Optimal Foraging00:48

Optimal Foraging

11.8K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Protein Digestion01:02

Protein Digestion

86.3K
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Key Elements for Plant Nutrition

17.9K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Regulation of Food Intake01:30

Regulation of Food Intake

2.8K
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

1.1K
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Summary

Pig feed preference is linked to digestible nutrients like starch, not fiber. Pigs prefer cereals with higher digestible starch and lower crude fiber content for better feed intake.

Area of Science:

  • Animal Science
  • Nutritional Science
  • Swine Nutrition

Background:

  • Understanding cereal feed preference in pigs is crucial for optimizing diet formulation and animal performance.
  • Previous studies identified 25 cereals with known preference levels when included at 60% in complete feed.

Purpose of the Study:

  • To identify the specific nutritional characteristics of cereals that best predict pig feed preference.
  • To correlate nutrient profiles and digestibility with observed cereal preferences in swine diets.

Main Methods:

  • Nutritional analysis of 25 cereals for dry matter (DM), organic matter (OM), crude fiber, ether extract, crude protein (CP), gross energy (GE), digestible starch, and glycemic index.
  • Digestibility trials using ileal cannulated pigs to determine apparent ileal digestibility (AID) and total tract digestibility (ATTD) of nutrients in 12 selected cereal-based feeds.
  • Principal component (PC) analysis to explore relationships between nutritional components and correlation analysis with feed preference data.

Main Results:

  • Cereal preference was negatively correlated with crude fiber content and positively correlated with digestible starch and glycemic index.
  • Digestibility data revealed significant positive relationships between feed preference and digestible nutrients (starch, DM, OM) and negative relationships with nondigestible components.
  • Apparent total tract digestibility of DM and OM, and AID of starch were strong predictors of cereal preference in pigs.

Conclusions:

  • Pig cereal feed preference is primarily driven by the content of digestible nutrients, particularly starch.
  • Reducing nondigestible components like crude fiber in cereal-based feeds can enhance palatability and intake in pigs.
  • Nutritional strategies focusing on digestible energy sources are key to improving cereal feed selection in swine.
