Microbiome studies in swine systems: Challenges and opportunities(Part 2)

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 sharing part 2 of Dr. Gomez’s report on microbiome studies in swine. You may read part 1 over here if you missed last week.

Key points

  • Due to the nature of microbiome it cannot be studied separated from other relevant information and should be studied together with metabolomics, genomics, immunity and nutrition.
  • Development of models at different levels are needed to evaluate the effect on microbiome of different strategies and to evaluate the impact of microbiome changes on the pig gut health.

Best of Leman 2018 series #4: P. Thomas – Air filtration by the numbers

We launched a new series on the blog last year. 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.

We can find all of the presentations selected from last year’s conference on the blog here.

Our fourth presentation for this year is by Dr. Pete Thomas from Iowa Select Farms regarding air filtration in pig farms.

Microbiome studies in swine systems: Challenges and opportunities (Part 1)

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 sharing part 1 of a report on the microbiome in swine production, by Dr. Andres Gomez.

Key Points

  • Microbiome and more specifically the bacteria residing in the gut play multiple roles related with nutrition and health.
  • The study of swine gut bacteria is still in its early stages, and the field contains many possibilities exciting possibilities.
  • Funding and microbiome classification are two of the most important barriers to overcome in order to gain insight into the complex field of swine gut bacteria.

Effect of strain-specific maternally-derived antibodies on influenza A virus infection dynamics in nursery pigs

A new scientific article from the Torremorell lab, about the influence of maternal antibodies on influenza dynamics was published in PLoS ONE.

The study followed 10 cohorts of nursery piglets form a single influenza-positive sow farm and compared influenza dynamics based on the vaccination status of the dam.

Understanding PRRSV Infection Dynamics in Growing Pigs in Control and Elimination Programs

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 sharing a report by Dr. Jose Angulo regarding PRRS infection dynamics in growing pigs.

Key Points

  • Growing pigs play an important role in regional PRRSV spread.
  • There was an association between prevalence of PRRSV infection in growing pig sites and risk of outbreaks in sow farms.
  • Learning about PRRSV infection dynamics in growing pigs and associated risk factors should help manage pig flows to minimize PRRSV incidence and /or risk of dissemination.
