goat mastitis
GOAT MASTITIS
  • Basic mastitis facts
  • Mastitis detection
  • Mastitis control
  • Prevention
  • Treatment

$$$$$$$$$$$$$$$$$$$$$
  • 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)

mastitis1
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
types of mastitis
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!!!

mastitis diagnostics
MASTITIS DIAGNOSTICS

“How do I look for (find mastitis)?”

  • Clinical :
  • -Milk - udder - systemic
  • Udder Palpation
  • Subclinical
  • * Cultures: Know your organisms
  • * SCC: CMT / Electronic

< 5% with clinical mastitis

  • Take a sample for culture

mastitis organisms
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
contagious organisms
Contagious Organisms

Streptococcus agalactiae:

Infected Cows

Milking Time

Subclinical / Chronic

Very High, little self cure

Easy, most abx work

-Immune Cells-

-Treatment-

Staphylococcus aureus:

Infected Cows / Wounds & Cuts

Milking Time

Subclinical / Chronic

High, little self cure

Difficult, resistance & abcesses

contagious organisms1
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
