Carcasses of “A” maturity from 3,182 yearling steers were used to assess the influence of quality factors and slaughter location-trial and (or) graders upon final quality grade. These steers were part of a study involving 16 trials (eight summer and eight winter) concerned with housing and feeding systems for feedlot cattle under northwest Iowa conditions.Marbling score was the primary factor determining final quality grade with a standard partial regression coefficient of .82 (P<.01), while the remaining quality factors had standard partial regression coefficients of .12 (P<.01) for conformation, .08 (P<.01) for color of lean, .04 (P<.01) for texture of lean, .03 (P<.01) for firmness of lean, and −.02 (P<.05) for texture of marbling.When slaughter location-trial was included in a model with the quality factors, 14% of the total variation in final quality grade could be explained by slaughter location-trial and 71% by slaughter location-trial and marbling. With the addition of the remaining quality factors 87% of the total variation was accountable. |
