Batch Farrowing In Large Farms: a podcast

Happy President’s Day to our US-based readers! If you have the chance to stay home and relax today, here is a podcast for you to enjoy!

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

In this episode, Drs. Torremorell, Spronk and Wetzell are hosting Dr. Daryl Olsen, managing partner at AVMC to talk about batch farrowings and how they are coming back even in dense pig production areas.

Understanding whether PRRS viruses in a neighborhood are closely related

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, the MSHMP team is sharing results from a study looking at how related PRRSv ORF5 sequences from a same area are.

Key Points

  • 28 space-time clustering of PRRSv based on producers’ routine molecular surveillance were identified in the course of 2010-2019.
  • Being inside or outside a space-time cluster significantly explains the genetic variability of most, but not all cases.
  • Assessing space, time, and genetic relatedness relationships in PRRSV transmission is complex, and overall trends might miss important case information.

Growing African swine fever virus raises risk considerations

Dr. John Deen fron the University of Minnesota recently wrote a column in the National Hog Farmer about African Swine Fever virus and what the recent reports about virus spread mean for the industry.

Addition of antioxidants controls and delays lipid oxidation, but does not affect growth performance and oxidative status of pigs fed oxidized oils

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, the swine nutrition group from the College of Food, Agricultural, and Natural Resource Sciences at the University of Minnesota share the impact of antioxidants on feed quality and growth performances in pigs.

Key points

  • The addition of synthetic antioxidants can improve lipid stability, but does not completely prevent further oxidation in both fresh (unoxidized) and oxidized lipids.
  • The addition of synthetic antioxidants did not affect growth performance of pigs fed oxidized oil, but improved signs of oxidative stress.

Confused about Streptococcus zooepidemicus?

Dr. Matheus Costa wrote a couple of articles regarding this new swine pathogen for the online information platform Farmscape.

This first one summarizes what is know about the pathogen so far. You may read the article on the website or even listen to Dr. Costa’s interview.

A second article focuses on biosecurity measures that should be implemented to prevent the spread of the pathogen. Again you may read the article or listen to the interview.

Lastly, Dr. Costa published a summary of the cases so far, shared on this blog a few months back and still available if you would like to read it again.
