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. When mixing concentrated dips, make sure you use good water. Water high in total dissolved solids may have to be treated before use. Be aware of storage conditions. Do not let teat dips freeze, since freezing can render some dips ineffective.
