Abstract
The data from all published results of grazing trials in which three or more rates of stocking were compared for one or more years were examined. Where possible regression equations and correlation coefficients were calculated. In many cases, a significant negative correlation was found between stocking rate per acre and live‐weight gain per animal per day. In no case was the relationship positive, and no point of discontinuity was found in the linear relationship. The slope of the line appeared to be related to the length of the grazing season; the longer the season, the steeper the slope. The application of these results in practice is discussed in agronomic and economic terms.
