Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

670
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines01:23

Anatomy of the Intestines

74.3K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Bacterial Phylum Firmicutes01:27

Bacterial Phylum Firmicutes

190
Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...

Area of Science:

  • Poultry nutrition and gut microbiome research.
  • Animal science and microbiology.

Background:

  • Gut microbiota plays a crucial role in poultry health, nutrition, and production.
  • Understanding the influence of dietary components like fiber is essential for optimizing broiler performance.

Purpose of the Study:

  • To investigate the effects of varying dietary fiber levels, using alfalfa, on the cecal microbiota composition and function in Dahen broilers.
  • To identify specific microbial communities and metabolic pathways influenced by dietary fiber.

Main Methods:

  • 16S rRNA gene sequencing was employed to analyze cecal microbiota profiles.
  • Gas chromatography was used to assess microbial functions, including short-chain fatty acid (SCFA) production.

Main Results:

  • Increased dietary fiber levels significantly enhanced gut microbiota diversity in broilers.
  • Specific bacterial genera, including Rikenellaceae RC9 gut group, Faecalibacterium, Prevotellaceae UCG 001, and Ruminococcaceae UCG 014, were stimulated by dietary fiber.
  • Altered microbial functions included carbohydrate metabolism and genetic information processing, with Anaerofilum and Dielma genera correlating with SCFA production.

Conclusions:

  • Dietary fiber level is a key modulator of broiler gut microbiota composition and function.
  • The observed alterations in microbiota may mediate beneficial effects on broiler production, underscoring the potential of dietary fiber in poultry management.
