Painful Cow Milking
The following videos show that cows are not happy with their milking experience with conventional milking machines. This is a direct result of the physical abuse induced by those products as they fail to provide relief from the vacuum of the milking process. Those products simply pinch the teat ends during the "rest" phase doing little more than simply forcing bacteria up the teat canal to cause a bacterial infection that can also lead to more pain

A video at http://www.youtube.com/watch?v=Yd2_FMr0iGY shows the dissection of the udder of a dairy cow that was slaughtered for beef shows the typical infections that can exist in the udders. Research completed by Dr. Derek Forbes has proven that the painful pinching action of a liner with a conventional milking machine will force non-motile bacteria (example: Staph aureus) up the teat canal to cause infections. The video also shows the physical damage in the form of scar tissue that is also a result of the painful milking process with a conventional milking machine.
The following images are from the udder dissection video:

Image of a teat that has been dissected and turned inside out to show the internal flesh. The raised lumps are scar tissue. Scar tissue can form as a result of an inadequate rest phase that damages the tissue and prevents proper milk flow.
