Equine strangles, also known simply as “strangles,” is a highly contagious bacterial infection that affects horses, ponies, and other equids. It is caused by the bacterium Streptococcus equi subspecies equi (S. equi). Strangles is characterized by abscesses and inflammation of the lymph nodes in the head and neck area, leading to symptoms such as fever, nasal discharge, difficulty swallowing, and swelling of the lymph nodes.

Here are some key points about equine strangles:

  1. Transmission: Strangles is primarily spread through direct contact between infected and susceptible horses. This can occur through nasal discharge, pus from abscesses, shared water and feed troughs, tack and equipment, and even human handlers who come into contact with infected horses.
  2. Clinical Signs: Horses with strangles typically develop symptoms within 3-14 days after exposure to the bacteria. Common signs include fever, nasal discharge (often thick and purulent), coughing, difficulty swallowing, and swelling of the lymph nodes under the jaw, giving the appearance of a “strangled” throat. Abscesses may rupture and release pus, which can further spread the infection.
  3. Diagnosis: A veterinarian can diagnose strangles through clinical signs, examination of lymph node abscesses, and laboratory tests such as bacterial culture or PCR (polymerase chain reaction) testing.
  4. Treatment: Treatment of strangles typically involves supportive care, including drainage of abscesses, pain management, and antibiotics (such as penicillin or trimethoprim-sulfamethoxazole) to control the bacterial infection. Isolation of infected horses is crucial to prevent the spread of the disease.
  5. Quarantine and Biosecurity: Quarantine measures should be implemented to prevent the spread of strangles on a premises. This involves isolating infected horses, implementing strict hygiene practices, and monitoring all horses for symptoms. Quarantine can last several weeks until all infected horses have recovered and tested negative for the bacteria.
  6. Vaccination: Vaccines are available to help prevent strangles, but they are not always 100% effective. They may reduce the severity of the disease and the risk of transmission but do not provide complete immunity. Consult with a veterinarian to determine the appropriate vaccination strategy for your horses.
  7. Complications: Strangles can lead to various complications, including guttural pouch infections, pneumonia, and bastard strangles (when the infection spreads to other parts of the body). These complications can be severe and require specialized treatment.
  8. Long-term Effects: While most horses recover from strangles with proper care, some may become carriers of the bacteria and shed it intermittently without showing clinical signs. These carrier horses can serve as sources of infection for other susceptible horses.

It’s important to consult with a veterinarian if you suspect strangles in your horse or if you have concerns about preventing its spread. Early detection and proper management are essential to controlling this contagious equine disease.

First 24 hours:

Have a veterinarian perform a newborn foal exam and pull blood for assessment of Passive Transfer (i.e., foal’s blood IgG levels after consumption of colostrum).  Any irregular findings or concerns during this visit can then be discussed and a plan created to move forward with to try and maximize the foal’s neonatal health and long-term success.  This is also a crucial time to identify any limb conformation issues and make a plan for either corrective trimming/shoeing or schedule for re-evaluation to provide treatment during times that maximize the foal’s natural growth periods to correct issues and, in some cases, caught early enough avoid surgery and/or long-term conformation issues that will affect lifetime performance.

Day 1 thru Day 3 of Life:

1 Month of Age: Any questionable limb conformation should be evaluated by a veterinarian, as in some cases such as fetlock varus/valgus (i.e., point of limb angulations starts at fetlock), corrective hoof trimming needs to start NOW.

2-3 Months of Age: Earliest recommended 1st Deworming: recommended deworm with a fenbendazole or oxibendazole.

Consult with veterinarian about starting vaccination of foal early if mare was not vaccinated or vaccination history is unknown, especially for vaccination protection from Tetanus, Rabies, & mosquito born viruses like West Nile, Eastern/Western Encephalitis

4 Months of Age: 1st Vaccines against: Tetanus + Eastern/Western Encephalitis+ Equine Herpes Virus (Rhinopneumanitis) & West Nile virus Vaccine

Foals will need 2 additional boosters of this vaccine combo roughly every 4 weeks for a total of 3 shots; to maximize West Nile antibodies (i.e., protection) it is given as its own shot for initial dose Rabies. Foals will need 1 additional booster of this vaccine

5 Months of Age: 2nd boosters against: Tetanus + Eastern/Western Encephalitis+ Equine Herpes Virus (Rhinopneumanitis), West Nile virus Vaccine & Rabies (FINAL booster for Rabies regime)

6 Months of Age: 3rd booster against Tetanus + Eastern/Western Encephalitis+ Equine Herpes Virus (Rhinopneumanitis) & West Nile virus Vaccine (final)

7 Months of Age: 2nd Deworming (ideally timed around weaning) BASED on FECAL EGG COUNT to determine which product will be most effect (e.g., using the kind of worm eggs present in fecal egg count to decide if fenbendazole or ivermectin or pyrantel is the dewormer of choice.) ***It is not recommended that moxidectin (e.g., Quest or Quest Plus) be given to horses less than year of age as it is very weight specific and easy to overdose resulting in illness and in some cases death of the horse

8 Months of Age: Recheck and revision of management plans for any angular limb deformities at level of the knee (i.e., carpal valgus/varus)

