This study hypothesized that combining oregano essential oil (OEO) and yeast cultures (YCs) would modulate rumen microbiota to promote gastrointestinal homeostasis function. Twenty-four newborn, healthy, disease-free, crossbred Simmental male calves (birth weight ≥ 35 kg) were assigned one of four treatments based on birth data. Treatments as follows: (1) Control (CON), fed calf starter without additives; (2) OEO, containing 60 mg/kg body (BW) OEO per day; (3) YCs, 45 BW YC (4) MIX, with (60 mg/kg, BW) (45 combination. The experimental period lasted 70 days. Rumen fluid was collected the final day, 16S rRNA sequencing performed assess alterations in microbiota. Calves MIX exhibited significantly greater microbial richness, species diversity, lineage diversity (p < 0.05) compared other groups. MIX-fed also showed changes relative abundance certain species, identified through LEfSe analysis (LDA > 4, p 0.05). These biomarkers included f_Rikenellaceae, g_Rikenellaceae_RC9_gut_group, g_Erysipelotrichaceae_UCG-002, c_Saccharimonadia, o_Saccharimonadales, f_Saccharimonadaceae, g_Candidatus_Saccharimonas. Pathways enriched involved nucleotide metabolism, lipid glycan biosynthesis amino acid terpenoids polyketides antimicrobial drug resistance, xenobiotic biodegradation antineoplastic excretory system pathways. In conclusion, this demonstrates combination enhances community modulation more effectively than or YCs individually control diet.

Ruminants play a crucial role in the food chain, but are also considered contributors of greenhouse gas (GHG) emissions . Essential oils (EOs) emerging as natural feed additives ruminants' nutrition to enhance animal health, performance and reduce environmental footprint. Among EOs, lemongrass (Cymbopogon winterianus) oregano (Origanum vulgare) EOs (LEO OEO) have attracted attention modulators ruminal fermentations, their needs be clarified. The experiment was designed using randomised setup assess effects LEO OEO on vitro fermentation GHGs, total mixed ration (TMR) substrate (incubation time 24h). Experimental treatments included (doses % TMR DM basis): 1) control only (0% EOs) 2) 0.07% 3) 4) 0.035% + 5) OEO. Each treatment repeated three times two experimental runs. Only EO combinations reduced (−9%, p=0.001). All decreased CO2 by −5 −12% with no significant differences between (p<0.001), although anti-methanogenic were not observed (p=0.192). Volatile fatty acids slightly affected blend at highest dose, resulting reduction propionate (−1.3%, p=0.02), an increase acetate:propionate (+0.16%, p=0.04) isovalerate (+0.7%, p=0.03). pH (−0.6%, p=0.004), while increased oxidation capacity (+4.2%, both parameters remained within physiological ranges. Canonical discriminant analysis confirmed distinct effects, highlighting potential for improving mitigating ruminant

Antimicrobials long been used to enhance the performance and immunity of rabbits, typically by adding them feed or drinking water prevent illness. However, increasing consumer concerns about antibiotic-resistant microorganisms have led a shift toward natural, eco-friendly, non-antibiotic supplements that can improve rabbit health productivity. Recently, aromatic herbs their extracts gained considerable attention as natural antioxidants with growth-promoting health-boosting properties. Essential oils secondary metabolites play central role in these effects, Origanum vulgare (oregano) emerging standout option. Compared synthetic alternatives, oregano is residue-free supplement fewer harmful side effects. Its key bioactive components, thymol carvacrol, shown deliver significant benefits when incorporated into diets, particularly improving production performance, immunity, antioxidant capacity. Supplementing diets essential oil (OEO) has found growth efficiency, meat quality, while also lowering cholesterol levels boosting activity. Despite promising results, research on use farming remains limited. This review aims provide an up-to-date overview potential effect supplements, parameters, carcass hemato-biochemical capacity, response, gut health, gene expression rabbits.
