Evaluation of the productivity and grazing capacity of cool season grasses

摘要：

Pasture forage is an important part of beef production systems in western Canada and producers require adapted species that are high yielding and provide good nutritional quality.Small plot evaluation of forages uses mowing or clipping to simulate grazing events ; however,these treatments lack animal effects such as pulling,treading,manure and urine deposition and short stubble heights ( Thompson et al.2003 ).Thus,forage varieties need to be evaluated for livestock performance and stand persistence under grazed conditions before they are recommended for use in grazing operations.This study compared hybrid bromegrass,crested wheatgrass and tall fescue for yield and animal grazing days (AGD) over 3 seasons (2005-2007).
