Honouring our horses' ancient gut

Welcome to the very first episode of the Happy Horse Nutrition Podcast! 🎙️
If you’ve ever wondered why “normal” modern feeding often leads to issues like colic, ulcers, unpredictable behaviour, poor condition, poor performance or picky eating… this episode is your starting point.

PhD equine nutritionist Dr Nerida takes you back to the horse’s blueprint: 55 million years of evolution as a grazing animal — and shows you the tiny sliver of time our horses have been living the way we keep horses today.

When you understand how the horse’s gut was designed to work, feeding becomes a whole lot simpler (and your horse gets a lot happier and healthier!).

In this episode you’ll walk through the 5 key rules of feeding your horse like a horse:

·       Why forage should be the foundation of every diet

·       How forage and fibre variety supports nutrient intake and gut resilience

·       Why horses need near-constant access to fibre to help protect the stomach from acid

·       The truth about balanced diets (why forage is essential… but often lacking critical nutrients); and

·       The overlooked basics; clean water and salt, and why they directly affect feed intake and colic risk.

This is a practical, science-backed framework, delivered in Dr Nerida’s friendly, matter-of-fact manner, that you can apply whether you have a backyard pony, a performance horse, a racehorse, or a broodmare.

Feeding through drought? Here’s what your horse really needs.
Drought can be overwhelming — but your feeding choices can make all the difference. In this episode, Dr Nerida shares expert, practical advice to help you keep your horse healthy, nourished, and mentally sound through tough times. Learn which hays are safe, how much to feed, and why vitamin E capsules and carrots might just be drought essentials.

Confused about which supplements your horse actually needs? In this comprehensive episode, PhD equine nutritionist Dr. Nerida cuts through the marketing noise to reveal what's essential, what may be useful, and what's likely a waste of money.

Discover why salt is the one non-negotiable supplement every horse must have access to—and why compressed salt blocks might not be the best option. Learn when electrolytes are truly necessary (and the critical water access rule you must follow), plus get the inside story on hoof supplements, gut health products, mycotoxin binders, and bone mineral supplements.

Nerida shares practical insights on vitamin E deficiency in older hay, the truth about most current bacterial probiotics, how joint supplements fall short, and how to spot "snake oil" products that promise everything but deliver nothing. She also explains why feeding supplements at less than the recommended dose—tempting as it is to save money—often means you're just wasting your investment.

The bottom line? A balanced diet does 90% or more of the work in your horse’s diet. But when supplements are needed, knowing which ones actually work and how to use them properly can make all the difference to your horse's health.

Whether you're feeding a backyard companion or a performance athlete, this episode will help you make informed, evidence-based decisions about your supplement budget.

Join PhD equine nutritionist Dr. Nerida as she tackles one of horse owners' most pressing questions: does my horse actually need grain? This comprehensive equine nutrition episode breaks down the science behind horse grain feeding, revealing why most horses don't need grain at all - and the specific cases where they do.

What You'll Learn:

• The ONLY reason to feed grain to horses (it's simpler than you think)
• Which horses should NEVER have grain (insulin dysregulation, PPID, metabolic syndrome)
• How grain feeding can cause laminitis, colic, behavioral issues, and gut dysbiosis
• The "Absolutely Not, No, Maybe, Yes" framework for determining if YOUR horse needs grain
• Safe grain feeding amounts: maximum limits to prevent hindgut damage
• Why cooked grains are essential (except for oats) and which processing methods work best
• Real-world examples from racehorses, yearlings and broodmares

Key Takeaways: Dr. Nerida reveals her ideal maximum of just 0.5kg grain per 100kg body weight (that's only 2.5kg for a 500kg horse!) and explains why performance actually improves when grain is reduced, not increased. She also busts the myth that overweight, lazy horses need more grain - often it's exactly the opposite.

Perfect for horse owners who want evidence-based nutrition advice without the confusion. Whether you're dealing with a good doer, a hard keeper, or a performance horse, this episode gives you the tools to make informed feeding decisions.

Discover the answer to one of the most common questions asked by horse owners worldwide: how much hay does my horse actually need? PhD equine nutritionist Dr. Nerida reveals why this seemingly simple question has life-or-death consequences for your horse's health and performance.

