Post-weaning diarrhea is the most common cause of piglet mortality leading to significant economic loss in pork production. Feed supplements given to weaned piglets have been shown to reduce post-weaning diarrhea, improve growth, and aid in intestinal and overall health during the post-weaning period. Beta-glucans, a soluble fiber derived from bacteria, barley, oats and yeast can alter the intestinal microbiome and decrease the incidence of diarrhea. Thus, this research was conducted to investigate how beta-glucan containing feed supplements could potentially promote intestinal health through altering the gut microbiome. For this study we investigated the impact of supplementing piglet feed with yeast (Saccharomyces cerevisiae) or whole ground oat alone or in combination had on the gut microbiome of weaned piglets over time. Weaned piglets (n=3) were divided into four diet groups: (1) control, (2) Yeast Culture (YC) (5g/kg), (3) (15%) Oat, (5) YC (5g/kg) + (15%) Oat (YCO). On weaning day (day 0) and days 1, 4, 7 and 11 post- weaning, contents of the small and large intestines were collected. Microbial community compositions were determined through 16S rRNA analysis, with data processing using Quality Insights Into Microbial Ecology (QIIME) versions 1 and 2. Significance on taxon changes over time were evaluated as P<0.05. Contrasts were conducted with the control diet for the three treatment diets. All treatment diets showed Streptococcaceae to be at lower levels in both large and small intestines. For the large intestine, reduction over time was found for Bacteriodaceae and Porphyromonadaceae for Oat, YC, and YCO, Paraprevotellaceae for Oat and YCO, and Spirochaetaceae for Oat. Lachnospiraceae increased in the large intestine over time for Oat, YC, and YCO. These results suggest that dietary treatments with oats and yeast have some limited effect on the microbiome post-weaning, and may be part of future strategies concerning dietary supplementation.
