Horse Manure Management

Horse Manure Management

Apr 8, 2024 | Compost, Manure

Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Howdy, fellow field friends! Whinny the clinic mouse here, back with another barnyard bulletin. Today’s topic? That ubiquitous pile in the paddock – horse manure! Now, I know what you’re thinking: Whinny, why on earth would you want to talk about… that? Well, my curious readers, horse manure is more than just a smelly mound. It’s a goldmine for both you and, surprisingly, the environment! But managing it effectively can be a real head-scratcher. So, let’s burrow in and learn all about the best ways to handle this… ahem… rich resource.

First things first, why is manure management so important? Imagine a world where all that lovely poop just sits there, piling higher and higher. Yuck! Not only would it be a real eyesore (and a nose-wrinkler!), but it could also create a breeding ground for nasty flies and parasites. Additionally, if not dealt with properly, manure runoff can pollute nearby waterways. Yikes! That’s why responsible horse owners have a plan for their “green gold.”

There are several ways to tackle this task, each with its own set of pros and cons. Let’s explore some of the most common methods:

Method #1: Spreading the Wealth

This might sound strange, but fresh manure can actually be a fantastic fertilizer! Packed with nutrients like nitrogen, phosphorus, and potassium, it can work wonders on pastures and gardens. However, there’s a catch (besides the, well, catch). Fresh manure can be too strong for plants and burn their delicate roots. So, the key here is to compost the manure first. Talk to your hay producer before using it for gardens. Some hay types are sprayed with herbicides which can damage garden plants even after being eaten, digested, and composted!

Springhill Equine Veterinary Clinic

Think of composting as a magical transformation. By piling up the manure with other organic materials like old hay, leaves, and kitchen scraps, and keeping it moist and aerated (turning it regularly is key!), you create a warm, happy environment for tiny decomposer bacteria and fungi to work their magic. Over time, these little critters break down the manure, creating a rich, nutrient-dense soil amendment that’s much gentler on plants. Plus, the heat generated during composting kills weed seeds and nasty parasites, making it a win-win! And if you use fly predators to help manage the flies, you know exactly where to place them: near that compost pile.

Composting does require the most work, but yields the best results over time. There are many ways to manage piles including leaving them alone for prolonged periods and aeration using bounce house blowers. It does require lots of space for those piles, and the fresh edges can be a breeding ground for flies. 

Method #2: Manure Magic with Machines

Now, let’s face it, composting takes time and effort. For some horse farms with a lot of… output… there might be a different solution: manure spreaders. These nifty machines attach to tractors or other equipment and allow for quick and efficient distribution of manure across fields. But remember, even with spreaders, it’s important to follow proper application rates based on soil tests to avoid nutrient overload. An added benefit is that manure dries out quickly when spread making it unsuitable for fly larvae to grow.

Springhill Equine Veterinary Clinic

One downside to the scoop and spread method is that it takes a lot to break down shavings. If you are spreading shavings, they pull a lot of nitrogen out of your soil while they’re decomposing, and that’s not good for your pastures. Another potential problem is that seeds that were in your horse’s hay are now being spread on your pastures, and you can end up planting a lot of unplanned things, depending on what all was in your hay besides hay.

Method #3: Calling in the Cavalry (or Should We Say, the Manure Hauler?)

Maybe your farm doesn’t have the space for composting, or perhaps you lack the equipment for spreading. No worries! Many areas have professional manure removal services. These folks come in with their trucks and trailers and whisk all that manure away.

Springhill Equine Veterinary Clinic

It’s a convenient option, but keep in mind it can be the most expensive route. Much like composting, it also provides an ideal location to concentrate fly management strategies like fly predators and traps. The flies are attracted to the ideal location to eat and breed.

Bonus Tip: Location, Location, Location!

