Effect of sialyllactose on growth performance and intestinal epithelium functions in weaned pigs challenged by enterotoxigenic Escherichia Coli.

ABSTRACT:

Background

Sialyllactose (SL) is one of the most abundant oligosaccharides present in porcine breast milk. However, little is known about its effect on growth performance and intestinal health in weaned pigs. This study was conducted to explore the protective effect of SL on intestinal epithelium in weaned pigs upon enterotoxigenic Escherichia coli (ETEC) challenge.

Methods

Thirty-two pigs were randomly divided into four treatments. Pigs fed with a basal diet or basal diet containing SL (5.0 g/kg) were orally infused with ETEC or culture medium.

Results

SL supplementation elevated the average daily gain (ADG) and feed efficiency in the ETEC-challenged pigs (P < 0.05). SL also improved the digestibilities of dry matter (DM), gross energy (GE), and ash in non-challenged
