Failure of Passive Transfer is when the foal does not consume an appropriate amount of antibodies from the mares colostrum, either from lack of production, poor quality, or physical separation from the mare. Foals rely on the antibodies from the mare’s colostrum to protect them during the first few months of life, and they only have a specific time window on when they can absorb them through the gastrointestinal tract. Without them, they are susceptible to infections and don’t have a great way of fighting them, and often times are lost due to neonatal septicemia.

This foal was born and another mare decided she belonged to her and not the real momma. On top of that, the real mother appeared to have poor milk production.

We intervened by running bloodwork, including a foal IgG SNAP test, which confirmed our suspicion that the filly needed our help. Due to the foals age, giving oral colostrum was no longer and option so we treated with intravenous hyperimmune plasma, IV fluid therapy, antibiotics, and prescribed domperidone to the dam to help with milk production. In the mean time the foal is going to stay on supplemental milk replacer.

A few quick takeaways:

👏 administer pre foaling vaccinations to pregnant mares about 30 days prior to their anticipated due date to help make their colostrum packed with antibodies to the foal.

👏 follow the 1-2-3 rule. The foal should be standing in 1 hour, nursing in 2 hours, and placenta passed in 3 hours. Early intervention of both mare and baby saves lives…if something isn’t right, do not wait!

I am starting to get more calls regarding breeding mares which makes me EXCITED for the year to come!! Here are some quick housekeeping items to consider for the upcoming breeding season:

1- READ your contracts and understand the policies that the breeding farm has in place for the stallion you’ve picked for your mare.

2- Make sure all of your contracts are paid in full prior to shipping

3- Start the season off with a uterine culture and cytology. These aren’t just random tests, and should be done when your mare is in heat. Taking a sample at the wrong stage of their cycle can give inaccurate results. It will save you time and money to make sure everything is at their best chance for conception, and more and more farms require negative cultures prior to shipping.

4- Make sure your mares are current on their annual vaccinations, coggins, and dental care prior to starting the breeding process.

5- If you have a problem mare or had any issues last year, schedule a time to consult with your veterinarian on a plan for this year. We can help troubleshoot what’s going on and recommend a plan to get our best chance of success on a pregnancy.

Remember, there are multiple factors that go into getting a mare pregnant and a healthy foal on the ground. It is called the miracle of life for a reason, but we can do our part to make sure the factors we can control are taken care of to the best of our ability!

I’ve been getting several concerned questions and messages regarding the recent news of a couple of horses testing positive for EIA in Waller and Montgomery county.

Most of the questions I have been getting relate to how easy it is for one horse to spread it to another.

I am attaching a website from USDA APHIS that explains EIA for those who want a long read.

Cliff notes version- EIA is a virus that is spread via blood, traditionally from biting flies and more and more often now through iatrogenic transmission by reusing needles, sharing needles, IV sets, etc. There is no cure for the infection and if a horse is truly positive, they are carriers for life. Because of this the horse must either be euthanized or permanently quarantined with strict specifications on the size of the quarantine area.

I do not feel there is any need to panic, this is why we perform annual Coggins Testing, but this is a good reminder to keep all of the horses on your property current on their EIA/Coggins test, use appropriate fly control practices, and to be sanitary and not reuse or share needles, which I hope none of my followers and clients do anyway!

Proper dental care is a necessity for your horses no matter what they do for a living.

I recommend that young horses in training receive their first oral exam prior to being sent to the c**t starter. Usually this is around 18-24 months old. At this visit, we check for wolf teeth (I like to pull them at castration time, but sometimes they aren’t there yet or it’s a stud c**t, and sometimes fillies have them too), loose deciduous teeth aka “caps”, and I will reduce any sharp enamel points that may interfere with chewing and riding. Depending on the discipline a bit seat may or may not be applied. I personally prefer a lighter bit seat, because taking too much tooth can cause pain and even permanently damage the tooth.

I then recommend every 6 month visits until the horse has lost all of it’s baby teeth. After that point most horses can get by with annual dental visits.

For adult horses, I recommend new purchases have an oral exam so we can diagnose any abnormalities or problems that need addressing, and then annual appointments unless we find issues that require more frequent visits.

