BACKGROUND This study was conducted to evaluate the health benefits to weaning pigs, raised under low sanitary conditions, of dietary supplementation with a multi‐strain yeast fraction product ( Cyberlindnera jadinii and Saccharomyces cerevisiae ). In total, 160 weaning pigs (7.21 ± 1.05 kg) were randomly allotted to two dietary treatments in a 6‐week feeding trial. The dietary treatments included a corn‐soybean meal‐based basal diet (CON) and CON + 2 g kg −1 multi‐strain yeast fraction product (MsYF) during weeks 1–2 and 0.4 g kg −1 MsYF during weeks 3–6. RESULTS The MsYF supplementation increased ( P < 0.05) body weight (BW) at day 42 and average daily gain (ADG) during days 1–14 and days 1–42 ( P < 0.05) compared to CON. The total tract digestibility of dry matter (DM), fecal Lactobacillus counts, and serum immunoglobulin G (IgG) concentration at day 42 were higher ( P < 0.05) in pigs fed a MsYF supplemented diet. The concentration of serum haptoglobin in pigs receiving a MsYF‐supplemented diet was higher ( P < 0.05) at days 7, 14, and 42 than those receiving CON. The mRNA expression for INF‐ γ and TNF‐ α genes were lower ( P < 0.05) at days 14 and 7 respectively and the expression of IL‐6 and TLR‐2 genes was lower ( P < 0.01) at days 7 and 14 in pigs fed an MsFY supplemented diet than those fed CON. CONCLUSION Supplementation with a multi‐strain yeast fraction product had a positive effect on ADG during the early post‐weaning period and led to better health in weaning pigs. © 2019 Society of Chemical Industry
