Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...

Area of Science:

  • Animal Science
  • Microbiology
  • Nutrition

Background:

  • The intestinal microbiota is a complex bacterial community crucial for host health.
  • Maintaining intestinal homeostasis is vital for piglet health and development.
  • Gut microbiota is influenced by various factors, including diet.

Purpose of the Study:

  • To review the role of gut microbiota in weaned piglets.
  • To explore nutritional interventions using plant-derived polysaccharides and dietary fibers.
  • To highlight the potential of these compounds as non-antibiotic alternatives.

Main Methods:

  • Literature review on gut microbiota in piglets.
  • Analysis of studies on nutritional interventions with plant-derived polysaccharides and dietary fibers.
  • Examination of the correlation between polysaccharide structure and biological activity.

Main Results:

  • Supplementation with plant-derived polysaccharides (e.g., from alfalfa, licorice, wolfberry, ginseng, astragalus) and dietary fibers (e.g., inulin, pectin, beta-glucans) improves gut microbiota.
  • These interventions enhance beneficial microbes, reduce gastrointestinal infections, and decrease diarrhea incidence.
  • Improved gut health and growth performance are observed in weaned piglets.

Conclusions:

  • Plant-derived polysaccharides and dietary fibers are effective non-antibiotic alternatives for modulating gut microbiota in weaned piglets.
  • Understanding the structure-activity relationship of polysaccharides can optimize their use.
  • These findings support the development of novel strategies for piglet gut health management.
