| dc.description.abstract | Calving management is an important fundamental aspect of successful dairy
operation. With the development of precision livestock farming, namely dairy monitoring
technology, there is surprisingly very little research undertaken. Therefore, it is worth
researching the accuracy of intravaginal thermometers to predict calving. This study was
completed on 257 Hungarian Holstein-Friesian dairy cows to evaluate the accuracy of
intravaginal thermometers (Vel’Phone Sensor - Medria Solutions) to predict the onset of
calving, comparing differences between anterior presentation to posterior presentation and
twin calving. It can be concluded that the intravaginal thermometer can accurately alert the
producer of impending parturition within 48 hours of notification but there is no definitive
differentiation between vaginal temperature changes and presentation of the foetus(es). | en_US |
