The benefits of correct cup attachment include:
- Increased milking efficiency.
- Reduced milker fatigue and injury.
- Improved cow behaviour - cows will be calmer and more acceptant of the clusters.
Attachment of clusters is given surprisingly little attention considering it has a major role in the milking routine.
Most milkers develop their own method without any direction. This can lead to poor cupping techniques and issues with repetitive strain injury. The aim is to find ways to change clusters consistently and reliably without unnecessary physical strain and avoiding the problems of muscle/tendon over-use.
Cupping techniques
Two cupping techniques are explained here and switching between methods during milking is recommended to relieve muscle strain. Each method works on rotaries or herringbones, although there are some refinements depending on the dairy type.
Round-the-circle method
This method is (or should be) taught to all new milkers as a simple, easy to learn, reasonably quick method that avoids problems. It is not the fastest method but it is reliable and easier on the milker because there is much less chance of getting kicked.
Two-at-a-time method
For a rest try putting on the two front cups more or less at once, then the back right, then the back left with the other hand.
Cluster alignment
Once the clusters are attached, check the cluster alignment with the udder. The clusters should sit squarely under the udder. In herringbones where the clusters are attached from between the back legs, the long milk tube and pulse rubber should be in line with the cow’s backbone. Many new dairies, both rotary and herringbone, come with cluster alignment components.
Three titters
Rather than twisting the short milk tube, use a cup plug and leave the unused cup hanging – this reduces pressure on the claw.
Use the cup intended for the ‘unmilked’ teat on the opposite teat e.g. if the back left teat is not milked, put the back left cup on the back right teat. This aligns the cluster better for milking.
