title: Evaluation of linear dodecyl benzene sulfonic acid as a teat dip in a commercial dairy.
abstract: A postmilking teat dip containing 1.94% linear dodecyl benzene sulfonic acid was evaluated for approximately 6 mo on a commercial dairy farm that milked an average of 75 cows. Sixteen Staphylococcus aureus infections were diagnosed, 12 in the undipped control quarters and 4 in the dipped. Incidence of intramammary infection with Staphylococcus aureus was reduced 68.1%. Seventy-five infections were diagnosed as micrococci, 42 in control and 33 in the dipped group, a 23.6% reduction. A total of 37 Corynebacterium sp. infections were diagnosed, 21 and 16 in control and dipped groups, a 25.8% reduction. Teat skin condition did not change during the study.
