As liners age they begin to stretch and lose tension, compromising their ability to properly massage the teat and maintain the blood supply.

Excessively worn liners tend to result in:

• Increased milking times
• Increased amounts of milk left in the udder
• Increased risk of teat end damage
• Increased risk of cup slips and falls
• Increased risk of spread of mastitis bacteria

This deterioration is a gradual but steady process which results in a progressive increase in the risk of mastitis - you may not even notice the early changes, but the mastitis risk is steadily increasing.

If you do change your liners and you notice a difference in milking performance, then the old liners were definitely in for too long - and the mastitis risk is likely to have increased significantly.

A key element of the Dairy Focus Mastitis Control System is the Dairy Focus Mastitis Diary which ensures all mastitis related activities, inlcuding liner changes, occur on time every time.
