Description
Annual live-weight gain of steers grazing on virgin tropical semiarid poplar box (Eucalyptus populnea) savannah woodland in subcoastal central Queensland fluctuated between 59 kg/head and 200 kg/head over a 7-year period. Average live-weight gain for the 7 years was 136 kg/head/year, which is above expected levels for this vegetation type. Reasons suggested for this animal performance are the use of a stocking rate more lenient than the district average and above-average winter rainfall received during the 7 years of this demonstration project. Removing trees doubled the pasture dry matter yield, which subsequently allowed a doubling of stocking rate for similar per head live-weight gain. These data suggest that local cattle producers do have avenues for Improving their production, but the use of lenient stocking rates on this vegetation type is recommended.
