Metabolism of halofuginone in rats and sheep fed excreta from poultry administered halofuginone orally
… wether lambs consuming a silage composed of 60% excreta, 20% ground hay, 10% ground corn and 10% dry molasses. The feces contained detectable levels of the drug. Sheep were slaughtered after a 16 d accumulation period. None of the analyzed tissues except the eyes contained halofuginone. When the …

Closing the loop: Assessing the viability and environmental risks of human excreta-derived fertilizers in sustainable food systems
… to synthetic fertilizers is the use of human excreta. Human excreta is usually considered a waste product and is often dumped in the environment without treatment, causing unsafe sanitation and contamination of drinking water. The reframing of human excreta as a resource, rather than a waste …

The Determination of Oxytetracycline Levels in Soft Tissue, Bone, Blood, and Excreta of Patients Suffering From Malignant Cancer
In 1950 Finlay et al. isolated from soil a new actinomycete, Streptomyces rimosus. which was found to produce an antibiotic substance. This substance, which they named terramycin, showed an Inhibitory action against gram-positive cocci, gram-negative enteric organisms, and aerobic spore-forming …

Quantifying Greenhouse Gas Emissions and Ammonia Volatilization from Soil Amended with Excreta from Ruminants Fed Alternative Forage-based Diets
… and reduce gas emissions from soil receiving excreta. The objective of the study was to determine if soil receiving urine or manure from sheep fed forage diets supplemented with condensed tannin or polyphenolic-containing legumes would decrease N gas emissions. Two field trials were conducted: …

Application of Ecological Sanitation Approach in Excreta Waste Management Among the Local Community: A Case Study of Hananasif Ward, Kinondoni Municipal
Conventional sanitation technologies based on pit lavatories and flush toilets cannot solve the problem of waste water managements in urban setting which mostly comprises with poor water systems infrastructures. Therefore this study aimed to assess the extent of application and acceptability for …

Phosphorus bioavailability and digestibility in soybean meal, spray dried plasma protein and meat and bone meal determined by different methods in poultry
… the effects of increasing P intakes on excreta P retention values using corn and corn supplemented with increasing amounts of KH2PO4 to provide total P intakes of 51-351 mg. The results indicated that excreta P retention values decreased when non-phytate P intakes were 76 mg or higher. …

Methodology for evaluating the digestibility and metabolizable energy of poultry feedstuffs
… is the procedure employed in the drying of excreta samples. During sample preparation, substantial grinding losses were incurred amounting to 3.5 to 5.2% of the dried sample weight. Also moisture uptake during sample grinding accounted for a 1.9 to 3.9% increase in sample weight. To properly …

Effects of Feeding Phytase Enzyme and HAP Corn on Solubility of Phosphorus, Copper, and Zinc in Turkey Manure and Manure-Amended Soils
… manure P extracted with 0.01 M CaCl₂ from fresh excreta (P < 0.05). Soils amended with wet NPA+Phyt, HAP, and HAP+Phyt manures released 29 to 49% more water-soluble P than soils amended with NPA+P manure on an equal-P basis (P < 0.05). Feeding the NPA+Phyt diet instead of the NPA+P diet did not …

Effect of particle size on nutritional value of soybean meal for poultry
… (AMEn), ileal phosphorus (P) digestibility, excreta P retention, gizzard weight, and standardized amino acid digestibility were determined using a 21 d broiler chick assay. Four corn-SBM diets that only differed in the mean particle size (466, 809, 1,174, or 1,577 μm) of the SBM were fed from …

Evaluation of the nutritional values of seven insect meals for inclusion in poultry diets
… 7 aimed to determine ileal P digestibility and excreta P retention values for two BSFL samples (BSFL 1 and 3) and partially-defatted BSFL. Three dextrose-cornstarch based diets consisting of 27%, 30%, and 30% of BSFL 1, BSFL 3, and partially-defatted BSFL, respectively, were fed to broiler …

Efficacy and safety of a new genetically modified phytase for improving dietary phosphorus utilization of swine and poultry
… feed consumption were recorded weekly. Fecal and excreta samples were collected for determination of Ca and P digestibility. At the end of all experiments animals were slaughtered, and 10th ribs or right foot for pigs, and both middle toes for turkeys were removed for bone analysis. In pigs …

Experimental manure handling systems for reducing airborne contamination
… system to control the air contamination from the excreta. The goal was to get close to zero air contamination from manure with these systems, in order to measure the contamination from other sources, and to also have a range of contamination levels for future health and productivity testing. Two …
