Conteúdo: | Experiments were conducted in 1967 and 1968 in which Hereford x Friesian (Experiment 1) and Fiesian (Experiment 2) steer calves born in April were turned out to graze at one weck or 3 months of age, respectively, and maintained at three stockling desities in the ratio 1:2:3 animals per unit area. The calves grazed paddocks of S23 perennial ryegrass in rotation, and were moved when the height of grazed stubble at the medium stocking density was reduced to 8 cm. The rate of liveweight gain and herbage intake per head declined as stocking rate increased. When the results of the two experiments were compared, the weight gain of the calves was more closely related to the weight of herbage residues than to the height of the grazed sward. The rate of liveweight gain was depressed when the amount of herbage left after grazing fell below 2000-2500 kg OM/ha (1800-2250 Ib/ac).
