Heat stress significantly impacts dairy cow productivity, health, and welfare. This study evaluated a self-developed herbal formula as dietary intervention to mitigate heat stress. A total of 198 lactating cows were divided into two groups: Control group receiving standard mixed rations Herbs supplemented with for 60 days. Various parameters assessed, including milk yield composition, antioxidant capacity, immune responses, stress-related gene expression, rumen microbial composition. Compared the group, in showed improved feed intake, quality, rumination frequency, enhanced activity response. Rumen microbiome analysis revealed reduced relative abundance Proteobacteria Ochrobactrum along an enrichment beneficial genera such Lachnospira . Functional predictions indicated that exhibited glycolysis/gluconeogenesis, pyruvate metabolism, starch sucrose reflecting fermentation efficiency energy utilization. In conclusion, physiological biochemical attributes, boosted modulated microbiome, contributing alleviation cows. These findings highlight its potential natural strategy support health productivity under conditions.

ABSTRACT Genetic features of host adaptation S. aureus to ruminants have been extensively studied, but the extent which this occurs in nature remains unknown. In New Zealand, clonal complex 1 (CC1) is among most common lineages humans and dominant lineage cattle, enabling between‐, within‐CC genomic comparisons epidemiologically cohesive samples isolates. We assessed following benchmarks 277 from small ruminants, humans, pets: 1, phylogenetic clustering ruminant strains; 2, abundance homo‐specific ruminant‐adaptive factors, 3, scarcity heterospecific factors. The were complemented by comparative analyses metabolism carbon sources that abound milk. identified fulfilling three virtually all isolates, including CC1. Data suggest virulomes adapt niche sensu lato accross CCs. CC1 forms a ruminant‐adapted clade appears better equipped utilise milk than human Strain flow across human–ruminant interface only occur occasionally. Taken together, results specialisation, rather mere adaptation, clarifying why zoonotic zoo‐anthroponotic transmission between has hardly ever reported.

Staphyloccous aureus belonging to sequence type 5477 have recently been identified as a predominant clone causing bovine mastitis in Rwanda and Tanzania. We compared nine S. ST5477 17 isolates other types by their biochemical profile ability acidify milk grow minimum media containing lactose. found that all were positive ONPG (o-nitrophenyl-β-D-galactopyranoside) test negative for mannitol fermentation potentially challenging the correct identification of this aureus. In addition, much faster acidifying grew minimal with lactose strains suggesting an increased utilization thereby adaptation udder environment possible reason recent successful emergence. Comparison lac gene region genome sequenced reference showed both contained known lacABCD genes involved degradation, but had 12 amino-acid deletion two differences transcription regulator, might play role. conclusion, these preliminary data suggests improved may key feature success adapted clone.
