摘要：

The changes of ileal bacterial microbiota in pigs during the first 2 weeks post-weaning in response to feeding lincomycin, organic acids or herbal extract were characterized using 16S rRNA gene-based PCR-denatuxing gradient gel electrophoresis (DGGE) profiling, DNA sequencing, and real-time PCR (QPCR) techniques. Both time post-weaning and the dietary treatments resulted in a shift of the microbiota. composition. While time post-weaning mostly influenced Clostridium group, the feed additives increased the population of Lactobacillus and related lactic acid bacteria by >= 3-fold.
