The rate of new udder infection is related to the number of mastitis-causing pathogens on teat ends. Using a post dip directly after unit removal will kill pathogens this then reduces the chance of those pathogens getting into the udder.
Post milking teat disinfection is especially effective against the contagious pathogens Staphylococcus aureus and Streptococcus agalactiae. While milking can spread any type of mastitis pathogen, these two pathogens in particular spread from cow to cow during the milking process. Post milking teat disinfection is less effective in reducing the new infection rate of “environmental” pathogens such as coliforms and Streptococcus species other than Streptococcus agalactiae. Control of environmental pathogens requires management practices including maintaining cows in a clean, dry environment; good premilking hygiene, including premilking teat disinfection and thoroughly drying teats; and using functionally adequate milking machines. Milkers should continue post milking teat disinfecting as a routine part of milking procedures, even if Streptococcus agalactiae has been eliminated and somatic cell counts are low.
Latest research has shown 50% of new udder infections can be prevented by disinfecting teats with an effective product immediately after every milking. Teat disinfection DOES NOT affect existing infections. Existing infections are best eliminated by dry cow treatment and culling chronically infected cows. Prevention of new infections by teat disinfection and elimination of existing mastitis cases reduce the level of mastitis in a dairy herd year by year. Improvements, such as decreased cases of clinical mastitis and/or lowered herd somatic cell counts, generally can be observed within a few months. Do not expect a magic wand to resolve any ongoing issues it takes hard work and determination and time!
Post milking teat disinfectants can be applied either by dipping or spraying. Either method is acceptable, if done in a manner that thoroughly covers the entire teat. Care should be taken to ensure that all four teats are covered. The disinfectant should be applied immediately after every milking.
Store all disinfectants in cool, dry areas. Do not allow disinfectants to freeze! Keep containers closed to prevent contamination, do not use after the expiration date. Do not adopt a mind-set that teat disinfectants will kill all pathogens. They don’t?
Follow label instructions for use. Use teat disinfectants at the recommended concentration. Do not dilute unless indicated on the label. If dilution is necessary, be sure that water quality standards (bacteria, pH, hardness, etc.) are met. Use a clean container for diluting, and thoroughly mix the final product.
Disinfectant cups should be emptied and cleaned as part of the routine wash-up after each milking or if they become contaminated during milking. Never pour used disinfectant back into the original container.
Good teat disinfectants should have efficacy against the major mastitis pathogens, be economical, easy to apply, and should maintain or promote good skin condition. Both traditional and barrier types of disinfectants are available. Whatever type is chosen, the product should have documented efficacy against all the major contagious mastitis pathogens, insist on the supplier providing this information, saying it kills pathogens in 15 seconds is utter nonsense , what is this claim based on ? don’t fool yourself in believing these adverts .
Dairy farmers should demand information from the manufacturer on compliance regulations and results of controlled research studies showing efficacy. A lot of labelling is very sparse and uninformative, for example some labels should state they dry skin,
It is important to educate yourself about the products that you are considering. They should inquire as to the types of studies that have been conducted, the pathogens that the product is designed to control, and the efficacy results.
What affect these dips have with dry chapped skin , how affective is the teat disinfectant when in contact with excessive lime on beds , think before you buy .
More than 50% of new udder infections can be prevented with proper teat disinfection.
Apply teat disinfectant immediately after milking.
Ensure that disinfectant thoroughly covers the entire surface of all teats.
Handle teat disinfectants properly.
Demand information and educate yourself about the teat disinfectant that you plan to use.
Teat disinfecting is an important part of a mastitis control plan. In addition to disinfecting teats immediately after milking, using good milking and environmental management procedures, using properly functioning milking equipment, treating every quarter of every cow at dry off, identifying and treating or managing clinical cases promptly, and culling chronically infected cows should provide an effective mastitis control plan for your dairy.
