MASTITIS CONTROL, PREVENTION, AND TREATMENT IN
GOATS

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)

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!!!

HOW DO WE FIND IT IN MY HERD?

MASTITIS DIAGNOSTICS
How do I look for (find mastitis)?

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

Mastitis Organisms

• Contagious
• Spreads cow-to-cow
• Fomites milkers hands, equipment
• Survive poorly in environment
• Enviromental
• Found in feces, soil, bedding, etc.
• Cannot eliminate source of infection

27
Contagious Organisms
Streptococcus agalactiae Infected Cows Milking
Time Subclinical / Chronic Very High, little self
cure Easy, most abx work
Staphylococcus aureus Infected Cows / Wounds
Cuts Milking Time Subclinical / Chronic High,
little self cure Difficult, resistance abcesses
