| Abstract: | The overall objective of this project was to develop a dynamic
model which would determine the optimum replacement rates
for dairy herds under an Irish system of production. A model was designed and applied to the Irish dairy replacement
problem, which included in the decision making process production,
fertility, calving interval, seasonality, month of calving and various
economic factors. The output from the Hierarchic model is a series
of rankings. The dynamic programming approach can enable one to
inform a farmer which cows in the herd should be replaced, on the
basis that a replacement heifer( and its future successors) are
expected to be more profitable than the current cow. The optimum
replacement rate was 17.8% from this analysis. |
