (= BCS, a measure of the cow's nutritional status).
Mastitis study — Gračner et al., MDPI Animals 2020
78 dairy cows, divided into a zeolite group and a control group. Milk samples were examined on days 7, 25, 45, and 75 after calving. The zeolite group had only 27 infected udder quarters in 14 cows—the control group had 59 infected udder quarters in 24 cows. The risk of udder infection was 1.96 times higher in the control group.
„Cows from the CON group had a 1.96 times higher risk of intramammary infection than cows from the CPL group." — Gračner et al. (2020), MDPI Animals, DOI: 10.3390/ani10020202
Cell counts and milk yield — Ural 2014
A study directly showed: Zeolite supplementation improved both milk yield and somatic cell count (= SCC)—both simultaneously. Less inflammation, more and better milk.
Large field study — Katsoulos et al. 2006, Veterinary Record
52 Holstein cows, divided into three groups. The group with 2.5% clinoptilolite produced 9,273 kg of milk over 305 days—that's 765 kg more than the control group with 8,508 kg. At the same time, there was only 1 case of ketosis instead of 7 in the control group. Liver values remained normal in all animals—zeolite had no negative effects.
Calf study — University of Thessaloniki, Leipzig 2011
84 newborn calves in three groups. The zeolite groups had significantly higher antibody concentrations after 12, 24, and 48 hours—stronger immunity from birth. In the first 6 days, 7 control calves had E. coli diarrhea—in the zeolite groups, only 3. Body weight was significantly higher in the zeolite groups at the end of the experiment (day 60). And the rumen wall of the control animals showed chronic inflammation after slaughter—in the zeolite animals: no changes.
What farmers report from practice
"For the calves, I add half a tablespoon of zeolite to their feed with each meal or one tablespoon once a day. Since then, I've noticed that they gain weight much faster, don't have diarrhea, and are simply fitter. They've been very robust ever since."
"When we moved the small bulls, we always had the problem that they got skin diseases. Ringworm or fungal infections with bald spots. And since I now regularly spread STALLKRAFT, that's gone. When restocking, the barn is practically cleaned and purified. The diseases are eliminated. No more bald spots. And the smell in the barn is much better. And I'm totally convinced."
And then, almost incidentally: "And I mix zeolite with organic apple cider vinegar to a paste and put it on the udder. That works really well for udder inflammation."
"We are a dairy farm. Therefore, udder health is very important to me. The bedding keeps the cubicles dry and the zeolite is anti-inflammatory and reduces germs. The purer and more hygienic it is, the less germ pressure there is on the udder. The healthier the animals are. And the cell count of the milk is good."
Leopold Tazreiter, Neustadtl/Donau — Cell count from 200,000 to 70,000"The best thing is that I can deliver every liter of milk. Because we don't have to select any animals, the milking work is also much faster."
"Since we started using STALLKRAFT bedding, the cell count in cows has dropped to 70,000. That's very, very little. We used to always be at 150-200,000."
And at the same time:
Herbert Grossauer, Maria Neustift — Animal welfare seal and clever economics"The risk of udder inflammation has decreased significantly. We haven't had a single case of mastitis in our barn. We used to always have the claw disease Mortellaro in the barn. After we let the cows walk through a lime bath after the milking parlor, it has significantly decreased."
"By adding lime, I save straw in the cubicles. The liquid is absorbed, so I need to bed less straw. It is more hygienic and smells better. And Mortellaro is no longer an issue because we also lime in the barn."
"If you save on quality, it will cost you dearly! Because we have been regularly liming with finely powdered slurry lime for years, we only need 300-400 kg per hectare. If you stop liming, it gets expensive because you have to start all over again. It's important to do it continuously."
Reinhard P. — Pigs and cattle, one farm, one experience"We mix TIERKRAFT Zeolith with organic apple cider vinegar to form a paste. This is applied to the udder. Works great! Mastitis is a thing of the past."
"By regularly sprinkling a shovel of lime over the floor, not only is the ammonia content in the manure bound, but also the odor development is significantly reduced. The result is a noticeably cleaner and fresher environment."
And then something surprising happens:
"Interestingly, the pigs seem to appreciate this addition—they readily pick up the lime from the ground."
The same applies to cattle. Animals know what's good for them.
F., Schönau — From the barn to the slurry pit and onto the fieldOrganic farm Erdinger, Gerda and Karl"We use STALLKRAFT as a slurry additive directly in the slurry pit. The slurry is much more homogeneous and easier to spread. There is less stench. Everything flows more easily, which also means less work. We are now also starting to use it as bedding. As it were, one step earlier in the cycle. Because the decomposition then already begins in the barn, where NH3 is already bound and mites and molds no longer stand a chance."
"I have only used STALLKRAFT in the barn for a few days now, and it is truly incredible how quickly the unpleasant odor is almost eliminated. I can only recommend it to every animal owner. Not only for the neighbors, but also for ourselves, it is more pleasant."
The mastitis paste — a special tip that many already know
A zeolite-apple cider vinegar paste applied externally to the udder—this is a tip that has long been passed on among experienced farmers. And it works. Why?
Zeolite forms a protective film on the skin surface. It actively absorbs wound secretions and inflammatory products—and when the paste dries after a few hours and falls off by itself, it carries these harmful substances away. New germs from the barn environment cannot penetrate the inflamed tissue during this time.
