YMM = yellow mealworm meal; SBM = soybean meal; GOT = glutamic oxaloacetic transaminase; GPT = glutamic pyruvic transaminase; ROS = reactive oxygen species; MDA = malondialdehyde; SOD = superoxide dismutase; GPx = glutathione peroxidase; CAT = catalase; GSH = glutathione.

Different superscripts were used to show statistical differences at P < 0.05.

SBM was substituted by YMM at 0% (SBM), 25% (H25), 50% (H50), 75% (H75) and 100% (H100), respectively.
