Relative contribution of electrical stimulation to beef tenderness compared to other production factors

Abstract

Aging explained >45% of the variability in beef tenderness, whereas electrical stimulation explained >12%. The effect of electrical stimulation was significant for calf-fed steers up to 27 d of aging. However, this effect did not persist beyond 6 d of aging for yearling-fed steers. However, electrical stimulation prevents cold toughening in lighter, leaner carcasses.