9 Months of Age: Finish up vaccine series if initial boosters were started at 6 months of age

10 Months of Age: Separate Colts from fillies and/or mares if not already done

11 Months of Age: Determine necessary paperwork & procedures for registering foal with Breed Registry if not already performed

12 Months of Age: 1st Annual Vaccines against: Rabies, Tetanus + Eastern/Western Encephalitis+ Equine Herpes Virus (Rhinopneumanitis) + Equine Influenza, & West Nile virus. Recheck Fecal Float and deworm pending what parasites are present; use a product containing praziquantel (e.g., EquiMax which is ivermectin + praziquantel) if this has NOT been previously used in treatment.  ***It is not recommended that moxidectin (e.g., Quest or Quest Plus) be given to horses less than year of age as it is very weight specific and easy to overdose resulting in illness and in some cases death of the horse

If you have any questions or concerns, please don’t hesitate to ask and happy horse growing!

Labor is divided into 3 stages:

  • Stage 1 begins with the onset of contractions and generally lasts one to two hours. Even in a normal delivery, the mare may stand up, lie down and roll several times in an effort to properly position the foal for delivery. During this phase, contractions move the foal through the cervix and into position in the birth canal. The fetal membranes (allantois) may become visible at the mare’s vulva. When the sac breaks, signaled by a rush of fluid, stage one ends.The rupture of the allantoic membrane and rush of placental fluids may be confused with urination.

  • Stage 2 is the actual expulsion of the foal. This phase moves relatively quickly. If it takes more than 30 minutes for the mare to deliver, there is most likely a problem. If there is no significant progress within 10 to 15 minutes after the membranes rupture, call your veterinarian immediately. If labor seems to be progressing, wait and watch. Normal presentation of the foal resembles a diving position, with front feet first, one slightly ahead of the other, hooves down, followed closely by the nose, head, neck, shoulders and hindquarters. If you notice hoof soles up, the foal may be backwards or upside down, and you should call your veterinarian immediately. If you suspect any deviation from the normal delivery position, call your equine practitioner. The most deadly of foaling emergencies is a premature rupture of the chorioallantois, known as “Red Bag Delivery.”  If at any time during stage two you see red/maroon membranes covering the foal as it emerges from the vagina, the placenta must be rapidly torn open. The foal is detached from its blood and oxygen supply. Normal membranes that cover the foal are white or yellow and translucent.
  • Stage 3 labor begins after delivery and is the phase during which the afterbirth (placenta) is expelled. Most placentas are passed within 1-3 hours after the foal is delivered. If the placenta has not passed within 3 hours, call your veterinarian. A retained placenta can cause serious problems, including massive infection and laminitis.

Choosing the right stallion can be difficult and finding the right veterinarian is one of the most important aspects. Look for someone who specializes in breeding or has been breeding horses for many years. A skilled veterinarian will help make the process go smoother.

Consider everything you like about your mare; attitude, confirmation, performance skill as well as what you don’t like about her. Be critical and ask others. If your mare has been trained by a professional, ask the trainer for their opinion. Trainers get to ride a variety of horses and can give valuable feedback. When looking for a stallion you want to compliment your mare’s strengths and not double up on her weaknesses.

Are you breeding for a specific discipline, or a specific size? Are you planning on keeping the foal for your personal use or planning to sell it after it is weaned? Often, stallions who are more well know will bring better money than those less know in their industry.

When you have your thoughts on a stallion, talk to as many people about the stallion as possible. Ask about what they like about the stallion and what they would change if they could. Look at their offspring’s performance record. Have they been mostly ridden by a professional trainer or amateur riders? If you can, visit the stallion in person, do it. Pictures can be deceiving. This will also give you time to see what the stallion’s temperament is when you are around them.

Do research on your mare’s bloodlines. Look at what crosses have worked with her bloodlines and what have not. If you show competitively, this will be evident in show records. Remember, both mare and stallion bring their genetics to the table. If your mare is longer in the back and you don’t like that, than look for a stallion who is shorter in the back and can potential change that for you. Breeding to a stallion with the same confirmation as your mare, will only double your chances of reproducing the same confirmation.

Remember to ask plenty of questions. If this is your first-time breeding, schedule a breeding soundness exam with your veterinarian. https://www.allbreedpedigree.com This will help you understand where your mare is at reproductively before paying for a stud fee and finding out your mare is not suitable to be bred. Ask your veterinarian what the cost of breeding will be. Are there any hidden costs? Understand how much you are willing to spend on the process.

Ask if breeding with cooled shipped semen is less expensive than breeding with frozen semen, and what to consider in conception rates between the two. Veterinarians who specialized in breeding might know the stallion you are considering and have firsthand knowledge of his semen quality when it is shipped overnight via Fed-Ex or transported commercial airline cargo for same day insemination.

