Ova studija je imala za cilj da utvrdi uticaj sistema uzgoja na uspostavljanje i razvoj različitih funkcionalnih grupa mikroorganizama u buragu jaradi. Pedeset jaradi je hranjeno kozjim mlekom do odbijanja 45-og dana (TR, tradicionalni sistem uzgoja, n= 25) i 30-og dana starosti (alternativni sistem uzgoja, AR n=25). Jarad iz AR grupe je dobijala rumen starter od rođenja.Obe grupe su konzumirale seno lucerke i mleveni kukuruz od 30-og do 90-tog dana starosti. Iz svake grupe je žrtvovano po 5 jaradi 21, 30, 70 i 90-tog dana starosti. Određivan je ukupan broj protozoa, anaerobnih, amilolitičkih i celulolitičkih bakterija prisutnih u buragu. Jarad iz AR grupe imali su manju telesnu težinu u odnosu na jarad iz TR grupe u periodu između 42. i 56. dana starosti. Kod jaradi iz oba sistema uzgoja 21. dana starosti su ustanovljene anaerobne i amilolitičke bakterije, dok celulolitičke bakterije i protozoe nisu ustanovljene sve do 45-tog dana starosti. Jarad iz AR grupe su imala veće količine anaerobnih i amilolitičkih bakterija do 30., odnosno 45. dana starosti. Ovi rezultati pokazuju da sistem uzgoja ne utiče na vreme i redosled uspostavljanja funkcionalnih grupa mikroorganizama u buragu. Međutim, alternativni sistem uzgoja, koji podrazumeva rani unos čvrste hrane, omogućava uspostavljanje većeg broja bakterija i protozoa. Ipak, efekat zalučenja na rast je bio izraženiji kod jaradi u alternativnom sistemu odgoja, uprkos značajnijem mikrobiološkom razvoju buraga.

BEEF cattle , *SULFUR , *HYDROGEN sulfide , *ANIMAL welfare , *MICROBIAL diversity - Abstract
Sulphur (S) dietary excess can limit productive performance and increase polioencephalomalacia (PEM) incidence in feedlot cattle (FC). Sulphur excess ingested is transformed to hydrogen sulphide (H2S) by sulfo‐reducing ruminal bacteria (SRB), being high ruminal H2S concentration responsible for aforementioned damages. As the ruminal mechanisms involved in H2S concentrations increase have not been elucidated, this study aimed to evaluate the ruminal environment, and the association between ruminal H2S and dissimilatory SRB (DSRB) concentration in FC experimentally subjected to S dietary excess. Twelve crossbred steers were randomly assigned to one of two dietary S levels (6 animals per treatment): low (LS, 0.19% S) and high (HS, 0.39% S obtained by sodium sulfate inclusion at 0.86%). The study lasted 38 days, and on days 0, 22 and 38, ruminal gas samples were taken to quantify H2S concentration, and ruminal fluid to determine total bacteria, DSRB, protozoa, volatile fatty acid and ammonia nitrogen concentration. For ruminal H2S concentration, S dietary × sampling day interaction was significant (p < 0.001), so that the greater concentration was observed on days 22 and 38 with the HS diet. The remaining ruminal parameters were not affected by dietary S level, and no significant correlation between H2S and DSRB concentrations was observed. The ruminal adaptation that maximizes H2S production in FC consuming S excess does not seem to be associated with biological or biochemical alterations, nor DSRB concentration changes. The microbial diversity and ruminal environment were resilient to the S excess evaluated, suggesting that 0.39% of dietary S achieved by 0.86% sodium sulfate addition, could be used without disturbances on digestion nor health of FC.

Ruminant livestock are important sources of human food and global greenhouse gas emissions. Feed degradation and methane formation by ruminants rely on metabolic interactions between rumen microbes and affect ruminant productivity. Rumen and camelid foregut microbial community composition was determined in 742 samples from 32 animal species and 35 countries, to estimate if this was influenced by diet, host species, or geography. Similar bacteria and archaea dominated in nearly all samples, while protozoal communities were more variable. The dominant bacteria are poorly characterised, but the methanogenic archaea are better known and highly conserved across the world. This universality and limited diversity could make it possible to mitigate methane emissions by developing strategies that target the few dominant methanogens. Differences in microbial community compositions were predominantly attributable to diet, with the host being less influential. There were few strong co-occurrence patterns between microbes, suggesting that major metabolic interactions are non-selective rather than specific.

