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)

4. MASTITIS % infected patho % infected
species giving birth genecity wean/dry
Dairy cow
Beef
Goats (W)- 70 M
Sheep
Pigs %
Horse ?
Human higher
than Birth

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

6. Alpha-lactalbumin
lactose
NaCl
BSA Ig
Nagase ?

7. Fat % same
Poor membrane
More rancidity
Plasmin
Casein

8. 99% of inflammation results from infection
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. WEANING
KIDDING ?

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

13. HOW DO WE
FIND IT IN MY
HERD?

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

19. UDDER PALPATION

20. < 5% with clinical mastitis
Take a sample for culture

24. KNOW
YOUR
ENEMY
(germ warfare)

25. Mastitis: Detection and Interpretation

26. Mastitis Organisms Contagious Enviromental 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

27. 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

28. Contagious Organisms Respiratory Tract Blood Organism- Mycoplasma
Source-
Spread-
Status-
Immune Cells-
Treatment-
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

29. Environmental Organisms
Environmental Streps:
Environment
Clinical / Acute (few chronic)
High, Self cure daily
Usually effective, chronics hard

Coliforms, E. coli & Klebsiella:
Environment
Clinical / Acute
High, Easily killed by WBC

30. Opportunistic / Environmental Organisms

Skin Staphs

May be chronic
Low, 50% self cure
Very susceptible to abx