What You'll Learn:

• The deadly consequences of underfeeding hay and how it causes colic, gastric ulcers, and behavioral problems
• That horses evolved to eat 18 hours per day and what happens when we disrupt this
• Dr. Nerida's recommended hay amounts: 2-3% of body weight daily (that's 10-15kg for a 500kg horse)
• The critical 4-hour rule: never let your horse go longer than 4 hours without hay
• How insufficient hay causes psychological stress, leaky gut, and performance issues
• Why hay is a performance horse's "secret weapon" - not just filler

Key Insights: Learn how proper hay feeding prevents gastric ulcers by maintaining saliva production, supports the vital hindgut microbiome, and provides natural muscle buffering through potassium. Dr. Nerida explains why the volatile fatty acids from hay fermentation act like a "fully charged battery" for performance horses, and how proper forage feeding can extend the time to muscle fatigue.

Special Focus on Easy Keepers: Specific advice for overweight horses - don't reduce hay quantity, reduce hay quality instead. Discover how feeding up to 50% straw can help weight loss while maintaining gut health and preventing the behavioral issues that come with hay deprivation.

Practical Solutions: Get specific guidance on using slow-feeding hay nets, measuring hay with luggage scales, and the importance of spreading hay consumption over 24 hours. Plus, learn how the My Happy Horse virtual nutritionist app takes the guesswork out of forage calculations.

Perfect for horse owners who want to understand the science behind forage feeding and avoid the serious health consequences of getting it wrong.

In this evidence-first episode, Prof. Brian Nielsen (Michigan State University) and graduate researcher Renee Harbowy join me to unpack what we really know—and don’t—about glucosamine, chondroitin and MSM. We trace the research history (hello, cell culture studies), talk frankly about why high-quality equine trials are rare, and look at a clever, blinded field study run at an all-girls riding camp with ~80 horses on site.

You’ll hear how horses were screened and balanced into supplement vs placebo groups, what was measured (stride length, flexion tests, IMU-based symmetry), and why lameness naturally fluctuates enough that you can fool yourself into thinking something works when studies are run without a control. We also touch on osteoarthritis prevalence in aging horses—the demand driver behind these products—and a cautionary detour into sheep models that shows why cross-species claims can mislead.

And we finish with a detailed look at what best practice management for joint health actually looks like, including a suggestion to lunge yourself to feel how it feels on your own joints! Such a cool idea! I have to admit this conversation really opened my eyes to what we, as horse owners will be missing if we are relying on joint supplements to protect joints, versus relying on proper nutrition and management.  

If you buy joint supplements, think about your horses joint health a lot, or just want your horse to be healthy and happy for a long lifetime, this conversation is a must!

When used well, strip grazing becomes one of the most effective tools for managing weight, preventing laminitis and protecting pasture. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida walks through exactly how strip grazing works in real life, why it matters and how to tailor it to your climate, pasture growth stage and horse’s body condition.

Drawing on published research, decades of practical experience and her own track-plus-strip system at home, Nerida explains how to move fences strategically, when to increase or decrease allocations, why early-morning moves matter in spring and how straw can be a powerful safety net for easy keepers. She also covers the role of back fencing, how to protect pasture species, and how track systems improve movement, welfare and gut health.

If you manage good doers, laminitis-prone horses or simply want clearer guidance on how much to move the fence and when, this episode gives you the practical framework you need.

Dr. Nerida and Orla are back with another Q&A episode that tackles everything from freaky behaviour on ryegrass and mycotoxin binders to a virtually unknown reason your horse might be completely off its feed, plus, how to tell if your grain is safe to feed.

What You’ll Learn:
• The early signs of ryegrass staggers (and why some horses go totally “goblin mode” 👻)
• Which pasture mycotoxins are most dangerous and how to manage them
• Why mycotoxin binders don’t work the same for all toxins—and when they do work brilliantly
• The truth about cooking grains: does heat destroy nutrients or improve digestibility?
• How to test if your horse’s grain is properly processed (and why faecal pH is your new secret weapon)
• Real-world case studies from broodmares to racehorses, including why fescue can delay foaling
• The surprising fact that some horses seem more resistant to pasture toxicity than others

Dr. Nerida and Orla also cover how starch is packaged up like “golf balls” in raw grain and how heat + moisture busts those open for efficient digestion.

