Benefits
Changing your milking liners every 2500 milkings will provide you with the following benefits.
Shorter milking time - Milking times tend to increase during the season to a peak around November when maximum yield is achieved, changing liners provides a quicker milk-out, less energy is used in the plant and there is less stress on cows & more time for them to be feeding.
Reduced cup-slip - The causes of cup-slip are varied & not always the fault of milking liners, however worn liners can significantly contribute to slippage. Less cup-slip can lead to savings in animal health costs (less teat / udder-health issues), energy savings from shorter milking times & less stress on cows.
Lower somatic cell count - Changing your liners during peak SCC times (after calving & toward the end of lactation) may assist in reducing your SCC. General teat & udder health may be also improved. New rubberware (with less cracks) means less risk of bacteria entering the milk that can cause potential grading.
Increased yield - The volume / weight of milk solids harvested from cows will increase through more complete milking-out of cow's udders & also quicker average milking time, this allows the cows more time to feed and to produce more milk.
