How Does Energy Flow Make Your Horse Alive And Healthy? The Horse's Advocate Podcast #183
1w ago00:25:51Tap to summarizeEverything that happens in horses requires energy. Similarly, every household and business has a budget. When there is enough money, everything is good, and with our horses, if there is enough energy, the horses remain healthy and even thrive. This podcast looks at energy flow like a budget: there is a supply of energy, and there is demand for it to keep the horse functioning. At a cell level, every cell has a function that requires energy: muscles contracting or the brain thinking. In addition, cells also have an energy budget for growth, maintenance, and repair. Finally, the products of metabolism (reactive oxygen species, or ROS) need to be removed, which also incurs a cost. Any added "resistance" to the flow of energy in the cell, such as inflammation and stress, reduces the available energy for the cell's function and maintenance. Timestamps: 0:00 - The basic cause of health in horses. 1:09 - The flow of energy. 4:30 - Oxygen is required for life. 5:36 - Moving one electron from a hydrogen atom to an oxygen atom creates energy that the cell uses. 7:20 - Life is the flow of electrons from hydrogen to oxygen. 8:14 - The vital function of cells. 9:14 - All cell functions have an energy cost, and all cells have an energy budget. 10:30 The cell's vital purpose is determined by its resistance to the flow of energy through the cell. 12:39 - The "sweet spot" of energy flow and energy resistance. 13:16 - The three parts of cell function: vital purpose, growth/maintenance/repair, and stress 17:03 - How can energy flow and resistance in horse cells be changed? 19:37 - Summary: The supply and demand for energy determine the cell's energy potential. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973, earning his Doctor of Veterinary Medicine from Cornell University in 1984.

Transcribe →How Helpful Are Vitamins and Supplements For Our Horses? - The Horse's Advocate Podcast #182
2w ago00:46:16Tap to summarizeThere are two ways to provide vitamins, minerals, and amino acids to your horse: through factories or nature. In this episode, I discuss how horses obtain these nutrients naturally and where natural sources fall short. I also explore the production of these nutrients in laboratories and factories. I spend some time looking at where using man-made materials is required due to the environments in which horses live. For example, horses grazing large fields of fresh green grass undoubtedly have different needs than those raised in a dry lot. You will be surprised how adaptive horses can be up to a point. What may be more surprising is how few companies make the ingredients we discuss. Of concern are the many hands in the supply chain, in the production of the final product, and how often they sell the same ingredient under different brand names. 0:01 - Why horses may need supplements. 01:49 - Water: ground versus distilled. 02:17 - Minerals: macro and micro. Common deficiencies. Chelation. Why horses rarely get mineral deficiencies. Thumps (Synchronous Diaphragmatic Flutter), Electrolytes, Rickets, Magnesium deficiency and its associated behavior changes. 09:02 - Protein and amino acid deficiency: Natural versus synthetic amino acids, Signs of an amino acid deficiency, Genetic modification of microorganisms. 13:29 - About 80% of all amino acids and vitamins are made in China—discussion of the supply chain from raw materials to production facilities. 17:15 - The first of two problems: Man-made vitamins and amino acids are either made from chemicals or from genetically modified microorganisms, and the long supply chain from raw materials to the final product in your barn has too many points of non-verifiable steps and materials. 18:32- The second of two problems: How can the deficit or the results of supplementation be verified in the horse? 21:37 - Testing the diet that the horse is eating and comparing that to the signs of deficiencies. 23:21 - The fallacy that placing supplements in the food, other than macronutrients, will fix an underlying energy problem (mitochondria). 25:17 - The chemical in gunpowder that caused increased mitochondrial function and subsequent loss of body fat despite over-eating. It was called DNP (dinitrophenol), which acts as a mitochondrial uncoupler: It disrupts the proton gradient in cells, causing the body to "waste" energy as heat (thermogenesis) instead of storing it as ATP. This ramps up metabolic rate (sometimes by 30–50% or more), leading to rapid fat and carbohydrate breakdown and significant weight loss—even without dieting. (Wikipedia) Banned in 1938 by the FDA. 26:45 - Without the ability to test horses for a deficiency, feed companies just throw in amino acids, vitamins, and minerals to cover any possibilities without any proof they are needed. 29:30 - Vitamin C in humans and horses. 31:06 - Vitamins A, D, E, and K in horses. 33:51 - The B Vitamins. 34:35 - Summary of how and where raw materials are made, and the long supply chain to the final product sold to horse owners. Look at the horse for a deficiency. Look at the diet for deficiencies. Protein deficiency is the most common one seen, with the most problems in horses due to the lack of protein. Remove ingredients that inflame the gut. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.