Plus, you’ll learn how the MyHappy.Horse app can help you track your horse’s gut health using real data like faecal pH; practical, evidence-based tools every horse owner should be using.

🎙️ Whether you're managing a quirky pony or fine-tuning a racehorse’s diet, this episode will help you decode behaviour, evaluate risk, and feed with clarity and confidence.

Join Dr. Nerida as she tackles a listener question about feeding “marey mares” — those behaviourally expressive, sensitive, frequently moody, often brilliant mares. This solo Happy Horse Nutrition episode explores why behaviour challenges in mares are rarely caused by specific feed ingredients — and are almost always rooted in gut health, management, or pain.

What You’ll Learn:
• Why hindgut health is THE most important nutrition factor in mare behaviour 🐴
• How the gut-brain axis influences temperament via dopamine and B-vitamin production 🧠
• Why feeding hay before riding is non-negotiable for sensitive mares
• The 3 things all mares need for stable mental health
• How mycotoxin contamination (especially zearalenone in corn 🌽) wreaks hormonal havoc
• Why pain (feet, ovaries, saddle fit) must be ruled out first before blaming the feed
• The right way to test individual ingredients when sensitivities are suspected
• And why your own energy might be mirroring back through your mare’s behaviour 🪞

Dr. Nerida shares how her own anxious horses transformed through life changes, not supplements — and reflects on 25 years in the field, where true ingredient sensitivities are exceedingly rare (just 3 for alfalfa, 1 for soy!).

🎧 Ideal for mare owners navigating grouchiness, grooming drama, or hormonally “hot” behaviour. Get the real framework for fixing it — starting with pain, gut health, and feeding management, not guesswork.

Discover how Ciaron Maher Racing (CMR) is pushing the boundaries in the Australian thoroughbred racing industry and breaking away from traditional nutrition strategies. In this in-depth conversation, PhD equine nutritionist Dr. Nerida sits down with Katrina Anderson (Sports Science Lead) and Josh Kadlec-Cavanagh (Head of Data and Performance) to reveal the data-driven approach that's challenging decades of traditional feeding practices.

The trio discuss:

• Why feeding less grain (but more digestible grain) leads to better racehorse performance
• The critical role of hindgut microbiome health in racing success
• How faecal pH monitoring allows them to fine tune their feeding program
• The connection between gut health and chronic issues like foot soreness and tying-up
• Why the "footy horses" at CMR have virtually disappeared
• The remarkable case of Saint George: how targeted nutrition reversed severe thrush and fungal issues and got him back on the track
• Understanding the performance slump when transitioning to more digestible feeds; and
• The hard reality about gastric ulcers and race day challenges
  

Kat, Josh and Nerida also cover fiber fermentation vs. grain-based energy systems, managing the grain-to-bodyweight ratio for optimal performance, microbiome testing and its practical applications, reducing dependency on supplements and medications like omeprazole and the importance of lucerne hay before morning work.

Join Dr. Nerida as she explores why ingredient variety is absolutely critical for your horse's health. In this episode, which comes complete with Lucky the Goat 🐐anecdotes, Dr Nerida reveals the three reasons diverse diets keep horses healthier, happier, and more resilient - and why feeding just one or two ingredients is putting your horse’s health at risk.

What You'll Learn:

• Why horses chew bark and fences (and what it tells us about their diet)
• The THREE critical benefits of ingredient variety: balanced nutrients, toxin dilution, and microbiome diversity
• How different forages and feed ingredients work together to meet nutrient requirements
• Why nitrate and mycotoxin testing is essential for racing stables and performance horses
• The downsides of monoculture pastures and why horses need species diversity
• Protein combining: how different proteins work together as "Tetris pieces"; and
• Dr. Nerida's personal feeding program for her daughter's OTTB (with multiple forage and fiber sources)

Dr. Nerida reveals that the more ingredients in your horse's diet, the better chance you have of meeting complete nutrient requirements - it's like putting together a puzzle where each ingredient fills specific gaps. She explains how ingredient diversity protects horses from toxins (like nitrate in hay or mycotoxins in moldy feed) by either allowing them to avoid problem forages or diluting toxins to safe levels. And she explains how horses with diverse microbiomes can handle stress events like competition and travel without developing colic or diarrhea, while horses on limited diets are far more vulnerable to dysbiosis.

