Background

Daily feeding of effective probiotics has been repeatedly demonstrated to support normal gastrointestinal (GI) functions and a beneficially balanced gut microbiome in sows, piglets, and growing pigs. This subject was recently reviewed by Liao and Nyachoti, 20171. Aside from the typical array of GI functions that are positively affected by probiotics, namely digestion, absorption, barrier, and immune functions, there is a growing body of evidence that other organ systems, e.g. the lungs2, may derive benefits from the actions of probiotics and a healthy gut microbiome.

Purpose

The purpose of this study was to determine the effect of daily feeding of BIOPLUS® 2B to sows from 31 days pre-farrowing through weaning on their performance and that of their litters and to determine the effect of continued daily feeding of BIOPLUS® 2B to piglets through 28 days post-weaning in the presence of a severe challenge with PRRSv.