By doing annual oral exams, you can maintain a healthy mouth and detect problems before they have reached a point beyond repair. I see this mostly with horses who are unregistered and their age was guesstimated at some point, and with owners who may not know that annual dental care is recommended. These horses typically present as weight loss cases, and I always do an oral exam for weight loss for this reason. Many times the teeth are aged, worn, and now require a special diet.

Long story short, there’s a multitude of reasons for annual dental care, but the bottom line is even if you don’t ride your horse at all, oral exams are a necessity for your horse to live it’s most healthy life.

Attached is a picture of a 4 coming 5 year old horse with an unknown dental history. I am terrible at taking before pictures, so this is a “during” picture, where you can see the ulcers at the back of the mouth. Thankfully, other than sharp enamel points the rest of the mouth was pretty unremarkable!

2023 is fast approaching, which means foals will be hitting the ground soon!! Here is my annual summary of preparing for foaling. And I apologize, it’s always long!

1- have a list of their breeding dates and due dates so you know when to give certain vaccines and when to start foal watching. By this point, you are hopefully current on giving your EHV-1 vaccinations either at 5,7, and 9 months or 3,5,7 and 9 months depending on the risk factors of your herd. Going by your estimated due dates ( I personally love the Dreamhorse Foaling Date Calculator which gives you vaccine reminders) you should vaccinate your pregnant mares about 4-6 weeks before their 340 due date with core vaccines plus any other vaccines your vet thinks may fit your breeding program. My personal mares get vaccinated for Flu/Rhino, Eastern, Western, Tetanus, West Nile Virus, Rabies. Some farms may also do more, so talk to your vet. By timing these vaccinations, you are stacking the odds in your favor for strong, potent colostrum. The antibodies in the mare’s colostrum are what the foal uses to protect itself while it’s own immune system learns the ropes throughout the first few months of life. THIS IS SO IMPORTANT and can save you vet bills and potentially your foal’s life!!!

2- Get in the habit of checking your mares at least once a day, but ideally I check them twice. I watch for mammary development, v***a elongation, and softening of the muscles around the base of the tail. Many, but not all, mares will wax prior to foaling. Many, but not all mares, will also drip milk prior to foaling. You can get the test kits and gadgets but nothing- n o t h i n g- replaces good observational skills. If you notice your mare has been heavily leaking milk for days on end, you should contact your vet prior to the foal’s birth and plan on giving plasma. Once again, that colostrum- if they drip it all out, the foal will not get enough antibodies and will be susceptible to infections. This is called Failure of Passive Transfer and it can be deadly if not addressed quickly. Even if everything happens just fine, it’s good practice to have your veterinarian check the baby at 24 hours old (or within reason during business hours) and measure their IgG levels. This can be done on the farm and can tell you whether the baby received enough antibodies from the mare’s colostrum. If you check at that point, your veterinarian easily administer IV plasma before the foal starts to show signs of FPT and systemic illness.

3- CHECK FOR A CASLICKS!!! For those who do not know, a caslicks is where a portion of the v***a is sutured together to help maintain a good seal keeping air and other debris out of the va**na. This is done usually because the mare’s conformation is lacking and she contaminates herself, which makes it hard to get her pregnant or maintain a pregnancy. But sometimes even maiden mares with normal conformation have a caslicks due to their job, like off the track horses or barrel horses... If you don’t remember if your mare has a caslicks or not, you can check yourself or have your veterinarian take a peek for you. I recommend having the caslicks cut 2-4 weeks from their due date. If you don’t have them cut, they can tear during delivery.

4- Get a plan together in case of emergency- Know what clinics see emergencies near you. Find out if sick newborns or dystocias (trouble foaling) is something they can handle. And find out their policy on emergencies- are you a regular client and if not, do they see emergencies for those who aren’t? Figure out your nearest referral center. Have a list of phone numbers handy BEFORE you need to find them!!

5- Get a foaling kit together!! The majority of mares are great at having foals quickly and without help, but even if everything goes perfect you need supplies. And if you need to intervene, it is best to be prepared. Have a relationship with a vet that sees emergencies before it’s an emergency. You can also send your mares to foal out at clinics or farms that offer those services if that suits your needs. Some ET facilities require their leased recips to be foaled out with professionals too, so check your ET contracts.

