An economic analysis of heifer rearing and breeding selection in GB

Aims & Objectives
To enable farmers to optimize their heifer rearing system for greater profitability thereby improving the viability of the UK dairy herd.

  • Develop a flexible heifer-rearing model structure that represents the complex biological, economic and social interactions which can be modified according to the farmer's management strategy
  • Conduct an analysis of the direct and indirect costs of rearing heifers in the UK dairy industry
  • Determine the benefits of including heifer growth and fertility traits in selection indices
  • Determine farm-level and national impacts of current genetic selection indices for lactation yield versus longevity using a cost-effectiveness framework.

Expected Outcomes

  • Accurate data on the cost of heifer replacement in different management systems accounting for the cost of prematurely culled animals
  • Identify critical management decision points during the rearing process
  • Estimation of longevity index (LI%) to cover the costs of heifer replacement in different management systems
  • Cost-effectiveness analysis of the best selection trait(s) for lactation yield, longevity and overall herd sustainability.
