Effects of Dietary Probiotics Supplementation on Growth Performance and Fecal Gas Emmission in Nursing and Finishing Pigs

摘要: For the Exp. 1, a total of seventy two pigs (10.530.02kg average initial body weight) were used in 38-d growth assay to determine effects Saccharomyces cerevisiae (SC) supplementation on performance and fecal microbial populations. Dietary treatments included 1) CON (corn-dried whey-SBM based diet), 2) SC0.2 (CON diet+0.2% SC) 3) SC0.4 diet+0.4% SC). Through entire experimental period, ADG, ADFI gain/feed not significantly different among treatments. At d 7 14 after onset experiment, Lactobacilli sp. count increased as concentration SC diets was (linear effect, P$0.45kg 28-d complex probiotics (CPB, Phichia anomala ST, Galactomyces geotrichum SR59, Thiobacillus sp.) performance, nutrient digestibility -N volatile fatty acid concentrations.
