1. Bovine Mastitis

2. Normal udder

3. Vascularisation of udder

4. Mastitis-inflammed udder

5. What are Milk quarters? Made of 4 independent glands
Interconnected by blood supply
Milk does not pass from 1 quarter to other
4 quarter
Fore and Hind quarter

7. What is mastitis
The most costly disease affecting dairy cattle throughout cattle.
Inflammation of 1 or more than 1quarter of udder.
Inflamed- swelling, pain, warm, redness, heat

8. Economic impact of mastitis
Milk discarded due to medication , presence of bacteria, white blood cells
Decreased milk production
Bacteria, blood cells, enzymes
Decreasing lactose, casein and fat production
Increase in SCC.

9. What are health concerns of mastitis
Animal health
Loss of functional quarter
Lowered milk production
Death of cow
Human health
Poor quality milk
Antibiotic residues in milk

10. Subclinical mastitis Udder appears normal Milk appears normal
Elevated somatic cell count
Lowered milk output
Long duration

11. Clinical mastitis 5-10% of all mastitis cases Severe and moderate
Includes systemic involvement
Acute and chronic
Acute- severe type of mastitis
Loss of appetite
Depression
Clots/flakes of blood are present
Chronic type- fibrosis, atrophy of mammary gland

12. What causes of mastitis
Bacteria-70%,streptococci, staphylococci, coliform, E.coli,M.bovis
S.aureus, s. agalactiae, c.bovis
Yeast and molds-2%
Unknown- 28%
Physical
Trauma
Weather extremes
Contaminated teat dips, skin lesion, mud hole,flies

13. Where do these organisms come from
Infected udder
Environment
Bedding
Soil
Water
Manure
Replacement animals

14. Sitting posture of cow

15. Milking machine for cattle

19. Diagnosis -California mastitis test CMT
Milk from uninfected cow has less than 2,00000 scc/ml.
A detergent based test
Composed of alkyl aryl sulfonate
Sodium hydroxide
Bromocresol purple
Scoring of milk samples
Grade 1, 2,3
Alternatively surf test

21. CMT

22. Milk paddle

23. Treatment Intrammary infusion Bovaclox-cloxacillin
Cefasafe-cephapirine benzathine
Spectrazole- cefuroxime
Cepravine-cephalonium
Oxytetracycline 11mg/kg B.w

24. Intrammary infusion

25. Control of mastitis Milking machine maintenance Teat dipping
Early treatment of clinical cases
Culling cows with chronic mastitis
Vascularisation of udder
