Implementing Biosecurity On Nursery-Grow-Finish Sites: A podcast

Thank you for your interest in this archived blog post. The link below may not work anymore, but you can access older episodes of “At the Meeting” at the podcast’s website!

Dr. Tyler Te Grotenhuis (Christensen Farms) and Dr. Mike Eisenmenger (recently retired from the Swine Vet Center) discuss with the At The Meeting team how to implement biosecurity on nursery-grow-finish sites.

Antimicrobial use in wean to market pigs in the United States

Today, we are sharing a publication from Drs. Davies and Singer regarding antimicrobial use in wean-to-market pigs in the United States based on self-reported data from swine producers and veterinarians. This work is published in Zoonoses and Public Health in open access.

Impacts

Demonstrates the feasibility of obtaining data on antimicrobial use in the United States swine industry through sharing of proprietary records within industry.
Provides the first substantial description of antimicrobial use in United States swine beyond annual sales and distribution data.
Indicates that specific metrics of antibiotic use that focus on conditions within individual industries will be most useful to advance stewardship.

Effects of reduced nocturnal temperature on pig performance and energy consumption in swine nursery rooms

The swine extension team at the University of Minnesota has a podcast available through the Apple platform. If you have additional free time these days, you may want to check their latest episode on nursery temperature settings and their impact on pig performances!

PRRSv ORF5 difference from VR2332 by herd type

This week, the MSHMP team assessed differences in ORF5 sequences compared to VR2332 based on the type of farm, the sequence was collected at.

Key points

Breeding herd sequences differ 8%-16% while in other herd types they differ 1%-15% from VR2332 at the ORF5 level.
The larger nucleotide identity (%) range compared to VR2332 in growing pigs suggests a higher viral diversity within this group.

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.