When a horse presents with ulcers, colic risk, poor performance, slow healing,  unexplained weight change or a plethora of other health conditions, nutrition may be part of the story—even if it isn’t the primary cause.

In this episode, Dr Nerida, PhD shares a practical, vet-friendly framework for a rapid field assessment of diet: the same fast mental checklist nutritionists run through when they first meet a case.

You’ll walk away with three high-impact screening steps: 

(1) is there enough forage (and are there long fasting gaps that increase gut risk), 

(2) is grain being fed appropriately and in a digestible form (to avoid starch overflow into the hindgut); and 

(3) is the horse actually receiving correct supplementation—meaning a fortified feed/balancer/vitamin-mineral supplement at the proper feeding rate to cover common nutrient gaps and prevent “silent” deficiencies.

To kick off Season 2 (2026), we’re re-sharing our most listened-to Season 1 episode of the Happy Horse Nutrition Podcast, and it’s a classic for a reason.

In this practical, science-backed episode, PhD equine nutritionist Dr Nerida breaks down what it really means to feed your horse like a horse, using evolution and gut physiology to help you understand and make modern feeding choices that truly honour your horse’s gastrointestinal physiology.

You’ll learn the 5 non-negotiables:

• Why forage-first is the cornerstone of gut health
• How fibre/forage variety supports microbial diversity (and why that matters for the whole horse)
• Why horses need near-constant access to fibre to help protect the stomach
• Why forage alone won’t cut it and the importance of a balanced diet; and
• The importance of clean water + salt, every day

Whether you’re a horse owner, trainer, or vet, this episode gives you a simple, foundational understanding of every horse’s basic nutrition needs

To wrap up 2025, we’re resharing our most popular guest interview from Season 1 — and it’s a favourite for good reason.

In this episode, microbiology expert Dr Belinda Chapman and Dr Nerida take us inside your horse’s hindgut ecosystem.

Together, they look at what the microbiome actually is, why horses rely on microbes far more than we do, and how the balance between the fibre-loving “good guys” and the weedy, greedy starch-fermenters can influence everything from digestion and energy production to health, performance, and behaviour.

Dr Belinda and Dr Nerida also dive into some seriously fascinating concepts (in a very listenable way), including:

• Why horses have a more complex microbiome than humans
• The underappreciated role of anaerobic fungi in fibre breakdown
• What “quorum sensing” is (and why it’s a bit mind-blowing); and
• Why microbial diversity = resilience (and what that means in the real world)

In this last new episode for 2025, professional equine nutritionist Dr Nerida shares five ingredients she loves using in real-world diets, and five (actually if you listen carefully, she sneaks in 6!) ingredients she tries hard to avoid, including a couple she’d happily see disappear from horse feeds altogether!

Listen as Dr Nerida frames nutrition the way she actually practices it — like a big jigsaw puzzle. No magic ingredient, no perfect feed… just smart puzzle pieces put together in the right way to support horses and to honour the physiology of their ancient gut.

Plus find out which feed ingredient(s) makes it onto the ‘avoid’ list, mainly because of their marketing claims (hello “grain-free” when you’re not actually grain free!). 

This episode is an easy listen, and will help you think clearly about nutrition, read labels better, and make more confident feeding decisions that your horse and their hindgut will thank you for.

Wishing you a happy and safe festive season 🎄❤️

Feeding horses during emergencies (bushfires, floods, storms, evacuations) can quickly become a “take what you can get” situation, but the choices you make in your makeshift feed room can determine whether your horse copes… or tips into dehydration, gastric ulcers, hindgut dysbiosis, colic, or even laminitis. In this practical episode of the Happy Horse Nutrition Podcast, PhD equine nutritionist Dr Nerida shares her approach to natural disaster horse feeding with one core rule: keep the diet as close to normal as possible.

You’ll learn how to prioritise clean water (and what to do when horses won’t drink), why hay and fibre are your horse’s lifeline, and how to reduce risk when you’re forced to swap feeds or hays fast. We cover smart strategies like ingredient/forage variety, feeding little and often when hay is limited, avoiding the trap of over-using grain/hard feed, and why you should keep hay available when pasture regrows. There’s also specific guidance for horses with PPID (Cushing’s), insulin dysregulation, and laminitis, including when soaking hay might help in a tight spot.

