Abstract

Twenty pasture-fed steers and 10 pasture-fed heifers were evaluated for relationships among daily BW gain, grazing period, frame size, final weight, and carcass traits (fat thickness, ribeye area, marbling score, and YG). Cattle were wintered for a BW gain of 0.69 ± 0.03 kg/d for 156 d postweaning and were maintained in adjacent, rotationally grazed paddocks containing primarily cool-season grasses. Cattle were slaughtered at a constant age (532.9 d ± 5.7 d) in 6 slaughter groups and carcass data were collected. Three LM steaks were taken from each of the carcasses and consistently labeled for position on the 9th- to 12th-rib section of the LM. One steak was evaluated for Warner-Bratzler shear force. An additional steak was used to determine the total lipid, fatty acid, and cholesterol composition of the steaks. Correlations were determined for the relationship of production and carcass traits with the fatty acid and cholesterol profile. Animal, growth, and carcass traits were generally not strongly related to fatty acid and cholesterol content of cooked steaks from pasture-fed cattle slaughtered at 533 d of age.
