Webcast Series

Looking Ahead to December: Pathogens 101: Manure and Veterinary Pathogens of Concern

This webinar will provide an overview of bacteria, viruses, and parasites found in manure and other land-applied wastes as well as pathogens of veterinary concern. What are these pathogens? How do they affect you? What are their typical levels in manure and wastes? The presenters will also discuss veterinary concerns, and overall prevalence in the environment. This webcast will be valuable to those who work with animal agriculture to converse with those outside of agriculture and to provide information that can be used in training programs. More... December 16, 2016 at 1:30 p.m. (central); 2:30 (eastern); 12:30 (mountain);11:30 am (pacific).

Around the Horns

Antibiotic Resistance. The United Nations Food and Agriculture Organization has released a new report "Drivers, Dynamics, and Epidemiology of Antimicrobial Resistance in Animal Production". The report strongly supports more research into this area as well as phasing out the growth promoting use of antibiotics. News release... | Download the report...

Farmer Stewardship. Several dairy farmers in Wisconsin hosted tours showing how they use cover crops to help manage manure. More... The first in a series of articles about the tours focused on the Livestock Water Recycling system in use at the Robinway Dairy. More...

Grazing Management.

  • A multi-state research project will examine the impacts of livestock grazing cover crops on soil health, animal health, and crop yields.  Read more... | Visit project website (in beta)
  • British research examined the impact of dung beetles on cattle parasites around dung pats in pastures. News release... | Journal article...
  • USDA NRCS will be hosting a webinar on "Using Adaptive Grazing to Improve Soil Health in Grazing Ecosystems". The webinar will be January 10, 2017. Learn more...
  • The Pennsylvania State University Dairy Team is hosting a series of webinars "Grazing Guides for Dairy Systems". The first webinar will be December 14, 2016 on the topic of weed identification. Learn more about the series...

Air Quality. Research from Colorado State University links ammonia emissions from Arctic bird guano to the formation or aerosol particles that can help keep the area cool. (Jill's note: I know this is not directly related to animal agriculture, but it seemed relevant to consider as we talk about ammonia emissions from poultry and other animal agriculture.)  Read more... | View the journal article

Farm Systems.

  • A new multi-institutional research project will examine integrating organic livestock with crop production. Most organic livestock producers rely on off-farm feed purchases. The project will examine different crop rotations for their overall value as cash crops as well as grazed.  More...
  • The Sustainable Agriculture Research and Education (SARE) program has released a guide, "Systems Research for Agriculture". The guide explores multi-faceted research and how to develop teams and design and manage systems experiments. The guide is free as a PDF download (96 pages) or a print copy ordered for $20.
  • Americans waste a great deal of food, as much as 40% by some estimates. Using food waste for livestock is one way to reduce the environmental impacts of that waste stream. "Leftovers for Livestock: A Legal Guide for Using Excess Food as Livestock Feed" is a joint publication of the Harvard Food Law and Policy Clinic and the University of Arkansas Food Recovery Project. Read the blog post... | Download the guide... (PDF 66 pages)

Nutrient Management.

  • Sidedressing manure is boosting profits for an Ohio farmer. Read more... | Related: Archived webinars on the long-term on-farm research that led to this story, "Making Maximum Use of Nutrients in Liquid Manure" (2014) and "Utilizing Liquid Livestock Manure as a Topdress to Wheat and Sidedress to Corn" (2011)
  • North Dakota State University has released the most recent Livestock Environmental Management newsletter. This issue includes information on bale grazing, manure nitrogen on wheat, the phosphorus index and more. Read the newsletter...
  • An Ohio State University study looked at farm practices that can reduce nutrients, especially phosphorus, entering water and causing harmful algal blooms. They also looked at rates of adoption by farmers and the willingness of the public to finance those practices. Overall, they found that public support was likely not enough to meet nutrient reduction goals, but that knowing about this potential funding gap could encourage new ideas and innovations.

Water Quality

  • The University of Illinois has released a new publication "Ten Ways to Reduce Nitrogen Loads on Tile Drained Crop Lands in the Midwest". This publication does not focus on manure, but the information is applicable to all nitrogen sources, including manure. See description... | Download PDF (48 pages) | Related: "Preferential Flow of Manure in Tile Drainage" includes information on manure application and a links to archived webinars and Waste to Worth proceedings.
  • Oklahoma State University released the latest issue of "Poultry Practices", a newsletter focused on poultry manure management. This issue discusses phosphorus application strategy research, controlling pathogens on antibiotic-free farms, and mass mortality composting. Read the newsletter...
  • A new EPA assessment found that four out of every 10 lakes has too much nitrogen and phosphorus. This report is based on the data gathered in the last round of sampling (2012). News release... | Download the report...

Safety & Health.

  • Several county officials, among others, gathered to discuss manure hauling safety and ways to reduce damage to roads. More... | Related: A collaborative project in the Upper Midwest conducted research on road damage from manure hauling
  • In a followup to a previous study that identified the presence of antibiotic resistant bacteria in the noses of hog farm workers, Johns Hopkins University has begun following up to determine if there are health impacts to the carriers. In a small study of 103 workers, they found that a small percentage of those workers and their children developed skin infections consistent with staph infections. More...

  • Digesters are gaining traction as a technology to help farms reduce their environmental impact. However, they are a better fit in some situations than others. This article includes information from University of Wisconsin Extension Specialists on "What Manure Digesters Can and Cannot Do". Wisconsin public radio also produced an audio interview. Listen to the audio...
