Porcine reproductive and respiratory syndrome prevalence and processing fluids use for diagnosis in United States 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.

In this Science Page we look at research conducted by Mariana Kikuti, Carles Vilalta, Juan Sanhueza, Claudio Marcello Melini, and Cesar Corzo from the MSHMP team. They look at PRRS prevalence and how the use of processing fluids can help diagnose the disease.

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.
