Abstract
Abstract Lamb production from pastures under continuous and rotational grazing was compared for 3 years at stocking rates of 20, 30, and 40 ewes/ha with and without initial pasture reserves. Lamb growth rate was similar for each grazing system and was increased when feed reserves were present. Increasing stocking rate lowered per animal performance but increased output/ha. Ewe live weights declined in 2 of the 3 years. Rotationally grazed ewes maintained body weight better than continuously grazed animals. In the 4th year, pastures were maintained at differing heights and lamb output was higher from long pastures. Continuous grazing gave higher gains than rotational grazing and there was no difference in lamb or ewe performance between 1-day and 4-day rotational shifts.
