Farm data analysis for lifetime performance components of sows and their predictors in breeding herds

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.

For our US-based audience, we hope that you had a great Thanksgiving despite the circumstances. We are grateful for the ever-growing readership of this blog. Thank you for your support!

This week, we are sharing a report by Drs. Koketsu and Iiada from the School of Agriculture in Kanagawa, Japan. Their study focuses on the best predictors of lifetime performance in a breeding herd.

Key points

  • This review characterizes components of sow lifetime performance (longevity, prolificacy, fertility and lifetime efficacy) and its inter-relationships.
  • In the sow lifetime performance trees, annualized piglets weaned and annualized piglets born alive measured as lifetime efficiency are proposed as integrated measurements for sow lifetime performance.

Investigating PEDv Infections and Lessons to Improve Biosecurity in Finishing Pigs

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, we are reporting a collaborative work between the MSHMP team and Dr. Donna Drebes from Seaboard Foods regarding PEDv infections in finishing sites and its impact on biosecurity.

Understanding PRRSv diversity at the pig and litter level

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, Dr. Mariana Kikuti from the MSHMP team is sharing results from a study using whole genome sequencing to assess PRRSv diversity within and across litters.

Key points

  • Viral diversity within the piglet population is generally small, but higher diversity was found in ORFs 4 and 5a.
  • Within animal consensus changes were observed in a period as short as 2 weeks, which means piglets might be going to the GF sites with different viruses than the ones identified closer to farrowing.

Bench system biosecurity compliance assessment: A pilot project

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 in collaboration with Pipestone Veterinary Services presents a pilot project on biosecurity compliance regarding the use of benches in swine farms.

Risk-based management of PRRS and PED

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.

Today, we are sharing the work of Dr. Kaushi Kanankege, post-doctoral associate in the VanderWaal lab.

Objective

We conducted a survey to determine swine industry perspectives on a) perceived importance of risk-modifying factors contributing to between-farm transmission of PRRS and PED, and b) prevention/mitigation measures that should be prioritized on a farm that was forecasted to be at high risk of breaking.
