Manure management practices recycle nutrients in animal manures for crop production. Harmful microbes and viruses in the manure are generally reduced in the soil environment over time. The soil properties influencing how long animal virus persistence are poorly understood and may be specific even down to the type of microbe present. …
Manure Treatment and Natural Inactivation of Porcine Epidemic Diarrhea Virus in Soils
Proceedings Home | W2W Home 
Purpose
The porcine epidemic diarrhea virus (PEDv) outbreak in North America has substantially impacted swine production, causing nearly 100% mortality in infected newborn piglets. Because manure may remain a source of reinfection, proper manure management practices to limit outbreaks need to be developed and evaluated.…
PEDV Survivability in Swine Mortality Compost Piles
*Purpose
PEDv has caused significant losses in the Nebraska pork industry and mortality can approach 100%. Disposal of these carcasses is a challenge as they serve as a source of tremendous amounts of infectious virus. Current alternative methods of disposal include rendering, incineration and burial.…
Time-Temperature Combinations for Destruction of PEDv During Composting
*Purpose
The purpose of this project was to determine the appropriate time-temperature combinations required for inactivation of the porcine epidemic diarrhea virus (PEDv) in composting material as a basis for evaluation of composting for disposal of swine mortalities and/or other PEDv-positive biological material.…
Biosecurity for Livestock and Poultry Manure Management
Most biosecurity plans are meant to protect animal and human health by preventing the spread of bacteria or other pathogens. Indirectly, effective biosecurity practices can reduce the likelihood of multiple or catastrophic mortalities which is an issue of environmental concern. While not usually discussed under the umbrella of “biosecurity”, manure handling should not be ignored when considering your plan.…
Managing Biosecurity to Control Porcine Epidemic Diarrhea virus (PEDv)
The appearance of the Porcine Epidemic Diarrhea Virus (PED) in North America presents significant challenges for manure applicators. Since the virus is primarily spread by fecal-oral contact and can survive in manure for extended periods of time, it is possible for the disease to be spread by any object that becomes contaminated with infected pig manure.…
