The Notalim application is an innovative digital solution developed by Wisium. It allows dairy farmers and nutrition technicians to measure the efficiency of the ration in real time. A simple note that allows you to measure the value of fodder, to link feed efficiency and the margin / milk / concentrate and this, by type of ration (corn, hay, dry ration, grass, etc.). Enriched with the watering criterion and the comparison of national and regional groups, the breeder can thus visualize his potential for progress. The feed score is shared with the nutrition technician for better responsiveness in order to optimize the ration in real time so as to avoid negative consequences from both a technical and economic point of view.