La cepa mutante en el gen iivA de Brucella melitensis 16M (B.m. iivA), que carece de un componente relacionado a la virulencia, fue evaluada en los modelos murino, cobayo y caprino, en comparación con la cepa virulenta Brucella melitensis 16M (B.m. 16M). Con el fin de determinar la virulencia de ambas cepas, se inocularon 10 ratones BALB/c por grupo por vía intraperitoneal. Con la cepa B.m. iivA presentaron bazos colonizados 05/05 y 01/05 ratones a los 8 y 21 dias p.i. respectivamente, mostrando al corte histológico esplenitis con leve a moderada hiperplasia y gran desarrollo de la pulpa blanca. La cepa B.m. 16M colonizó todos los bazos a los 8 y 21 días p.i. Los bazos presentaban esplenomegalia y al corte histológico se observaron lesiones de severa esplenitis con hiperplasia linfoide y gran desarrollo de la pulpa blanca. La inoculación de la cepa B.m. iivA en 12 cobayos por vía subcutánea resultó en la infección de 2 animales e indujo una respuesta inmune humoral en 2 de ellos a los 40 días p.i. Al corte histológico se observó de leve a moderada hiperplasia esplénica. La cepa virulenta infectó a los 12 animales inoculados y todos presentaron respuesta inmune humoral y al corte histológico se observó severa hiperplasia esplénica. En el modelo caprino se inocularon por vía conjuntival dos grupos de 8 animales cada uno. La inoculación con la cepa B.m. iivA resultó en la infección de 4 animales, de los cuales se aisló la cepa a los 14 y 28 días p.i. a partir de los linfonódulos parotídeo y mandibular. A los 42 días se aisló solo de un animal a partir del linfonódulo parotídeo. La cepa B.m.16M infectó a las 8 cabras, aislándose la bacteria a los 8 y 14 días de los linfonódulos parotídeo, mandibular y cervical, y a partir del día 28 se logró aislar a partir de iliacos y supramamarios, bazo e hígado. Los cortes de nódulos linfáticos presentaron linfadenitis, depleción de linfocitos, proliferación de linfoblastos y alteraciones circulatorias. Las lesiones más severas se observaron en cabras inoculadas con B.m. 16M. Los resultados serológicos demostraron que 6 animales inoculados con B.m. iivA fueron reactores a las pruebas serológicas (3 a BPA, 5 a SAT y 4 a FPA), mientras que los 8 animales inoculados con la cepa B.m. 16M fueron reactores al menos a una prueba serológica a los 8 y 14 días p.i., siendo 3 de ellos seroreactores a las pruebas BPA, SAT, 2ME, ELISA, FPA y FC a los 28 y 42 días p.i. La cepa mutante B.m. iivA demostró ser atenuada, logró infectar tejidos, mostrando una virulencia disminuida respecto a la cepa parental virulenta B. m.16M.

- Abstract
While concerns about greenhouse gas (GHG) emissions and animal welfare persist, livestock farming offers unique ecosystem services. In Argentina, where livestock significantly contributes to GHG emissions, particularly enteric methane (CH4), urgent action is required to develop effective mitigation strategies while maintaining animal performance. This study assesses the potential of the inclusion of
Lotus tenuis in natural grasslands to mitigate CH4 emissions and improve forage quality in the Salado River basin, Argentina. Twenty-four beef heifers (361± 19 kg LW) were assigned to two treatments with contrasting botanical composition (LOT: > 80%Lotus tenuis and NG: > 60% grasses). LOT showed better forage quality and reduced CH4 emissions (−17% gCH4/day,p < 0.01;Ym : - 7 to −30%,p < 0.05) compared to NG. However, the condensed tannin content in LOT was insufficient to conclusively attribute any impact on CH4 emissions. This study underscores the potential of promotedLotus tenuis pastures in the Salado River basin to enhance forage quality and mitigate enteric CH4 emissions in free-ranging cattle systems, albeit additional research is necessary to fully comprehend how this practice interacts within the ecosystem and optimise its benefits.

Understanding the functions carried out by the rumen microbiota is important for reducing greenhouse gas production by ruminants and for developing biofuels from lignocellulose. We present 410 cultured bacteria and archaea, together with their reference genomes, representing every cultivated rumen-associated archaeal and bacterial family. We evaluate polysaccharide degradation, short-chain fatty acid production and methanogenesis pathways, and assign specific taxa to functions. A total of 336 organisms were present in available rumen metagenomic data sets, and 134 were present in human gut microbiome data sets. Comparison with the human microbiome revealed rumen-specific enrichment for genes encoding de novo synthesis of vitamin B12, ongoing evolution by gene loss and potential vertical inheritance of the rumen microbiome based on underrepresentation of markers of environmental stress. We estimate that our Hungate genome resource represents ∼75% of the genus-level bacterial and archaeal taxa present in the rumen.

El objetivo fue evaluar el impacto del tipo de contenido ruminal (CR) de ovejas y llamas sobre la capacidad de digestión in vitro de forrajes de baja calidad. Para ello se alimentaron a voluntad con heno de festuca dos llamas y tres ovejas (provistas de cánula ruminal permanente). Los tratamientos consistieron en comparar el CR de llama (n=3) y oveja (n=4) como fuente de inóculos para la incubación de los sustratos (Festuca arundinacea y Paspalum modestum). Se consideró 21 días de acostumbramiento al forraje, y un día para la obtención y procesamiento de muestras (durante dos periodos). Las muestras de CR fueron obtenidas antes de la alimentación diaria, y se determinó la bioquímica ruminal y las poblaciones microbianas mediante PCRq. Por otro lado, los sustratos fueron incubadas in vitro durante 48 h, y se determinó la digestibilidad, parámetros de bioquímicos, parámetros de producción de gas y metano. Los resultados de N-NH3 y ácidos grasos volátiles señalan que el CR de las llamas mostró mayor grado de actividad microbiana que en ovejas (P< 0,001). La densidad de protozoos ciliados fue mayor para las llamas en comparación a las ovejas (5,0 vs 3,6 ×104 células/mL; P= 0,010). Sin embargo, no se evidenció diferencia en la densidad de bacterias y metanógenos totales, tampoco en las bacterias fibrolíticas. Por otro lado, la digestibilidad de MS, MO y FDN y el potencial de producción de gas fueron mayores para el CR de las ovejas (P< 0,001). Se concluye que el CR de las llamas presentó mayor grado de actividad microbiana que las ovejas cuando fueron alimentadas con forrajes de baja calidad. No obstante, el licor ruminal de la oveja presentó mayor capacidad digestiva por presentar valores superiores de digestibilidad y producción de gas respecto de la llama.
