Impacts of diet inversion on voluntary intake, digesta and fecal composition, and bacterial community composition in rumen of cattle fed tropical forage-based diets
… days: voluntary intake characteristics, fecal excretion and composition, ruminal digesta compostion, and ruminal fermentation profile. The pattern of the groups along time was interpreted through a non-hierarchical clustering procedure. The diversity of the liquid-associated rumen …

Reduction of minerals in feedlot diets of Nellore cattle: impacts on intake, performance, and nutrient requirements; and prediction of chemical rib section composition by dual energy x-ray absorptiometry in Zebu cattle
… factorial design experiment to evaluate intake, fecal excretion and performance with different levels of minerals. The design included two levels of Ca and P (macro mineral factor; CaP+ or CaP-) and two levels of micro minerals (micro mineral factor; ZnMnCu+ or ZnMnCu-). The factor CaP- was …

THE ROLE OF HEPATOCYTE ATP-BINDING CASSETTE TRANSPORTER A1 (ABCA1) AND APOLIPOPROTEIN M (APOM) IN HIGH DENSITY LIPOPROTEIN (HDL) METABOLISM
… ester (CE) clearance, selective uptake, and fecal excretion compared to control mice and these increases are mediated by increased hepatic LDLr expression. ABCA1 deletion also resulted in diminished recycling of HDL-C taken up by the liver back into plasma. Hepatocyte ABCA1 deletion unmasks a …

Effects of diet on phosphorus digestion in dairy cattle
… forage content decreased IPs-P and TP intake, fecal TP excretion, and total tract IPs-P digestibility (72.4 vs. 61.4%). Fecal IPs-P excretion tended to decrease as increasing forage content. Duodenal IPs-P and TP flow and apparent TP digestibility were unaffected by forage content. Increasing …

Effects of Restraint Stress on Sleep in the Mouse.
… procedures, body weight, adrenal weight and fecal excretion were also recorded.Differential stress related sleep disruptions were observed to occur as a function of intensity and chronicity of stressor exposure. Most of the significant changes in this study were obtained within a single …

Improving estimations of phosphorus bioavailability for lactating dairy cows
… P intake in dairy cows leads to increased fecal excretion of P and a reduction in efficiency of use. Variability in P concentration or availability in feedstuffs can exacerbate P excretion. To investigate variability in P between and within feedstuffs, 170 feed samples (forages, …

Metabolism of halofuginone in rats and sheep fed excreta from poultry administered halofuginone orally
… animals. During the last 5 d of withdrawal fecal excretion accounted for 1.2% of intake with the urine contributing .7%. Levels of 14 C, significantly higher than the control, continued to be excreted in the urine. The kidneys contained modest amounts of radioactivity, although not …

Manure and Nutrient Accretion, Partitioning, and Excretion in Holstein Heifers
… nutrient utilization, partitioning, and excretion are scarce and are becoming necessary. That combined with the fact that feeding programs for heifers are highly variable from region to region and even from farm to farm indicated the need to examine the effects of diet on nutrient …

Short- and Long-Term Effects of Commercially Available Gold Nanoparticles in Rodents
… Species differences in GNP biodistribution and excretion were also detected, with higher relative accumulation of GNPs in spleen and longer fecal excretion in rats. In the long-term (20 weeks after dosing), exposure to GNPs incited chronic inflammation in mice, characterized by the persistence …

The effect of oral contraceptive agents on copper and zinc balance in young women
… by atomic absorption spectrophotometry. Food and fecal nitrogen was assayed by Kjeldahl analysis. Urine nitrogen and creatinine was measured by standard automated techniques. No significant differences were found in the metabolic balances of copper, zinc, and nitrogen. Oral contraceptive users …

Phosphorus Utilization in Lactating Dairy Cows Fed Increasing Amounts of Dried Distillers Grains with Solubles
… feeding of P to dairy cows leads to increased P excretion in feces. Accurate formulation of dairy diets is necessary for two main reasons: 1) phosphorus is the most expensive macro element supplemented in the dairy diet, and 2) it represents the greatest pollution risk if excess is released into …

Investigations into the Mechanisms that Are Responsible for Reduction in Colonic SN-38 Exposure
… that multiple factors, such as higher biliary excretion of SN-38 and SN-38 glucuronide mediated through different efflux transporters, deglucuronidation of SN-38 glucuronide to SN-38 by bacterial β-glucuronidase secreted by commensal microbiota, generation of toxic active metabolite SN-38 from …

Nutritional and genetic characterization of dairy cows managed on pasture-based systems, identifying key aspects to improve their performance
… and fiber digestion and fiber and organic matter fecal excretion were improved after model reparameterization, while body weight and body condition score predictions were improved after model modifications and reparameterization. Although digestion of nutrient was better represented by the new set …
