control – Swine in Minnesota

Best of Leman 2022: Paul Yeske – Recirculation of M. hyopneumoniae in previously immune animals

This is our most popular series on the blog. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

You can find all of the presentations selected from previous conferences on the blog here.

The 2023 Allen D. Leman swine conference is less than a month away. Register here!

Focusing on the grow/finish stages of production to better control PRRS, the new challenge of the swine industry?

Should we redirect our research efforts to focus on PRRS prevention and control in growing and finishing pigs? This was the call for action made by Dr. Montse Torremorell, Associate Professor at the University of Minnesota when she opened the special session “Grow/finish phase of production: What are we learning and implications for making progress on PRRS control.” sponsored by Boehringer Ingelheim during the North American PRRS Symposium this past weekend in Chicago. Torremorell argued that if the swine industry wants to advance regional PRRS control, more emphasis needs to put on preventing and controlling PRRS in growing pigs.

Effect of intervention practices to control the porcine epidemic diarrhea (PED) outbreak during the first epidemic year (2013-2014) on time to absence of clinical signs and the number of dead piglets per sow in Japan

This week, the MSHMP team shares their summary of a publication on the intervention practices put in place in Japanese herds to control Porcine Epidemic Diarrhea.

Key Points

There was little to no research on factors affecting time to absence of clinical signs (TAC) and dead piglets/sow (DP/S) during PED infections.
Good external biosecurity in the form of clean transport methods and one-way truck entrances is significantly associated with lower TAC and DP/S.
The timing of feedback relative to the PED outbreak was more important than the method of feedback.

Controlling Mycoplasma hyopneumoniae infections in the field

Controlling Mycoplasma hyopneumoniae in the field can be challenging. After summarizing the best sample types and diagnostic methods to detect mycoplasma infections early, Dr. Maria Pieters wrote an article for pig333 recapitulating the existing options for a producer struggling with enzootic pneumonia on her farm.

No single strategy will confer total protection. A well-orchestrated combination of various methods adjusted to a single production unit or system will be needed.

Indeed, Dr. Pieters reminds us that 3 different approaches can be combined to achieve greater disease control:

overall-mycoplasma-hyopneumoniae-control-is-effectively-achieved-when-combining-various-strategies_126971.jpg No single strategy will confer total protection from infection with M. hyopneumoniae or disease elimination. However, a well-orchestrated combination of various methods, not only directed at clinical signs, but to the root of disease spread and transmission, adjusted to the unique characteristics of a production unit or system, is necessary to reach the goal of controlling M. hyopneumoniae infections and improving overall swine production around the world.
