Document Summary
15 grazing systems and methods: grazing system integrated combination of animal, plant, soil, and other environmental components and the grazing method(s) by which the system is managed to achieve specific results or goals, system vs. Highly variable due to forage species, not uniform architecture: rising plate meters needs to be calibrated using hand clipping and squares. 5: severely underutilized tall fescue pasture, unused production, poor forage quality, wasted money, continuous stocking. 6: problems with continuous grazing, large fluctuations in grazing pressure / forage allowance, example: a tall fescue pasture with a fixed stocking rate of. 3 stocker steers per acre: steady, slow growth in forage need, wide fluctuations in forage growth rate, result: wide fluctuations in gp, fescue grazing pressure under continuous grazing, if we hold aus constant then: 7: changes in forage growth rate changes available forage and alters grazing pressure, what does this change look like, result: wide swings in animal gain rate.
