Yesterday I participated in a theme day about Herd Navigator which is the commercial product developed under the Biosens I project. Herd Navigator makes it possible to provide decision support of individual cows in terms of reproduction, health and feeding, giving the farmer a financial benefit per cow per year. The herd manager gains a better overview of the condition of the herd and can take action early against diseases and at the right time for reproduction. Earlier intervention means savings in time and costs and also ensures optimal reproduction control. The product uses a combination of biosensors, IT, statistics and OR techniques. The product won the Agromek prize. The partners are Dansk Kvæg, DeLaval and FOSS.
