Evaluation of Internal Markers for Predicting Digestibility and Fecal Output by Cattle Fed Bermudagrass Hays of Varying Quality
… lignin (ADL) to predict digestibility (DMD) and fecal output (FO) by cattle fed bermudagrass <em>[Cynodon dactylon </em> (L.) Pers.] hay-diets categorized by their low (L), medium low (ML), medium high (MH), or high (H) CP concentrations (79, 111, 131, and 164 g/kg DM, respectively) was …

Pasture Intake, Digestibility and Fecal Kinetics in Grazing Horses
… been the use of markers, or tracers, to estimate fecal output and nutrient digestibility. External markers are dosed to the animal and can be used to determine fecal output. Internal markers are an inherent part of the diet in question and can be used to determine dry matter and nutrient …

Seasonal differences in apparent digestibility and intake of tall fescue by horses
… of Yb impregnated fescue forage at 0 h, and fecal grab samples were taken at 6, 12, 18, 24, 30, 36, 48, 60, and 72 h after dosing. Fecal output was estimated from Yb concentration in the feces. Apparent digestibilities of dry matter (DM), acid detergent fiber (ADF), neutral detergent fiber …

Estimating forage mass of tall fescue pastures and dry matter intake and digestibility of fescue forage by beef steers
… 7 d of the collection period. Likewise, actual fecal output, dry matter intake, and digestibility were not different from the estimated values. However, estimated values had to be adjusted for the respective recovery rate. The third experiment was conducted under grazing conditions to evaluate …

Nutritional status of beef cows grazing reclaimed strip mined pastures
… were used to estimate organic matter intake, fecal output and digestibility. In addition to samples taken during the trials, blood samples and hand plucked forage samples were taken monthly for 11 mo prior to the trial period. In late summer esophageal masticate samples had a low fiber …

Soybean hulls as a dietary fiber source in canine and feline diets
… 10 d of diet adaptation followed by 4 d of total fecal and urine collections. At the end of each period, a blood sample was collected and analyzed for serum chemistry. Food was offered twice daily and fed to maintain body weight. In the first study, eight adult female beagles (mean age = 4.6 ± 0.6 …

Potato pulp as a dietary fiber source in high quality dog foods
… of PP increased, as did concentrations of fecal SCFA. Furthermore, fecal consistency, total fecal output, fecal protein catabolites (except spermidine), and fecal dry matter output were not affected by increased inclusion levels of PP. Overall, PP was characterized as a moderately …

Understanding the reproductive biology of giant pandas: predictive biomarkers for reproductive success
… were corroborated with androgen profiles and fecal output profiles to provide a set of pregnancy biomarkers in giant pandas. Knowledge of female giant panda reproduction has been expanded. These results have additional use in the real-time monitoring of captive giant panda reproduction …

Studies on the Synthesis and Metabolism of 1-(l-Arginine)-1-Deoxy-D-Fructose and the Possible Mutagenic Effects of Maillard Reaction Mixtures
… in expired CO(,2) for the fructose-arginine and fecal radioactivity was greater than that seen for the arginine. High levels of antibiotics in the diet had little effect on the absorption of arginine except that diarrhea led to increased fecal output. The effect of antibiotic pretreatment on the …

Alkanes as Internal and External Markers in Horses and the Digestibility of a High Fat Cereal By-Product
… in incorporating supplements in their diets. Fecal recoveries (R), fecal output (FO), dry matter digestibility (DMD) and dry matter intake (DMI) were estimated using alkanes as markers in 8 thoroughbred geldings. The experiment compared two diets in a 2 X 2 latin square experiment. The diets …

Digestion and utilization of nutrients in diets containing feather meal and (or) supplemental fat by lactating dairy cows
… VFA's, or rumen bacteria AA. Intake and fecal output of total, essential, and non-essential AA were greater when cows were fed diets containing feather meal. However, flow of AA to the duodenum, AA absorbed, and AA digestibilities did not differ. Results suggest that bypass proteins with …

Evaluating glucose-based carbohydrates for use in canine diets
… macronutrient digestibility, and effects on fecal characteristics, microbiota composition, and fermentative end-products. Our first aim was to determine the chemical composition of carbohydrate sources commonly incorporated into pet foods. We evaluated various whole grains, processed grains, …

Fecal Kinetics and Digestibilities of Hays and Supplements Estimated by Marker Methods in the Horse
A marker model of fecal kinetics using chromic oxide (Cr) or ytterbium chloride (Yb) is being developed for grazing horses. The model consists of removal of feces at a constant rate from a single compartment, the prefecal mass. It was tested in experiments on stall-fed horses in the context of …

Intake, Digestibility, Insitu Disappearance and Ruminal Fermentation of Bermuda Grass Hay by Lactating Beef Cows Offered Corn or Hominy Feed as Supplements
… Titanium dioxide was used as an external marker. Fecal samples were collected twice daily to estimate fecal output. Five consecutive 16 d periods were used, with 10 d for adaptation. Forage ruminal DM disappearance was measured using Dacron bags. Ruminal fluid was sampled on d 14 of each period to …

Program Feeding Strategies for Reducing Costs of Wintering Beef Cows
… was weighed and sampled to measure nutrient output. Program feeding corn-based diets at similar energy intakes to ad libitum hay diets improved animal performance (P < .01) and reduced fecal output (P < .02) through increased diet digestibility (P < .01). Program feeding a 50% diet improved …

Intake, digestion site, extent of digestion and digesta kinetics in grazing lactating cows
… and CoEDTA), used to estimate duodenal flow, fecal output, and ruminal turnover, were administered through the rumen cannula twice daily at 1100 and 2300 h. The supplemented cows had greater milk production (23.7 kg/d) than those on pasture only (19.5 kg/d) with an increase of .66 kg of milk …

The interaction of dietary phosphorus and exogenous phytase concentrations on nutrient metabolism of beef cattle
… above the requirement of the animal, endogenous fecal P and feed P excretion may also increase (Braithwaite et al., 1985; Scott et al., 1985; Ternouth, 1989), contributing to P pollution of surface water (U.S. EPA, 1996). Reducing P excreted in manure would help mitigate the impact beef cattle …

Effects of algal docosahexaenoic acid in an extruded cat diet on nutrient digestibility, fecal characteristics and metabolites, and blood coagulation parameters and fatty acid profiles of plasma and red blood cell membranes
… red blood cell fatty acid profiles. A 4-d total fecal collection was performed at the end of the experimental period for determination of ATTD of macronutrients and fecal score. All diets were well-accepted by the cats and there were no differences (P > 0.05) in food intake among treatments. …
