Research
All research carried out has been within the area of model based
decision support in animal production with main emphasis on recurrent
decision problems as for instance the animal replacement problem, where
Markov decision programming techniques have been developed, modified and
applied as a framework for management support in dairy cattle and pig
production. Main results include:
- Development of the notion of a hierarchic Markov process in order to
circumvent the well known dimensionality problem of dynamic programming.
- Introduction of a new criterion of optimality in order to optimize
replacement policies under the milk quota system of the European Union.
- Development of methods for representation of animal traits using
Bayesian updating techniques.
- Development of a framework for dealing with herd constraints as for
instance a limited supply of heifers for replacement.
- Simultaneous optimization of decisions at the tactical and operational
level using multi-level hierarchical Markov processes. A software
system is available.
- Various applications of multi-level hierarchical Markov processes in
pig production, steer production and grass ley management.
- Dynamic
simulation
of a scavenging chicken flock.

Teaching
Herd management has been
taught at undergraduate level since 1986 and post graduate level since
1991. Integrated basic courses (including management, feeding and
housing) are given in dairy production and pig production, respectively.
An advanced course in herd
management is taught separately.
