Can moldy hay make your horse sick? The answer is absolutely yes! Moldy hay is one of the most dangerous threats to your horse's health, causing everything from breathing problems to digestive issues and even reproductive failures. I've seen too many horses suffer because their owners didn't know what to look for - but you're smarter than that!Here's the deal: mold spores in hay can trigger recurrent airway obstruction (also called heaves), which is like asthma for horses. Once your horse develops this condition, you're looking at a lifetime of management. Even worse, some molds produce toxins that can cause colic, weight loss, and in severe cases, organ damage or death.But don't panic! The good news is you can easily protect your horse by learning how to identify bad hay. I'll show you exactly what to look for - from visual clues to smell tests - so you can catch mold before it causes problems. Trust me, taking two minutes to inspect your hay could save you thousands in vet bills down the road!

Why Moldy Hay is a Big No-No for Your Horse
The Silent Killer in Your Barn
You wouldn't eat moldy bread, right? Well, your horse shouldn't eat moldy hay either! Mold spores in hay can wreak havoc on your horse's health faster than you can say "vet bill."
Let me paint you a picture: imagine your horse developing a cough that won't quit, struggling to breathe like an asthmatic kid in gym class. That's recurrent airway obstruction (or "heaves" in horse terms) - and it's no joke. Once it starts, you're looking at a lifetime of management, not a quick fix.
More Than Just a Cough
But wait - there's more! Mold doesn't stop at breathing problems. Those nasty mycotoxins can:
- Upset your horse's stomach (think colic city)
- Cause diarrhea that'll have you mucking stalls nonstop
- Lead to weight loss no matter how much they eat
And here's the kicker - did you know moldy hay can even affect pregnant mares? We're talking unexpected abortions or foals born with defects. That's why checking your hay quality isn't just important - it's critical.

The Farmer's Dilemma
Ever tried timing something perfectly, only to have weather ruin everything? That's a hay farmer's daily struggle. Cutting too early means too much moisture (hello mold!), but cutting too late means losing nutrients.
Here's a fun fact: even the best farmers can't control the weather. One unexpected rain shower after cutting, and bam - you've got the perfect storm for mold growth. That's why choosing a reputable hay supplier matters so much.
Storage: Where Good Hay Goes Bad
Think of hay like a sponge - it soaks up moisture from everywhere. Store it wrong, and you might as well be feeding your horse a science experiment.
Proper storage means:
- Keeping bales off the ground (pallets are your friend)
- Using a barn or shed when possible
- Ensuring good airflow around the bales
And here's a pro tip: even perfectly stored hay can develop mold. That's why visual inspection before feeding is non-negotiable.
Becoming a Hay Detective
The Sniff Test
Your nose knows! Before feeding, give that hay a good whiff. Moldy hay often smells musty - like your grandma's basement after a flood. But here's the thing: any unusual odor should raise red flags.
Funny story - last month I caught a bad batch just by noticing the hay smelled slightly "off." Saved my mare from what could've been a nasty case of colic. Trust your senses!

The Farmer's Dilemma
Let's play a quick game of "Spot the Difference" with your hay:
| Good Hay | Bad Hay |
|---|---|
| Uniform green color | Discolored or dark spots |
| Minimal dust | Excessive dust clouds |
| Clean plant material | Foreign objects or weeds |
See something suspicious? When in doubt, throw it out! Better safe than sorry with your horse's health.
Smart Solutions for Hay Storage
Bale Bags: Not Just Fancy Wrappers
Ever seen those giant hay bag things and wondered if they're worth it? Absolutely! A good ventilated hay bag can be a game-changer, especially if you're traveling or have limited storage.
I personally swear by the Derby Originals extra large cover - it lets the hay breathe while keeping moisture out. Plus, it cuts down on waste, which means more bang for your buck.
Feeders: More Than Just Convenience
Here's a question: why do most people toss hay on the ground? Habit? Laziness? Either way, it's time to break that habit!
Using a proper hay feeder or net:
- Keeps hay cleaner
- Reduces waste
- Helps horses eat in a natural head-down position
Just make sure it's not too high - you don't want your horse inhaling dust like a vacuum cleaner!
When in Doubt, Test It Out

