Four systems of animal management were applied to a rotationally grazed mixed sward of bromegrass (Bromus inermis Leyss.) and alfalfa (Medicago media Pers.) for a period of 7 yr using yearling beef steers. The systems included (i) put and take stocking; (ii) set stocking at 2.5 steers/ha with surplus herbage conserved as silage and fed later in the season; (iii) set stocking at 3.7 steers/ha, pasture herbage supplemented with oat soilage and (iv) set stocking as in (iii), pasture herbage supplemented with dry-rolled barley. Nitrogen, at the rate of 90 kg N/ha, was applied each spring during the last 4 yr of the experiment. Forage dry matter production varied from 1760 to 5750 kg/ha between years and was highly correlated with precipitation during the growing season. Average daily gains were similar for treatments i–iii at 1.03 kg/head. Feeding supplementary barley increased rate of gain to 1.19 kg (P < 0.01), produced an additional 20 kg liveweight per steer per season and was utilized with an average efficiency of 6.6 kg dry matter per kilogram gain. Average daily gain varied significantly (P < 0.01) between years and was inversely related to dry matter production. The feeding of oat soilage or barley and the harvesting and feeding of silage reduced the variation in gain both within and between seasons compared to the put and take stocking system. Factors affecting the selection of the most appropriate management system by a producer are discussed.

1. Net pasture dry matter production and available pasture dry matter were measured over 3 years in a small-scale replica of the study of the effects of dairy cow grazing management and stocking rate reported by McMeekan & Walshe (1963).2. The four treatments were(i) Controlled rotational grazing, light stocking rate (0.95 cows/acre).(ii) Controlled rotational grazing, heavy stocking rate (1.19 cows/acre).(iii) Uncontrolled, set stocked grazing, light stocking rate (0.95 cows/acre).(iv) Uncontrolled, set stocked grazing, heavy stocking rate (1.19 cows/acre).3. The pasture measurement technique employed measured net pasture production (gains through new growth minus losses from all sources). It is argued that this parameter, rather than absolute pasture production, governs the changes in the dry matter feed supply to the grazing animal.
