Recently the UMN MycoLab published a paper in the Veterinary Microbiology journal where they investigated how two different gilt flow managements during acclimation impact Mycoplasma detection. Highlights of the research included: Two strategies were evaluated for Mycoplasma hyopneumoniae gilt acclimation. M. hyopneumoniae detection and seroconversion were assessed in gilts over time. Similar M. hyopneumoniae seroconversion was similar regardless of gilt flow. Genetic variability of M. hyopneumoniae was not significant in gilts. The full publication is available on the journal’s website .

The excessive amount of ice and snow that has fallen this winter has livestock owners concerned about snow load and potential roof collapse. The design roof snow load for residential buildings in MN is set by state statutes and is 42 pounds per square foot (psf) in northern MN and 35 psf in southern MN. However, many agricultural buildings are built using a 20 psf snow load which would be expected to handle six feet of dry, fluffy snow or one foot of wet, heavy snow.

The Upper Midwest Agricultural Safety and Health Center (UMASH) has a new video for those working with pigs and protecting them from getting injured on the job. Farm Worker Sow Behavior Safety Tips video was created in collaboration with Diane DeWitte, UMN Extension swine educator, Colin Yoder, UMN Veterinary Public Health resident, and Hayford Manu, UMN researcher. The video incorporates expert and industry advice to address sow behavior and management techniques to handle the animals safely. The video is available in English and Spanish. Two additional videos can be used as training materials for new employees or as a refresher for existing workers. Those videos are Protecting People and Pigs from the Flu and Moving Sows: Be Safe and Smart. These two videos are also available in both English and Spanish. Watch these video resources.

The UMN Swine Disease Eradication Center has a new podcast called “Processing the Litter-ature”. A podcast where peer-reviewed papers are docked, clipped and supplemented with a field perspective. In the first episode, Dr. Carissa Odland and Dr. Peter Davies discuss their paper “Evaluation of the Impact of Antimicrobial Use Protocols in Porcine Reproductive and Respiratory Syndrome Virus - Infected Swine on Phenotypic Antimicrobial Resistance Patterns.” Listen to the podcast. In the second episode, Dr. Matt Sturos and Dr. Deb Murray discuss “Persistence and shedding of senecavairus A in naturally infected boars”. Listen to the podcast.

By Diane DeWitte, UMN Extension Swine Educator Originally printed in The LAND - as January 6, 2023 Swine & U column This winter of 2022-2023 has already provided a wide array of thrills and chills! Keeping the driveways clear, the water flowing, the power & heat on, and the pigs safe and fed is a daily challenge during Minnesota’s winters. Our friends at the Upper Midwest Agricultural Safety & Health (UMASH) center offer this discussion about the dangers of cold weather outside work. WORKING OUTDOORS Cold temperatures pose serious threats to a person’s health, leading to frostbite, hypothermia, or trench foot, which occurs when the feet have been exposed to water for too long. Symptoms of hypothermia may include lack of coordination, confusion, slurring, drowsiness, or slowed breathing. Signs of frostbite and trench foot include skin that is numb, swollen, firm, blistered, red, or gray. UMASH SAFETY CHECKLIST Can you complete indoor tasks and leave outdoor tasks for a wa

By Diane DeWitte, UMN Extension Swine Educator Originally printed in The LAND - as February 17, 2023 Swine & U column The University of Minnesota has Animal Science faculty that have successfully studied group sow housing, organic pigs and alternative swine production for several years. Readers here are familiar with Dr. Yuzhi Li’s work at UMN’s West Central Research & Outreach Center (WCROC) conducting university-based, peer-reviewed studies of organic pig farming. Dr. Li and Dr. Lee Johnston, both UMN Department of Animal Science faculty, have spent more than a decade developing projects which have measured how well pigs raised in non-traditional or alternative production systems grow, take care of their piglets, and survive. Dr. Li, Dr. Johnston, and a varied team of faculty from agronomy, economics, nutrient management and Extension are currently eighteen months into a complex study of organic hybrid rye grown for feed and bedding of organic pigs raised at WCROC.
