A total of 24 red Angus steers (BW = 431.2 ± 10.4) were sorted by BW and allocated in 4 pens (6/pen) equipped with a Calan Broadbent Feeding System to assess the effect of metabolizable energy intake (MEI) on carcass quality during the summer in southern Chile, and then allocated into one of 2 treatments 1.85 × or 2.72 × MEI for maintenance. Animals were fed once per day with the same diet, and treatments were applied by controlling DMI. Climatic data were obtained from a weather station located at 5 km southeast to assess animal thermal comfort by mean of 2 thermal indices (THI and the Comprehensive Climate Index). The study considered a period of 84 d on feed plus 19 d of pre-experimental period to allow the animals get used to the facilities and feeders. Finally, steers were slaughtered on 04/28/2014 in Temuco, where carcass data including hot and cold carcass weight, KPH, muscle pH, rib eye area, marbling score, and back fat were collected between 9th and 10th rib, after 48 h post slaughtering. All data were analyzed under a randomized complete block design arrangement (α = 0.05), with each steer an experimental and observational unit. The pH values in both treatments were considered suitable, 5.57 and 5.52 ± 0.05 for T1 and T2, respectively (P = 0.42). Values of back fat observed did not show differences (3.92 and 3.87 ± 0.77 for T1 and T2, respectively; P = 0.96). In the case of average values for rib eye area and KPH were also similar between treatments (P > 0.05). Finally, hot carcass weight was also similar between treatments (P = 0.15). Therefore, no differences between T1 and T2 were observed for carcass quality of steers finished during summer time in any of the variables measured. In addition, based on the thermal comfort indices assessed, animals did not suffer heat stress, being able to deal in good shape the summer season. The latter mainly due to the large temperature drop as resulting of cold nights and the availability of water. On the other hand, there were no differences in ADG (0.95 vs. 1.25 ± 0.15 kg/day for T1 and T2, respectively; P = 0.18). Based on the data herein collected we can conclude that for southern Chile conditions during summer time, MEI had no effect on beef carcass quality
