What are Mastitis?

Mastitis is considered to be one of the most expensive diseases of large animals and can be fatal in certain cases. It is much more common in cattle than in horses, but lactating mares are still at risk for this painful condition. Not only is it painful for the mare, it can be dangerous for her foal as well. She will not be likely to let her foal nurse when she is in that much pain and the milk may not be as appetizing as well, leading to malnutrition. If your mare is acting as if her udder is painful or if you can see that it is visibly swollen, you need to take her to see an equine veterinarian. If you do not get sufficient treatment right away, abscesses or induration of the gland may occur.

Mastitis in horses is the inflammation of the mammary glands. Most often, this disorder affects mares within one or two months of giving birth but it can affect any mare of any age. If your mare’s udder is swollen sooner than six weeks before giving birth, you should call the veterinarian because it could be a sign that your mare is having an abortion. If your mare is lactating and her udder is swollen, the foal may not be nursing or there could be an infection or injury.

Symptoms of Mastitis in Horses

The most common symptoms that are usually noticed first are a swollen and hot udder and standing or walking abnormally. She may also not let her foal feed and may just seem generally unwell. Other common signs of mastitis are:

  • Painful and swollen udder
  • High body temperature
  • Depression
  • Walking stiff
  • Standing with legs apart
  • May kick foal away when trying to nurse
  • Milk changes consistency (lumpy or watery)
  • Abscesses
  • Death (rare)

Types

While there may be many types of bacteria and fungi that cause the infection, the most common are:

  • Aspergillus spp.
  • Coccidioides immitis
  • Gram negative bacteria
  • Streptococcus agalactiae
  • Streptococcus equi
  • Streptococcus equisimilis
  • Streptococcus viridans
  • Streptococcus zooepidemicus

Causes of Mastitis in Horses

Bacteria or fungi may be the cause, but it is important to know the cause of transmission. Some of the most commonly reported ways to transmit mastitis are:

  • Injury to udder that breaks the skin and causes infection
  • Insect bites
  • Dirty bedding material

Diagnosis of Mastitis in Horses

The veterinarian will not have any trouble diagnosing your horse if she has mastitis, although a thorough checkup is necessary to determine the cause of the mastitis. It is most often bacterial, but there are other causes such as fungi or parasites, so the veterinarian will start by getting your mare’s history. This includes medical and shot records, description of the symptoms, and when she last gave birth. Be sure to mention if there were any complications during birth and whether she is on any kind of medication.

A physical examination is done next, including height, weight, body condition code, palpation of abdomen, breath sounds, heart rate, respirations, body temperature, blood pressure, and reflexes. The veterinarian will also have you walk and trot your horse to see if she has any lameness and to watch how the muscles and joints function in motion. In addition, the veterinarian will be assessing your horse’s attitude, stature, conformation, and behavior.

Laboratory tests include a complete blood count (CBC), urine and fecal examination and culture, biochemistry panel, blood urea nitrogen (BUN), packed cell volume (PCV), and glucose level. The veterinarian will be looking for elevated neutrophils, leukopenia, and white cell count. The veterinarian will also get a sample of the fluid from your horse’s mammary gland to see if there are signs of inflammation, bacterial, and fungal culture. The samples must be taken from each teat, and care should be taken to maintain sterilization. The samples will be tested for cytological examination as well because the cultures often come back negative even when your horse has mastitis. Imaging with an ultrasound and x-rays of the mammary glands to help identify abscesses.

Treatment of Mastitis in Horses

Treatment for mastitis may be medication, therapy, or both. Therapy is most important to clear the infected tissue and milk that need to be removed. It usually includes hand milking your mare frequently to remove fluid and bacteria. Some of the other treatments are:

Medications

Some of the medications that may be used are trimethoprim-sulfonamide, combination of penicillin and gentamicin sulfate, non-steroidal anti-inflammatory (NSAID) medication for pain and inflammation, and there is a prepared mastitis treatment (marketed for cows) that can be injected into the infected mammary glands.

Therapy

Therapy includes frequent hand milking and hot packs alternated with cold packs to reduce pain and swelling. Hydrotherapy is also a good form of treatment.

Recovery of Mastitis in Horses

Prognosis is excellent if you get treatment from an equine veterinarian. One complication is a relapse, which happens in about 15% of horses. With proper treatment, your horse should be back to normal within 2-3 weeks.

If Treacle is improving, that is positive. If she has had a low level, resistant infection for years, it may take time to resolve. I hope that she does well.

Has Symptoms

Sore teats and excessive urination

My mare has pink teats and the flys go crazy for them so I am covering them in fly spray everyday, when I touch them she gets very upset which is unlike her, she is also urinating a lot too. She has not had a foal, is it possible for a mare to have mastitis without having a foal ? I wonder if a infection has got in due to the flys and constant products I am putting on. She recently finished a course of antibiotics as I thought she may have a urine infection due to the constant urination but nothing has changed since finishing the course.

Mastitis may occur in a non-lactating mare, but it is uncommon; you should really get your Veterinarian out to take a look to confirm and prescribe treatment as I cannot recommend the use of antibiotics without an examination first. Regards Dr Callum Turner DVM

Has Symptoms

walks out slow in am
one swollen teet
clear drippy discharge from teet
urine in stall decreesing

I'm leasing a 28yr old mare that developed a painful swollen teet w/ milky discharge a year ago and was treated with antibiotics that didn't make a difference. We were told to milk her and after a week blood came out. I then called a holistic vet and she said it was a tumor. The mare was put on a chinese stacis blocker called tan yu tang. At $100 a month with moderate relief in the beginning we couldn't afford treatment. Not sure what to ask a vet in regards to what it would cost for an estimate to treat her now, again since it never went away the first time? Any bloodwork that I should request? I just want her to be pain free in her last senior years.

Mercedes may benefit from an actual biopsy, although I am not sure, as i cannot examine her. if it is cancer, there may be few options for treatment, and she may need pain medications or antibiotics to keep the mass from becoming infected. your veteirnarian will be able to give you a better idea as to treatment options once they have seen her, and a visit with your veteirnarian would be the best thing to do at this point.

Thank you.

Has Symptoms

Mastitis

We have a maiden mare that foaled and did not have milk letdown, or very minimum. She did have colostrum and the foal was able to nurse what she had. After waiting to see if the foal reflexes helped with letdown, which was negative, I administered 2cc of oxytocin. Approx. 12 hours later the mare seemed to have mastitis dorsal the mammary gland. It seems that the glad has some milk and the hardness is restricting the filling of the gland on both sides.
I was thinking that massaging only one side at a time to see if this would bring it down into the mammary glad and milk it out,then proceed to the other side to repeat would be beneficial so the foal could still nurse the good milk.
Questions being: what antibiotic should I admin. and does this massage/ milking procedure seem to be the effective route?

Thanks

Without examining Mercedes, I'm not legally able to advise you on antibiotic therapy, unfortunately. Without seeing her, I can't determine if massaging the gland will help, or should be avoided, as different situations call for different therapies. It would be best to have her examined by a veterinarian to determine the cause of what is happening and get recommendations for appropriate therapy. I hope that all goes well for her.
