Remove units promptly when milkflow decreases to a minimal rate. There are no data to support overmilking as a good or acceptable practice. Minimize Individual Teat Cup Removal Cows with significantly different levels of production between quarters should be culled. In those cases where an individual teat cup must be removed, use both hands. At the same time, use the other hand to release the teat cup assembly.
Extreme care is required in all cases.
Thus, it is probably a source of pathogens to infect other quarters through reverse droplet impacts that occur during erratic vacuum fluctuations. As a rule, no more than one teat cup should be removed on an individual basis per 10 cows milked. Removing units while the vacuum is still being applied causes extreme stress on the teat and extreme vacuum fluctuations, which increase the risk of new infections. Turn off the vacuum and wait three to five seconds while the vacuum in the claw is relieved through the vent. Dip Teats Immediately after unit removal, apply a commercially prepared teat dip with known effective antibacterial ingredients.