Transcribe →Marketing and the Funding Of Science - Reasons Why Horses Are More Sick, Not Less - #181 The Horse's Advocate Podcast
3w ago00:44:30Tap to summarizeMy mailbox and inbox get a never-ending stream of advertisements, all promising that my horse will become free of disease or super-athletic. Some boast scientific research backing their claims, while others have endorsements from winning contestants. All use the time-tested formula of identifying a condition your horse might have, then claiming their product will resolve it. But is any of it true? I will review some advertisements sent to my mailbox and guide you through the essential questions to help you objectively evaluate their claims. My main goal is to encourage you to make informed decisions and consider whether prevention is often more effective than seeking costly cures. Science may be undergoing a revolution because the results scientists are producing don't correspond to improvements in human healthspan or lifespan; both are becoming stagnant. I go over some of the changes at the human level and show how they will help our horses if adopted there as well. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.

Transcribe →What Can Horse Owners Do To Prevent The Top 3 Foal Complications? - #180 The Horse's Advocate Podcast
4w ago00:35:46Tap to summarizeFoals are especially vulnerable in their first months of life. Think about the first time you met a newborn foal—did you know it takes both knowledge and experience to protect them well? In this podcast, we'll dive into three of the top challenges horse owners face with foals just after birth to a few months old. This isn't a complete list, so remember, teaming up with a seasoned professional will always help you stay ahead of problems. I picked these three foal problems because they're common—and, good news, they're all preventable! Imagine welcoming a new foal into the world. Suddenly, you learn that one of the biggest risks it faces is failure of passive transfer (FPT). This can happen if the foal does not drink the mare's first milk within 24 hours of birth. Or, it may occur if the mare's milk leaks out before birth. The resulting weak immune system leaves your foal vulnerable to everyday germs. Illness and even death can follow. Have you ever noticed a foal with diarrhea? It's a common issue, with several possible causes. Diet is usually to blame, but sometimes more serious issues are at play. Have you ever noticed a foal struggling to walk, or perhaps heard about issues like contracted tendons, angular limb deformities, or epiphysitis? In addition to infection and digestive concerns, these developmental orthopedic diseases (DOD) are conditions I often see when I'm called to work on the mare's teeth. The good news is that these issues are almost always diet-related and preventable. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.