If you want a simple emergency checklist to protect hydration and gut health when your horse’s world is upside down, this one’s for you.

Forage sits at the very heart of equine nutrition, yet for most horse owners, the numbers on a hay or pasture analysis can feel like a foreign language. In this deep-dive episode of the Happy Horse Nutrition Podcast, Dr Nerida sits down with Anthony Balzer and Kimberly Detmers from Feed Central and Local Ag for an enlightening conversation about what’s really in our forage, how much it changes, and why testing matters more than most people realise.

Together, they explore how hay and pasture analysis can influence everything from basic health to performance, soundness, growth, and healthy pregnancies. You’ll hear:

• Why forage can make or break a horse’s health—and sometimes an entire racing stable
• How hay and pasture testing actually works
• The critical mineral shifts that dictate whether a youngster grows sound joints or ends up with OCD
• Why nitrate levels matter (and the way it affects laminitis, broodmare health, and athletic performance)
• What “safe” NSC levels look like for laminitic horses
• Why TEFF hay is not always the low-sugar safe option many believe
• How ingredient and species diversity in forage protects gut health and reduces colic risk
• How to dilute risk by feeding multiple, tested forages
• What makes a “near perfect” performance horse hay—and why no single hay is perfect for every horse; and
• Where to send hay and pasture for analysis in Australia or overseas

With practical examples, on-farm stories, and clear explanations, this episode makes hay and pasture numbers approachable for every horse owner—from broodmare managers to everyday riders.

If you’ve ever wondered what your hay and pasture is really doing inside your horse, this episode is essential listening. Understanding forage is one of the most powerful ways to keep your horses healthy, performing well, and protected from avoidable nutrition-related issues.

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida tackles a pasture risk that catches many good horse owners out: high-oxalate warm-season grasses that can block calcium absorption, slowly weaken bone, and set horses up for nutritional secondary hyperparathyroidism (Bighead disease). 

You’ll learn the simple physiology behind it (the “bone calcium bank” concept), why blood calcium can look normal even when bones are being depleted, and the real-world signs that are easy to misread; shifting lameness, sore or grumpy behaviour, odd gait, skull changes, loud breathing noise under work, dental issues and poor hoof quality. 

Nerida walks you through practical pasture ID tips for the big culprits—kikuyu, buffel, couch/bermudagrass, and the high-risk one: setaria! And explains how oxalate levels and risk change with growth stage and location (including cooler regions in summer). 

Finally, she outlines prevention: targeting a calcium: oxalate ratio of at least 0.5:1, keeping calcium balanced with phosphorus and magnesium, why lucerne/alfalfa helps on multiple fronts, and when it’s smarter to use a properly formulated balancer or get expert help… especially if setaria is involved.

Track systems (perimeter grazing systems) can look deceptively simple… but when they’re designed well, they deliver things horses are wired for: friends, freedom, and forage… with extra movement built in.

In this episode, Dr Nerida is joined by the wonderful Dr Katherine Goldberg (DVM, LCSW), a veterinarian and clinical social worker,  to unpack what “species-appropriate husbandry” actually means in the real world, and why track systems aren’t just a “weight loss tool” for good doers, but a way we can help horses to live in a way that truly honours their needs. 

Dr Nerida and Dr Katherine talk about the concept of horses being behaviourally starving even when obese, the two welfare rules Katherine won’t budge on, and how meeting these basic needs changes behaviour, safety, gut health, and the horse–human relationship.

You’ll also get practical, immediately usable setup guidance on track width, why varying widths can create natural movement patterns, and how separating resources (water, hay, shelter) encourages that nomadic, forage-and-walk lifestyle horses evolved for. 

Dr Katherine is the most beautiful human, driven by the desire to help us all create better, happier, more species-appropriate lives for our equine friends in which our horse-human relationships and horse goals, whatever they may be, can flourish! If you’d like to get in contact with Dr Katherine, you can find her at horsesfirststewardship@gmail.com

Free faecal water (also called free fecal liquid) is one of those horse problems that looks “not that bad” on paper… but how 'bad' is it? 🐴💦

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida unpacks potential reasons why FFW is suddenly being talked about everywhere, from first hearing it at a conference in Dijon (2016) to seeing it dominate conversations at AAEP Denver (2025). And yes… she asks the uncomfortable question: is this another disease of modern management impacting an ancient gut?

