Farm Systems Modelling

The complex interrelationship among a large number of factors in a farming system makes it difficult to determine the benefit of implementing various management and technologies. Mathematical models are increasingly being used in research both independent and in conjunction with research results. Bio-economic models are capable of simultaneously addressing various dimensions of agriculture such as economic, environmental and sustainability. They can also make a major contribution to guiding experimental research in a variety of ways: these ranges from identification of critical gaps in knowledge or data through to interpretation of experimental results and the development of improved systems of production. Specific areas of research activity include:

• Modelling milk processing efficiency to optimise both dairy farm efficiency and dairy product portfolio
• Whole farm system modelling to reduce greenhouse gas emissions from grass-based dairy and beef production systems
• Derivation of economic values for incorporation into national breeding objectives
• Economic analysis of controlled farmlet experiments
• Economic analysis of controlled farmlet experiments
• Optimising milk production efficiency - heavy soils (Solohead), regional (Ballyhaise) and winter milk (Johnstown)
