Happy Horse Nutrition

What really happens inside an off-the-track’s gut when you take away the racing diet and start to rebuild the horse from the hindgut up? In this episode of the Happy Horse Nutrition Podcast, Dr Nerida is joined again by Dr Belinda to talk all about Allay, Nerida’s daughter's beautiful off-the-track Thoroughbred mare, and what happened inside her gut as she transitioned from racehorse life into lif...

How much does broodmare nutrition really matter? In this episode, Dr Nerida is joined again by Jess, an equine science student from Charles Sturt University, for a practical Q&A on feeding pregnant (and lactating) broodmares. They unpack the idea of “feeding for two”, and why pregnant mares do not need large amounts of extra energy and protein from day one, but absolutely do need a balanced di...

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 a...

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 mo...

Do calming supplements for horses actually work? Or are we sometimes asking them to do a job they were never going to be able to do? In this episode, Dr Nerida takes a practical, science-based look at horse behaviour, diet and calming supplements. Before diving into ingredients like magnesium, vitamin B1 and tryptophan, Nerida starts with the bigger question every horse owner should ask first: Why...

What do you feed a horse that can’t chew properly? In this episode, Dr Nerida McGilchrist is joined by Jess, an equine science student from Charles Sturt University, for a practical Q&A on dental issues in horses and how they affect nutrition. Using Jess’s own horse as a real-life example, they explore how to feed horses with unusual or compromised teeth, why forage still matters, when soaked...

What happens when a thoroughbred breeding farm reduces grain, increases forage diversity, and prepares yearlings with gut health in mind? In this episode, Dr Nerida is joined by Zac Harris, a thoroughbred breeding farm manager preparing yearlings for sale, to talk about a very different approach to traditional yearling prep. For years, many sales yearlings have been fed high-grain diets, often wit...

Winter can be one of the biggest challenges when feeding horses. So in this episode, Dr Nerida talks all things winter feeding. You’ll learn why preparation matters, that forage is your horse’s internal heater and why body condition scoring with your hands is so important during the colder months. Nerida also covers winter weight loss, feeding good doers, choosing forage quality, fibre diversity f...

We talk a lot about protein in horse nutrition, especially for topline, growth, milk production and gut health, but the number on the feed bag is only the starting point. Two feeds can both say 16% protein on the bag, but they may not support your horse’s body in the same way. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida explains protein quality in horses and why the crude prote...

If you are spending money on joint supplements for your horse, or wondering whether that corticosteroid injection is really helping, this episode is essential listening. Dr. Nerida is joined by Renee Harbowy and Dr. Brian Nielsen from Michigan State University, two of the leading researchers in equine joint and bone health, for an honest, science-based conversation about what actually keeps horses...

There is no time in horse nutrition where you need both art AND science more than when you are feeding a weanling. These funny, curious, chaotic little creatures are walking a tightrope every single day... growing fast enough to reach their genetic potential, but not so fast that they end up with bone or joint disease. Get it wrong, and you are looking at OCD, contracted tendons, physitis, stunted...

In this replay episode, we are bringing back Dr Nerida’s chat with Professor Brian Nielsen on bone health in horses, because the ideas in this conversation have huge implications for soundness, durability, performance and long-term welfare. If you have ever been told that long, slow work builds strong bone, or that the safest path is always to wait until horses are skeletally mature before exposin...

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...

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 “nutrit...

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 i...

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 t...

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 me...

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...

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...

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. Ner...

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...

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 a...

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 ca...

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 D...

Should you feed before you ride? After? Or let your horse graze along the trail? 🐴 In this myth-busting Q&A, Dr Nerida and Orla tackle some feeding folklore that just won’t die. Learn why lucerne before exercise protects the stomach from acid splash, why water restriction after work is probably just a Black Beauty hangover, and how letting horses snack mid-ride actually supports gut health. P...
