SILICONE
SP-6000 LINER
The Silicone
Plastics™ SP-6000 liner offers several significant advantages,
which improve udder health and milking performance. These include
better teat end health, smooth liner surface, long use life, and
anti-impact features.
Better Teat
End Health
For over ten years there have been predictable teat end health benefits
seen from using the SP-6000 liner. The three sides of the liner's
triangle shape distributes the massage force on the teat and thus
reduces the pinch effect as is seen with two sided liners. In addition,
the softer massage of this medical grade silicone material further
reduces the squeeze force on the teat end. The reduced callous formation
at the teat orifice has been documented at research trials in Utah
as well as on thousands of cows that Udder health Systems has monitored
as they have gone form round liners to SP-6000's. Our data shows
that cows with rough teat ends are more likely to become infected
with Staph. Aureus than cows with smooth teat ends.
Medical Grade
Silicone
The silicone material is inherently much smoother, even after 6000
milkings than brand new rubber liners. This makes the silicone liner
easier to clean because it does no absorb milk solids and harbor
bacteria in crevices as is typical with rubber liners. The silicone
compound used in this liner has good milking properties and gives
a very stable performance over its 6000 milking rated use life.
The long life of the liner, along with the labor saved in not having
to change liners frequently, make the SP-6000 very economical to
use.
Liner
Shield and Liner Vent (click

The vented funnel and liner shield combination on the SP-6000
provides a high level of protection from teat end impacts. Teat
end impacts with bacteria laden milk droplets due to pressure
fronts or vacuum fluctuation in the unit are one of the main
mechanisms of infection associated with the milking machine.
Liner slipping may be the most common source of problems in
this area even on the newest milking installations. Experimental
evidence points to the conclusion that vacuum fluctuations by
themselves are not dangerous to the cow unless they cause aerosols
of milk droplets with bacteria to be thrown at and impact the
teat orifice. These teat end impacts can force bacteria backward
through the teat orifice, leading to infection of the gland.
In the late seventies the National Institutes for Research in
Dairying, in England evaluated various design elements to protect
the teat form impacts. They looked at liner venting, quarter
milking clusters, and liner shielding and measure their effect
on reducing the frequency of teat end impacts. This work indicated
that shield prevented penetration of the teat canal 70% - 90%
over controls. They showed that shield prevented transfer of
bacteria within the cluster to the protected liner about 50%
of the time as did short milk tube air venting. Together, the
shields plus the short milk tube air venting reduced bacterial
transfer over 90%. (click here to
