Hey everyone, Feed Additive

Let’s cut to the chase: as a feed additive supplier, I get asked this question all the time, “Can your feed additives actually make animals less sick?” It’s not just a random question—farmers, feed mill operators, even vets are tired of dealing with antibiotic resistance, sky-high vet bills, and the stress of watching livestock or poultry go down with something preventable. Let’s break this down like we’re chatting over a coffee, no jargon, just real-world stuff that matters.
First, let’s set the scene. A few years back, farmers relied heavy on antibiotics in feed to prevent disease. But regulators around the globe—US, EU, even parts of Asia—started phasing that out because overuse led to superbugs that don’t respond to meds. Now, the spotlight’s shifted to alternatives, and that’s where our feed additives come in. But don’t just take my word for it; let’s look at what science actually says.
Take gut health, for example. 70% of an animal’s immune system lives in their gut—fact, not a marketing line. If the gut’s out of whack, bad bacteria run wild, and diseases like E. coli or necrotic enteritis in chickens pop up left and right. Our yeast-based direct-fed microbials (DFMs) work by boosting the good bacteria, like Lactobacillus, that line the gut wall. A 2022 study in Poultry Science found that broilers fed these DFMs had 22% lower incidence of necrotic enteritis than those on a standard antibiotic-free feed. That’s not a small number—for a farmer with 10,000 birds, that means fewer culls, less vet time, and way more profit.
Then there’s organic acids, which are super common in our products but misunderstood. A lot of folks think they’re just for preserving feed, but no—they actually lower the pH in the stomach, which kills off harmful pathogens before they even get to the gut. We recently did a trial with a swine farm in Iowa; we added our blend of formic and propionic acids to grow-finish pigs, and over 6 months, their incidence of diarrhea (a big one in young pigs) dropped 30%. That’s huge because diarrhea in piglets can wipe out entire litters if it’s not caught fast.
Wait, but what about ruminants? Cows, sheep, goats—their digestive systems are totally different from pigs or chickens. Our phytogenic additives (that’s plant-based stuff, like oregano and cinnamon extracts) help reduce methane, but also keep their rumen microbes balanced. A 2021 study from the University of Wisconsin found that dairy cows fed these phytogenics had 15% fewer cases of mastitis, which is a painful udder infection that leads to lost milk and culling. Why? The extracts have antimicrobial properties that target the bad bacteria without messing up the good rumen bugs.
But hold on—this isn’t a magic bullet. A lot of suppliers will tell you their additives fix everything, and that’s just not true. We always tell our clients: feed additives work best when they’re part of a whole management plan. You can’t just throw an additive into a dirty barn and expect no disease. The animals need clean water, balanced feed, proper ventilation, and good biosecurity. Our job is to support that plan, not replace it.
I’ve seen too many farmers get burned by cheap, low-quality additives that don’t do squat. A guy I know in Ohio bought a batch of “immune boosters” online, and his 500 head of cattle still got respiratory disease last winter. Why? That product was just sugar and filler—no active ingredients. That’s why we test every single batch of our additives at third-party labs. Our DFMs have a guaranteed count of live bacteria (no dead ones, which is a scam), our organic acids are food-grade and calibrated for specific animal ages, and our phytogenics are extracted with methods that keep the active compounds intact, not just leftover plant dust.
Another point: stress. Animals get stressed from transport, weather changes, overcrowding—all things that weaken their immune system. Our omega-3 fatty acid additives (from algae, not fish) help reduce that stress response. A 2023 trial with transporting market hogs found that those fed our omega-3 blend had 28% lower rates of respiratory disease after being hauled 8 hours. That makes sense—when an animal’s stressed, their cortisol level goes up, which suppresses immunity. The omega-3s bring that cortisol back down to normal, so their body can fight off germs.
But let’s be real, there are limitations. Feed additives can’t fix genetic issues—if you have a breed of chickens that’s prone to a certain virus, an additive won’t change that. And they’re not cheap, but when you weigh the cost against vet bills, dead animals, and lost production, they pay for themselves fast. Take that Iowa swine farm I mentioned earlier: they spent $0.70 per pig per month on our acid blend, but saved $2.10 per pig in vet costs and feed wasted from diarrhea. That’s a no-brainer.
So why do some people say “feed additives don’t work”? Mostly because they’re using the wrong ones, or using them wrong. A lot of farmers don’t follow the dosage instructions—you can’t give a chicken a human dose of a phytogenic extract and expect results. Or they mix it wrong in the feed, so some birds get too much and some too little. We offer free training to all our clients on how to properly incorporate our additives into their feed programs, and that’s a big part of our value as a supplier.
I also want to talk about antibiotic resistance again. That’s a big deal for the whole industry. If we can reduce disease without relying on antibiotics, we’re not just helping farmers—we’re helping public health. The WHO says antibiotic resistance kills 700,000 people a year, and animal agriculture is a big part of that. Our additives are a way to break that cycle. I’ve had a few vets tell me they now recommend our products instead of antibiotics for preventative care, which is exactly what we’re here for.
Now, I know a lot of you are skeptical, and that’s fair. I’ve been in this game for 12 years, and I’ve seen every gimmick come and go. The ones that stick are the ones backed by solid science, not just fancy packaging. That’s why all our products have data sheets from university trials, and we’re happy to share them with anyone who asks. We also do small-scale trials for new clients—test our additive on a small group of animals first, before committing to a big order. That way, you can see the results for yourself, no risk.
At the end of the day, the goal is the same for all of us: healthy animals, happy farmers, safe food for people. Feed additives aren’t a silver bullet, but they’re a critical tool in the toolbox, especially now that antibiotics are on the way out. We’re always working on new products—last year, we launched a probiotic specifically for goat kids that reduced scours by 35% in our trial, and this year we’re testing a blend for turkey poults to prevent blackhead disease.
If you’re a farmer, feed mill owner, or vet looking to cut down on animal disease, reduce vet costs, and move away from overusing antibiotics, we’re here to help. We don’t do one-size-fits-all—every operation is different, so we’ll work with you to build a feed additive plan that fits your animals, your budget, and your goals. Whether you’re raising 50 head of cattle or 500,000 broilers, we’ve got the science-backed products and the support to make it work.
If you want to chat more, see trial data, or talk about custom blending for your feed, just reach out. We’re here to answer questions, no sales pressure, just real advice from people who actually work in the industry.
