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)
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 protein % same
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!!!

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
April 15, 2004 April Boll
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 -Organism- -Source- -Spread- -Status- -Immune Cells- -Treatment- Coliforms, E. coli & Klebsiella: Environment Clinical / Acute High, Easily killed by WBC
30
Opportunistic / Environmental Organisms
Source- Spread- Status- Immune Cells- Treatment- Skin Staphs Skin May be chronic Low, 50% self cure Very susceptible to abx
