Fresh beef quality from cattle fed field peas during pasture and finishing phases of production

This study evaluated the use of field peas during two phases of production on fresh beef quality. Cattle (n = 232) were assigned to one of six dietary treatments in a 3x2 factorial design consisting of 3 pasture and 2 finishing supplementations. The pasture phase consisted of 1) no supplement, 2) field peas at 0.5% body weight (BW), or 3) dry-rolled corn supplement at 0.5% BW. The finishing phase consisted of 1) no field peas or 2) field peas at 20% dry-matter basis. Strip loin samples, aged 14 d, were subjected to retail display (RD) for an additional 7 d. Tenderness via Warner-Bratzler shear force (WBSF) and Slice Shear force (SSF), objective (L*, a*, and b*) and subjective color, lipid oxidation (TBARS) and fatty acid composition were evaluated. Dietary treatment had no effect on tenderness. Steak discoloration was low ( 0.05) were unaffected by dietary treatments. Field peas may be used for cattle with minimal negative impact on fresh meat quality.