Lastly, make sure you fully understand the terms of the breeding contract. What type of semen are you purchasing, cooled shipped or frozen? What is the stallion’s availability for the breeding season? Does he have a show schedule? Is the stallion a carrier of diseases such as equine viral arteritis (EVA), hereditary equine regional dermal asthenia (HERDA) or hyperkalemic periodic paralysis (HYPP). Does the contract have a live foal guarantee, standing and nursing? If your mare does not get pregnant during the initial breeding year can you try again the following year and what are the additional costs to you? To avoid misunderstandings on the issue, mare owners should look for how the contract defines re-breed rights. Can you substitute an alternate mare if the one you originally chose is not a good candidate for some reason?

Horses with dental problems may show obvious signs, such as pain or irritation, or they may show no noticeable signs at all. This is because some horses simply adapt to their discomfort. For this reason, periodic dental examinations are essential to your horse’s health.

It is important to catch dental problems early. If a horse starts behaving abnormally, dental problems should be considered as a potential cause. Waiting too long may increase the difficulty of remedying certain conditions or may even make remedy impossible. Look for the following indicators of dental problems from the American Association of Equine Practitioners (AAEP) to know when to seek veterinary attention for your horse:

Oral exams should be an essential part of an annual physical examination by a veterinarian. Every dental exam provides the opportunity to perform routine preventative dental maintenance. Mature horses should get a thorough dental exam at least once a year, and horses 2 to 5-years-old should be examined twice yearly.

For more information about proper dental care, ask your equine veterinarian. Additional information is available on the AAEP’s website, www.aaep.org/horseowner.

Through the years, Bandalero Ranch has taught many stallions both young and old to use a phantom mare. Most stallions will mount readily and can be collected successfully with relatively few attempts. It is difficult to predict how a stallion will act until teaching begins. A stallion whose behavior is “quiet” or those stallions slow to breed may take more time due to their timidity, or low libido, however they will eventually use a phantom just as well as any other stallion once confidence and understanding is gained.

In our experience, the average stallion can take one to three sessions prior to a successful collection. Those stallions who have previously live covered mares may take additional sessions since they are initially confused when they are not permitted to mount the tease mare. Once a successful collection is achieved, two to three more collections to reinforce the behavior will provide us some predictability and reliability that he will perform when necessary.

We maintain a mare for teaching and general collecting purposes. This mare is quiet and shows estrus well which encourages each stallion and gives him confidence. Each session takes a team of three people; the stallion handler, mare handler and the collector/veterinarian. .The mare handler strategically places the mare next to our teasing partition, giving the stallion, mare and handlers safe access for teasing. In most cases, this is enough to stimulate the stallion. In special circumstances, the mare is positioned next to the phantom mare on the opposite side from where the stallion will be presented. The stallion has already been prepped and is led up so that he can tease the mare over the phantom. The person handling the artificial vagina must be prepared to collect the semen wherever the stallion mounts. If the stallion is being trained to use an in-line artificial vagina the person then helps the stallion guide his penis into the in-line artificial vagina. A young stallion does not always mount on the proper end and to insist that he does can result in frustration. Stallions are quick learners; once success is attained there will be improvement with each subsequent session.

If you are planning to stand your stallion, this teaching period is an excellent time to test your stallion’s semen for fresh cooled transport. Our 48 hour semen viability test will provide you with valuable information for marketing.

Myths of Equine Dentistry
Written by Carl Mitz, Bandalero’s Equine Dental Provider

These statements are simply not true! All horses require routine dental maintenance, from cap extractions, tooth extractions, floating, molar extractions, incisor extractions, wave complex reduction, and the list goes on. Proving routine dental care ensures the health and longevity of your horse.

Have your horse “vetted out.”
Your veterinarian should be contacted and requested to perform a pre-purchase examination of any horse you might consider purchasing.  A pre-purchase examination is entirely different from a veterinary examination pertaining to normal vaccinations, deworming, or any other sort of veterinary procedure.  Generally, horses are sold with no warranties, with some limits, and if the buyer elects not to have the horse “vetted out,” the buyer in most cases purchases the horse — AS IS.  That is, what you see is what you get.

Realize your limitations
Even if you buy a well-trained horse that has won numerous championships, there is no guarantee that you or your child will be able to reach the level of performance achieved by other riders with the same horse.  That is not to say that you will not achieve success, but horses are not much different from people in that various personalities get along better than others.  You should assume that your horse will respond differently to you than its previous owner, and we all hope the productivity established by such relationship is greater than that of the previous owner.

Ask questions
Most people hate to admit that there is something they do not know.  Consequently, many people do not want to ask questions that would, in their opinion, make them appear ignorant or less than expert.  The horse industry is very complex and operates under its own rules and traditions, independent of what one may perceive as normal in other areas of sales.  If you do not know something, ask questions . . . we are more than happy to assist you in any manner possible and it is important to us to know that you know what you are getting.  We will do everything possible to help you make a reasonable and rational decision regarding any purchase.  The ultimate decision must rest with the buyer and it is our objective to assist any prospective buyer in formulating and analyzing whatever issues the buyer may deem appropriate.

What you see is what you see is what you get!
Horses change hands from time to time and it is somewhat different than buying a car.  A horse may be injured and suffer permanent damage, or it may be abused from owner to owner causing certain behavioral traits which were apparent at one time and may not be apparent at others.  Realize that each horse-related transaction is different from the others, and each transaction must be evaluated on its own merits.
