Post-Milking Teat Disinfection

Post-milking teat disinfectants have been widely tested and used to prevent mastitis caused by contagious and environmental bacteria. The appropriate use of teat disinfecting products reduces mastitis rates and the need for antibiotic use. Post-milking teat disinfectants are based on a range of germicides, levels and types of emollients, and physical forms and are applied by a range of application methods. When recommending teat dip products, it is important to assess the udder health situation, as well as management of the milking process. Certain product types may provide benefits when used properly but will have increased risks when used under less than ideal conditions.

Post-milking teat disinfectants have been widely tested and used to prevent mastitis caused by contagious and environmental bacteria. The NMC has documented products that have been proven effective in peer-review publications.

The appropriate use of teat disinfecting products reduces mastitis rates and the need for antibiotic use. Post-milking teat disinfectants are based on a range of germicides, levels and types of emollients, and physical forms and are applied by a range of application methods. Historically, products were applied by dipping or spraying.

In most published studies, products were applied by dipping. Today products are marketed in a variety of physical forms and application techniques, without always a clear understanding of the advantages of the different product types. These types include: dippable, sprayable, high viscosity, barrier / film-forming products, foam products, dry powders, winter dips, and concentrates.

Physical properties of the various product types are described in Table 1. The major property difference is the viscosity, which dictates if the product can be dipped or sprayed. Disinfectant application via dipping is widely preferred because it is easier to insure adequate teat coverage. High viscosity products require dipping, which results in an improved procedure.

Teat dip product types can also be described based on the perceived benefits, typical use conditions, and potential risk factors. When recommending teat dip products, it is important to assess the udder health situation, as well as management of the milking process. Certain product types may provide benefits when used properly but will have increased risks when used under less than ideal conditions. For example, barrier teat dips have the potential benefit of improved teat protection during the inter-milking period; however, good pre-milking teat cleaning is required to insure that all product and soil is adequately removed from the teat. These products would not be recommended if no teat cleaning is done or if only a dry udder towel is used.

 

Summary

• Teat disinfectants are marketed in a broad range of types and physical forms.

• Each form provides a range of benefits and also risk factors relating to optimum benefit.

• Advisors should be aware of the benefits and risks, when assessing udder health improvement programs and must match the product with the management practices on the farm.
