The greatest problems I have seen with dips have been application errors, improper storage and the use of the wrong dip for the job intended. Each procedure is designed to attack and kill a certain class of mastitis bacteria. Simply diluting a more concentrated dip cannot duplicate this process. I ncomplete dipping is another common problem. Spraying with hand bottles or vacuum-operated systems rarely ensures total coverage of the teat.
Partial application can lead to both environmental and contagious mastitis problems.
When the Teat is only partially dipped, you can only expect partial success in controlling mastitis. T hese spray systems can be convenient to use, but they may not always ensure total coverage of the teat surface. Before you change methods, make sure your employees are using equipment properly. T here can also be application problems when dip cups are used. If the well of the cup is not deep enough to fully submerge the teat, then mastitis problems can occur.
