This page will help you as a Dairy farmer to discover how SimHerd can help you in your decision making process.

What is SimHerd? 

SimHerd was orignally developed at Aarhus University in Denmark. It is a large simulation model that can calculate all aspects of a dairy herd. All our calculations are herd specific, based on real herd data. The SimHerd Expert model runs a simulation on each cow in the herd over a 10-year period, these results are summarized for the whole herd and replicated 100 times to ensure that the results are valid. 

SimHerd Expert simulates 
among other things the cows: 

  • Milk yield 
  • Feed intake 
  • Reproductive performance 
  • Disease incidence 
  • Longevity 

For example, the program considers, that every third week, there is a chance that the cow comes into heat, is inseminated and perhaps becomes pregnant. Each week the cow also has a risk of becoming ill, being culled, or dyingIn short, all events in the cow’s life are modelled

 “Our mission is to create value for farmers through reliable, sciencebased calculations that aid the decisionmaking process
