Chapter 2 Metabolism and population dynamics of the intestinal microflora in the growing pig

摘要: Publisher Summary This chapter discusses the available information on population dynamics of intestinal flora in growing pigs and addresses factors involved changes this during different stages animal's life health disease. The contains several hundred microbial species, mostly strict anaerobes. A great amount these bacteria reside large intestine that adult consists mainly Gram-positive such as cocci, lactobacilli, eubacteria, clostridia. composition microflora is a result interaction between microorganisms colonize gut physiology pigs. While part constantly present (resident flora), some have short residence dynamically change microflora. stability diversity has tremendous role maintaining status pigs, especially suckling post-weaning period. digestive tract newborn piglet specialized diet comprising milk. Therefore, high lactase activity small intestine, at least for long milk comprises dominant feed source. methods, including molecular-based techniques, are to detect identify unculturable bacterial gut, there need more advanced techniques measure functional normal response dietary environmental stress.
