title: Evaluation of spray application of postmilking teat sanitizer.
abstract: Application of postmilking teat sanitizer by spraying was evaluated in two experimental challenge trials with Streptococcus agalactiae (ATCC 27956) (McDonald 44). A .5% quaternary ammonium teat sanitizer was used in both studies. By direct comparison, teat spraying and dipping did not differ in effectiveness. Efficacy for the .5% quaternary ammonium compound was 58.6%, similar to results on the product applied as a dip (13).
