Permits maximum teat massage and blood circulation without pinching the teat end. Unlike some inflations, the SP-6000 will not twist in the shell.
SP6000 SILICONE LINER
The Dairy Health Products SP6000 Silicone 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 from 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
The vented funnel and liner shield combination on the SP6000 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 learn more about the Liner Shield)
