Summary and Implications
Thirty new experimental persistent barrier type teat dips and one commercial dip for dry cow mastitis control were evaluated for adherence persistency on teat ends of late gestation cows and heifers (1-2 weeks pre-calving). There was tremendous variability both within and across prototype dips, and all products failed to have a high percentage of teats protected at 3 and 5 days post dipping. Stronghold (Alfa-Laval, Inc) showed high percentages of protection (100 and 65%) at 3 and 5 days post dipping. Other issues with prototype dips included viscosity, visibility, and odor.
