Efficacy of dodecylaminoalkyl glycine teat dip against Staphylococcus aureus and Streptococcus agalactiae mastitis.

Dodecylaminoalkyl glycine teat dip, diluted to 1.5% active ingredients, was evaluated in a controlled experimental challenge study to determine efficacy for preventing new intramammary infections with Staphylococcus aureus (Newbould 305) and Streptococcus agalactiae (McDonald 44). The dip reduced the incidence of intramammary infection with Staphylococcus aureus by 81.2%. Reduction of Streptococcus agalactiae intramammary infection was 67.5%.
