Two trials, involving a total of 300 steers, were conducted comparing feeding up to time of slaughter with fasting for 1, 2 and 3 days. Fasting reduced slaughter weight of steers tested with greatest weight losses the first 24 hr., but fasting up to 2 days did not affect carcass yield. Both hot and chilled carcasses of steers fasted 3 days weighed significantly less than carcasses of steers not fasted. However, fasting had no detrimental effect on marbling score, maturity score or final carcass grade, while it significantly improved the color of lean in carcasses of steers fasted 1 or 2 days. The economic advantage of withholding feed from cattle for up to 2 days prior to moving them from feedlots to packing plants is obvious if they are not sold on a live weight basis. |
