Effects of commercial chilling methods for reducing bacteria on pork carcasses
Previous laboratory studies have demonstrated that snap/blast chilling is known to significantly reduce some bacterial populations on pork surfaces, including Salmonella, Campylobacter, E. coli, and...
Optimization of phosphorus precipitation from swine manure slurries to enhance recovery
Laboratory experiments were conducted using magnesium chloride (MgCl2·6H2O, 64% solution) to force the precipitation of phosphorus and reduce the concentration of soluble phosphorus (PO4 3?) in two...
Management strategies to simultaneously reduce ammonia, nitrous oxide and odour emissions from surface-applied swine manure
Surface-applied swine manure has the potential to generate ammonia (NH3), nitrous oxide (N2O) and odour. Field research was conducted in Prince Edward Island to measure the simultaneous emissions of...
Comparative investigation of sequentially extracted phosphorus fractions in a sandy loam soil and a swine manure
Sequential fractionation is one of the most common methods used to investigate phosphorus (P) forms in soils. The strategy can be used for evaluating bioavailability of soil P and for investigating...
Transformations of soil and manure phosphorus after surface application of manure to field plots
Transfer of phosphorus (P) from surface-applied manures to runoff is an important source of pollution, but few studies have closely monitored P dynamics in manure, soil, and runoff through time. We...
Comparing ammonium ion dissociation constant in swine anaerobic lagoon liquid and deionized water
The dissociation constant of ammonium ion both in deionized water and swine anaerobic lagoon liquid was determined experimentally in a convective emission chamber at three temperatures (15 degrees...
Water quality improvements of wastewater from confined animal feeding operations after advanced treatment
Current trends of animal production concentration and new regulations promote the need for environmentally safe alternatives to land application of liquid manure. These technologies must be able to...
Quantitation of estrogens in ground water and swine lagoon samples using solid-phase extraction, pentafluorobenzyl/trimethylsilyl derivatizations and gas chromatography-negative ion chemical ionization tandem mass spectrometry
A method was developed for the confirmed identification and quantitation of 17(beta)-estradiol, estrone, 17(alpha)-ethynylestradiol and 16(alpha)-hydroxy-17(beta)-estradiol (estriol) in ground water...
Energy requirements for transport and surface application of liquid pig manure in Manitoba, Canada
The objective of this study was to conduct a thorough accounting of energy used to transport liquid pig manure from farm storage to the field and to surface-apply the manure. Energy consumption was...
