| Abstract | Simuiated &pasture short duration graaing systems were studied in 1985-86 to determine the effect 01 timing and intewdty of graaing on seasonai herbage dynamics. Treatments consisted of 3 grazing scbeduiea (2,3, or 4 rotation cycles per 152 day grazing season) and 2 stoching rates (1.3X and 1.8X the recommended normal). Average ttatonal standing crop increased from 4-cycie to 2-cycie grazing at the iight stoching rate but did not respond to grazing schedule at the heavy stocking rate. Within the graaing season, babage standing crop was affected by graaing schedule in late summer in 1985 but not in 1986. Favorable growhtg conditions redted in Ugbt forage utiiiaation which averaged 39% over all treatments. Net berbap l ccmmdation rates were not affected by any experimentai factor and averaged 34 kg ha-r d-r over all treatments. Time trends for net herbage accumulation rate from May to September were aiso simiiar across treatments. Total herbage disappearance and herbage disappearance per animal-uuitday (AUD) were significantly higher under 4-cycle graaing at the heavier stoching rate than under all other treatments. |
