Reduction and fate of manure pathogens and antimicrobial resistance
Antimicrobial resistance is a complex issue as it is comprised of not only pathogenic bacteria, but also non-pathogens which share genes within complex environmental systems, such as agricultural fields. This webinar describes potential measures to reduce pathogen and antimicrobial resistance in manure as well as potential fate and transport of manure pathogens and antimicrobial resistance following land application of manure. This presentation was originally broadcast on May 17, 2019. More… Continue reading “Reduction and fate of manure pathogens and antimicrobial resistance”
Three Options for Cleaning Barn Exhaust Air
Reducing aerial emissions and improving air quality is a common goal in the livestock and poultry industries. This webinar presents three approaches to reducing aerial emissions from barn exhaust air, using combinations of wet scrubbing, electrostatic precipitation, filtration and enhanced dispersion. This presentation was originally broadcast on March 29, 2019. More… Continue reading “Three Options for Cleaning Barn Exhaust Air”

Separation Technologies for Capturing Nutrients from Manure
Exporting phosphorus and possibly nitrogen from larger livestock operations as well as regions of large livestock populations is often essential for protecting water quality. Solids (and nutrient) separation technologies are an option for concentrating nutrients for export. This webinar introduces three approaches to solids separation that are being applied in commercial settings. This presentation was originally broadcast on January 18, 2019. More… Continue reading “Separation Technologies for Capturing Nutrients from Manure”
