- Abstract:
- ... The objective of this study was to treat feedlot runoff by developing an ecologically sustainable, affordable, and resilient treatment system having a relatively long life span. Three horizontal flow soil biofilters were utilized in this study: 1) without earthworms and plants (Biofilter (BF)), 2) with earthworms only (Vermifilter (VF)), and 3) with earthworms and plants (Macrophyte Assisted Vermi ...

- Abstract:
- ... Modern molecular techniques enable characterization of the microbial biome in livestock manure, from which there is particular concern over emission of greenhouse gases. This study evaluated how sampling depth, time, temperature, and artificial rainfall affected microbial community structure in feedyard manure, and relationships between the manure biome and known parameters related to nitrous oxid ...

- Abstract:
- ... Antibiotics used during animal production are the same or very similar to antibiotics used by humans. Tylosin, structurally similar to erythromycin prescribed to humans, is a common livestock antibiotic. Therefore, tylosin and other similar antibiotics present a potential threat of environmental buildup resulting in increased microbial resistance. To mitigate this potential impact, a remediation m ...

- Abstract:
- ... Although biochars made in laboratory seem to remove H₂S and odorous compounds effectively, very few studies are available for commercial biochars. This study evaluated the efficacy of a commercial biochar (CBC) for removing H₂S and odorous volatile organic compounds (VOCs). We found that the well-known Ergun equation may not be adequate in predicting pressure drop for properly sizing a ventilation ...

- Abstract:
- ... Tylosin, an antibiotic used for maintaining livestock health, is a macrolide structurally similar to a number of important, often prescribed human antibiotics. Because of this relationship, tylosin presents a potential threat of antimicrobial resistance from environmental buildup. This work investigated tylosin sorption to natural diatomaceous earth product (DE) and the types of physical interacti ...

- Abstract:
- ... Manure is commonly used as a fertilizer or soil conditioner; however, land application of untreated manure may introduce pathogens and antibiotic‐resistant bacteria (ARB) into the soil, with harmful implications for public health. Composting is a manure management practice wherein a carbon‐rich bulking agent, such as corn (Zea mays L.) stalk residue, is added to manure to achieve desirable carbon/ ...

- Abstract:
- ... Beef feedyards produce nitrous oxide (N2O), a potent greenhouse gas. Limited research has evaluated the processes that produce feedyard N2O, and how rainfall and temperature impact N2O losses. Manure in feedyard pens develops into a complex ecosystem of microbes, extracellular enzymes, feces and urine, and varying H2O content. This study aimed to improve understanding of feedyard N cycling under d ...

- Abstract:
- ... Concerns exist that beef cattle manure amendment may increase antimicrobial resistance (AMR) in cropland soils and persist over time, potentially increasing food‐animal and human exposure via feed and produce. Manure and soil contain many types of antibiotic‐resistant bacteria. However, zoonotic pathogens and fecal indicators are most directly linked to human disease and environmental surveillance ...

Nine biochars made from pyrolyzing poultry litter, swine manure, oak, and coconut shell at 350 °C and 500 °C and a commercial coconut-shell activated carbon were evaluated for their sorption capacities toward the odorous compounds. These ...

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions. First-order decay rates were determined for each antibiotic with half-lives ranging from 1day (chlortetracycline) to 10days (tylosin). ARGs were monitored in the swine manure slurry, and ...

- Abstract:
- ... A variety of portable wind tunnels and flux chambers have been used to measure fluxes of volatile organic compounds (VOC) and ammonia (NH3) at animal feeding operations (AFO). However, there has been little regard to the extreme variation and potential inaccuracies caused by air velocity or sweep air flow rates that are either too low or too high to simulate field conditions. There is a need for c ...

- Abstract:
- ... Swine manure is often applied to crop land as a fertilizer source. Odor emissions from land-applied swine manure may pose a nuisance to downwind populations if manure is not applied with sufficient forethought. A research project was conducted to assess the time decay of odorous volatile organic compound (VOC) emissions following land application of swine manure. Three land application methods wer ...
