title: Efficacy of a Fatty Acid-Lactic Acid Postmilking Teat Germicide in Reducing Incidence of Bovine Mastitis.
abstract: The efficacy of a postmilking teat germicide containing Lauricidin®, and caprylic, capric, and lactic acids was evaluated against new udder infections caused by Staphylococcus aureus and Streptococcus agalactiae . The germicide was evaluated in two controlled infection trials using two dilutions of a concentrate. Active ingredients of the concentrate were 1% Lauricidin®, 5% caprylic/capric acids, and 6% lactic acid. The first dilution contained one part germicide to seven parts distilled water. New intramammary infections with Staphylococcus aureus and Streptococcus agalactiae were reduced 34.6% (P < 0.10) and 63.1% (P < 0.01), respectively. In the second trial, the germicide was diluted one part concentrate to three parts distilled water and tested using the same protocol. Efficacies were 67.8% (P < 0.001) and 77.2% (P < 0.001) against Staphylococcus aureus and Streptococcus agalactiae , respectively.
