Around the "Horns"

Mortality Management. University of Nebraska research is looking at whether composting pig carcasses or raising pH of manure with lime can help control porcine epidemic diarrhea virus (PEDv). Composting, when done properly, will result in temperatures that exceed those required to kill pathogens and this was confirmed in this research. Using lime to bring the pH of manure above 10 also eliminated the virus.  More...   Related: Waste to Worth proceedings paper

  • Topdressing pig manure on what crops in early spring has been researched in Ohio for several years with encouraging results. Timing is crucial to balance crop nutrient uptake with avoiding compaction of soil. More... | Related: Archived webinar (2014) on this research "Making Maximum Use of Nutrients In Liquid Manure"
  • Legacy nitrogen in the Mississippi Valley River Basin was the topic of an article published in the journal Environmental Research Letters. The research used a mass balance approach and used soil data to identify a large accumulation in the lower layers of soil, representing a nitrogen poll that is likely to continue moving into water sources for decades - even if all new fertilizer applications were stopped immediately. News release... | Journal Article
  • A review article published in the journal Animal Feed Science and Technology looked at reducing crude protein and fiber inclusion in pig diets and the effects on gut health and the environment. They concluded that reducing crude protein is an effective strategy to reduce negative environmental impacts and that fiber inclusion can improve gut health. More...