You’ll learn:

• What FFW is 
• Why it’s likely multifactorial (forage changes, fibre variety, grain load & digestibility, sand irritation, ulcers, nitrates…)
• The practical “low-hanging fruit” steps to try first, in a logical order to help resolve FFW
• Why microbiome research can be misleading when it’s only measured at broad levels (and why species-level testing may be the next big breakthrough); and
• When to loop in your vet (sand assessment, ulcer scoping, more advanced options like faecal transplant)

If you’re dealing with FFW, this is your calm, evidence-informed roadmap to helping your horse.

As always, please follow the podcast so more horse owners can find this, and if it helped, share it with a friend (or your whole agistment chat 😉). 💛

What happens when your horses live on mostly straw for 10 days… and one of them decides to protest with full-blown diarrhoea? 😅 In this Q&A-style catch-up, Dr Nerida and Orla unpack a very relatable “whoops” moment and use it to teach one of the most overlooked fundamentals in horse gut health: fibre diversity.

They break down why straw is a very different beast to hay (hello, lignin), why some horses cope while others fall apart, and why “just add a product” isn’t always the smartest first move. From there, the conversation goes behind the scenes of the feed industry, mixed-species feed mills, the very real risk of ionophore contamination, and how to ask the right questions of manufacturers. Then it gets nerdy (in the best way) with least-cost vs set recipes, why crude protein can be misleading, and the lysine + leucine muscle-building “bricklayer and bricks” analogy you’ll love.

In this episode you’ll learn:

• Why restricting forage to one source can trigger loose manure/free faecal water in some horses
• Why gut “fixes in 3 hours” are usually not how physiology works (and when electrolytes can confuse the picture)
• How to read a feed label to spot vague “least-cost” ingredient wording
• Why protein quality matters (especially for young horses, broodmares, and performance horses)

Feeding an Off The Track (OTT) in the first 12 months can be a worry inducing juggle… appetite, behaviour, ulcers and those classic “why won’t you hold weight?” situations. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida shares her practical approach to feeding OTTs in their first year off the track so they can settle, digest fibre properly, and become easier to keep long-term.

Nerida explains why many OTTs arrive with gut health issues. Racing routines and high-energy feeds can increase gastric ulcer occurence and shift the hindgut microbiome away from the good fibre-fermenting microbes. And when the gut isn’t right, it often shows up as a fussy appetite, tricky behaviour, and slow weight gain in OTTs. The episode breaks the first year into two phases: months 1–6 focus on gut rehab with forage first, fibre diversity and balancing vitamins and minerals the focus; then months 6–12 shift to weight and muscle development, with one big caution… weight gain diets change behaviour, sometimes dramatically.

Listen to discover how to feed your OTT in the first 12 months off the track for brilliant results… setting your OTT up for a lifetime of health, happiness, calm behaviour and brilliant performance.

NSC is one of those three-letter acronyms that pops up on feed bags and hay reports… and consistently manages to confuse even the most dedicated horse owners. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida McGilchrist unpacks Non-Structural Carbohydrates (NSC) in a practical, horse-owner-friendly way.

This episode looks at what NSC actually is (starch + water soluble carbohydrates; WSC), how it relates to WSC, whether we should be using WSC or ESC to calculate NSC (see, it gets confusing!), and why that 'fructan piece' matters for both laminitis risk and the hindgut microbiome.

You’ll learn why NSC is everywhere in hay, pasture and feeds, and why it’s levels can fluctuate so dramatically, depending on plant type, time of day, climate, temperature, drought stress, and even soil fertility. 

Nerida shares real-world examples (including from her own horses) to explain what happens when NSC is too high. Problems can include crazy high insulin levels, laminitis, colic, tooth decay and microbial dysbiosis. And she explores why “not enough NSC” can also be a problem in performance horses where energy intake, palatability, and gut function matter.

If you’re feeding a pony with insulin dysregulation, a horse with PPID/Cushing’s, a laminitis-prone horse, or a metabolically healthy high performance athlete, this episode will help you make informed, smarter decisions around NSC.

