Anatomy of the Intestines

Anatomy of the Intestines

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...

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Types of Genetic Transfer Between Organisms

Types of Genetic Transfer Between Organisms

Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Area of Science:

Poultry Science
Microbiology
Animal Reproduction

Background:

The gut microbiome is crucial for breeder hen reproductive efficiency, egg quality, and progeny development.
Microbiome composition is influenced by host genetics, age, diet, and management practices.
The breeder gut microbiome is dynamic and can be modulated by interventions.

Purpose of the Study:

To explore the role of the breeder hen gut microbiome in reproductive performance.
To understand the impact of maternal microbiome on offspring development.
To highlight the potential of microbiome-based strategies in poultry production.

Main Methods:

Review of existing literature on breeder hen gut microbiota.
Analysis of factors influencing microbiome composition.
Examination of microbial transmission pathways (vertical transmission).
Evaluation of maternal nutritional strategies and their effects on progeny microbiota.

Main Results:

Maternal gut microbes are vertically transmitted to offspring, influencing early gut maturation, immunity, and growth.
The yolk sac acts as a reservoir for microbes crucial for progeny development.
Maternal nutrition can program the gut microbiota and intestinal development of offspring.
Targeted interventions can enhance intestinal health and laying performance in breeder hens.

Conclusions:

The breeder gut microbiome is a key determinant and mediator of transgenerational performance in poultry.
Microbiome-focused approaches offer potential for improving reproductive success and sustainability in poultry production.
Understanding and manipulating the breeder microbiome is vital for efficient poultry farming.