Transcribe →The Reason Why Horse Teeth Need To Be Filed (Floated) - #179 The Horse's Advocate Podcast
Jun 2200:39:13Tap to summarizeFiling off sharp edges inside a horse's mouth may seem a bit odd at first glance. If nature is perfect, you might wonder, why would horse teeth need this help? How did horses get by without floating, the process that smooths those sharp edges? These are thoughtful questions, and I explore them—and more—in this podcast. Some of the ideas I present are: - It is the threshold of pain, not how sharp the edges are, that determines how often to float. -Not all tooth enamel is the same among horses. -If a horse is chewing, their teeth need doing. -Using a bit moves the soft tissue into the sharp edges. -Waiting until a problem occurs often results in more aggressive treatments and a poorer outcome.
Transcribe →Can Ertugliflozin Save My Horse? - #178 The Horse's Advocate Podcast
Jun 1500:18:39Tap to summarizeGlucose is an essential sugar for horses, but too much of it can be harmful. While diet is your main tool for reducing glucose intake, what can you do when your horse still struggles with glucose and insulin control? And are there medications that can help lower blood glucose? Let's explore one option together. If dietary changes are not enough, other strategies can help manage high glucose and insulin. For instance, veterinarians are now turning to a human drug called ertugliflozin (er-TUG-li-flo-zen) to lower blood glucose with promising results. In this discussion, you'll discover how this drug and others in its class work, what the treatment plan entails, and possible side effects to monitor. I'll also explore the cost of treatment and discuss current research on its use in horses.
Transcribe →Glucose - The Mystery Of This Required Sugar - # 177 The Horse's Advocate Podcast
Jun 800:35:08Tap to summarizeGlucose is one of many sugars. It is an essential nutrient for both horses and people. When talking about sugar in food, you might hear words like carbs, starch, fructose, lactose, saccharide, or others. But for now, let's just focus on glucose. Without it, our horses—and we—cannot survive. Yet glucose damages everything it touches inside the body! It is so harmful that the phrase "glucose disposal" is often used to describe how the body protects itself from glucose. Insulin helps the body remove glucose. Without insulin, glucose levels rise in the bloodstream, harming whatever they come into contact with. To control blood glucose levels, cells respond to insulin. When a cell takes in as much glucose as it can, it stops responding to insulin. This is normal and needed for the complex process to work. If insulin resistance happens every day, why is it a problem when your horse has it? That's what this podcast is about. I'll explain how the body uses glucose, how it protects itself, and when insulin resistance becomes a real issue.
Transcribe →Am I Too Old To Teach The Young Horse Owner? #176 The Horse's Advocate Podcast
Jun 100:18:51Tap to summarizeNew horse owners join the community every day, from children to adults with little or no experience. Many expect horse ownership to be as simple as using everyday conveniences like microwaves or making phone calls. Yet, horses are fundamentally different. Unlike technology, which responds reliably to our commands, horses have evolved to interpret and respond to their environment using all their senses. This makes horse ownership far more complex than people often assume. To address this complexity, many new owners seek additional education or guidance to better understand their horses. But if the teaching material comes from other inexperienced people, the instructions the new owners find are either too complex, with a "to-do list" too long to remember, or are based on specialized equipment they have to purchase. The solution lies in learning how we are perceived by the horse and how we can change ourselves to help the horse understand us. To do this, horse owners need to find a mentor, observe how the horse responds to them, and then work on changing themselves so the horse perceives them positively. Stand in front of a mirror to find the solution in yourself, rather than looking at the horse to change.
Transcribe →Common Plant and Tree Toxins of Horses in North America - #175 The Horse's Advocate Podcast
May 2700:21:21Tap to summarizeHorses graze on grass and plants, not trees, because their digestive tracts—shared by equids, tapirs, and rhinoceroses—cannot digest wood. Unlike ruminants (cattle, deer, goats), they avoid lignin. When starving, however, horses may eat almost anything, which is why some plants and trees become toxic. The goal of this podcast is not to make you plant and tree experts, but to help you appreciate two key principles of horse care: always provide adequate protein and forage, and proactively remove any potentially harmful vegetation before curious horses can reach it. Your horse's health depends on your attention to these crucial details. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.

Transcribe →Why Science Isn't Helping Horses - #174 The Horse's Advocate Podcast
May 2000:45:55Tap to summarizeScience relies on asking questions, testing them, obtaining answers, and questioning those answers again. Scientists never settle; their curiosity drives them to consider all possibilities, regardless of prior beliefs. There is never a final answer—only answers that are close. This approach depends on continuous inquiry and skepticism. Horse owners are not scientists, and they are not trained to perform "research." Instead, they, and in fact the scientists themselves, are people who have evolved to work towards "social acceptance" as a means to survive harsh conditions that existed for millions of years. Believing other people who appeared to know things you didn't know is a natural phenomenon - people don't want to "rock the boat." The result is the formation of a social identity that gives us stability within a group. Examples include people in horse sports such as reining, dressage, eventing, or racing. Other examples are in differing opinions about treatments or care. This podcast discusses how scientific studies have rules to prevent bias, steering researchers towards a more accurate answer to their question (hypothesis). Unfortunately, untrained people are unable to see when scientific rules are broken, making the results of studies, especially nutritional studies about horses, unreliable when reported by the press. Worse is when those magazines are funded by advertisements that support the outcomes they promote. Hopefully, through this podcast, horse owners will become aware and keep asking questions until the foundational truths about our horses' health are discovered. ******************************* #horses #veterinary #horseteeth #horsecare #equinedentistry Join us at The Horses Advocate Community page: https://community.thehorsesadvocate.com/yt Dentistry: https://theequinepractice.com/ Horsemanship Dentistry School: https://www.horsemanshipdentistryschool.com/c/information/ Facebook: https://www.facebook.com/TheHorsesAdvocate Instagram: https://www.instagram.com/horsesadvocate/ Geoff Tucker is a veterinarian and horseman who has worked with horses since 1973.