The Farmer's Dilemma
Not sure about your hay's quality? Get it tested! Some tests give instant results right in your barn, while others take a bit longer. Either way, isn't your horse's health worth the extra step?
I recently tested a questionable batch and discovered mold levels that weren't visible to the naked eye. That $50 test potentially saved me thousands in vet bills down the road.
Alternative Feed Options
If local hay quality is consistently questionable, consider alternatives like:
- Compressed hay bales (Standlee's Grab & Go is fantastic)
- Hay cubes
- Complete feed pellets
These options are processed at peak freshness and sealed tight against moisture. Plus, they're super convenient for busy horse owners!
Final Thoughts (But Not Really)
Remember - your horse depends on YOU to be their food safety inspector. A few minutes of checking hay could save months of health problems. Now go give those bales a good once-over before feeding!
And hey - if you ever feel overwhelmed by all this hay talk, just remember: even the most experienced horse owners started somewhere. You've got this!
The Hidden Dangers of Moldy Hay You Never Considered
Your Horse's Gut: More Sensitive Than You Think
Ever wonder why your horse gets gassy after eating questionable hay? That's because their digestive system is way more sensitive than ours. While we might just get a stomachache from bad food, horses can develop serious digestive imbalances that throw their whole system out of whack.
Here's something most people don't realize - mold doesn't just affect the lungs. When those nasty spores reach the gut, they can kill off the good bacteria your horse needs for proper digestion. Suddenly, you've got a horse that's either dropping weight like crazy or looking bloated like a balloon animal. And let me tell you, fixing gut flora takes way longer than ruining it!
The Financial Toll of Cutting Corners
Think saving money on cheaper hay is smart? Let's do some quick math:
| Cost Factor | Good Hay | Moldy Hay |
|---|---|---|
| Initial Price | $8/bale | $5/bale |
| Vet Visits | $0 | $500+ |
| Missed Riding Days | 0 | 10-30 |
See what I mean? That "bargain" hay could cost you way more in the long run. And that's not even counting the emotional toll of seeing your horse suffer!
Beyond the Obvious: Unexpected Mold Hotspots
That One Bale in the Back Corner
You know that bale that's been sitting untouched for weeks? Yeah, that's prime mold real estate right there. Here's the thing - mold grows fastest when we're not looking. Those forgotten bales in dark corners might look fine on the surface, but flip them over and you could find a fuzzy surprise.
I learned this the hard way last winter when I grabbed what looked like a perfectly good bale from the back of the stack. Turns out the bottom was completely molded where it touched the ground. Now I make it a habit to rotate my hay stock like groceries - first in, first out!
The Deceptive "Just a Little" Mold Problem
"It's only a little spot - I'll just pick that part out." Sound familiar? Here's why that's risky business: mold is like an iceberg. What you see on the surface is just a fraction of what's really there. Those visible spores mean the entire bale could be contaminated, even if it doesn't show yet.
Think about it this way - would you eat bread with "just a little" mold? Exactly! Your horse deserves the same standard. When I find any mold, the whole bale goes straight to the compost pile. No exceptions.
Proactive Prevention: What the Experts Do Differently
The Humidity Factor Everyone Ignores
Did you know hay can absorb moisture from the air itself? That's right - even in perfect storage conditions, high humidity can cause problems. This is why savvy horse owners invest in simple tools like hygrometers to monitor their barn's moisture levels.
Here's a cool trick I picked up from an old-timer: place a small fan near your hay storage to keep air circulating. Not directly on the bales - you don't want to dry them out too much - but nearby to prevent stagnant, humid air pockets. It's made a huge difference in my hay's shelf life!
The Buying Strategy That Saves Headaches
Ever notice how some people seem to always get great hay while others constantly struggle? There's actually a method to the madness. Smart buyers:
- Purchase hay right after cutting season when quality is highest
- Build relationships with trusted growers
- Ask for "horse quality" specifically (not all hay is equal!)
And here's a pro tip: always ask to see the hay before buying in bulk. A good farmer will gladly show you their storage facility and let you inspect samples. If they hesitate, that's your red flag right there!
When Disaster Strikes: Handling Mold Exposure
The First 24 Hours: Damage Control
Uh-oh - your horse just ate some moldy hay. Now what? First, don't panic (easier said than done, I know). Immediately remove all suspect hay and switch to a clean source. Then monitor closely for:
- Changes in breathing patterns
- Appetite fluctuations
- Manure consistency changes
Here's something most people don't think about - offer plenty of fresh water to help flush out any toxins. I keep electrolytes on hand for exactly this situation. And of course, if symptoms appear, call your vet immediately!
Long-Term Recovery: More Than Just Good Hay
So your horse had a mold exposure incident - now you've got to think about rebuilding their health. This isn't just about switching to clean hay (though that's crucial). You'll want to support their system with:
- Probiotics to restore gut health
- Extra vitamins (especially E and selenium)
- Light exercise to keep lungs clear
I learned this regimen from my vet after a scare last year, and let me tell you - it works wonders. My mare bounced back faster than I expected, and her coat looked better than ever!
The Psychological Impact We Never Talk About
Owner Guilt: It's Real
Here's the thing nobody prepares you for - when your horse gets sick from bad hay, you'll probably feel terrible. I sure did! But beating yourself up won't help your horse recover. Instead, channel that energy into becoming a hay expert.
Remember - even the most experienced horse people make mistakes. What matters is that you caught the problem and are fixing it. Cut yourself some slack and focus on moving forward!
Building Confidence in Your Hay Choices
Nothing feels better than knowing you're feeding your horse the absolute best. That confidence comes from education and experience. Start small - maybe attend a hay quality workshop or shadow an experienced buyer for a day.
You know what surprised me? How much fun learning about hay can be! There's a whole science to it, from understanding different grass types to learning how weather affects curing. The more you know, the more empowered you'll feel making those feeding decisions.

