Strep suis continuously challenges US herds

It’s not unrealistic to say that if you checked the nasal cavities or tonsils of any group of pigs, you would find Strep suis. It is on virtually every hog farm.

Study sheds light on antimicrobial use in US wean-to-market pigs

The findings of a recent study show it’s feasible to obtain data on antimicrobial use while keeping information confidential.
