Description: Need to timely detect estrus in cows or heifers? Ovi-bovi activity tags grant wireless range of up to 5 km and 10 years of operation, for €60 per tag.
Ovi-bovi cow heat sensor continuously tracks animal’s activity and transmits the data for a distance of 2 to 5 km in license-free 433 MHz band From economic perspective, detection of ovulation in cows is a major challenge for modern dairy farming worldwide. The onset of ovulation is preceded by the period of estrus, or heat; it is time when cow behaves quite specifically and lends itself to visual identification. But with average farm size growing, visual heat detection becomes less and less reliable. Metho
Ovi-bovi receiver in robust metal casing with two sockets, one for the SMA -type antenna connector and another one for the PoE cable Ovi-bovi system is heighly efficient for heifers too, starting from 12 months age, as the ones pictured here (Chachkovo farm, Minsk region) For timely and accurate detection of estrus in dairy and beef cows and heifers we have developed wearable non-invasive collar-placed activity tags — bringing in our expertise in m2m wireless communications and building upon the experience
Ovi-bovi tags fit any standard 4 cm wide collar with no need to keep any specific sensor position and orientation. Expected battery life of each tag is over 10 years ; if necessary, a tag can be swapped from a cow to another cow anytime, with the new cow ID associated with the tag’s ID in the database. Cow activity data is transmitted by a tag every 20 minutes in ten-minutes chunks over 5+ km from the tags to the receiver (actual range is dependent on receiver antenna elevation, type of terrain and other de
