DairyCast update for April 8, 2011, What Does NIAA Have In Store For Its Conference?

What are Nanoparticles? They may provide value in dealing with agricultural air emissions.  Researcher Dr. Bernardo Predicala discusses his specific interest in ammonia suppression but suggests the long-term outlook is positive across a range of contaminants.

What does USDA's 'Test and Hold' mean? This new requirement for meat and poultry products will enhance existing procedures and help to reduce foodborne illnesses.

How Does USDA Inspected Stamp Change?

The USDA has issued a change in the way the pervasive "Inspected" stamp is to be applied in the future. The new process calls for the stamp's application to occur after test samples come back negative for any issues.

The American Meat Institute has long urged the industry to adopt test and hold policies. In October 2009, Patrick Boyle, president of AMI, sent a letter to Secretary of Agriculture Tom Vilsack asking that the agency mandate test and hold. Boyle noted in the letter that more than 80 percent of the recalls due to of E. coli O157:H7 and all recalls due to the presence of Listeria monocytogenes during 2009 could have been prevented if tested products had been held.

How Will Radiation Affect Dairy Production?

The US Environmental Protection Agency (EPA) reported that milk products in Spokane, Wash had 0.8 pCi/L of iodine-131, a level 5,000 times lower than the Derived Intervention Level set by the U.S. Food and Drug Administration. It is believed the radiation is from the Japanese Fukushima Daiichi nuclear plant. The EPA continues to with state and local governments on monitoring of milk under its RADNET program.

“Iodine 131 has a half-life of eight days, meaning that every eight days it loses half its strength. Since production of iodine 131 stopped when the Fukushima reactors shut down on March 11, it has already been through two half-lives and could easily be halved once or twice more again before the milk is consumed as cheese or yogurt." the New York Times reported.

Can Dairy Practices Reduce Carbon Footprints?

A study on milk production use of Recombinant Bovine Somatotropin (rbST) showed a reduction in the carbon footprint of dairies. Using rbST to increase milk production in cows means that less cows, resources, and energy are needed produce the same quantity of milk, when compared to a dairy operation not using rbST.

"Environmental sustainability is an important consideration in agricultural production, with emphasis placed upon meeting human food requirements while mitigating environmental impact. The present study demonstrates that use of rbST markedly improves the efficiency of milk production and mitigates environmental parameters, including eutrophication and acidification, greenhouse gas emissions and fossil fuel use," wrote the study’s authors.

Power To The Poultry Manure

Poultry manure, as a by product of poultry production, is getting attention of public groups in the Shenandoah Valley (VA). The big question is what to do with it. As source of energy, manure represents an opportunity. But the approach to generating usable energy can be controversial.

All manure to energy systems offer at least one source of revenue for poultry growers, the purchase of poultry litter to start the process. The large and small scale options differ, however, in several ways: grower contract requirements, from none to a 10 year commitment; the price paid for the litter, from $5 to $15 a ton or more; the grower’s investment, from none to $100,000 or more; and who owns the power generated, electricity, bio-gas or bio-oil, and any other saleable byproducts, such as fertilizer.

The Shenandoah Valley Poultry Litter to Energy Watershed & Air Advisory Group has been meeting to help capture public opinion, develop solutions, and put forth executable approaches.

DairyCast Update for March 25, 2011, Are Air Emissions A Concern?

It's muddy boots time as spring hits full swing.  If your boots aren't muddy, you must be in Texas where drought is threatening to break a decades long record of dryness. 

We're thinking Washington this week as farm bill discussions continue.  ProFarmer's Jim Wiesemeyer shares his outlook on macro factors affecting agriculture.  Also some exciting news in nanoparticle technology as it relates to air quality in livestock operations.
