Simulating options for managing seasonal and annual variations in feed supply of mixed crop/ livestock systems in sub‐tropical Australia
Mixed crop/livestock systems in subtropical Australia are based on a variety of summer and winter growing crops and forage species, but summer active grass‐based pastures (both native and improved) are the predominant forage source used for livestock in the region.Rainfall in the region is summer dominant (65％ of annual) and has a high degree of seasonal and inter‐annual variability (26％ ‐34％ CV).In this unpredictable climate, managing variability in forage supply for livestock both within years and between years is a major challenge.Simulation modelling was used to demonstrate strategies for mixing grass pastures and forage cropping that can reduce variability in whole‐farm feed supply.