No matter which method you choose, remember that location is crucial. Manure piles shouldn’t be placed near wells, streams, ditches, or other water sources. This helps prevent potential contamination. Additionally, avoid spreading manure on frozen ground (not much worry in Florida) or during heavy rain (always a worry in Florida) – all that goodness will simply wash away and pollute waterways. 

The location should also balance being far enough away from the horses to keep the flies away, while also being close enough to get to conveniently. The single location makes that fly management much easier! Concentrating your efforts at the pile with things like fly predators, traps, and a black tarp over the pile to heat things up can really put a dent in those very annoying stable and house flies!

The Takeaway: Manure = More Than Just a Mess!

So, there you have it, folks! Horse manure management might not be the most glamorous topic, but it’s a vital part of responsible horse care and environmental protection. By utilizing these methods, horse owners can transform what some might see as a waste product into a valuable resource. Remember, a little planning goes a long way in keeping our barnyards (and our planet) healthy!

And hey, who knows? Maybe with proper management, that big, smelly pile could one day turn into a bed of beautiful flowers or a thriving vegetable patch. Now that’s something to think about next time you scamper past the paddock! 

Until next time, stay curious, my fellow field friends!

Joint infections in Horses

Joint infections in Horses

Apr 1, 2024 | Joint Infections

Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Hi everyone, it’s Whinny, the Springhill Equine clinic mouse! Have you noticed that when my docs and techs do a sterile scrub on your horse’s joint prior to an injection, it feels like 5 hours of scrubbing for about 15 seconds of actual injection? And have you noticed that my docs get a lot more uptight about a half inch wound over your horse’s hock than a big dramatic looking wound on his chest? Like with real estate, location is everything, and this week we’re talking about infections in a location that we take very seriously – joints.

In its most basic sense, a joint is a place where 2 or more bones meet, along with the cartilage that covers the bone ends, and a joint capsule with a synovial membrane that secretes fluid to lubricate the joint. Most types of joints have movement of some sort – hinging like your knee or moving in multiple directions like your shoulder. It’s the same for your horse. Think about the joint capsule like a protective balloon around the joint. It’s a really important place, sealing the joint space and providing nutrition and lubrication to the cartilage. When infection gets inside that space, there can be career ending or life-threatening consequences. That’s why my docs don’t mess around when a joint infection is on the line.

These locations that are surrounded by a fluid-secreting synovial lining are called synovial cavities. There are so many synovial cavities in a horse, especially in the legs! And it’s not just joints, but tendon sheaths and bursae too, which are similarly worrisome if they get infected. That’s why my docs’ knowledge of anatomy is so important. A wound in one spot might not be that big of a deal, but a wound an inch away could be in a synovial cavity. The treatment and prognosis could be vastly altered by just a tiny difference in location.

How do Joint Infections Happen?

The answer is a bit different depending on whether it’s a mature horse or a foal. In foals, bacteria usually get into the joint through the bloodstream. The infection starts somewhere else in the foal, like the umbilicus or the lungs, and then bacteria travel in the blood until they arrive in the joint. This is especially problematic when foals don’t get enough immunity by suckling high quality colostrum right after birth, causing failure of passive transfer.

Adult horses most commonly get joint infections from wounds that enter the joint space, bringing debris and bacteria inside. Since it’s the same for a tendon sheath or bursa infection, we’ll just use joints as our example from here on. The wound could be an obvious laceration leaving little doubt that the joint has been compromised, but it could also be a tiny puncture wound that leaves no evidence of the injury.

Springhill Equine Veterinary Clinic

Joint infection can also rarely be seen as a complication of joint surgery or joint injection. That’s why you see all the scrubbing we do before joint injections. It’s not common to have a problem, but my docs will still be very careful with sterility.

