    Summary

    Iron deficiency in piglets did not affect D-xylose absorption unless diarrhea was present. Iron deficiency impaired intestinal structure, particularly in piglets with diarrhea, impacting nutrient absorption.

    Area of Science:

    • Animal Physiology
    • Nutritional Science
    • Gastroenterology

    Background:

    • Iron deficiency is a common nutritional disorder in piglets.
    • Intestinal function and morphology can be affected by nutritional status.
    • Understanding the impact of iron deficiency on nutrient absorption is crucial for animal health.

    Purpose of the Study:

    • To investigate the effect of iron deficiency on D-xylose absorption in piglets.
    • To assess the impact of iron deficiency on fecal composition.
    • To examine the small intestinal morphology in iron-deficient piglets, particularly in the presence of diarrhea.

    Main Methods:

    • D-xylose absorption tests were performed on iron-deficient and iron-sufficient piglets.
    • Fecal samples were analyzed for dry matter and fat content.
    • Histological examination and morphometric analysis of small intestinal tissues were conducted.

    Main Results:

    • D-xylose absorption was similar between iron-deficient and iron-sufficient piglets, except when diarrhea was present.
    • Iron deficiency led to increased fecal fat content and decreased dry matter.
    • Diarrhea in iron-deficient piglets exacerbated fecal fat excretion and was associated with villous atrophy and reduced mucosal complexity.

    Conclusions:

    • Iron deficiency alone does not significantly impair D-xylose absorption in piglets.
    • Diarrhea in iron-deficient piglets severely impacts intestinal function and morphology, leading to malabsorption.
    • Iron supplementation may be critical for maintaining intestinal integrity and function in piglets, especially during disease outbreaks.
