  1. MASTITIS CONTROL, PREVENTION, AND TREATMENT IN GOATS Leo Timms Iowa State University Dairy Science Extension

  2. GOAT MASTITIS • Basic mastitis facts • Mastitis detection • Mastitis control • Prevention • Treatment

  3. $$$$$$$$$$$$$$$$$$$$$ • Occurs in every herd • Decreased doe performance (milk) • Milk discard costs • Doe/ kid mortality and morbidity • Doe replacement costs • Labor costs • Veterinary costs • Feed costs (orphans)

  8. MASTITIS • Inflammation of the mammary gland where inflammation is the reaction to tissue injury • Redness • Swelling • Heat • Pain • Loss of function • 99% of inflammation results from infection

  9. TYPES OF MASTITIS • Clinical: visual abnormalities (milk/udder/doe) • - fever - loss of appetite - depression - death • Chronic: - long duration - variable signs • - contagious? - fibrosis (nodules): udder palpation • Subclinical: * No visible signs *Special tests * Loss of function • Mastitis types are correlated to organisms!!!

  10. KIDDING WEANING ?

  11. Inflammation: part of innate immunity BSA, Ig Nagase Na,Cl

  12. HOW DO WE FIND IT IN MY HERD?

  13. MASTITIS DIAGNOSTICS “How do I look for (find mastitis)?” • Clinical : • -Milk - udder - systemic • Udder Palpation • Subclinical • * Cultures: Know your organisms • * SCC: CMT / Electronic

  14. UDDER PALPATION

  15. < 5% with clinical mastitis • Take a sample for culture

  16. KNOW YOUR ENEMY (germ warfare)

  17. Mastitis:Detection and Interpretation April 15, 2004 April Boll

  18. Mastitis Organisms • Contagious • Spreads cow-to-cow • Fomites – milker’s hands, equipment • Survive poorly in environment • Enviromental • Found in feces, soil, bedding, etc. • Cannot eliminate source of infection

  19. Contagious Organisms Streptococcus agalactiae: Infected Cows Milking Time Subclinical / Chronic Very High, little self cure Easy, most abx work -Organism- -Source- -Spread- -Status- -Immune Cells- -Treatment- Staphylococcus aureus: Infected Cows / Wounds & Cuts Milking Time Subclinical / Chronic High, little self cure Difficult, resistance & abcesses

  20. Contagious Organisms Respiratory Tract Blood Mycoplasma Initially from the lungs; then from infected cows Milking Time Clinical / Acute Medium High, some self cure No treatment / vaccine, Cull & hope for self cure Organism- Source- Spread- Status- Immune Cells- Treatment-

  21. Environmental Organisms Environmental Streps: Environment Environment Clinical / Acute (few chronic) High, Self cure daily Usually effective, chronics hard -Organism- -Source- -Spread- -Status- -Immune Cells- -Treatment- Coliforms, E. coli & Klebsiella: Environment Environment Clinical / Acute High, Easily killed by WBC

  22. Opportunistic / Environmental Organisms Skin Staphs Skin Skin May be chronic Low, 50% self cure Very susceptible to abx Organism- Source- Spread- Status- Immune Cells- Treatment-
