The ability of heavy, light, and variable stocking, rotational spelling (R/Spell) and a SOIVariable strategy to cope with rainfall variability was tested over 8 years. Individual annual live weight gain (LWG/hd) was consistently higher under light than under heavy stocking, with LWGs in other strategies intermediate between these levels. LWG/ha was highest under heavy stocking but the strategy was not sustainable, requiring feeding and partial destocking in dry years. Pasture composition and yield were best in the light and R/Spell but poorest under heavy-stocking. Overall, light gave superior pasture condition and individual animal performance and reduced costs relative to heavy stocking. The SOI, Variable and R/Spell strategies show promise as a means of coping with rainfall variability but all require further testing.
