Latin America and Caribbean (LAC) is a developing region characterized for its importance global food security, producing 23 11% of the beef milk production, respectively. The region's ruminant livestock sector however, under scrutiny on environmental grounds due to large contribution enteric methane (CH4) emissions influence climate change. Thus, identification effective CH4 mitigation strategies which do not compromise animal performance urgently needed, especially in context Sustainable...
Brazil is the world's largest beef exporter with commercial cattle herd; however, production cycle needs to be more efficient supply internal and external demands in future. Feedlot operations are currently a reality for Brazilian industry; nonetheless industry still based on grass-fed animals which Nellore breed predominates. At some point this constitutes an important advantage exportations because countries look "natural beef." packing plants regulate use of antibiotics, especially...
Epithelial cells in oral cavities can be considered reservoirs for a variety of bacterial species. A polymicrobial intracellular flora associated with periodontal disease has been demonstrated buccal cells. Important aetiological agents systemic and nosocomial infections have detected the microbiota subgingival biofilm, especially individuals disease. However, non-oral pathogens internalized epithelial their relationship status are poorly understood. The purpose this study was to detect...
Introduction: Dissemination of oral bacteria into the bloodstream has been associated with eating, hygiene, and dental procedures; including tooth extraction, endodontic treatment, periodontal surgery. Recently, studies identified Streptococcus mutans , primary etiological agent caries, as most prevalent bacterial species found in clinical samples from patients who underwent heart valve atheromatous plaque Methods: By using antibiotic protection assays, we tested capacity 14 strains S. to...
Both epidemiologic and experimental findings suggest that infection with Porphyromonas gingivalis exacerbates progression of atherosclerosis. As P. exhibits significant strain variation, it is reasonable different strains possess capabilities and/or mechanisms by which they promote Using have been previously evaluated in the ApoE null atherosclerosis model, we assessed ability W83, A7436, 381, 33277 to adhere, invade, persist human coronary artery endothelial (HCAE) cells. W83 381 displayed...
Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed evaluate different pasture options relation their effect on soil stocks organic matter (SOM) humification. Pastures four beef cattle systems were assessed: intensive irrigated with stocking rate (IHS); dryland (DHS); moderate (DMS); degraded (DP). The under native forest was also evaluated carbon from 0-100 0-30 cm...
The production of beef cattle in the Atlantic Forest biome mostly takes place pastoral systems. There are millions hectares covered with pastures this biome, including degraded pasture (DP), and only small area original has been preserved tropics, implying that actions must be taken by livestock sector to improve sustainability. Intensification makes it possible produce same amount, or more beef, a smaller area; however, environmental impacts assessed. Regarding climate change, C dynamics is...
Aggressive interactions, and their consequences, are the most important causes of poor welfare in piglets. behaviour can be modulated by prenatal neonatal environment several species. Commercially kept pregnant sows often subjected to food restriction, which compromise welfare. Limited information is available on consequences sow hunger during pregnancy outcomes for High fibre diets mitigate feeling and, consequently, it may improve productivity measures. The aim this study was assess...
Methane, a powerful greenhouse gas, is considered to be significant loss of productive potential in ruminants. The objective was evaluate the effect monensin and Acacia mearnsii tannins on ruminal fermentation efficiency cattle. Six rumen-cannulated cows were distributed three diets, each which differed additive used, replicated 3×3 Latin square experimental design. Treatments Control, Monensin (300 mg per animal day or about 18 mg/kg dry matter - DM) tannin-rich extract from (100 g 0.6%...
This study aimed to evaluate the associative effect of monensin and tannins on intake, feeding behaviour, digestibility, rumen kinetics, microbial protein synthesis nitrogen balance. In a 2 × 4 factorial arrangement, 8 cannulated Nellore cows were distributed in contemporary Latin squares received diets that differed level (0.00, 0.75, 1.50 2.25% DM) presence monensin. Monensin was daily administered each cow one square (about 32 mg/kg DM). No interaction between observed (p > .05). Tannins...
Context A challenge for the livestock sector is to improve production and nutritive value of forage grasses through sustainable management strategies. Aims This study evaluated impact on productive five pasture-based systems: irrigated pasture with 600 kg nitrogen (N) ha−1 (IP600); rainfed 400 N (RP400); 200 (RP200); silvopastoral (SP200); degraded without fertilisation (DP0). Methods During two experimental years, samples were collected pre- post-grazing determine nutritional parameters....

The objective of this study was to evaluate the effect different pasture systems on beef steers’ performance, dry matter intake, enteric methane emission, carcass production, forage quality, and animal production per hectare (ha). trial conducted at Embrapa Southeast Livestock, São Carlos/SP, Brazil. Sixty Cachim steers (5/8 Charolais × 3/8 Zebu) with initial liveweights 255 ± 7 kg were evaluated for two years under five grazing (EXT = Extensive; INT Intensive; iCL Integrated crop livestock;...
Porphyromonas gingivalis, an oral anaerobic bacterium, is important etiological agent of periodontal disease and may contribute to cardiovascular disease, preterm birth, diabetes as well. Therefore, genetic studies are crucial importance in investigating molecular mechanisms P. gingivalis virulence. Although tools have been available for many bacterial species some time, manipulations were not developed until more recently remain limited. In this unit, current approaches mutant construction...
It is well known that strain and virulence diversity exist within the population structure of Porphyromonas gingivalis. In present study we investigate intra- inter-species variability in biofilm formation gingivalis partners Prevotella intermedia nigrescens. All strains tested showed similar hydrophobicity, except for P. W83 which has roughly half hydrophobicity ATCC33277. An intraspecies coaggregation with was also found. The association W83/P. 17 produced thickest prevalent. a...
<i>Streptococcus mutans</i> is considered the primary etiologic agent of dental caries and contributes significantly to virulence plaque, especially in presence sucrose. To avoid role sucrose on factors <i>S. mutans</i>, sugar substitutes are commonly consumed because they lead lower or no production acids interfere with biofilm formation. This study aimed investigate contribution cariogenic potential biofilms. Thus, sucrose, glucose, sucralose sorbitol, mass was...
