SUMMARY Pastured broiler growers in the United States typically choose either the faster growing Cornish-crossed (CX) or a medium-growing strain such as Freedom Rangers (FR). However, few yield or meat quality data have been collected from this production method for multiple strains. Therefore, 2 trials were conducted, with 40 broilers of the 2 strains (CX and FR), to determine processing yields and meat color (n = 160). Broilers were obtained at 1 d of age, brooded together for 21 d, and then transferred to common pasture with water and supplemental feed. The FR birds were processed at 83 d and the CX birds were processed at 64 or 71 d in trials 1 and 2, respectively. Carcasses were chilled and cut into parts, and yields and meat color were measured. At 83 d, the FR strain was close to target market weight; at 64 d, the CX were lighter than the FR, but at 71 d, they were heavier. In general, the CX had heavier breast meat weights and higher yields than the FR. There were no differences in wings, legs, or frame weights between strains, but there were some variations in yields for those parts. There was considerable variation in breast meat color between the strains and also between trials, with no definite trend except that FR tended to have more yellow meat. Differences existed between these strains for carcass and parts weights and yields, and although color was variable, the FR strain produced yellower meat than the CX strain.
