Description
Brigalow (Acacia harpophylla) regrowth was aerially treated with 2.0 kg/ha tebuthiuron (Graslan TM) at Blackwater, Australia in November 1989. Control of brigalow regrowth increased in grass production 2- fold, which resulted in dramatic animal live-weight gains. The liveweight advantage of steers grazing the tebuthiuron treated area was 31 kg/head compared with similar steers grazing the control paddock at similar stocking rates. After 20 months this advantage enabled 44% of stock to be marketed at premlum prices. A subset of steers implanted with a long-term hormonal growth promotant (HGP) (Compudose400™) and grazing the tebuthiuron-treated paddock recorded a 75 kg advantage over untreated control animals. This advantage enabled the early sale of 88% of this group at premlum market specifications. Steers implanted with HGP grazing the control paddock recorded a 29 kg advantage over their untreated companions.
