What is Monogastric Digestion?

70.5K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

376
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 Intestines

71.3K
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...

Area of Science:

  • Microbiology
  • Metagenomics
  • Animal Science

Background:

  • Understanding the chicken gut microbiome is crucial for poultry health and productivity.
  • Previous studies have often been localized, lacking a global perspective on microbial community composition.

Purpose of the Study:

  • To characterize the global chicken gut microbiota, including its core members.
  • To assess the influence of gastrointestinal tract (GIT) site, bird breed, age, and geographical location on microbial composition.
  • To establish a baseline for 'normal' poultry gut microbiota.

Main Methods:

  • Compiled and analyzed metataxonomic 16S ribosomal DNA sequence data from 602 global studies via the MGnify pipeline.
  • Utilized PERMANOVA analysis to determine the significance of various factors on microbial diversity.

Main Results:

  • Identified 3 phyla, 25 families, and 30 genera, with core genera including Lactobacillus, Faecalibacterium, and Eisenbergiella.
  • GIT site, bird breed, age, and geographical location significantly affected microbial diversity.
  • Microbial composition varied by GIT site (e.g., caeca vs. feces), breed, age, and geographic origin.

Conclusions:

  • This study provides a global definition of chicken gastrointestinal tract microbiota.
  • Understanding these variations is essential for optimizing poultry production and environmental sustainability.
  • The findings highlight the importance of considering multiple factors when studying the chicken microbiome.
