摘要: One-hundred and forty four weanling bulls of Angus (A, n = 48), Simmental x Hereford (SH, 48) (S, breeding were either castrated, left intact, intact implanted with Ralgro or Synovex S. Cattle slaughtered after 190, 246 315 days high-energy feeding, the right side each carcass was electrically stimulated. Sensory analysis conducted on longissimus dorsi steaks 5 aging Warner-Bratzler shear force (WBS) measured 5, 10 15 aging. Steers had lower (P < 0·05) WBS more desirable sensory panel scores for juiciness, ease fragmentation, amount connective tissue overall tenderness than all treatments. The implanting synthetic steroid hormone compounds did not make a practical improvement in beef tenderness.
