December 2019 – Swine in Minnesota

Effect of Single Dose of Antimicrobial Administration at Birth on Fecal Microbiota Development and Prevalence of Antimicrobial Resistance Genes in Piglets

It is the end of the year and to celebrate, here is one of the favorite Science Pages of the year, from Dr. Lowe’s team at the University of Illinois.

Keypoints

Early life antimicrobial prophylaxis had no effect on individual weight gain, or mortality but it was associated with minor shifts in the composition of fecal microbiota and noticeable changes in the abundance of selected Antimicrobial Resistant Genes
The shifts in fecal microbiota structure caused by perinatal antimicrobial intervention are modest and limited to particular groups of microbial taxa
Early life PPG and TUL intervention could promote the selection of Anrimicrobial Resistant Genes in herds

Podcast: Conversations around African Swine Fever

Happy holidays everyone! The swine group at the University of Minnesota wishes you the most wonderful time, surrounded by friends and family.

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

The latest episode of At the meeting… sees our hosts and their invited speaker talk about African Swine Fever: what is the current situation?

Characterization of Broadly Neutralizing Antibodies to PRRSV

This week, Dr. Jordan Young from the late Dr. Murtaugh‘s lab shares his latest research project regarding the immune response against PRRS.

Key point

PRRSV antibodies were determined to be broadly binding, but only homologously neutralizing, suggesting a polyclonal response, involving multiple PRRSV specific antibodies might be necessary for PRRSV neutralization.
This means that vaccinations aiming to protect from infection likely need to involve exposure to multiple strains of PRRSV to induce a broad protective immunity, rather than relying on single-strain vaccines.

Best of Leman 2019 #2: J. Nerem and J. Schwartz – Investigating silent estrus in gilts

Our second selection from the past Leman conference is actually two presentations from practitioners regarding silent estrus in gilts. Dr. Joel Nerem works in Pipestone Veterinary Services and Dr. Jake Schwartz is with Swine Vet Center. Both share their experience dealing with this issue.
