Summary and Implications

Mastitis research has shown 40-50% of intramammary infections (IMI) are contracted during the dry or non-lactating period with greatest percentages occurring during first and last two weeks of dry period. The ability to develop and apply external persistent barrier teat dip products (like a liquid bandage) that can persist for these 1 week periods could decrease IMI, thus improving animal health and performance, and product quality and safety. Objective of this study was to evaluate an experimental vs. commercial persistent barrier dry cow teat sealant dip with particular interest and comparisons of dip persistency in providing teat end protection, and overall teat end and skin health.

Two external teat sealants were applied to 30 animals in a half udder designed trial for assessment of adherence to teat skin/teat end over a period of 5 days. On average, the control product had 62% teat ends protected 3d after application, while it was 25% for the experimental product 549-60-1. It is concluded that the experimental product did not meet the expected efficacy results
