We studied in meroxenic lambs, i.e. in lambs with a simplified digestive microflora, the effect of the microflora on the quantities of solid feed intake and on the main digestive parameters in the rumen. Axenic lambs were inoculated with a more or less complex flora, obtained by diluting (10(-8), 10(-7), 10(-8) a pool of rumen fluid taken either from young conventional lambs before weaning from...

A few studies have shown inconsistent results regarding the association between the visceral fat proportion and colorectal adenomas. We aimed to investigate the association between abdominal fat distribution measured by computed tomography (CT) and colon adenoma.A total of 336 participants underwent physical examination, blood tests, colonoscopy, and abdominal computed tomography at Chung-Ang U...

Twenty-four cross bred steers (BW 452.5 +/- 15.5 kg) were used to evaluate nutrient excretion and odorous compounds in urine and feces of feedlot steers fed diets containing corn wet distillers grains with solubles (WDGS). Cattle were weighed, blocked by BW, and assigned randomly to 1 of 4 dry-rolled corn-based diets containing 0, 20, 40, or 60% WDGS (DM basis). A 96-h total fecal and urine col...

The success of enhanced biological phosphorus removal (EBPR) depends on the constant availability of volatile fatty acids (VFAs). To reduce costs, waste streams would be a preferred source. Since VFAs were shown to vary in the incoming sewage and fermentate from primary sludge the next available source is waste activated sludge (WAS). The opportunity is particularly good in plants where WAS is ...

OBJECTIVE We developed a new method of estimating visceral fat area (VFA) using multifrequency bioelectrical impedance (BI). RESEARCH DESIGN AND METHODS We considered abdominal composition as a parallel circuit model composed of VFA and subcutaneous fat area and calculated the impedance of VFA (IP(VFA)) from this model. The methods were tested against measures of VFA by computed tomography (C...

Dissolved hydrogen (dH) influences the pathways of VFA production and is a precursor of methane formation in the rumen. Measurements of dH in rumen fluid taken at the same time as measuring other rumen fermentation end products would improve our quantitative understanding of the role of dH as a controller of rumen fermentation. Sample collections though a rumen cannula and using oral stomach tu...

BACKGROUND Most studies on the relationships between metabolic disorders (hypertension, dyslipidemia, and impaired glucose tolerance) and hepatic steatosis (HS) or visceral fat accumulation (VFA) have been cross-sectional, and thus, these relationships remain unclear. We conducted a retrospective cohort study to clarify the relationships between components of metabolic disorders and HS/VFA. M...

Four experiments were conducted using day-of-hatch, mixed-sex broiler chicks to evaluate the effects of aflatoxins and T-2 toxin on cecal volatile fatty acids (VFA) and the susceptibility to Salmonella colonization. All chicks in these experiments were challenged orally with 10(4) cfu of Salmonella typhimurium (ST) on Day 3. In Experiments 1 and 2, chicks were fed diets containing 0, 2.5, or 7....

The objective of this study was to determine if a sulfur binder, bismuth subsalicylate (BSS), alone or combined with monensin (MON) could decrease the production of HS by rumen microbes. In Exp. 1, two 24-h batch culture incubations were conducted using a substrate consisting of 50% corn, 40% distillers grains, 9.75% hay, and 0.25% mineral premix, on a DM basis. Five treatments including BSS co...
