“…It was estimated that, in a 250-kg heifer, this DMD difference could reduce livemass gain by 10 kg over 180 days. Thus the restricted opportunity to select a diet of high digestibility, under rotational relative to continuous grazing, could account for almost all the reported (Kreuter, et al, 1984) livemass gain difference between these two grazing systems on East Griqualand sourveld.…”

“…The mean 180-day livemass gains per 250-kg heifer, corresponding to these NEg values, were 52,2 kg and 62,1 kg respectively. These gains and the 10-kg difference approximated the observed mean livemass gains under the two grazing systems in the preceding trial (Kreuter, et al, 1984). Thus, theoretically at least the observed mass gain differences could be accounted for almost exclusively by a 2% DMD difference in the selected diets.…”

“…All treatments commenced and terminated on the same days. Stocking rates were selected to correspond with the previous grazing trial (Kreuter, et al, 1984). Between six and eight heifers were allocated to each treatment, according to the area fenced for it, to achieve two fixed levels of stocking: 1,0 and 2,3 heifers/ha i.e.…”

Stafford Smith2 'CSIRO Division of Tropical Crops and Pastures, PMB, Aitkenvale, Qld 4814 2CSIR0 Division of Wildlife and Ecology, PO Box 2111, Alice Springs, NT 0871 Abstract Stocking rate is the most important management variable affecting productivity and stability in rangelands. In this paper we examine the relevance of stocking rate research to the complex and highly variable ecosystems that make up most rangeland enterprises. We review a number of stocking rate experiments that have been conducted in both rangelands and more intensively grazed, improved pastures and demonstrate a fundamental difference in the nature of the stocking rate - animal production relationship between the two environments. Animal production in rangelands is less sensitive to increases in utilisation rate than in improved pastures, at least in the short to medium time frame of most experiments. These differences can largely be explained by factors relating to the much greater spatial and temporal variability of rangelands such as: inter-annual and seasonal fluctuations in vegetation composition and quality; long-term vegetation changes; and spatial and temporal patterns of diet selection in complex vegetation. Together, these factors limit the application of linear stocking rate models to complex rangeland environments for prediction of animal production responses. We suggest that dynamic simulation models, which incorporate the spatial and temporal variability of rangelands, may be the best way of developing simple but useful management principles for setting stocking rates that are more appropriate than simplified regression relationships.
