    1. Caprine Mastitis: Management and Control Dr. Jerry Roberson UT College of Veterinary Medicine

    2. Definitions Mastitis: inflammation of mammary gland Mostly bacterial Mostly unseen inflammation

    3. Subclinical vs Clinical Mastitis Subclinical: you can’t see it. Clinical: you can see it.

    4. 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

    5. Chronic Mastitis Long duration Can be subclinical or clinical Primarily contagious pathogens

    6. THE BUGS

    7. 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)

    8. CNS 25 + speices of coagulase negative staphylococcus (CNS) Most common udder pathogens Minor pathogens????? Prevent other major infections? Live on body sites

    9. Major Environmental Pathogens Coliforms E. coli Klebsiella Pseudomonas Pasteurella Environmental Streps

    10. Coliforms: How are they transmitted? Enter via the teat canal Opportunist

    11. Mycoplasma Does not grow on routine bacterial culture (requires a special agar) Contagious No successful treatment May also be arthritis and ear nfections.

    12. CAE (Caprine Arthritis Encephalitis) A virus Cause Hard Bag May be no other signs No treatment Consider a control program

    13. Management of mastitis They don’t all need to be treated. Little scientific research on clinical mastitis treatment efficacy. My approach to clinical mastitis…….

    14. Step 1 What is the severity? If really sick, get treatment started If mild, hold treatment pending cultures If moderate, culture and observe

    15. 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

    16. 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)

    17. Step 3: Treatment Mild cases Culture treat based on culture results

    18. Step 3: Treatment Moderate cases Culture Treat +/- Alter treatment based on culture results

    19. Step 3: Treatment Severe cases Culture FANO F = fluids A = antibiotics N = nonsteroidal antiinflammatories O = other

    20. 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

    21. 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

    22. Step 3: Treatment: Anti-inflammatory 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

    23. Step 3: Treatment: Other Calcium Tons of other things

    24. New Cure-All Mastitis TX 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.

    26. Some things seem logical but it helps to take a step back and consider...
