Agricultural Research Service (ARS) scientist Scott Yates recently
discovered oxytetracycline (OTC), an antibiotic that is administered to
animals, breaks down more quickly in cattle manure than it does in soil.
Yates, who works at the ARS Contaminant Fate and Transport Research Unit
in Riverside, CA, found that in controlled laboratory conditions, OTC in
cattle manure was degraded more quickly as temperatures and moisture
content in the manure increased. However, the OTC breakdown slowed as
water saturation levels neared 100%. Yates concluded that this slowdown
resulted when oxygen levels were not high enough to fuel the OTC
biodegradation.

Now’s the Time to incorporate a Slurrystore System into your nutrient
management program. Slurrystore is compatible for any system whether
your goal is long term storage, nutrient retention, green containment,
digesters or manure processing. Plus Slurrystore Systems include the
added feature of agitation to help ensure nutrient consistency. Click here or contact your local
Authorized Slurrystore Dealer for more information.

Researchers at the University of Missouri (MU) Center for
Agroforestry suggest that buffer strips of grasses and other plants can
trap and break down veterinary antibiotics in manure used as fertilizer.
Buffer strips have already demonstrated that they can be effective in
protecting water quality, controlling erosion and supporting wildlife
around crop fields. “Vegetative buffers already are a recommended
practice for reducing sediment, nutrients and herbicides in surface
runoff. Our research is showing another benefit,” says Keith Goyne,
assistant professor of environmental soil chemistry in the MU School of
Natural Resources.

North Carolina pork producers have until April 15 to submit
proposals indicating their interest in helping supply waste-generated
power for the state.
Proposals will be submitted to North Carolina electric suppliers as part
of a state requirement mandating that power companies must use swine
waste to produce electricity. A request for proposals (RFP) process
signals the energy buyers are seeking proposals for energy and/or
renewable energy certificates. Each buyer will determine whether or not
it will enter into a contract with a respondent based on the proposal.

Kansas State University (KSU) experts say spring is a good time for
producers to clean cattle feedlots or areas where manure accumulates. If
not properly cleaned and maintained, confined feeding pens and temporary
feeding sites for wintering cows or winter-backgrounding calves are
prime contributors to odor emissions, according to Joel DeRouchey, KSU
animal scientist.
Fly production from those sites is also much greater when manure and
wasted feed are present. In addition to creating a nuisance, the
potential exists for reduced animal performance during the summer, he
says. Visit the KSU cattle management website at www.asi.k-state.edu/.

The Wisconsin Department of Nature Resources (DNR) offers a web page
devoted to providing resources to help producers prevent manure runoff
events. The site provides video clips and links to additional
information. Visit the site at dnr.wi.gov/runoff/ag/manure.html.
The eXtension Livestock and Poultry Environmental Learning Center
recently launched a YouTube channel in order to offer video clips
illustrating helpful nutrient management information. The initial
offerings include a manure safety video
and antibiotic
and hormone basics /.
Another YouTube effort, provided by Oklahoma State University’s Waste
Management Channel, depicts several technologies at work on operating
livestock or poultry farms throughout the southern United States. The
channel features videos devoted to a weeping wall, mechanical solid
separator and litter baler. Visit the site at www.youtube.com/user/
