Rubber Milking Liners

Rubber Milking Liners Play a Substantial Role in the Dairy Industry

You can’t minimize the importance of the milking liner. After all, it’s the only part of the milking machine that comes into direct contact with the cow’s teats. That alone is enough to make it a vital component in the process of milking cows swiftly, gently and thoroughly.

To save money, however, some in the dairy industry are using their inflation liners a few weeks or months past their recommended life. While this might seem like a smart and economical idea, in reality, it is usually costly.

Teat cup milking liners can deteriorate over time

When teat cup liners begin to age, their shape and surface condition can start to change. There are also detrimental effects on their milking features. Outdated milking liners can result in the following issues:

• The average time to milk each cow increases
• Liners slip more frequently
• More milk remains in the quarters of an udder when the cups are removed
• Teat-end problems become worse
• Cows can start behaving badly
• Coming off of the milking claw

Worsening teat-end condition and frequent liner slips can also increase the risk of mastitis. You’ll know you waited too long to change your liners if there is a noticeable improvement in milking performance after you replace them.

Replace the liners at regular intervals

As you can see, it can be a lot less expensive to change your liners before they wear out. And replacing all four liners in the cluster at the same time is the best way to ensure that the milking characteristics among the four teat cups remain similar.

Manufacturers usually recommend that rubber liners be replaced after between 2000 and 2500 milkings, and others add a maximum life of four to six months for them.

Keep in mind that the life of rubber milking liners can be influenced by many factors that include:

• The materials from which they are made
• How they are used, cleaned, and stored
• Their exposure to sun, heat, chemicals, and ozone

Rubber milking liners keep evolving

Although pure rubber milking liners work very well, they can break down over time, especially when exposed to sterilization cycles and high temperatures. New formulations are being developed, such as silicone liners, which have some added advantages.

These silicone liners allow farmers to see the milk leaving the cow and know when the cow is milked out. Silicone is more resistant to oxygen and ozone, which provides longer life to the milking liners. The new generation of liners has a stronger inner surface and is made to hold onto the fittings better, and they also absorb fewer milk fats and remain clear longer.

Remember, the properties of each type of milking liner can determine the characteristics of the milking process. In most cases, silicone liners will give a gentle milking, while the thicker rubber liners will likely provide a faster milking.
