Case Study: Use of a Glycolic Acid Based Barrier Teat Disinfectant During Winter Did Not Adversely Affect Teat Condition

摘要

For some dairy producers in the USA, it is common practice to switch the use of their usual post-milking teat disinfectants to winter-type products or powdered dips when ambient temperature drops below 0°C in the winter season. Previously it was demonstrated that an aqueous teat disinfectant performed better than a powder product with regards to teat skin and teat end condition when used during the winter period (Lopez Benavides et al, 2011). The use of barrier-type products during winter is less documented and merits investigation. Results of this study are associated with the use of a glycolic acid-based post-milking barrier teat disinfectant, OceanBlu~(TM) Barrier (OB; GlyTec~(TM) and 10% emollients; DeLaval) during the winter period. GlyTec~(TM) is a proprietary blend of glycolic acid and other ingredients (inc. 3% glycolic acid).
