I have had a couple of cases of mastitis on my farm in the
past. Mastitis is a general term for an infection in the udder. Most mastitis
is caused by Staph bacteria but it can be caused by other pathogenic bacteria.
Staph is the same bacteria that cause MRSA in hospitals. Staph lives on the
skin and circulates in the body. Sometimes it gets where it shouldn’t be and
causes a problem. Staph inside the udder is a problem because milk is a perfect
media for growing bacteria and Staph can proliferate wildly in there. This
proliferation causes the symptoms associated with mastitis.
Topical Staph infection is seen as little whitehead pimples
covering the udder skin. The pimples don’t normally cause problems other than
looking alarming. Topical infection normally occurs when the udder is moist due
to wet living conditions or through milking technique. This infection can be
cleared up by carefully washing the udder before and after milking with an
antiseptic solution. FightBac teat spray works well when sprayed on the pimples.
Resist the urge to pop the pimples because this will just spread the bacteria.
Be careful to wash your hands in between goats when milking in order to not
spread the infection.
Staph abscesses are not uncommon in goats prone to mastitis
infection. A Staph abscess is a localized infection and usually presents as
hard ball between the size of a pea and a golf ball, located just under the
skin of the udder. Sometimes the abscess will burst and drain. I have had luck
with carefully opening Staph abscesses with a large needle and then expelling
the pus into a paper towel. I wear disposable gloves, spray the abscess with
disinfectant before and after opening, and use a sterile needle. The gloves and
anything that has pus on it is burned in order to get rid of the contamination.
Once the abscess is cleaned, I take a tube of ToDay mastitis treatment or
SpectraMast mastitis treatment and fill the abscess with this antibiotic. I
repeat the cleaning and antibiotic treatment until the abscess is dried up.
Staph mastitis occurs when the bacteria are inside one or
both sides of the udder. It is very important to keep a CMT (California
Mastitis Kit) on hand during milking season in order to test the goats weekly
for mastitis. This way you can track any changes in the milk and make sure that
the goats do not have subclinical (non-symptomatic) cases of mastitis.
Sometimes only one side of the udder is infected. In any infections, it is
imperative that you do not spread the bacteria from infected udder halves to
uninfected ones. Make sure the infected udder side is the LAST thing you touch
when milking. Do not go from infected to uninfected. To treat mastitis inside
the udder, the goat will need infusions of an appropriate antibiotic. Not all
mastitis is killed by ToDay (the most commercially available mastitis
antibiotic). To find the correct antibiotic for the mastitis, it is essential
to get a culture of the infected milk done by a vet. Most veterinarians who are
familiar with cow dairys are capable of culturing goat milk. A house call may
not be necessary to get a milk culture done. Some vets will allow you to drop
off clean, fresh milk samples for testing at their office. Having a vet culture
the milk is important because they can pinpoint which antibiotic the bacteria
will be killed by and will be able to write a prescription for the right one.
Many strains of Staph bacteria are resistant to ToDay so using it without
testing will not cure the problem. Follow the directions on the box to treat
your goat.
Sometimes mastitis can be systemic and not isolated to the
udder. I have had two cases on my farm where goats became feverish, stopped
eating and were sick from systemic mastitis. The infection had moved from their
udder into the rest of their body to make them sick. I treated this by giving
the goat shots of Penicillin, along with teat infusions of mastitis antibiotic.
If your goat is showing signs of fever and not eating, look at their udder
first. They may have systemic mastitis and will need not only their udder
treated, but the rest of them treated as well.
Most goats who suffer from any of these types of mastitis
will be prone to recurrent infections throughout their lifetime. Mastitis
signals that the goat carries some form of pathogenic bacteria, typically
Staph, on their skin or in their surroundings. Some goats have udders shaped in
ways that make them more susceptible to mastitis. Goats are more prone to mastitis
when they have teats very close to the ground, or with loose teat sphincters
that leak, or with floppy teats that can get stepped on. They can also re-infect
themselves from time to time. If you have a goat with multiple cases of
mastitis, it may be a very good idea to retire her from breeding in order to
save her from future infections.
When drying off a goat who has had mastitis during her lactation, it is a good idea to treat her with a mastitis dry treatment. A dry treatment is an antibiotic that is formulated to be infused into the udder and left there during the dry period. It helps to clear up any bacteria that may be trapped in the udder after drying off. ToMorrow is a commercially available dry treatment. A dry treatment not only helps while the goat is not lactating, but it can help prevent mastitis within the first few days of freshening. One of my goats freshened with mastitis because I didn't use a dry treatment on her. Her udder was hot, painful to the touch, and producing chunky infected milk right after kidding. I was lucky I had frozen colostrum on hand because all of her colostrum was not useable until the infection was cured.
