What's Going On In the LPELC?

Waste to Worth: Spreading science and solutions logoWaste to Worth. The call for abstracts has been extended until November 17. Registration will open October 15.  This is a great opportunity to showcase your research, extension, and education projects on animal ag and stewardship!  The conference is also looking for vendors and sponsors. Waste to Worth will be held in beautiful downtown Seattle within walking distance of the Space Needle, Waterfront, and public transit.

Cattle & Climate. The Southwest region climate team is sponsoring a "Cattle and Climate" workshop on November 6, 2014 in Stillwater, OK. More... The workshop is free, but an RSVP is needed to attend.

Climate Conference. The Northeast region climate team is hosting a dairy systems climate adaptation conference on July 29-31, 2015 in Ithaca, New York. The call for papers is out. The conference will feature many exciting tours and showcase state-of-the-art manure handling and housing. More...

Biogas Roadmap, Nutrients & Water, Animal Mortalities

Biogas Roadmap. The USDA, US EPA, and US Department of Energy have released a joint report "Biogas Opportunities Roadmap" which looks at things like potential, barriers, opportunities, and solutions. The reports focuses on voluntary actions to increase biogas production. More... | Related: Introduction to Biogas and Anaerobic Digestion

The Great Lakes Restoration Initiative announced the release of a its second five-year action plan. One of the major focus areas for the plan is the reduction of nutrients entering the lakes. More... | The US EPA Inspector General's office released a report titled "US EPA needs to work with states to develop strategies for monitoring the impact of state activities on the Gulf of Mexico hypoxic zone. Whew! That is a mouthful. This report details shortcomings and suggests fixes in the endeavor to reduce the Gulf "dead zone". More... | Related: manure nutrient management

bottles of veterinary pharmaceuticalsAntibiotic Resistance.

  • The White House recently issued an executive order on combating antibiotic-resistant bacteria. Not surprisingly, agriculture figures prominently in the order. More...
  • We have reported previously on research that indicated antibiotic-resistant bacteria were present in the noses of workers on conventional hog farms, but not on antibiotic-free farms. Some of the same authors have followed up to look at how long it takes for those bacteria to clear out of the system of a farm workers after leaving the farm. It took as long as four days. More...
  • In the "huh?, what?" department, a study recently published in the Proceedings of the National Academy of Sciences (PNAS) shows that manure from cows NOT treated with antibiotics caused a proliferation of antibiotic resistant bacteria in soils. It will be interesting to see what follow-up research (if any) shows. More...

Dung Beetles. A recently announced research project will study whether dung beetles can suppress pathogens in soil. Dung beetles are already well known to be a natural clean-up crew when it comes to manure. Now, we will learn whether they can lend a hand in food safety as well. More... 

Manure Odor. The science surrounding odor has always suggested it is a complex interaction of tens, or perhaps even hundreds, of chemicals. USDA Agricultural Research Service (ARS) scientists looked to identify compounds responsible for beef cattle manure odor. They also examined how diet, soil moisture, and land application practices affected odors. They found that three compounds were responsible for around 2/3 of the odor in beef manure.  More...Related: air quality in animal agriculture

Animal Welfare.

  • A fascinating survey of farmers and non-farmers found significant differences in the perceptions of the welfare of beef cattle. More...
  • If you have been following the California battery cage law and attempts by other states to prevent it from being enacted, it appears this saga is finally over. The law will be enacted as written. More...

goatGoats & Weeds. The use of goats as a weed control strategy has been studied before, but it certainly bears repeating. Goats can be more effective than chemical herbicides at combating an east coast marsh weed. More...

Litter Timing. Timing is everything and a USDA ARS study suggests that litter application in the spring is more advantageous than in the fall. The study was conducted in the deep South. More...

Biochar. A Rice University study attempts to explain why biochar (which can be produced from many things including manure) improves soil quality. Especially notable is how biochar has been shown to improve the water-holding ability of sandy soils and the drainage of clay soils. More...

Feed & PEDv. Recent reports (More...) indicated that it was possible to carry the Porcine Epidemic Diarrhea (PED) virus in feed ingredients. The International Feed Industry Federation responded by emphasizing that feed ingredients were not a source as long as proper manufacturing and biosecurity protocols are followed. More... Editor's note: The emphasis on "carry" and "source" were intentional as these are two different things. Biosecurity continues to be critical in preventing the spread of PEDv and any equipment that might carry small amounts of feed (as well as manure) needs to be thoroughly cleaned before moving to a new site or building. However, feed straight from the manufacturer (who observes manufacturing and biosecurity protocols) is now confirmed to be an unlikely way to introduce the virus onto a farm.
