Prolonged exposure to cold stress in cattle increases basal energy consumption and impedes optimal production. Consequently, herds require adequate attention during cold, extended winters alleviate maintain profitability. This study investigated the effects of oregano essential oil (EO) on body weight (BW), well-being, blood parameters, cecal microbiota. Eighteen steers were randomly divided into two groups (n = 9) fed either a diet (CK) or same supplemented with 20 g/(d·head) EO for 270 days. increased BW by increasing microbial abundance carbohydrate metabolism CAZymes, leading elevated total volatile fatty acids (VFA) levels. Cold activated HPA axis, mitigated reducing serum levels cortisol (COR), corticosterone (CORT), adrenocorticotropic hormone (ACTH), dopamine (DA). well-being decreasing viral species without apparent contribution drug antibiotic resistance development, metabolites primarily enriched growth, metabolism, amino acid pathways. Specifically, tryptophan (2-picolinic acid, quinolinic oxindole) enhanced steer antioxidants (superoxide dismutase (SOD), peroxidases (POD), glutathione (GSH)) inflammatory factors (interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)) following treatment. Notably, low-abundance microorganisms (s_Streptomyces_gardneri, s_Paenibacillus_sp._S09, s_Nocardia_sp._Root136) may play significant role growth immunity. These findings provide fundamental insights how alleviates modulating promotes under influencing mediates microbiota Holstein steers.
