This study investigated the effects of inorganic and organic minerals on physiological responses, oxidative stress reduction, rumen microbiota in Holstein bull calves (123.81 ± 9.76 kg; 5 months old) during short-term heat (HS) recovery periods. Eight were randomly assigned to four treatment groups: no mineral supplementation (Con), (IM), (OM), high-concentration (HOM) two thermal environments (HS recovery) using 4 × 2 factorial arrangement a crossover design periods 35 d. Calves maintained temperature-controlled barn. The experimental period consisted 14 d HS, condititon, 7-d washing period. Body temperature respiration rate higher HS than conditions (P < 0.05). Selenium concentration serum was high HOM-supplemented both (90.38 μg/dL) (102.00 During period, cortisol 20.26 ng/mL HOM group, which 5.60 lower control group total antioxidant status highest OM (2.71 mmol Trolox equivalent/L), followed by whereas it (2.58 equivalent/L) Plasma malondialdehyde HSP70 levels decreased periods, SOD GPX not significantly affected > principal coordinate analysis represented that overall influenced supplementation; however, temperature-induced microbial structure shifts indicated (PERMANOVA: P At phylum level, Firmicutes Actinobacteria decreased, Fibrobacteres, Spirochaetes, Tenericutes increased 0.05), under conditions. genus Treponema conditions, while Christensenella reduced concentrations calves, suggesting may alleviate adverse HS.
