The major challenge for food production in agriculture is the on-going growth of the human population towards 9 billion in 2050 (United Nations Development Goals, 2005). Livestock systems play an important role in agriculture by producing high quality food. In developing countries animals provide not only meat, milk and eggs, but also fibre, fertiliser for crops, manure for fuel and draught power. In developing countries productivity and fitness traits are the major challenge for animal breeding to facilitate production of food by animals and for food supply. In developed countries with intensive animal production systems, health and welfare traits create a new challenge for animal breeders. Healthy and robust animals meet the request for minimising minimizing the use of antibiotics in livestock. In these countries labour labor is expensive. This strengthens te the importance of health and robustness and it stimulates automation of processes in livestock keeping. Robustness in dairy cattle might be assessed by analysing analyzing frequent milk production data as is illustrated in the next picture:
