Grazing Management and Use of Ryegrass

Annual ryegrass (Lolium multiflorum Lam.) planted on a prepared seedbed often provides fall grazing; however, most planted areas of ryegrass are sod-seeded which usually does not provide adequate forage production for continued, uninterrupted grazing in the southeastern USA until late December to mid-February. Rapid forage growth during March to late May often requires frequent increases in stocking density to efficiently use ryegrass pastures. Annual ryegrass is very tolerant of frequent and severe defoliation regimens and often supports 2000 kg ha−1 body weight for a 75 to 100-d period in the spring. On average, individual daily gains for respective animal classes are: suckling calves (Bos taurus), 1.25; stocker calves, 1.05; yearling horses (Equus caballus), 0.80; lambs (Ovis aries), 0.15; and fallow deer (Dama dama), 0.12 kg d−1. Depending upon management and climate, stocker calf gain per unit land area may range from 450 to 900 kg ha−1 from annual ryegrass pastures. Flexible grazing management systems that include variable stocking densities are usually necessary to ensure optimum biological and economic efficiencies.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