A horse that won’t eat isn’t being “fussy”… it’s a red flag. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida, PhD equine nutritionist and founder of the MyHappy.Horse app, breaks down the most common nutrition-related reasons horses go off their feed, what they look like in real life, and what actually helps.

Nerida covers hindgut disturbance (including hindgut acidosis) and the appetite knock-on effects, including the destruction of  vitamin B1, why some horses go off grain but still eat hay, and how faecal/manure pH can be a handy monitoring tool (with the key low-pH threshold to watch).

You’ll also hear how gastric ulcers can affect appetite (and why it’s not always obvious), plus the salt trap: too much salt can make feeds unpalatable (and may worsen discomfort in ulcer-prone horses), while too little sodium, especially after watery diarrhoea or heavy sweating, can switch appetite off entirely.

And don’t miss the quick but important one: DON mycotoxin (“vomitoxin”). If a new batch of feed is eaten for a few days, then suddenly refused, it may be the feed, not your horse, and testing can help confirm it.

You’ll also hear the story of Breeze, Nerida’s very old mare, and the tiny, cheap change that brought her appetite back and genuinely saved her life.

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida is joined by Joanna Lepiarczyk from Horses Explained for a fascinating and deeply important conversation about horse mental health, equine behaviour, and the role that nutrition and feeding systems play in shaping a horse’s emotional wellbeing.

We explore why behaviour is so often a form of communication, why a quiet compliant horse is not always a happy horse, and how chronic stress can affect a horse far more profoundly than many owners realise. Joanna shares her perspective on horse depression, the emotional cost of restricted forage and limited choice, and why the foundations of a good horse life are surprisingly simple: forage, freedom, and friends.

We also talk about the importance of constant access to something to chew, forage variety, movement, predictability, agency, and why these are not “nice extras” but core building blocks for a horse’s physical, mental, and emotional wellbeing.

This is a thoughtful, compassionate, and at times confronting conversation that will encourage you to look beyond behaviour and think more deeply about how your horse is actually experiencing daily life.

If you care about horse welfare, equine mental and emotional health, feeding management, and giving horses the conditions they need to truly thrive, this is an episode you won’t want to miss. 🐴

Grains are one of those ingredients that get demonised in the horse world… or are fed completely on autopilot. And neither is an ideal situation.

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida digs deep into her PhD research and explains why grain itself isn’t bad — it’s more like a power tool. Used well, in the right horse, grains are incredibly useful. Used carelessly (wrong type, wrong form, wrong amount), and grains can rapidly destroy hindgut health… and in severe cases, even cause death.

In this episode, you’ll learn:

• Why the real issue is starch, and why starch must be digested in the small intestine (and not dumped into the hindgut)
• How uncooked/poorly processed grains can drive hindgut acidosis, microbial dysbiosis, leaky gut, inflammation, behaviour changes, colic and laminitis risk
• Why cracking, grinding, and soaking don’t solve the core problem 
• What “cooked grain” actually means and why extrusion tends to win on digestibility
• Where oats fit and why uncooked corn/maize is a hard no!
• Which horses should avoid grain altogether (including insulin dysregulation/PPID/EMS, PSSM/tying up) vs when grain is genuinely helpful (including thoroughbred racehorses, high-performance athletes)

Grans are incredibly useful ingredients IF you know how to safely feed them. This episode helps you understand why grains are often unsafe AND how to make them safe to feed in appropriate situations.

Is your horse an “air fern” who seems to gain weight just by looking at grass?

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida walks you through how to feed overweight horses and good doers for safe, sustainable weight loss, without leaving them hungry, stressed, nutritionally deficient or at higher risk of problems like gastric ulcers.

Weight loss for good doers is not as simple as “feed less”. In fact, restricting forage too harshly will create serious gut health, welfare and behaviour problems. Instead, Nerida explains how to reduce calorie intake while still keeping your horse chewing, happy and with all of their nutrient requirements met.

You’ll learn the five key steps to feeding horses for weight loss, including remove high-energy feeds, manage access to pasture and high quality hay, use low-calorie forages like mature grass hay and straw, balance vitamins and minerals correctly, and how exercise and winter can make such a difference.

