Abstract
A simulation model was used to investigate the
effects of various combinations of stocking
rate, drafting weight and lambing season on a
hypothetical dryland farm in Canterbury. A
selection of physical results is presented and financial implications of alternative
management strategies are briefly discussed. Stocking rate and lambing time had
considerable effects on animal performance,
with minor effects from drafting weight. Gross
margins were considerably affected by stocking
rate; the highest return was obtained with
conventional lambing at 15 su per ha and
drafting lambs at 30 kg empty body weight.
