Optimal decisions in organic steer production - a model including winter feed level, grazing strategy and slaughtering policy Organic Eprints
Nielsen, B.K.; Kristensen, A.R.; Thamsborg, S.M..
Organic steer production demand several decisions concerning grazing strategy, feeding level in the winter and factors as slaughter weight and length of the fattening period. The production system can be difficult to optimise, therefore the objective of this study was to develop a model to optimise the grazing strategy, feed level in winter and time of fattening and slaughter in organic steer production with regard to economic output at steer level. The steer model is a 4-level hierarchical Markov process with decisions defined at three levels. Decisions taken in the model include grazing strategy (permanent or ryegrass/clover pasture), feed level in winter (high and low), time for beginning of fattening (age 19-27 months) and time of slaughter (age 19-30...
