THE 5-POINT PLAN Mastitis prevention programme

The 5 Point Plan 1. Teat disinfection - after every milking 2. Antibiotic drying off - dry cow therapy 3. Prompt antibiotic therapy -clinical cases 4. Culling cows - with repeated cases 5. Milking machine maintenance

1. Post milking teat disinfection  Chose an effective product  Apply by dipping using a dip cup  or by spraying  ensure that every teat is covered  keep cows standing for at least 30 minutes after milking

Choose an effective teat dip  Products in use in Europe  Iodophors  Chlorhexidine  Chlorine dioxide  Lactic acid  emollients ;Glycerol/Sorbitol  Authorisation  Veterinary medicines  Registered disinfectants  Activity testing  Use of standard methods  BSEN 1656

Practice good hygiene during milking  1)Wear clean apron, overalls.  Wear gloves, change at regular intervals or if damaged. If gloves not worn wash hands or use handrub disinfectant at regular intervals and especially after milking infected animals.  2)Milk infected cows last  Keep infected milk or milk from antibiotic treated cows out of bulk tank  3)Wash clusters  particularly after falling on the floor during milking and disinfect with suitable general purpose disinfectant before using on the next animal  4)Administering antibiotic tubes  wash hands thoroughly and wear fresh gloves.  Clean teat ends, furthest two teats cleaned first. Teats must be allowed to dry before tubing.  Tube in the opposite order to cleaning ie. nearest teats first.  Dip teats with teat dip and ensure that cows are standing for at least 30 minutes after tubing.

2. Dry Cow Therapy  Abrupt drying off recommended  All quarters must be treated  Teat ends cleaned with surgical spirit  2 teats furthest away first and then 2 closest  ensure teats are clean and dry  Treat with antibiotic  2 teats nearest first and then 2 furthest away  Dip teats with teat dip  leave standing for at least 30 minutes

3. Prompt Antibiotic Therapy  Early detection  Appropriate therapy  Recording of all clinical cases  records of antibiotics used

4. Culling  Cull persistent offenders  repeated cases of clinical mastitis  3 cases in one quarter in one lactation  or 5 cases in mixed quarters in one lactation

5. Milking Machine Maintenance  Service regularly  static test twice a year  dynamic test yearly  Frequent checks  inspect teats immediately after milking unit removed  inspect liners and replace any damaged liners  change liners every 2,500 milkings  check circulation cleaning products and procedures

Milking Machine and Mastitis  Milking machine problems can increase the rate of new infections  worn liners harbour bacteria  liner slip causes teat end impacts  teat end damage caused by too high vacuum levels, defective pulsation

Environmental hygiene  Housing - regular change of bedding/mucking out, cubicle mats, dry straw, sand for bedding  Walkways kept clean and dry as possible, automatic scrappers  Teat preparation before milking, pre-dipping

Progress in Mastitis Control in the UK  75% reduction in the rate of clinical mastitis  Still 1,000,000 cases of clinical mastitis per year in a herd of 2,500,000 cows  Development of vaccines and further attention to detail may reduce number of cases to 500,000 per year

Evans Vanodine Best Practice Dairy Hygiene Programme  Based on internationally recognised principles  supported by quality products  manufactured at our licensed premises  under strict quality control procedures - ISO 9002  with microbiology support - UKAS Testing Laboratory 1108

STAGE 1- Preparation  Keep holding areas as clean as possible - free of dung, dirty water etc.  Clean teats and udders with medicated wipe or disposable paper towel  Fore milk  Pre-dip with an approved Iodine based dip  Dry wipe

STAGE 2 - Milking

 Wear clean apron, overalls  Wear gloves, change at regular intervals or if damaged. If gloves not worn wash hands or use handrub disinfectant HANDSAN at regular intervals and especially after milking infected animals.  Milk infected cows last  Keep infected milk or milk from antibiotic treated cows out of bulk tank  Wash clusters  particularly after falling on the floor during milking and disinfect with FAM 30 at 1:200 before using on a new animal

STAGE 2 - Milking  Administering antibiotic tubes  wash hands thoroughly and wear fresh gloves.  Clean teat ends with medicated wipes, furthest two teats cleaned first. Teats must be allowed to dry before tubing.  Tube in the opposite order to cleaning ie. nearest teats first.  Dip teats with teat dip and ensure that cows are standing for at least 30 minutes after tubing.

STAGE 3 - Teat dipping/spraying  Immediately after milking,  dip or spray the full length of each teat  ensure the entire surface of the teat is covered  treat damaged or sore teats with udder salve, cream or ointment  After milking  keep cows standing for 30 minutes  empty and wash teat dip cups

STAGE 4 - Circulation cleaning  Pre-rinse  clean warm (38-44°C) water  8-10 litres per unit  run to waste  Outside of equipment  Wash with warm water and detergent.  Check for damaged or worn components and replace.  Soak filters in filter cleaner

STAGE 4 - Circulation cleaning (continued)  Hot rinse  Hot water (>80°C)  4 litres per unit or until discharged water is at least 50°C  Circulation cleaner  Prepare in hot (at least 80°C) water  Draw into the plant until discharged water is at least 50°C  Allow to circulate for 10 to 15 minutes before discharging to waste  Rinse thoroughly with clean water, dairy hypochlorite may be added to the final rinse  Milkstone remover

STAGE 5 - Bulk Tank Manual Sanitising  Immediately after tank has been emptied rinse with cold water  Place plug and dip-stick in bulk tank sanitiser and scrub clean. Rinse with clean cold water and allow to dry  Brush all interior surfaces with tank sanitiser allow 2 minutes contact time  Allow the solution to collect in the outlet and brush while running to waste.  Hose down the tank and lids with cold water and allow to drain.

STAGE 5 - Bulk Tank In-Place Sanitising  Immediately after tank has been emptied rinse with cold water  Circulate prepared solution of bulk tank sanitiser for 15 to 20 minutes in the tank  Run to waste  Rinse with clean cold water and allow to drain

STAGE 6 - Cleaning and disinfecting animal housing  Cubicle bedding  Muck out and change regularly  Disinfection  Use FAM 30 diluted 1:180 for walkways, milking parlour, calving pens, floors and stalls  Foot and wheel baths  filled with FAM 30, clean out and re-fill regularly

BIOSECURITY Buy animals from disease free stock with low cell counts Milk new or infected cows last Restrict access, use foot and wheel dips Provide clean protective clothing for herdsman and visitors
