The removal of lime from the ash of cow feces
… and low in lime were fed and the milk, urine and feces were analyzed to determine the calcium eliminated. It was in the analysis of the feces-ash that the trouble was experienced that prompted the following investigation.

Antibiotic resistance gene abundance in feces of calves fed pirlimycin-dosed whole milk
… antibiotic exposure on the abundance of ARG in feces of milk-fed calves. Eight female Holstein calves were blocked by age, paired by block, and randomly assigned to pasteurized whole milk (control; n = 4) or milk containing 0.2 mg/L of pirlimycin (treatment; n = 4). Calves were enrolled after …

Hydrothermal gasification of human feces as an alternative means of waste mitigation and hydrogen production
… the hydrothermal liquefaction (HTL) of human feces. The catalyst screening study revealed that NaOH (46.9%) and Raney Ni (41.2%) resulted in the highest H 2 composition, while Ru/AC resulted in the highest reduction in the liquid CODr (97.7%). A catalyst mixture was then studied combining two …

Abundance of Antibiotic Resistance Genes in Feces Following Prophylactic and Therapeutic Intramammary Antibiotic Infusion in Dairy Cattle
… and relative abundance of ARGs in dairy cow feces. For prophylactic treatment using cephapirin benzathine, nineteen end-of-lactation cows were used. Treatment cows (n = 9) received cephapirin benzathine as an intramammary infusion prior to dry-off, and control cows (n =10) received no …

Noninvasive tracking of jaguars (Panthera onca) and co-occurring Neotropical felids in Belize, Central America by genotyping feces and remote camera trapping
The elusive jaguar (Panthera onca) is extremely difficult to study due to its wide-ranging behavior, crepuscular activity peaks and its occurrence in low population densities in often dense forest habitats. Jaguars are also a species of concern, but our ability to provide for their survival is …

Construction and Use of Species-Specific Dna Probes for the Detection, Identification, and Enumeration of Human Colonic Bacteroides Species (Anaerobes, Hybridization, Microecology, Feces)
… and enumerate organisms from colon contents or feces. Consequently, it has been virtually impossible to address questions concerning the effects of host diet, age, or other factors on the species composition of the colonic flora. Studies that involve colonic Bacteroides species are particularly …

Elucidating fecal contamination exposure in low-income countries, the contribution from child feces disposal practices and soil ingestion, and links to child health
… countries, with a focus on young children’s feces as a source of contamination, soil ingestion as an exposure point, and their effects on child health. First, the occurrence, magnitude, and distribution of fecal contamination and enteric pathogens were assessed along multiple transmission …

Development of a 16S rRNA gene sequence as a biomarker specific to the gastrointestinal tract and feces of swine based on suppressive subtractive hybridization
Fecal contamination of water bodies causes environmental issues and human health risks. Swine are a major contributor of fecal inputs to environmental waters due to their importance in American agriculture. Water quality currently is regulated using fecal coliforms, which have natural reservoirs in …

Hydration of Colonic Ingesta and Feces in Horses Fed Large Grain Meals or Treated with Enteral Fluid Therapy, Saline Cathartics and Intravenous Fluid Therapy
Systemic hydration, plasma electrolytes, ingesta and fecal hydration and gastrointestinal passage of cobalt (after CoEDTA administration via nasogastric tube) in horses fed large grain meals or treated with enteral fluid therapy, IV fluid therapy and enteral laxatives were investigated. In the …

Nutrient characterization of swine fecal waste and utilization of these nutrients by swine
Swine feces collected from finishing hogs was fed to 48 crossbred gilts averaging 125 kg in two total collection metabolism trials. Unprocessed feces (fresh) was used in one trial and dried feces was used in the other trial. Feces from the gilts fed the feces substituted rations were significantly …

Factors affecting estrogen excretion in dairy heifers
… study was to quantify estrogenic activity in feces and urine during the estrous cycle. Ten non-pregnant Holstein heifers were fed the same diet for 28 d. Plasma, feces, and urine samples were collected daily. Plasma 17-β estradiol (17-β E2) was quantified with RIA and used to confirm day of …

Characterization of indigestible fiber in diets based on corn and soybean meal or corn, soybean meal, and distiller dried grains with solubles and in feces from pigs fed these diets
… dried grains with solubles (DDGS), as well as in feces from pigs fed these diets. The in-vitro disappearance of DM without and with inclusion of exogenous enzymes in both diets was also determined. In Exp. 1, total NSP and dietary fiber in diets based on corn and SBM or corn, SBM, and DDGS and in …

Are black bears (Ursus americanus) effective seed dispersal agents? With a little help from their friends.
… fecal piles, but if any seeds are removed from feces by rodents, it is often considered seed predation. In theory, removal of seeds from bear feces by seed-caching rodents could represent a second phase of dispersal that benefits fleshy-fruited plants, yet this idea has never been tested. I …

The Impact of Nutrient Loading from Canada Geese (Branta canadensis) on Water Quality, a Mesocosm Approach
… the impact of Canada Goose (Branta cana.densis) feces on water quality parameters. After 30 days of fecal additions (treatments of 2.419 g, 1.209 g and 12.090 g every 3 d) we found no significant impact on soluble reactive phosphorus, total phosphorus, ammonia, nitrate, total Kjeldahl nitrogen, …

Metabolism of halofuginone in rats and sheep fed excreta from poultry administered halofuginone orally
… uCi or 53.8% of the administered dose in the feces. The urinary output accounted for .157 uCi or 13.7% of intake. The rats respired 1.5% of the administered 14 C. Level of radioactivity in the tissues after the accumulation period was not significantly different from that found in control …

Excretion of Antibiotic Resistance Genes by Dairy Calves
… antibiotic resistance genes (ARG) in the feces. Calves were blocked by breed, gender, and birth order, and assigned to one of three treatments at birth. Treatments were control (containing no antibiotics in the milk replacer), subtherapeutic (neomycin sulfate and oxytetracycline …

Composition and in vivo and in vitro digestibility of cattle fecal waste
… for dry matter and 66% for crude protein. The feces collected during this trial were dried in a forced air oven at 120 C and ground. The chemical composition of the feces was 13.2% crude protein, 31.4% crude fiber, 2.8% ether extract, 5.4% ash, 38.8% NFE, 70.9% cell walls and 44.8% ADF, dry …

The transmission ecology of Echinococcus multilocularis in a North American urban landscape
… detection of E. multilocularis eggs in coyote feces, sugar fecal flotation showed lower sensitivity than the ZnCl2 centrifugation and sedimentation protocol (0.46 vs. 0.75). The latter technique is therefore recommended for screening of canid hosts. This study provided the first evidence of an …
