Lakto-ak cluster designed for high yielding cows. Main target on design is minimizing the vacuum fluctuation at teat end, thus accomplished by large claw volume “490 cc” and large liner-claw connection diameter. The inner diameter of the connection to claw 14 mm transfers the milk from liner and the teat immediately to the claw in order to eliminate physical pumping of the milk back in to teat during massage phase. Thanks to patent pending heterogenic design of the liner walls thus starts collapsing from teat top to teat end consecutively, just like hand milking or a suckling calf. Ergonomically designed claw fits perfectly in hand that helps milker for easy attachment or detachment of the cluster. All these features helps for an easy, healthy milking; with the help of lakto-puls pulsators significant yield improvement and remarkable somatic cell count drop should be expected right after start using lakto-ak clusters.
