As associated member of ICAR CAISLEY offers ear tags approved by ICAR and used for national identification schemes. FLEXOPLUS is a visual eartag with patented, tamper-proof locking system. Using FLEXOplusGENO it is possible to combine the legally mandatory ear tagging with the sampling of tissues in one procedure without any additional work. In comparison to collecting of blood samples or other tissue sample methods mix-ups of samples and animals are eliminated – to 100%. FLEXOtronic is the electronic transponder eartag with a maximum range of identification, a minimum weight and a construction focused on retention and animal welfare reducing the risk of infections and irritations. A lot of digital smart farming solutions like e.g. milking robots identify each animal by electronic ear tag. FLEXOtronicGENO combines the functions and benefits of FLEXOplusGENO and FLEXOtronic.