This is what I have in my foaling kit:
Towels
Scissors
Exam gloves and OB sleeves
OB l**e
Sterile L**e
Thermometer
Saline enemas ( you can find these at your local people pharmacy)
Vaseline (sometimes foal bottoms can get crusty and this can help with scalding)
Betadine or chlorehexidine to dip the navel (dip it at least two times during the first 12-24 hours of life)
Foal probiotics and anti diarrhea pastes. I personally keep FullBucket products on hand. They even make Foal starter kits that come with milk test strips too!
**check your horse trailer if you don’t haul often to make sure lights and tires and everything is in order in case you need to load up in case of emergency**

And finally, some quick “rules of thumb” regarding foaling.
There’s 3 stages of labor. The 1st stage is where the mare positions the baby. She is usually restless, may act colicky, and may be up and down and is uncomfortable. This may last hours. Stage 1 moves to stage 2 when the water breaks. **if you check on her too often she can and may hold off labor until you leave her alone. It is best to monitor where you aren’t constantly disturbing her**

Stage 2 is the active stage of labor. When the water breaks, a white bag should present shortly after. You should then see within the white bag two front feet and then the nose. ** 911 emergency is if you see a RED velvety bag instead of a white sac. If you aren’t sure what that looks like, google it, ask your vet or experienced friends, because you will need to intervene** For some mares this stage is very short, like 5 minutes, and in other mares it can last closer to 25-30 minutes. The biggest thing is there should be a clear progression of labor. If things aren’t moving forward, or you notice that the presentation is not normal- like no feet, or feet but no nose, or back feet, etc- call your vet and get a plan together.

Stage 3 is passing of the placenta. This sometimes happens pretty quickly after foaling, but can take up to several hours. Do not mistake the thin white amniotic sac for the entire placenta. That will come out, but you also need to see the thicker heavier sac (the chorioallantois) come out too. Check the placenta for tears or missing pieces. It should be a Y shape and should have ONE hole, the hole that the baby came out. If there’s holes in the tips of the Y shape or obvious pieces missing, or worse yet you see some membranes hanging from the mare AFTER 3 HOURS FROM BIRTH- do not pull it out- and call your vet. There are things we can do to facilitate getting the placenta out that won’t injure the mare or risk leaving pieces left behind inside.

The foal should be STANDING within ONE hour of birth, NURSING within TWO HOURS of birth, and the fetal membranes passed within THREE hours of birth.

** I will make another post of red flags and what to do for them in another post!!**

Today we performed a permanent tracheostomy in a horse under standing sedation.

Most commonly in our part of the country, permanent trachs are placed due to scarring in the nasopharynx from nasopharyngeal cicatrix syndrome. Chronic scarring can narrow the airway to the point it becomes a struggle for the horse to breathe.

Placing a permanent trach will cause the air to bypass the upper airway and breath from the permanent opening made into the trachea. This can be an intimidating surgery for horse owners, but for many horses, this greatly improves their quality of life. Although no more swimming as if they are deep enough they can drown!

Most common complications are post operative infection and dehiscence of the sutures. Sometimes the opening needs to be revised and widened. Less often, horses can experience tracheal collapse if too much of the tracheal rings are taken.

After the initial healing process, permanent trachs are low maintenance to keep clean.

I love before and after pictures of eyes!

This patient came in with a significant uveitis flare. He was brought in as soon as it was identified, and we placed a subpalpebral lavage to administer medications every two hours. The goal is to dilate the pupil, relieve pain and inflammation, prophylacticly treat for any infectious component, and save vision. He was also on systemic anti inflammatories.

The bottom picture is his eye today- the cornea is clear, the pupil is dilated, most of the inflammatory cells have consolidated and dissipated, and he is not squinting or acting painful. Lauren Davang Meighen Wharton Veterinary Clinic Amber Gallia Schoelzel

***WARNING-GROSS***

Retained fetal membranes!

Did you know the mare is supposed to pass her placenta within 3 hours of foaling? If she still has fetal membranes intact after this point, they are considered retained.

