Mastitis Control/SCC Control Don Crowley B.Agr.Sc Tom Weldon B.Agr.Sc Joint Program with Dairygold Co-op. On-Farm Investigation Recommendations to Tackle problem.

Teagasc Dairygold Joint Programme on Milk Quality Don Crowley, Tom Weldon & Ger McMahon Goals: Reduce SCC & Mastitis Method: Visit farm at milking.(800 farms visited) Analyse Records, Equipment and Practices Recommendations made. Usually 1 follow up call

Results (SCC) of Farms Visited ’07 vs’08 24% 11% 27% 13%

Typical scenarios Scenario 1: A high cell count on a farm, but no cases of mastitis, using no tubes !!! Scenario 2: A farm with a low cell count, getting a lot of cases of Clinical mastitis and using a lot of tubes. Scenario 3: High incidence of E.coli mastitis.

Recent survey results: 65% of clinical mastitis cases occurring in the first 5 Days of Lactation. 5% in the second 5 days. 30% in the remainder of lactation. Prevention is time well spent.

Mastitis 2 Categories of Bacteria Contagious Bacteria: –Staph Aureus –Strep Agalactiae Environmental Bacteria: –E. Coli –Strep Uberus

Approach to Mastitis Problem Assess the present situation Farm Visit (at milking) Costs: Co-op fines, tubes, treatments, vet bills, milk lost, cull rates Labour, frustration Analysis of records(not always available)

Case Study - SCC Farmer A 14 Unit parlour, no ACR ’ s, 100 cows (30 Aut, 70 Spring) 1700 Gallon average, 23% Replacement rate

Case Study Observations & Recommendations Milking practices observed: Cow teats scored for damage i.e. odema, congestion Hyperkeratosis 50% > score of 4 Cow comfort and stress e.g. electrical issues measured Milking machine tested

Case Study -Teat End Damage

Case Study Recommendations/Goals Stop over milking (Teat end damage). Stop spread of infection. Pre-spray & dry wipe, Disinfect clusters(between each cow) for 2 wks. Wear gloves Post spray all cows.

Case Study - Financial Reward Bonus=€ 3, Additional milk sales=€ 4, Reduced Vet and tube=€ 1, cows not culled =€ 2, Reward=€11, pa

Main Mastitis Causes: Main cause Milking machine =33% Milking practices =33% Infection Control/Hygiene =33%
