The objective of this study was to examine the effect humic acid (HA) supplementation on rumen fermentation and protozoal community in rumen. For purpose, four ruminally cannulated Simmental cows were randomly assigned a replicated 4 × Latin square design experiment HA dietary feed utilization, fermentation, for 84 days. basal diet (BD) composed meadow hay (68.2% dry matter [DM]), maize silage (17% DM), granulated mixture (14.9% DM). There treatments, including BD without additives (control diet, H0), supplemented with 50 g HA/cow/day (H50 treatment), 100 (H100 200 (H200 treatment). did not affect total or individual volatile fatty concentrations, protozoa, ruminal pH. However, at dosage g/cow/day increased NH3-N concentration fecal nitrogen compared control (p < 0.001). also significantly impacted abundance genera results suggest that has potential ruminants as natural additive may play role metabolism stabilizing adverse effects fermentation.

ABSTRACT The continuous interaction between phages and their respective hosts has resulted in the evolution of multiple bacterial immune mechanisms. However, diversity prevalence antiviral defense systems complex communities are still unknown. We therefore investigated abundance viral 3,038 high-quality archaeal genomes from rumen. In total, 14,241 31,948 antiviral-related genes were identified. Those represented 114 unique system types grouped into 49 families. observed a high genomes. number systems, families, density varied widely genome to genome. Additionally, per correlated positively with families size. Restriction modification, Abi, cas most common, but many rare present only 1% Antiviral prevalent diverse rumen, few dominant, indicating that rarely present. collection throughout rumen may represent pool mechanisms can be shared by different members community modulate phage–host interaction. IMPORTANCE Phages act antagonistically at cell level have mutualistic microbiome level. This shapes structure microbial is mainly driven mechanism. such mechanism larger than previously thought. Because that, we described genomes, metagenome-assembled (MAGs) isolates, While seem among bacteria archaea, common. suggests these not microbes could community. consistent “pan-immune system” model, which appears common across environments.

Rumen deoxyribonucleic acid viruses that infect and replicate within bacteria archaea are key modulators of the prokaryotic community. These influence community abundance, composition, function impacting host productivity methane production. In this study, viral genomes were assembled from rumen 37 Japanese Black cattle using virus-like particle metagenome sequencing, providing insights into diversity, functional potential, virus-host interactions. The relationship between virome carcass traits, particularly weight marbling, was also investigated. A total 22 942 operational taxonomic units medium-quality or higher (≥5 kb length ≥ 50% completeness), referred to as Viral genomes, reconstructed. Among these, 5973 putative novel genera identified, significantly expanding catalog genomes. Hosts predicted for 2364 units, including carbohydrate-degrading methanogens. Additionally, 27 auxiliary metabolic genes categorized glycosyl hydrolases which responsible degradation cellulose, hemicellulose, oligosaccharides, suggesting may enhance breakdown complex carbohydrates during infection. Furthermore, differed considerably high vs low marbling cattle. Viruses associated with Methanobrevibacter linked weight. This database study provide primary information development improvement beef
