Regulation of Food Intake01:30

Regulation of Food Intake

2.1K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Regulation of Metabolism

11.2K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Overview of Protein Metabolism

3.3K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Hormonal Regulation01:40

Hormonal Regulation

47.4K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

5.8K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Feedback Loops01:01

Feedback Loops

63.1K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Background:

  • Appetite, the desire for feed and water, is crucial for livestock productivity and health.
  • Economic traits like growth rate and muscle development in broilers are directly linked to appetite.
  • Environmental and animal-specific factors influence appetite, with early life being critical for feed preferences in fast-growing broilers.

Purpose of the Study:

  • To review the biological mechanisms underlying appetite.
  • To explore options for modulating appetite in broiler chickens.
  • To consider appetite optimization for sustainable and circular feed utilization.

Main Methods:

  • Literature review integrating data from human, animal, and bird models.
  • Analysis of biological mechanisms governing appetite regulation.
  • Consideration of factors influencing feed preferences and intake in poultry.

Main Results:

  • Appetite is a complex trait influenced by numerous biological and environmental factors.
  • Early life feed preferences significantly impact later intake and performance in broilers.
  • Understanding appetite mechanisms offers potential for improving broiler growth and feed efficiency.

Conclusions:

  • Modulating appetite presents a viable strategy for enhancing broiler chicken productivity.