Organic apple cider vinegar lowers the pH value (= acidity) of the paste to a slightly acidic environment—in which pathogenic bacteria such as Staphylococcus and coliform germs can hardly multiply.
Clinoptilolite also has antibacterial properties—this has been proven in laboratory studies (Haydel et al. 2008: Clay minerals inhibit a broad spectrum of antibiotic-resistant bacteria).
How to use the paste: Mix STALLKRAFT Zeolith with organic apple cider vinegar to a creamy paste. Apply to the affected teats and udder—ensure intensive contact by rubbing it in. Let it act for a few hours until the paste dries and falls off by itself. Repeat several times daily until healing is complete.
And another tip from experienced farmers: Even after calving, when the udders are large and heavy—massage it in preventively. This is not an effort. This is care.
AM+PLUS Active Microorganisms — the third power in the cattle barn
Zeolite and lime are strong. They become even stronger in combination with AM+PLUS Active Microorganisms—produced at the Loidholdhof in Upper Austria.
What AM+PLUS microorganisms achieve in the cattle barn:
It starts the healthy fermentation process (= natural conversion of organic substances by microorganisms) already in the barn. This means less rot, less odor, a better barn climate—and slurry that is already pre-activated when it reaches the field. The slurry becomes more homogeneous, easier to stir, and flows more evenly from the pit.
Bernhard Keplinger, organic farmer from Bad Leonfelden, reports: "Since then, the climate in the barn has improved tremendously. The smell of the slurry is better, stirring is much easier, and we no longer have flies in the barn. This year we had almost tropical weather and neighboring farms couldn't get rid of the flies. We had almost none. Even the vet asked us what we were doing in the barn."
AM+PLUS in the cattle barn — how to use it:
As barn air nebulization: 0.2 liters of AM+PLUS to 10 liters of water, spray into the barn air and onto the bedding areas at least 3 times a week. This reduces odor, germs, and flies simultaneously.
In the slurry: 0.1 liters of AM+PLUS per cubic meter of slurry—stir well, let ferment for 10 days before application. The result: higher quality, more nutrient-rich slurry.
GÜLLEKRAFT N-FIX — Retaining nitrogen in slurry
Every kilogram of nitrogen that escapes as ammonia (NH₃) into the air is a lost kilogram of fertilizer. And it is a burden—for neighbors, for the environment, for regulatory requirements.
GÜLLEKRAFT N-FIX binds this ammonia nitrogen in the slurry before it escapes. The nitrogen remains bound in the liquid and is fully available to the plants during application.
And here's something important to know: GÜLLEKRAFT does NOT settle in the slurry. This is one of the most common objections we hear—and it's not true. Due to our tribomechanical grinding process, the particles are so fine that they remain suspended in the slurry. 20 kg of STALLKRAFT or GÜLLEKRAFT per m³ of slurry is enough to achieve a homogeneous (= uniformly mixed) slurry that does not separate.
The result: up to 80% nitrogen utilization in the field—significantly more than without treatment. What's good for the soil is also good for the wallet—and for the neighborhood.
Frequently asked questions from practice
Can STALLKRAFT bedding also be eaten?
Yes — and this is intentional. STALLKRAFT bedding is high-quality feed lime. The organic herbs have a stimulating effect on digestion and well-being. Zeolite optimizes the feed from within. If a cow licks bedding, she does so for a good reason.
How much should I use?
The lying area must always be dry. 200–300 g per m² daily — for cubicles, adjust accordingly for deep litter areas. Many farms use the feed mixer: 700 kg straw, 1,000 kg STALLKRAFT, 600 liters of water — and the perfect mix is ready.
Does the bedding have a disinfecting effect?
Not in the chemical sense. Conventional disinfectants have a pH value of over 10 and are corrosive. STALLKRAFT has a pH value of 7–9 and dries naturally. At a pH value of 8, NH₃ escapes — with STALLKRAFT, this pH value is maintained and ammonia is bound instead of released. This is the crucial difference.
What to do about Mortellaro?
From the inside: TIERKRAFT Zeolite as a feed additive. From the outside: set up a lime bath and let the cows walk through STALLKRAFT bedding after milking. Hooves dry, germs are bound, healing begins.
Does GÜLLEKRAFT settle in the slurry?
No. This is one of the most important features of our product. Due to the tribo-mechanical grinding process, the particles are so fine that they remain suspended and distribute evenly in the slurry.
Application & Dosage — as simple as possible
STALLKRAFT Bedding: 200–300 g/m² daily. Always keep the lying area dry. For Mortellaro: create a lime bath, let cows walk through it after milking.
TIERKRAFT Zeolite as a feed additive: max. 1–2% of the total daily ration, mix into moist feed. Particularly valuable in the last 4 weeks before calving and in the first weeks of lactation.
Zeolite-Apple Cider Vinegar Paste: Mix STALLKRAFT with organic apple cider vinegar to a creamy paste, apply to affected udder areas, repeat several times daily.
AM+PLUS Stable Air: 0.2 L per 10 L of water, spray at least 3 times weekly.
AM+PLUS Slurry: 0.1 L per m³ of slurry, stir well, let ferment for 10 days.
GÜLLEKRAFT N-FIX: 20 kg per m³ of slurry for homogeneous, nitrogen-rich slurry.
