Warner‐Bratzler shear values were determined on four bovine muscles [longissimus dorsi (LD), psoas major (PM), semitendinosus (ST), and biceps femoris (BF)] such that the muscle fibers were sheared at angles approximating 0°, 45°, and 90° to their longitudinal axis. The extent to which shear values were affected by the angle at which the muscle fibers were sheared was similar for LD, PM, and ST; the difference (approx 2.9 kg) in shear value between muscle fiber angles of 0° and 90° being highly significant (P < 0.001). The effect is of sufficient magnitude as to require careful consideration as a source of variation and/or confounding in experiments where treatment effects on Warner‐Bratzler shear values are being assessed.