Signs of Infection

The first and most important thing is if your horse has a wound anywhere near a joint, call my doc immediately. This is not the time to take a wait and see approach. Besides the wound itself, you might see lameness starting within hours to days, swelling in and around the joint, or sometimes fluid draining from the wound. It’s important to remember though, that if the joint has an open wound and is draining fluid, it may not show lameness or swelling yet. That doesn’t mean it’s not a big problem, so don’t put off calling my doc! If it’s been going on a while, the horse may have a fever. In a foal, the fever may be the first thing that occurs even before the joint swells up. No matter which of these you see first, the moral of the story is to call my doc and not mess around trying home remedies.

How We Diagnose a Joint Infection

When there is a wound near a joint, my doc will clean the wound and then explore it to find out if it communicates directly with the joint. She may put on a sterile glove and feel within the wound itself. She may insert a sterile instrument into the wound to track which direction it goes. An x-ray can be used to look for bone abnormalities caused by infection or to help with determining if the wound communicates with the joint.

A fluid sample can be collected from the joint to test for infection. Normal, healthy joint fluid is clear, pale yellow in color, and somewhat stringy rather than thin like water. Fluid from an infected joint may turn cloudy, watery, and sometimes change color. There are several lab tests that can be used to determine normal from infected joint fluid.

My doc may inject the joint with sterile saline from a site distant from the wound to pressurize the joint. If there is communication between the wound and the joint, the pressurized fluid will leak from inside the joint out through the wound. If there is no current communication, no leakage will occur.

If any of these methods determine your horse has an infected joint, you’ll have to start treating quickly and aggressively.

Springhill Equine Veterinary Clinic

How an Infection is Treated

Your horse will need his joint flushed out with large volumes of sterile fluid. This is best done under general anesthesia at a hospital. The gold standard is to use an arthroscope to inspect the joint surfaces, look for debris, and deliver a high flow of fluid to rinse out infection. He’ll also need powerful antibiotics given through his vein. Antibiotics are often injected directly into his joint or the region of infection as well. It’s important for the horse to be comfortable enough to bear weight on his injured leg and prevent too much stress on his other legs, potentially causing laminitis, so he’ll receive anti-inflammatory medication to reduce swelling and pain.

A joint infection can be difficult to treat, especially if the infection has been present for a while before treatment begins, or the bone or soft tissue structures are involved. So when there’s a wound on your horse’s leg, calling my doc quickly will give your horse the best chance to get the treatment he needs.

Until next week,

From Rescued to Reliable: Teaching your Animals to Trust

From Rescued to Reliable: Teaching your Animals to Trust

Mar 25, 2024 | Rescue, Training

Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Congratulations from your favorite clinic mouse Whinny, dear pet owner, on your noble act of rescuing an animal in need! You’ve welcomed a new member into your family, complete with fur, feathers, or hooves, and embarked on a journey of companionship. However, as the dust settles and the honeymoon phase fades, it’s time to address the elephant—or rather, the misbehaving pet—in the room. While rescue status may earn sympathy points initially, it’s high time we retire the excuse that poor manners are simply a byproduct of past trauma. In this blog, we’ll delve into the art of transitioning a newly rescued animal into a refined and well-behaved companion, regardless of its origin story.

Before you think me an overly opinionated mouse, let me remind you that well-behaved animals are confident animals that you can have all kinds of fun experiences with. Dogs, cats, horses, goats, and even sheep all have to have a minimum standard of behavior to receive veterinary care, grooming services, and nail or hoof trimming services without needing extra expenses like sedation or even anesthesia. Not to mention, my doctors have to work with with hundreds of animals every week. That majorly increases the chances of an injury if their patients (your pets!) aren’t well behaved. Mice tend to be exempted from this, as we hold ourselves to a much higher standard. But I digress.

An emergency veterinary visit is NOT the time to be training your animal. Horses should know how to be haltered and load into a trailer BEFORE they have to come to the clinic for an eye ulcer. Dogs should be comfortable walking on a leash and being held before they have to come in for vomiting. Cats should be exposed to their cat carrier before you have to catch them for us to come out and vaccinate. Goats and sheep need to have been handled before and be caught prior to my doctors getting to the farm. Your animals are more likely to be okay with being caught by you, their most favorite human, than our doctors and technicians, who seem to be, quite literally, strangers with needles (and it’s hard to argue with that perspective!).