FAQs
Q: How can I tell if my horse ate moldy hay?
A: Watch for these warning signs your horse may have eaten moldy hay: coughing, nasal discharge, or labored breathing (signs of respiratory issues), colic symptoms like pawing or rolling, unexplained weight loss despite normal eating, or diarrhea. Pregnant mares might abort or deliver unhealthy foals. The tricky part? Some symptoms take time to appear. That's why prevention through careful hay inspection is so crucial. If you suspect mold exposure, remove the questionable hay immediately and consult your vet.
Q: What does moldy hay look and smell like?
A: Moldy hay often has visible discoloration - look for dark spots, grayish patches, or an overall dull appearance compared to fresh green hay. When you break open a bale, check between flakes where moisture hides. The smell test is equally important: good hay smells fresh and slightly sweet, while moldy hay smells musty or mildewy - like damp basement. Pro tip: if the hay seems unusually dusty when you handle it, that's another red flag for potential mold issues.
Q: Can I salvage slightly moldy hay by airing it out?
A: Here's the hard truth: there's no safe way to "fix" moldy hay. While airing might reduce surface mold temporarily, it won't eliminate dangerous mycotoxins that have already developed. I know it's tempting to try saving money, but is it worth risking your horse's health? When in doubt, throw it out! Better to lose a bale than your horse. Consider alternative forage sources like compressed hay cubes or pellets if you're struggling with hay quality issues.
Q: How should I store hay to prevent mold growth?
A: Proper storage is your first line of defense against mold. Always keep hay off the ground using pallets or a waterproof barrier. If possible, store in a well-ventilated barn or shed. No barn? At least use a breathable tarp (like Derby Originals covers) that allows moisture to escape. Stack bales loosely to promote airflow, and never stack directly against walls. In humid climates, consider using moisture-absorbing products. Remember: even perfect storage can't fix hay that was baled too wet, so always buy from reputable suppliers.
Q: Are hay nets or feeders better than feeding on the ground?
A: Absolutely! Using a quality hay net or feeder serves three important purposes: it keeps hay cleaner, reduces waste, and most importantly - helps prevent respiratory issues by minimizing dust inhalation. Just make sure to hang it at the right height (horse's head should be at or below withers level) to encourage natural grazing position and proper drainage of airways. I recommend slow-feed nets for extended chewing time and better digestion. It's one of the easiest changes you can make for your horse's health!
