A conceptual stocking rate model for the moderately dry mixed and sourveld

Abstract

Results for the 1986/87 season from 15 grazing trials situated at five sites were used to develop a qualitative model describing the relationships between stocking rate and herbage mass and between stocking rate and individual animal performance. Although it cannot be used for predicting stocking rate, it should prove useful for conceptualizing grass utilization levels in glazing management both for maximizing individual animal performance and for acceptable sward utilization.
