Teat Dipping: Is Fundamental to Milk Quality


During the 1960’s researchers in the United Kingdom investigated and reported what became known as the first comprehensive plan to control mastitis. This mastitis control plan has been successful since being introduced and is based on the notion that the infection rate of mastitis is directly related to the number of bacteria present on teat skin when the unit is attached to a cow. Teat disinfection is the basis of a mastitis control plan.
The main function of any teat dip is to flush off the milk film that is left on the teats wherever they were exposed to vacuum during milking. Failure to flush off the milk film will result in a nearly perfect food for bacteria to grow on the teat skin before the cows are milked at the next milking. Once the milk film has been flushed off, the teat dip leaves a disinfectant on the skin of the teat to kill any current bacteria. Teat disinfection does not affect existing infections.

Complete Coverage
While it is recommended to cover the teat end and bottom one-third of the teat barrel, this is insufficient. The teat should be completely covered with teat dip. Although teat dip can be sprayed onto teats with a teat sprayer, in most cases, the teat coverage will not be sufficient and uses significantly more solution than proper dipping. The most common failure in most teat dipping/ spraying programs is not adequately covering teats with a good quality germicidal teat dip immediately after milking.
Because the role of teat dipping is to avoid bacteria colonization on the teat skin as well as the teat canal, it is critical to regularly and correctly cover the entire area of the teat that had contact with the milking unit. Teat dip coverage should be checked on a regular basis

The typical use rates for various application methods are as follows: spraying approximately 20 ml per cow, non-return dipper 6 ml to 8 ml, foaming 4 ml to 6 ml.

Think about storage and contaminating the teat dip, leaving lids off containers allowing air to possibly enter the container may have an adverse effect on your solution.
