Maintaining good fertility is one of the key drivers of efficiency in dairy farming.

By managing reproduction well, dairy farmers can maximise the amount of milk they produce while minimising requirement for additional inputs such as feed and energy. Understanding the factors which affect fertility in UK herds is critical to achieving this.

Current research

A major aim of the group is to maximise value derived from data which is routinely recorded by dairy farmers. This involves:

  • application of “big data” techniques to manipulate and integrate data from different and varied sources
  • analysis of this data using cutting-edge statistical techniques 
  • use of computer simulation models to evaluate relative importance of factors affecting fertility
  • development of decision support tools to help farmers use existing evidence better
