Abstract

A grazing trial, using the hybrid forage sorghum (Sorghum spp. hybrid) cultivar Zulu, compared rotational grazing (a 4 week cycle, 2 weeks in each of 2 half-paddocks) with conventional continuous grazing at each of 3 stocking rates, 1.92, 2.85 and 4.34 beasts/ha over 3 years. Each year average daily gain was increased (P < 0. 05) by rotational grazing for either the whole or the early part of the grazing period but the advantages measured were slight and are considered insufficient to compensate for the extra expense of fencing and provision of water.