Now that I’ve convinced you of the necessity of working with your rescued critters before they meet my doctors, let’s go over some techniques for all the different species!

Desensitization Techniques

Dogs

   – Handling: Start with gentle touches and gradually increase the level of interaction, rewarding calm behavior. Work on holding them in a standing, sitting, and lying position; pick up their paws, open their mouth, and lift their tail.

   – Vet Visits: Make visits positive experiences by frequent trips for treats and socialization, not just during emergencies. Everyone here at the clinic loves to see pups when they’re not sick. Just give the awesome office team a call to let us know you’re swinging by, and we’ll provide your pup with pets and treats (maybe I’ll even share some of my cheese!).

   – Collaring and Leashing: Introduce these gradually, associating them with enjoyable activities like walks and playtime.

Companion Animal Clinic at Springhill Equine

Cats:

   – Handling: Respect your feline friend’s boundaries and allow them to initiate physical contact, rewarding them with treats for accepting handling. Teach your rescued kitty that human hands can provide positive touches. Our crew loves cats and always starts with chin scritches and nice pets, but if they haven’t learned that those are nice, then they may never relax with us.

   – Vet Visits: Familiarize your cat with their carrier and the car ride to the vet by incorporating these into their routine with positive reinforcement. Leave the carrier open in their favorite room. Occasionally toss treats into the carrier for them to find. It should be a positive place they can hang out in that only sometimes acts as a portal to the vet office.

   – Collaring: Use lightweight, breakaway collars, gradually increasing wearing time and associating them with treats. Cats should wear collars, just like dogs, in case they get out or lost.

Companion Animal Care at Springhill Equine Veterinary Clinic

Horses

   – Handling: Begin with basic groundwork exercises to establish trust and respect, gradually introducing grooming and handling equipment. All horses–and donkeys!–should be comfortable picking up all four feet when asked, having their mouth and ears looked at, and their tail lifted. Bonus points if you also get them comfortable with their bellies being touched!

   – Vet Visits: Practice trailer loading and short trips to simulate vet visits, rewarding calm behavior throughout the process. You can even mimic vaccine injections and blood draws by using the tip of a pen on your horse’s neck. Showing your rescued horse that you will teach them what is going to happen at the vet before it does will increase their trust in you and in my doctors.

   – Haltering and Leading: Teach your horse to yield to pressure on the halter and lead rope, reinforcing with treats and praise. This is one of the most important things! If you can’t halter your horse or donkey, the veterinarian or technician most likely won’t be able to. If you know your rescued horse has some fears around the halter or typically takes a while to be caught, make sure you give yourself plenty of time to accomplish that prior to the veterinarian arriving. Donkeys especially are smart enough to recognize a strange vehicle and will make themselves scarce when that Springhill Equine truck pulls up if they’re not already caught.

Springhill Equine Veterinary Clinic

Goats

   – Handling: Approach goats calmly and quietly, using positive reinforcement such as treats or scratches to encourage desired behavior. Goats are naturally skittish, but can learn to trust people with time. If you rescue your goats when they are already adults, it’s especially important to spend lots of time with them, showing that approaching humans gets them rewards.

   – Vet Visits: Familiarize your goat with the process by practicing handling and restraint at home, and rewarding them for calm behavior. Goats and sheep can actually become quite distressed if they have to be chased to be caught for medical care. If they are already compromised with illness, that distress can very occasionally push them over the edge. Take the time to make restraint, lifting feet, looking in mouths, and lifting tails a routine part of life. Build that trust in the trust bank!

   – Leading: Introduce a collar or halter and lead gradually, starting in a familiar environment and progressing to short walks with positive reinforcement. Goats are extremely trainable given the right reinforcement. Large goats are much easier to work with when they come to the clinic if they will walk on a lead.