This episode also covers practical tools for managing laminitis-prone , insulin-dysregulated , cresty-necked and easy keeper horses, including use of forage testing, slow feeders, track systems, controlled grazing and the importance of measuring body condition, body weight and cresty neck score over time.

If you have agood doer or an overweight horse that needs to lose weight safely, this episode will help you understand how to create a weight loss diet that protects gut health, supports the hindgut microbiome and keeps your horse (and you!) as happy as possible.

Is your horse underweight, a classic hard keeper, or one of those horses who seems to need a ridiculous amount of feed just to hold condition? In this episode of the Happy Horse Nutrition Podcast, Dr Nerida takes a practical, gut-first look at feeding horses for safe, effective and sustainable weight gain.

Because weight gain is not simply a matter of “just feed more”. Yes, a horse needs to eat more energy than they use in order to gain weight, but they also need to be able to digest and use that energy. And that is where so many weight gain diets go wrong. If the cause of weight loss has not been identified, the hindgut is struggling, the diet is unbalanced, or the horse is being pushed too hard with high-starch feeds, owners can end up feeding more and more, while the horse still fails to thrive.

In this episode, Nerida walks through the five key steps to feeding for weight gain, starting with identifying why the horse is underweight in the first place. From there, she explains why the hindgut must become a fibre-fermenting powerhouse, why forage variety and fibre diversity matter, how to balance the diet properly, why high-quality protein is essential for building muscle and topline, and how to add high-energy ingredients like super fibres, oils and well-cooked grains safely.

Nerida also talks about something every owner needs to understand before starting a weight gain diet: higher-energy diets can affect behaviour. The aim is not to create a fire-breathing dragon under saddle. The aim is to build a healthier horse who can gain condition, support muscle development, maintain better gut health and eventually hold weight without relying on huge amounts of supplementary feed forever.

Is canola oil really as bad as people say… or has it simply been one of the most unfairly demonised ingredients in horse nutrition?

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida is joined by Orla for a fascinating and surprisingly fun deep dive into the real story behind canola oil. They unpack where the wild claims came from, including the viral email that helped fuel decades of fear, and separate old rapeseed oil facts from modern canola oil fiction.

Dr Nerida and Orla talk about erucic acid, GMO confusion, the strange myths linking canola to everything from blindness to mad cow disease, and why scary misinformation can stick so powerfully in people’s minds. They also bring it back to what really matters for horse owners: where canola oil fits in equine diets, how its omega-3 and omega-6 profile compares with other oils, and why it can actually be a very useful and appropriate choice in the right situation.

If you have ever wondered whether canola oil is truly harmful, or whether this is another nutrition myth that has taken on a life of its own, this episode is for you.

Here is the full, crazy backstory canola oil email in case you’d like to read it: https://www.snopes.com/fact-check/canola-oil/

Orla is back in the Q&A seat… and she’s come armed 😅 In this episode of the Happy Horse Nutrition Podcast, Orla has curated a stack of listener questions (and kept Dr Nerida completely in the dark), so it’s a fast-paced, practical chat that bounces from industry ethics to real-life feeding decisions you’ll recognise instantly.

We start with a big one: what actually makes someone a “nutritionist” in the horse world, and why that label can be meaningful… or totally meaningless. Nerida unpacks the difference between qualifications, experience, and the uncomfortable reality of “armchair experts” giving confident advice that can cost horses their health.

From there, the conversation gets wonderfully hearty:

• Raw/cracked grains (especially corn): why this can be a hindgut wrecking ball when fed inappropriately, and what “gold standard” feeding looks like when welfare and performance matter.
• Hair analysis: when it might be useful (think toxins/heavy metals), why it often isn’t reliable for everyday nutrition decisions, and why diet analysis beats guessing, every time.
• Metabolic ponies + ulcers: why so many EMS “good doers” end up with serious gastric ulcers, and the management patterns that quietly set them up to fail (hello, long hours without forage).
• Orphan foals: Nerida shares a practical, “doable in the real world” approach to feeding orphan foals, including a simple milk-mixing recipe and how frequency of feeds can make or break a foal’s gut.

If you’ve ever felt overwhelmed by conflicting advice, marketing masquerading as science, or you just want a clearer path to feeding with confidence—this one’s for you. 🐴💛
