This year's Dairy Event will see a useful addition to the already extensive range of dairy liners and tubing offered by Milk-Rite. The IP-V European Impulse is the first ever mouthpiece-vented triangular liner and shell combination to be launched for use by dairy farmers. The unique combination of triangular liner and shell is said to improve milk extraction and udder/teat health, reduce cross contamination, maintain milk quality and provide added comfort for cows and operators.
Air has to be introduced into the milking system to allow the milk to move – this normally comes in through a vent in the claw. Venting a liner at the mouthpiece is a more effective way of moving the milk away from the teat, since the air is introduced above the teat-end. In addition to improving milk flow away from the udder, this vent positioning also reduces milk turbulence in the liner and backflow from the claw. (See diagram)
Backflow of milk is not desirable, since it allows milk and bacteria from one teat to come into contact with the other teats on the same cow or other cows. Backflow increases the risk of cross-infection and creates turbulence.
Milk turbulence is similar to the churning process which affects its chemical composition. Disrupting the milk fat globules during turbulence results in partial lipolysis. Acids released during the lipolysis of milk have the strong flavours and odours of carboxylic acid, which have the potential to taint milk.
Operator stress is less with the IP-V due to a reduction in the overall weight of the milking cluster. Cow comfort is increased due to the more controlled vacuum drop through the system, and it allows a more rapid and easier cluster removal at the end of the milking process.
The IP-V European Impulse features a Milk-Rite mouthpiece vented triangular liner inside a triangular-inner-profiled heavy duty plastic shell. It is available in a range of different sizes to fit most types and makes of parlour.