Springhill Equine Veterinary Clinic

All animals have a trust bank. The more positive experiences you can put into it, the easier it is to balance the negative experiences. Think about it: if every time you got in an elevator, you were poked with a needle, you’d do your very best to avoid elevators. Similarly, if the only time your horse is haltered is for vet visits where they get vaccinated and have blood drawn (both requiring a needle), they will only get worse for being haltered. This applies doubly to your rescued animals who already have a negative balance in their trust bank. The first steps are learning to trust you, but it can’t stop there, they have to learn how to trust new experiences too.

In conclusion, while the journey from rescue to refined pet may have its challenges, there’s no excuse for indefinitely attributing poor behavior to a pet’s past. By employing desensitization techniques tailored to the species-specific needs of your new friend, you can transform them from a rough gem into a polished companion worthy of admiration. So, let’s bid farewell to the it’s a rescue excuse and embrace the transformative power of patience, consistency, and time spent together. After all, manners maketh the pet.

Until next week,

Dental Health for Dogs and Cats

Dental Health for Dogs and Cats

Mar 18, 2024 | Dentals

Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Hey there, pawsome pet parents! Whinny the clinic mouse here, your furry friend’s favorite informant from Springhill Equine Veterinary Clinic where we just finished moving into the new Companion Animal Clinic addition! Today, I’m squeaking into the limelight to chat about a topic that might not be as glamorous as chasing feathers or curling up in a sunbeam, but is crucial for your four-legged buddies: dental health!

The Whole Tooth and Nothing but the Tooth: Why Dental Health Matters

You see, dental health isn’t just about preventing bad breath (although we’d all appreciate it if Fido’s kisses were a bit more pleasant, wouldn’t we?). It’s about maintaining the overall health and happiness of your furry pals. Just like you schedule regular check-ups with your own dentist, our pets need some dental TLC too!

Dental issues in dogs and cats can spiral into more serious problems, affecting the heart, kidneys, and liver. Imagine that! Something as small as a toothache could lead to bigger health concerns. But before we talk about keeping those chompers chomping, let’s learn a bit more about them.

Dog Dentition

Companion Animal Clinic at Springhill Equine

Dogs, with their diverse shapes and sizes, have an equally diverse set of teeth to match. Puppies start off with a set of 28 deciduous (baby) teeth, which eventually give way to 42 permanent teeth as they mature. The canine dental formula for adult dogs is usually represented as I3/3 C1/1 P4/4 M2/3, indicating the number and types of teeth in one half of the mouth. Let me break it down for you:

Incisors (I): These are the tiny front teeth designed for grasping and nibbling. Dogs typically have three pairs on the top and three on the bottom.

Canines (C): Known as the “fangs,” canines are designed for tearing and holding onto objects. Dogs have one pair on the top and one on the bottom.

Premolars (P): These more flat-topped teeth are situated behind the canines and are essential for shearing and grinding. Dogs have four premolars on the top and four on the bottom.

Molars (M): Positioned at the back of the mouth, molars are the heavy-duty grinders responsible for breaking down tough food. Dogs generally have two or three molars on the top and three on the bottom.

Dogs are classified as diphyodonts, meaning they go through two sets of teeth in their lifetime–just like horses and most other mammals. Their sharp canines and robust molars serve them well in their varied roles, from hunting and chewing to gnawing on your favorite shoe.

Feline Dentition

Companion Animal Clinic at Springhill Equine

Now, let’s turn our attention to our feline friends, whose teeth are a symphony of sleek efficiency. Cats, like dogs, are also diphyodonts, starting life with 26 deciduous teeth and transitioning to 30 permanent teeth. The feline dental formula is usually represented as I3/3 C1/1 P3/2 M1/1, showcasing their unique dental structure:

Incisors (I): Front and center, incisors help cats grip and nibble. They have three pairs on the top and three on the bottom.

Canines (C): Cat canines are formidable, designed for piercing and tearing into prey. They have one pair on the top and one on the bottom.

