PRE teat skin swab sample before teat disinfectant application, POST teat skin swab sample after teat disinfectant application
Product: 1 = Lacto-cel, 2 = Duogold, 3 = Arkshield, 4 = Super Cow Teat Foam, 5 = Sensodip 50, 6 = PureChem Chlorhexidine, 7 = Kenomix, 8 = Lanodip Pre-Post, 9 = Hypred Quick Spray, 10 = Maxidine RTU. The log reduction means of staphylococcal, streptococcal and coliform isolates with different letters are statistically significant (P < 0.05)
