Steers (n = 30) were assigned to one of three replicate breed groups at birth: (1) Holstein (n = 10), (2) crossbreeds comprised of Montbéliarde, Viking Red, and Holstein (n = 10), and (3) crossbreeds comprised of Normande, Jersey, and Viking Red (n = 10). Breed groups were randomly assigned to graze either winter rye or winter wheat during their finishing phase. The results suggest that winter rye and winter wheat cover crops are viable options for grazing cattle, and suggest beef from crossbred dairy steers leads to an improved fatty acid profile and greater consumer acceptability compared to Holstein steers.encrossbred dairy steersfatty acidsforage qualitygrazingmeat qualitysmall grainsForage quality of two cover crop grazing systems and meat quality of organic beef from crossbred dairy steers finished on foragesThesis or Dissertation