Premolars (P): Cats have fewer premolars compared to dogs, with three on the top and two on the bottom. These teeth are efficient at slicing and shearing.

Molars (M): Molars in cats are fewer in number but still play a crucial role in grinding food. Cats typically have one molar on the top and one on the bottom.

Felines, being obligate carnivores, have specialized teeth adapted for their meat-centric diet. Their razor-sharp canines and slicing premolars are a testament to their hunting prowess in the wild, but they do a good job with kibble and wet food as well!

Maintaining the health of each tooth is essential for your pet’s overall well-being. Regular dental care, including brushing and professional cleanings, ensures their teeth stay in top condition, allowing them to chew comfortably and avoid dental issues that could impact their overall health.

Why Dental X-rays are the Cat’s Meow

Companion Animal Clinic at Springhill Equine

Now, let’s talk about dental X-rays. These are like superhero goggles for our veterinarians, allowing them to see what’s happening beneath the surface. In dogs and cats, most dental diseases lurk below the gumline, and without X-rays, it’s like trying to solve a jigsaw puzzle without all the pieces.

We want to catch dental issues early on, before they turn into major concerns. Dental X-rays help us do just that, ensuring we get the full picture of your pet’s dental health. It’s like having a treasure map for your pet’s mouth – X marks the spot where we need to focus our attention!

Now, let’s get real for a minute. Addressing dental care early is like catching a snowflake before it turns into a snowball. Trust me, I know a thing or two about snowballing dental problems! By taking action early on, you save your pet from the discomfort of toothaches and yourself from hefty vet bills down the line.

Imagine this: your pet’s teeth are like little soldiers defending their kingdom. If you arm them with regular dental care, you’re setting up a fortress against dental diseases. So, why wait until those little soldiers are waving the white flag? Start early, stay ahead, and keep those pearly whites shining bright! Dogs and cats can be super stoic about oral pain and discomfort, so don’t trust the fact that they’re still eating and playing and assume they have no dental issues.

To Brush or Not to Brush

Now, I know what you’re thinking: Whinny, how do I keep my pet’s teeth in tip-top shape at home? Well, my pals, the answer is simple – the toothbrush tango! Yes, brushing your pet’s teeth is a great way to maintain their dental health. Regular brushing won’t remove tartar and plaque buildup that is already there, you need a veterinarian to perform an anesthetic dental evaluation and cleaning for that, but it can delay the formation of more tartar. It may sound daunting if you’ve never thought about sharing a nighttime routine step with your dog or cat, but if you start slow and introduce the concept gradually, your furry friend will jump on the bandwagon to a healthy smile with you!

But hold your horses! Before you grab any ol’ toothpaste, make sure it’s pet-specific. Human toothpaste contains ingredients that can be harmful to our pets, and we don’t want to turn a dental health routine into a dental disaster. Choose a toothpaste designed for dogs or cats, and your pet will thank you with a gleaming grin!

How about all of those commercials you see on TV and products in pet stores that advertise dental health benefits with no work? Well, just like most “As-Seen-On-TV” products, these are generally really not worth it. There is a way to find the best options though, and that is to look for the official VOHC Seal. VOHC stands for Veterinary Oral Health Council. The Mission of the Veterinary Oral Health Council is to review products for the VOHC’s standards for effective plaque and tartar control in animals when used as directed. They review submitted data to ensure it meets the clinical requirements to receive the Seal of Acceptance. When a product demonstrates dental efficacy, the VOHC Seal of Acceptance is awarded. The Seal can be for slowing progression of plaque, calculus, or both.

 If you don’t want to spend your Saturday hunting for this seal in the pet store, you can visit https://vohc.org/accepted-products/ to see all the options available for both dogs and cats.

