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 can be difficult to optimise, therefore the objective of this study was to describe a model developed to optimise the fattening and slaughter strategy of steer production concerning economy at an individual ...
