Effects of Saccharomyces cerevisiae cell wall extract and poplar propolis ethanol extract supplementation on growth performance, digestibility, blood profile, fecal microbiota and fecal noxious gas emissions in growing pigs.
A total of 105 growing pigs (24.91 ± 1.06 kg) were used in a 6-week trial to investigate the effects of including Saccharomyces cerevisiae cell wall extract and poplar propolis ethanol extract (SPE) in the diet on growth performance, digestibility, blood profiles, fecal microbiota and fecal noxious gas emissions. Pigs were randomly allocated to one of three dietary treatments (seven pens/treatment, five pigs/pen) according to initial body weight and sex (two gilts and three barrows). Treatments consisted of a corn soybean meal basal diet supplemented with 0, 0.05 or 0.10% SPE. There was a significant linear improvement (P < 0.05) in average daily gain, gain/feed, the apparent total tract digestibility of dry matter, nitrogen, and gross energy, blood lymphocyte percentage, immunoglobulin G concentration, fecal Escherichia coli and Lactobacillus counts as well as fecal NH3 and H2 S emissions associated with the inclusion of SPE in the diet. Average daily feed intake, red blood cells and white blood cells concentration were not significantly (P > 0.05) affected by SPE supplementation in the diets. In conclusion, results indicate that dietary SPE supplementation can improve growth performance, digestibility and fecal microbiota, and decrease fecal gas emissions in growing pigs.