Conclusion

Alright, my pet-loving companions, it’s time to wrap up our toothful tale. Remember, dental health is no small matter – it’s the key to unlocking a world of well-being for your four-legged pals. From anesthetic dental cleanings to dental X-rays, we’ve covered the whole shebang. So, take a moment to appreciate those pearly whites and consider scheduling a dental check-up for your pet at Springhill Equine’s Companion Animal Clinic. Together, we’ll keep those chompers in top-notch condition, ensuring your furry friends live their happiest, healthiest lives.

Until next week,

Granulosa Cell Tumors in Mares

Granulosa Cell Tumors in Mares

Mar 11, 2024 | Granulosa Cell Tumors, Mares

Whinny’s Wisdoms

Springhill Equine Veterinary Clinic

Spring is a-peeping around the corner, days grow longer, and the mares in the barn…well, they can get a little…interesting. Now, I, Whinny, am a field mouse of refined tastes (cheese, anyone?), and I appreciate a good mare’s temperament as much as the next critter. But sometimes, their behavior takes a turn for the puzzling. Is it just springtime shenanigans, or something more concerning?

We all know hormones are powerful little messengers in the body, like tiny knights delivering chemical decrees. But when there’s a surplus, well, chaos can ensue! In mares, one culprit behind this hormonal havoc is a sneaky villain called a granulosa cell tumor (GCT). Now, this might sound scary, but listen close – these tumors are usually benign, meaning they don’t spread like wildfire. However, they’re like mischievous imps, messing with the delicate hormonal balance and causing a whole host of problems.

Imagine a mare’s ovary. Normally, it’s a well-oiled machine, producing just the right balance of hormones for a smooth operation. But a GCT is like a rogue factory, churning out excess hormones like estrogen and testosterone. This throws everything out of whack, leading to a symphony of unwanted behaviors.

One telltale sign is a sudden shift in personality. A sweet-natured mare might morph into a grumpy Gus, exhibiting aggression and even acting stallion-like, with mounting and dominance displays (not cool, dude!). This is all thanks to the testosterone overload, turning our gentle friend into a temporary testosterone-fueled whirlwind.

Another red flag is a disruption in the mare’s reproductive cycle. Normally, mares experience regular estrous cycles, which is like their own internal calendar for breeding. But with a GCT, things can go awry. Persistent anestrus can occur, meaning the cycle disappears altogether, putting breeding plans on hold. On the flip side, some mares might experience continuous estrus, essentially being “in season” all the time. This can be frustrating for both the mare and her handler, as she might exhibit classic estrous behaviors like squealing and frequent urination.

Springhill Equine Veterinary Clinic

Now, before you panic if your mare seems a little off-kilter, here’s the good news: GCTs are detectable! My doctors have a toolbox of tricks to diagnose the problem. One method is rectal palpation, or a transrectal ultrasound. Think of it like a high-tech peek inside, allowing my docs to feel for an enlarged ovary, a signature symptom of a GCT. An ultrasound will show a very large ovary with tons of tiny follicles. The appearance is often described as a honeycomb. But that’s not all! They can also use blood tests to measure levels of equine inhibin, anti-Müllerian hormone, and testosterone to see if they’re out of balance.

Of course, sometimes mares can be grumpy for reasons unrelated to GCTs. Maybe she has a sore tooth or an ache in her leg that’s making her cranky (ouch!). So, a general checkup is crucial to rule out other potential causes of behavioral issues.

But let’s say the diagnosis confirms a GCT. Fear not! Treatment is available, and the most common option is surgery. Here’s the cool part: this surgery can often be done with the mare standing! Vets use a laparoscopic approach, which sounds fancy but basically means they make a tiny incision in the flank and use a special camera to remove the tumor. Minimally invasive and efficient – that’s what I call a win-win!

GCTs might be a challenge, but with proper diagnosis and treatment, mares can get back to their normal, well-behaved selves. The key is to be observant and consult your vet if anything seems amiss. After all, a happy and healthy mare makes for a happy barn, and that’s something every field mouse can appreciate!

Until next week,
