Transcript Caprine Mastitis: Management and Control

Caprine Mastitis:
Management and Control
Dr. Jerry Roberson
UT College of Veterinary Medicine
Definitions
Mastitis: inflammation of mammary
gland
 Mostly bacterial
 Mostly unseen inflammation
Subclinical vs Clinical
Mastitis
Subclinical: you can’t
see it.
Clinical: you can see
it.
Looks like
butter.
Clinical Classification

Mild clinical
– Abnormal milk
– NORMAL Doe

Moderate clinical
– Abnormal milk (+/- heat swelling, pain)
– Doe somewhat off

Severe clinical
– Abnormal milk (+/- heat swelling, pain)
– Obviously sick doe
Chronic Mastitis



Long duration
Can be subclinical
or clinical
Primarily contagious
pathogens
THE BUGS
Staphylococcus aureus






Most important
Contagious: spread from infected
udders
Creates chronic mastitis
Difficult to cure
Main cause of “Blue Bag”
Causes high somatic cell count (SCC)
CNS





25 + speices of coagulase negative
staphylococcus (CNS)
Most common udder pathogens
Minor pathogens?????
Prevent other major infections?
Live on body sites
Major Environmental
Pathogens

Coliforms
–
–
–
–

E. coli
Klebsiella
Pseudomonas
Pasteurella
Environmental
Streps
Coliforms: How are
they transmitted?
 Enter
via
the teat
canal
 Opportunist
Mycoplasma




Does not grow on routine bacterial
culture (requires a special agar)
Contagious
No successful treatment
May also be arthritis and ear nfections.
CAE (Caprine Arthritis
Encephalitis)





A virus
Cause Hard Bag
May be no other signs
No treatment
Consider a control program
Management of mastitis



They don’t all need to be treated.
Little scientific research on clinical
mastitis treatment efficacy.
My approach to clinical mastitis…….
Step 1




What is the severity?
If really sick, get treatment started
If mild, hold treatment pending
cultures
If moderate, culture and observe
Step 2




Get a milk sample
Submit for culture
Collect prior to therapy
Culture results
– Change treatment?
– Where’s the problem?
– Control measures???
– Culling decisions
Step 3: Treatment
“No results from a controlled trial are
available on the efficacy (i.e.
bacteriological and clinical cure) of
parenteral or intramammary
antibiotherapy.” (In a 2003 Review
article written for Veterinary Research
by Bergonier)
Step 3: Treatment

Mild cases
– Culture
– treat based on culture results
Step 3: Treatment

Moderate cases
– Culture
– Treat +/– Alter treatment based on culture results
Step 3: Treatment



Severe cases
Culture
FANO
– F = fluids
– A = antibiotics
– N = nonsteroidal antiinflammatories
– O = other
Step 3: Treatment: Fluids



Probably the most essential treatment
Help protect against toxins and
dehydration
Best route of fluid administration
– Oral (if rumen still working good)
– IV (if rumen shut down)

Consider fluid need on a daily basis
Step 3: Treatment:
Antibiotics





If severe, systemic antibiotics necessary
Should be broad-spectrum (example
oxytetracycline)
Goats not on the label
Treat systemically for 3-5 days
What to use intramammary????
– If blue bag (S. aureus) suspected, use a penicillin-like
intramammary product.
– If S. aureus not suspected and the doe is really ill, use
Spectramast® (Intramammary ceftiofur)


As coliforms die, endotoxin will be released.
Thus anti-inflammatory drugs must be on-board
Step 3: Treatment: Antiinflammatory




Do they help? Maybe
A field evaluation of Banamine for treatment
of naturally occurring acute caprine mastitis
found that treated does had a significantly
more rapid reduction of clinical signs than
controls.
Don’t give without considering fluids
Really should use if coliform mastitis
Step 3: Treatment: Other

NON-ANTIBIOTIC MASTITIS TREATMENT
CURE LACTATING COWS IN 2 DAYS of 3-4
Infusions
Now, VET HON provides you a natural medicine of
MASFRIGAO which is natural, plants, free from
antibiotic residues.
It has proven effective cure rates more than 95%
of the mastitis-causing bacteria after 3-4 infusions
(sure be recovered in 2 days).
Now MASFRIGAO is popular used in dairy herds
owing to nobody wants to drink antibiotic residues
milk & don't wants to dumping milk to the drain.
Some things seem logical but it
helps to take a step back and
consider...
