Description
Pastures are often either under- or over-grazed, which can affect both pasture sustainability and livestock performance. Disk meter heights were measured for rye (Secale cereale L.) -ryegrass (Lolium L. multiflorum Lam.) pasture to characterize stocking rate (2.5, 3.7, and 4.9 steers/ha) effects on grazing patterns. In another study, grazing indices were calculated for bermudagrass [Cynodon dactylon (L.) Pers.] to describe pasture utilization over time for three stocking rates (3.0, 5.9, 8.9 steers/ha). Distributions of DMH for rye-ryegrass showed distinct grazing patterns for each stocking rate, with the distributions changing from bimodal to multi-modal from heavy to light stocking rates. Bermudagrass was not pattern grazed, but grazing indices showed that the extent that pastures were grazed was not consistent over time for any of the stocking rates.
