Traditional Chinese medicine (TCM) prescription or rumen‐protected GABA (RP‐GABA) can effectively relieve the heat stress (HS) in cattle, but the joint effects of TCM and RP‐GABA on HS in beef cattle are not fully clarified. To investigate the effects of TCM or/and RP‐GABA on growth performance, antioxidant capacity, serum parameters and heat shock proteins (HSPs) expression in beef cattle under HS ambient. A total of 40 Jinjiang yellow cattle were randomly divided into four groups: (a) control group (basal diet, BD), (b) TCM group (BD+TCM), (c) GABA group (BD+RP‐GABA) and (d) TCM+GABA group (BD+TCM plus RP‐GABA). Results indicated that the average daily feed intake (ADFI) was significantly elevated in the TCM+GABA group ( p < 0.05), whereas, average daily gain (ADG) was elevated ( p < 0.05) in the group of TCM (38.5%), GABA (35.4%) and TCM+GABA (41.5%) compared with the control group. Meanwhile, TCM+GABA exhibited prominently more positive effects in terms of SOD, BUN, T‐CHO, TG, HDL‐C and HSP70 ( p < 0.05 or p < 0.01) than the control and other treatment groups. Therefore, TCM or GABA can effectively moderate the HS response in beef cattle by ameliorating antioxidant capacity, serum parameters and HSPs expression, meanwhile, the combination of them exerts a synergistic effect on HS alleviation.
