Cold Plasma Technology to Clean Swine Barn Air

Reprinted as posted on Swine in Minnesota blog.

Porcine reproductive and respiratory syndrome virus (PRRSv) costs the US swine industry more than $580 million each year. First described in North Carolina, Iowa and Minnesota in the late 1980s, the virus rapidly spreads through swine barns and is one of the industry's biggest game changers. Additionally, pigs infected with virulent strains exhales aerosols containing a large quantity of the virus.

Today, researchers in the Veterinary Diagnostic Lab at the CVM are looking to apply research they are doing on decontaminating foods in collaboration with the University of Minnesota College of Science and Engineering (CSE) to swine barn air filtration in an effort to further promote swine health and safety in the food industry at large.

Corn DDGS is a High-Value Feed Ingredient for Swine: Part 7

By Dr. Jerry Shurson, University of Minnesota Department of Animal Science © 2018 Feedstuffs. Reprinted with permission from Vol. 90, No. 12, December 3, 2018

The fatty acid composition of dried distillers grains plus solubles (DDGS) is important for several reasons, including its contribution to metabolizable and net energy content, effects on pork fat firmness in growing/ finishing pigs and susceptibility to lipid oxidation during production, transport and storage.

As shown in Table 1, the major fatty acids present in DDGS corn oil are linoleic acid (54%), oleic acid (26%) and palmitic acid (14%). Linoleic and oleic acids are unsaturated fatty acids that contribute to the high-energy content of DDGS but also cause the oil in DDGS to be susceptible to oxidation. Linoleic acid is the primary contributor to soft pork fat when feeding DDGS to growing/finishing pigs. The fatty acid profile does not appreciably differ between high-oil (greater than 10% crude fat) and reduced-oil (less than…

Register for 2019 PorkBridge & SowBridge Programs

Don't have a lot of time to attend a seminar or conference, but are still interested in staying current with new research and management techniques in the pork industry? PorkBridge and SowBridge programs allow owners, managers and employees to increase their knowledge and skills without needing to leave the comfort of their home or farm office. Both programs are distant education programs combining a presentation viewed on a computer with live presentations delivered by teleconference from topic experts at a scheduled time or via a recording if unable to participate during a scheduled time.

The difference in the two programs is the audience they are aimed at.

MN Pork Congress - February 5-6

Be sure to visit the University of Minnesota's swine group booth at MN Pork Congress February 5 - 6. MN Pork Congress is an annual event sponsored by the Minnesota Pork Producers Association and held at the Minneapolis Convention Center. A number of seminars are held throughout the 2-day event.

Additionally, while at MN Pork Congress, stop by the U of MN booth to visit with individuals from the University of Minnesota swine group about current research and other swine related happenings at the college.

The Biosecure Entry Education Trailer (BEET) unit will be on display. Stop by to see how it can be utilized to educate employees and others about biosecurity.

Contact the MN Pork Producers Association for more information about attending MN Pork Congress at (507) 345-8814 or