Retained fetal membranes do not take long to start to decay. The infection that comes from the dying tissue can cause life threatening complications like laminitis and sepsis.

This picture is of a placenta who the owner noticed had not been passed just prior to 3 hours post partum. The mare was brought to the clinic and treatment was started. She was closely monitored and once the placenta was passed it was inspected. This portion of the placenta had not touched the ground, so we flipped it over. You can already see how nasty this sucker was getting.

This patient was started on broad spectrum antibiotics, flunixin, and her uterus was copiously lavaged to remove any debris and fluid. Had her owner waited much longer, the outcome could have been much different !

Miniature horses and ponies should have annual oral examinations just like full sized horses. This mini has a significant underbite, causing uneven wear and overgrowth of the incisors. Due to the incisor malocclusion, she also had significant caudal and rostral hooks on her cheek teeth. We anesthetized her to correct her incisors, and then we were able to place a speculum in her mouth and address her cheek teeth. Cases like this I recommend checking every 6 months.

Uterine Cultures

Now is the time of year that everyone gets ready and excited for breeding season! Many breeding farms and stallion contracts require a negative uterine culture prior to shipping. And lots of people push for getting uterine cultures performed prior to breeding… but here are a few reminders:

Uterine cultures should be performed in conjunction with a reproductive exam and ultrasound. Interpreting a uterine culture should include comparing it to exam findings such as free fluid in the uterus, fluid in the va**na, endometrial cysts, or other abnormalities that may occur. Sometimes mares will culture negative or “clean” but have a bacterial biofilm, and if you just culture without looking at the mare or getting a detailed history, you may be frustrated a few months down the road. For complex cases like that, you may be better off doing a low volume lavage and culture the fluid versus a traditional culture with a double guarded swab.

If a mare is not yet cycling, you may get a uterine culture that falsely represents bacterial growth or lack of growth. The hormonal changes that occur during their cycle can make it easier or harder for bacteria to grow. So you want to make sure before you spend the money on a culture that it’s worth performing the culture at the visit; you may be better off postponing until she’s cycling and ready.

So long story short, it’s better to get an exam with an ultrasound in conjunction with a culture than picking and choosing things al a carte. Spending a little more money up front can save you headache and dollars later!!

Little fragment, big mess 😂
This horse had a deep laceration over the cannon bone months before, but the owner brought him in because one small portion of the wound would never heal fully. It would burst open, drain, then quiet down- only to repeat over and over. Radiographs were taken and a bone sequestrum was identified. This little piece of dead bone was taken out of the wound, which should now be able to close and finally heal.

This 2YO presented with head shaking and not wanting to accept bit pressure at the c**t starters. Like a good boy, he already had top wolf teeth removed at castration. But upon oral examination, we found two bottom wolf teeth! We also checked for premolar caps but none were loose, and I don’t pull them unless they are loose and ready. He was also in the process of erupting his first set of permanent incisors. All of these changes in their mouth can provide discomfort. It’s always good practice to have an in-depth oral exam and dental care when you send them off, or if their behavior changes under saddle. This guy will be feeling better and be ready to go back to work. Wharton Veterinary Clinic

***WARNING***

Graphic post! Posted with owner permission

This horse came in on emergency after getting caught in a fence. She had completely transected her extensor tendons on the right hind limb and had at least 8” of exposed cannon bone. She also had a very small laceration of her SDFT but not enough to compromise the integrity of the tendon. On the left hind limb she had severe lacerations over her hock, but miraculously missed any synovial structures.

We placed a few sutures on the skin to provide temporary covering of her bone, heavily bandaged her, and splinted her leg with a temporary PVC splint. She was placed on broad spectrum antibiotics, administered tetanus prophylaxis, and administered phenylbutazone for pain as needed.

After a week a more permanent brace was made for her so she could walk without knuckling over on the right hind limb. After a few weeks of bandage changes and stall rest with the brace she was sent home for at home care.

Yesterday we got an update that she is walking around without the brace and has learned how to place her foot on her own!

This was a nail biter of a case and I am so happy she is well on her way to recovery! She has some very dedicated owners who took on the challenge to save her life and I’m grateful to have had the opportunity to help! Wharton Veterinary Clinic
